===============
1) Introduction
===============


QuickBMS is a multiplatform extractor engine that can be programmed
through some simple textual scripts, it's intended for extracting files
and information from the archives of any program and moreover games.

The script language from which QuickBMS is derived is MexScript
documented here: http://wiki.xentax.com/index.php/BMS
So QuickBMS is FULLY compatible with that original syntax and all the
scripts that were created here:
http://forum.xentax.com/viewtopic.php?t=1086

QuickBMS supports also the WCX plugins of Total Commander:
  http://www.totalcmd.net/directory/packer.html
  http://www.ghisler.com/plugins.htm

I improved the original BMS language for:
- removing some implied fields, like the file number in some commands
- adding new commands, like Encryption
- adding new behaviors and features, like negative GoTo
These improvements allow QuickBMS to work with tons of simple and
complex formats and even doing things like modifying files, creating
new files with headers, converting files and reimporting files back in
their original archives.

The tool is open source under the GPL license and works on both Windows
and Linux and on both little and big endian architectures like Intel
and PPC.
Basically it means that you can distribute the original quickbms.exe
file as you desire but reusing its source code or modifying it may
require you to adopt the same open source license.

The official homepage of QuickBMS is:

  http://quickbms.aluigi.org

In case it doesn't work try:

  http://aluigi.altervista.org/quickbms.htm

There is also an official forum where I provide support for Quickbms
and help with file formats:

  http://zenhax.com

QuickBMS is perfect for those works in which you need a quick way to
extract information from files and at the same time you would like to
reinject them back without writing a standalone tool to do both the
works (extraction and rebuilding).
This is particularly useful if you have 100 different types of archives
to analyze (reverse engineering), parse and then sharing your tools
with your community.

A BMS script is just a text file so you can paste it in a forum, or in
paste-bin or anywhere you desire.

For Linux users there is a Makefile in the src folder, the only
requirements are openssl, zlib, bzip2 and lzo while the optional
components are ucl, mcrypt and tomcrypt (uncomment the commented line
near the end of the Makefile to enable them).
If your distro supports apt-get and you have problems during the usage
of "make", try the following:

  apt-get install gcc g++ zlib1g-dev libbz2-dev libssl-dev liblzo2-dev unicode

In case of problems on 64bit versions of Linux, try also to append a
":i386" to the previous dependencies, like:

  apt-get install libssl-dev:i386 libbz2-dev:i386 liblzo2-dev:i386

2) Usage
========


Simple and quick:

- double-click on quickbms.exe

- select the script or the plugin for the type of archive you want to
  extract, for example zip.bms if it's a zip file.

- select the input archive or multiple files.
  you can also select a whole folder by entering in it and then typing
  * (or "" on systems before Windows 7) in the "File name:" field, and
  then select Open.
  You can even use * to set wildcards, for example *.txt or *required_name*
  or prefix*suffix

- select the output folder where extracting the files.
  you can specify any filename, it will be ignored because only the
  directory is taken

- watch the progress status of the extraction

That's the simple "GUI" usage but QuickBMS can do various other things
when launched from the console, in fact it supports many command-line
options for advanced users and for who writes the scripts.
You can view all the available options simply launching QuickBMS from
command-line ("cmd.exe" on Windows) without arguments.
The following is the current list of options:


    Usage: quickbms.exe
             [options]
               <script.BMS>
                 <input_archive/folder>
                   [output_folder]

    Options:
    -l     list the files without extracting them
    -f W   filter the files to extract using the W wildcards separated by comma or
           semicolon, example -f "*.mp3,*.txt;*myname*"
           if the filter starts with ! it's considered an ignore filter
           the filter can be also a text file containing filters
           example: quickbms -f "*.mp3;!*.ogg" script.bms archive.dat output
           example: quickbms -f myfilters_list.txt script.bms archive.dat
           please use {} instead of * to avoid problems on Windows, you can also
           use multiple -f if you feel more comfortable
    -F W   as above but works only with the files in the input folder (if used)
           example: quickbms -F "*.dat" script.bms input_folder output_folder
    -o     if the output files already exist this option will overwrite them
           automatically without asking the user confirmation
    -k     keep the current files if already exist without asking (skip all)
    -r     experimental reimport option that should work with many archives:
             quickbms script.bms archive.pak output_folder
             modify the needed files in output_folder and maybe remove the others
             quickbms -w -r script.bms archive.pak output_folder
           you must read section 3 of quickbms.txt before using this feature
    -u     check if there is a new version of QuickBMS available
    -i     generate an ISO9660 file instead of extracting every file, the name of
           the ISO image will be the name of the input file or folder
    -z     exactly as above but generate a ZIP file

    Advanced options:
    -d     automatically create an additional output folder with the name of the
           input folder and file processed, eg. models/mychar/mychar.arc/FILES,
           -d works also if input and output folders are the same (rename folder)
    -D     similar to -d but will not create the folder with the filename
    -E     experimental option for automatically reversing the endianess of any
           file simply reading it field by field (so each get will produce a put)
    -c     quick list of the basic BMS commands and some notes about this tool
    -S CMD execute the command CMD on each file extracted, you must specify the
           #INPUT# placeholder which will be replaced by the name of the file
           example: -S "lame -b 192 -t --quiet #INPUT#"
    -Y     automatically answer yes to any question
    -O F   redirect the output of all the extracted files to the file F
    -s SF  add a script file or command before the execution of the input script,
           useful if an archive uses a different endianess or encryption and so on
           SF can be a script or directly the bms instruction you want to execute
    -.     don't terminate QuickBMS if there is an error while parsing multiple
           files (like wrong compression or small file), just continue with the
           other files in the folder

    Debug and experimental options:
    -v     verbose debug information, useful for verifying possible errors
    -V     alternative verbose output, useful for programmers
    -q     quiet, no *log output
    -Q     very quiet, no output except the Print command
    -L F   dump the offset/size/name of the files inside the file F
    -x     use the hexadecimal notation in myitoa (debug)
    -0     no extraction of files, useful for testing a script without using space
    -R     needed for the programs that act as interface for QuickBMS
    -a S   pass arguments to the input script that will take the names
           quickbms_arg1, quickbms_arg2, quickbms_arg3 and so on, note that they
           handled as arguments so pay attentions to spaces and commas, eg:
             -a "arg1 \"arg 2\", arg3"
             -a arg1 -a "\"arg 2\"" -a arg3
    -H     cool HTML hex viewer output, use it only with very small files!
    -X     cool hex viewer output on the console (support Less-like keys)
    -9     toggle XDBG_ALLOC_ACTIVE  (enabled)
    -8     toggle XDBG_ALLOC_INDEX   (enabled)
    -7     toggle XDBG_ALLOC_VERBOSE (disabled)
    -6     toggle XDBG_HEAPVALIDATE  (disabled)
    -3     execute an INT3 before each CallDll, compression and encryption
    -I     toggle variable names case sensitivity (case insensitive)
    -M F   experimental compare and merge feature that allows to compare the
           extracted files with those located in the folder F, currently this
           experimental option will create files of 0 bytes if they are not
           different, so it's not simple to identify what files were written

    Features and security activation options:
    -w     enable the write mode required to write physical input files with Put*
    -C     enable the usage of CallDll without asking permission
    -n     enable the usage of network sockets
    -p     enable the usage of processes
    -A     enable the usage of audio device
    -g     enable the usage of video graphic device
    -m     enable the usage of Windows messages
    -G     force the GUI mode on Windows, it's automatically enabled if you
           double-click on the QuickBMS executable


Remember that the script and the input archive/folder are ever REQUIRED
and they must be specified at the end of the command-line.

The following is an example for listing all the mp3 files from the input
archive:

  quickbms -l -f "*.mp3" zip.bms myfile.zip
  quickbms -l -f "{}.mp3;{}.ogg" zip.bms myfile.zip
  quickbms -l -f "*.mp3;*.ogg,*filename*" zip.bms myfile.zip
  quickbms -l -f file_containing_the_filters.txt zip.bms myfile.zip

So -l for listing the files without extracting them, and -f for
filtering the archived files. Regarding the -f and -F options it's worth
to note that both * and {} are accepted as wildcards because the first
pattern may be interpreted by the Windows console.

QuickBMS supports also a folder as input which means that with a single
command it's possible to unpack all the archives of a whole game
directly using QuickBMS.

Imagine to use the zip.bms script with all the zip files located in the
Program Files folder:

  quickbms -F "*.zip" zip.bms "c:\Program Files (x86)" c:\output_folder

Note: as said before, sometimes Windows doesn't like the * char even if
      used between quotes, so in case of problems with "*.zip" you can
      use {} instead of *, for example "{}.zip"

Except for -l, -f, -F and maybe -o and -s options, the others are
intended for debugging, or they are special features or switches to
enable/disabe some internals, so they should be ignored by the common
users.

If the extraction with a particular script is too slow or scanning a
folder takes too much memory and time try using the -9 option that
disables the memory protection.

You can apply these options directly in a shortcut to quickbms.exe in
the Target field of its properties, so you can use the double-click
"GUI" method and all the command-line options you desire without
using the command-line.

In the same quickbms.zip package you should find
also quickbms_4gb_files.exe (previously known as quickms64_test.exe)
that is an "experimental" version that uses 64bit numbers instead of
the original 32 bits:
- it supports archives and files bigger than 4 gigabytes
- it may have problems to work with "some" scripts
- it's a native 32bit application so it works on both Windows 32 and 64
- it's experimental and so not much supported, problems like crashes
  and incorrect math operations can happen often in some scripts

---

Advanced users could find useful also these specific options:

-d Automatically creates a folder with the name of the input file where
   placing all the files, it's useful if you have many small archives
   containing the same filenames and you need a way to separate the
   extracted files without overwriting or renaming them.

-E If you have a bms script that simply reads a file format, you can
   change the endianess of all its numeric fields on the fly by simply
   using this option.
   For example if you have a "get SIZE long" a 32bit number will be
   read as usual and additionally it will be reversed (0x11223344 to
   0x44332211 or viceversa) and placed at the same location.
   Remember that you need to specify also the -w option with physical
   files, alternatively you can save the whole file in a memory file
   and then dumping it so that -w is not necessary.
   With this option is really trivial to convert the endianess of files
   between different platforms, like Xbox 360 and PC.

==================================
3) Reimporting the extracted files
==================================


QuickBMS is mainly an extraction tool, but it supports also the -r
option that converts the tool in a simple reimporter/reinjector and so
it may be useful for modding or translating a game.

The idea consists of being able to reimport ("injecting back") the
modified files in the original archives without touching a single line
of the script, just reusing the same bms scripts that already exist!


-----------------------------------------------------------------------


Using this feature is really trivial and the following is a
step-by-step example:

- Make a backup copy of the original archive!

- Extract the files or only those you want to modify (-f option) as you
  do normally via the GUI (double-click on quickbms.exe) OR via
  command-line like the following example:

    quickbms script.bms archive.pak output_folder

- Modify the extracted files leaving their size unchanged or smaller
  than before.
  I suggest to delete the files that have not been modified so that the
  reimporting process will be faster and safer. In the folder leave
  only the files you modified.
  Remember that their size must be smaller or equal than the original!

- Reimport the files in the archive via the GUI by clicking on the
  file called "reimport.bat" OR via command-line:

    quickbms -w -r script.bms archive.pak output_folder

- Test the game with the modified archive

Remember that you can use the GUI for the reimporting procedure, just
click on "reimport.bat" found in the quickbms package, it contains the
command: quickbms.exe -G -w -r.


-----------------------------------------------------------------------


Another example:
- First step, use QuickBMS as usual:

  archive.pak -> file1.txt
              -> file2.dat
              -> file3.jpg

- Second step:
  - delete file1.txt and file2.dat
  - modify file3.jpg, for example adding a "smile" in it
  - save file3.jpg and be sure that it's size is SMALLER or EQUAL than
    the original

- Third step, use the reimport.bat file provided in quickbms and select
  the SAME file and output folder you selected in the first step:

  archive.pak <- file1.txt  (doesn't exist so it's not reimported)
              <- file2.dat  (doesn't exist so it's not reimported)
              <- file3.jpg  (successfully reimported)


-----------------------------------------------------------------------


Some important notes about this particular reimporting process:

- you CANNOT increase the size of the files you want to reimport, so
  the new files must be smaller or equal than the original ones.

- the reimport process of compressed files may be slower in some cases,
  for example with zlib, deflate, lzma and few others that are optimized
  to use less space as possible at cost of CPU and time.

- for the maximum compatibility within the thousands of available file
  formats I decided to not use tricks for modifying the original
  size and compressed_size values.
  for example imagine those formats that use encrypted information
  tables or MEMORY_FILEs for such tables or that use things like
  "math SIZE *= 0x800".
  the reimport process must be generic and without work-arounds.

- the script is just the same for both extraction and reimporting, it
  means that many of the scripts written by me and the other users
  already work, cool!

- the reimporting of compressed files is perfectly possible because
  the tool automatically switches to the relative compression algorithm
  if available (for example deflate -> deflate_compress), if an
  algorithm is not available in recompress mode then the reimporting
  will fail

? if the original archive uses complex encryptions that require the
  usage of MEMORY_FILEs to perform temporary decryption, then it's NOT
  supported and the same is valid for chunked content (like those
  scripts that use the command Append)
  From version 0.6.6, QuickBMS has an experimental mode for reimporting
  chunked files, it works very well with files saved directly to disk
  and less well with those that use MEMORY_FILEs (most of my scripts).
  In my opinion this feature is great but don't expect too much, with
  some scripts you can have success but many others may not work.

- FileXor, FileRot, Encryption and Filecrypt should work correctly

- things like CRCs and hashes can't be supported

- it's possible to reimport also the nameless files (log "" OFFSET SIZE)
  the tool will automatically check for files in the folder with the
  same number so if the file was saved as 00000014.xml it will be
  reimported perfectly.

- the reimport mode doesn't work if you renamed the files with the same
  name during the extraction (for example using the 'r' choice), in
  this case there is no way for the tool to know the correct file to
  reimport and will reimport only the one with the same original name.


Please note that often the games are able to load the extracted files
directly from their installation folder, sometimes directly maybe by
just removing the original archive and other times by launching the
game with specific command-line arguments.
The reimport feature of QuickBMS has already allowed to slightly mod
and translate various games, but it's meant as a quick or temporary
solution till a proper stand-alone rebuilder tool is written by the
community of the target game, due to the better benefits coming from a
complete and specific solution.
But if nobody is going to write a stand-alone rebuilder for a specific
game, then the reimport feature of QuickBMS is a great and immediately
available solution.

===============================================
4) How to create scripts (for developers only!)
===============================================


Originally the tool was created just for myself to be able to write
quick extractors for simple archives immediately without writing a new
tool, but QuickBMS revealed to be a powerful tool that I use for many
tasks, including the parsing of some protocols and much more.

So, how to write these scripts?
Well I guess that giving a look at http://wiki.xentax.com/index.php/BMS
is a good first step to understand at least the basis of this language
originally written by Mike Zuurman (alias Mr.Mouse of XeNTaX) in the
far 1997.
Then it's good to take a look at the various examples provided on
http://quickbms.aluigi.org and http://zenhax.com

A programming knowledge and background is not required but it's very
useful for understanding the "logic" of the scripts and some terms.
What is really necessary is the full knowledge of the format to
implement: reverse engineering is ever useful for figuring the needed
fields.

Luckily in the extraction process it's not needed to know all the
fields of an archive, so a field like a CRC doesn't matter while the
important fields to extract a file are ever the following:

- filename
- offset
- size
- optional compressed size if the file is compressed

If you don't have filename and size, it's not a problem. What's really
necessary is knowing at least of the offsets of the files.
If you check my scripts you can notice the name DUMMY assigned to the
fields that are not useful for the extraction.

Note that I will try to keep the following documentation updated as
much as I can, and also in sync with what happens inside QuickBMS for
each command.
The source code of the tool is not easy to understand so I hope that
this documentation may be useful and complete.

The fields between [] are optional fields.

---

A quick and limited list of available commands is available when
QuickBMS is launched with the -c option.
The following are some important notes about the QuickBMS environment:

- Everything is considered a variable except if it starts with a number
  in which case it's considered a numeric constant, so when in this
  document I talk about VAR, STRING and other types of data I refer
  EVER to both variables and constants because they are EXACTLY the
  SAME thing inside the tool.

- All the commands and the names of the variables are case INsensitive
  so "get OFFSET long" is the same as "GeT oFfSeT lOnG".

- Everything works with signed 32 bit numbers (-2147483648 to
  2147483647) so QuickBMS may not work well with files over 2 gigabytes
  but it can seek on files of 4 gigabytes without problems.
  Consider the following limits:
  - max 4gb size for archives
  - max 2gb size for the archived files
  You can try quickbms_4gb_files.exe for working with bigger archives.

- The constant strings depends by the context of the command, in fact
  in some commands they are handled as strings in C notation like
  "\x12\x34\\hello\"bye\0", in this case you must know how this
  representation works.
  This is a solution for using binary data inside the textual script.
  The keyword is "C language escape characters" or escape sequences,
  they are very simple, take a look here:
  http://msdn.microsoft.com/en-us/library/h21280bw%28VS.80%29.aspx
  http://www.acm.uiuc.edu/webmonkeys/book/c_guide/1.1.html
  ONLY some commands support this C string notation for the escape
  characters, a quick way to find them is searching the keyword
  "(cstring)" without quotes in this document.

- Both decimal and hexadecimal numbers are supported, hexadecimal is
  adopted if the number starts with 0x so 1234 and 0x4d2 are the same.

- Any operation made on fields bigger than 8 bits is controlled by the
  global endianess, it means that any number and unicode field is
  read in little endian by default otherwise it's valid the endianess
  specified with the Endian command.

- Comments can be used in C (// and /* */) and BMS syntax (#), for
  example:
    get DUMMY long  # this is a comment
    /*
    this is a comment
    */

- The FILENUM (file number) field in the commands is set as a constant,
  it means that it cannot be modified at runtime using a variable,
  examples:
    get TMP string 0    # ok
    get TMP string VAR  # wrong

- All the commands use variables for their arguments except those in
  which it's specified that a constant number or a string (STRING) is
  needed. For example the commands that use a C string (cstring) use
  constant strings and not variables, except some cases like the
  dictionary of ComType.
  Note that this behaviour may change in future or may have been
  already changed in some commands.


File numbers:
  Every file opened in QuickBMS has a number assigned to it, if this
  number is not specified it will be considered 0, the main input file.
  The first opened file is the input archive to which is assigned the
  number 0 (zero), the others must be opened with the Open command.
  Negative numbers are considered MEMORY_FILEs, so -1 is MEMORY_FILE,
  -2 MEMORY_FILE2 and so on.

MEMORY_FILEs:
  This is a particular type of temporary file which resides in memory
  and works exactly like a normal temporary file.
  It's extremely useful for doing many operations and you can use
  multiple memory files: MEMORY_FILE, MEMORY_FILE2, MEMORY_FILE3 and so
  on.
  MEMORY_FILE and MEMORY_FILE1 are the same file.
  .
  If you need to work with chunked parts of a file to concatenate to
  the memory file, you need to use the following trick:
  .
    putvarchr MEMORY_FILE FINAL_SIZE 0  # allocate memory internally in quickbms
    log MEMORY_FILE 0 0                 # create the file
  .
  The first instruction allocates the memory for containing the final
  size of your chunks, and the second one is necessary for resetting
  the memory file (current offset and size, not the allocated size).
  If you need to create a MEMORY_FILE of 0x100 bytes set to zero to
  use in CallDLL use the following
  .
    log MEMORY_FILE 0 0                 # create the file
    putvarchr MEMORY_FILE 0x100 0       # write 0x100+1 bytes set to zero

TEMPORARY_FILE:
  This additional file called TEMPORARY_FILE resides physically on the
  target folder and has that exact name.
  Although its "temporary" name, it's not deleted by the output folder
  and QuickBMS will ask to remove it at the end of the extraction.
  The file is created in any condition, even when it's used the -l (list)
  option for listing the files, so it's perfect in certain situations
  like when it's used a chunks based file system.
  The difference with the MEMORY_FILE is only related to the amount of
  memory available on the system because the previous file types uses
  the RAM while this one uses the disk, so use it if you need to create
  a temporary file bigger than 2 gigabytes.
  .
  For using the temporary file remember to use it like the following
  example:
  .
    log TEMPORARY_FILE 0 0      # reset it in case it already exists (optional)
    append                      # enables the append mode
    ...
        log TEMPORARY_FILE OFFSET SIZE
    ...
    append                      # disable the append mode
    open "." TEMPORARY_FILE 1   # open the temporary file on the file number 1
  .
  Note that from version 0.6.8, QuickBMS automatically overwrites this
  file if it already exists.


The following is the list of types of variables supported, also know as
datatypes or types.
The list is ordered just like in defs.h:

    BYTE            8 bit, 0 to 0xff

    SHORT           16 bit (aka INT), 0 to 0xffff

    THREEBYTE       24 bit, 0 to 0xffffff

    LONG            32 bit, 0 to 0xffffffff

    LONGLONG        fake 64 bit, so only 0 to 0xffffffff but Get takes 8 bytes

    STRING          null delimited string (one byte for each char)

    ASIZE           special type used to return the size of the opened file,
                    used only with the GET command 

    FILENAME        special type used to return the name of the opened file
                    like "myfile.zip", used only with the GET command

    BASENAME        special type used to return the base name of the opened
                    file like "myfile", used only with the GET command

    FILEPATH        the folder of the file, like "c:\path\folder" for
                    "c:\path\folder\file.txt"

    FULLBASENAME    just like FULLNAME without extension

    EXTENSION       special type used to return the extension of the opened
                    file like "zip", used only with the GET command

    UNICODE         special type used for unicode utf16 strings, the
                    endianess of the utf16 is the same used globally in the
                    script (watch the Endian command), it's used also for
                    converting an unicode string to an ascii one:
                      Set ASCII_STRING UNICODE UNICODE_STRING

                    unicode conversion is performed via Win32 API (CP_UTF8
                    and CP_ACP in case of 0xfffd chars) while on Linux it
                    uses iconv, fallback on mbtowc and byte=short

    BINARY          special type used for binary strings in C notation like
                    "\xff\x00\x12\x34", used mainly as a constant (cstring)

    LINE            special type used for carriage return/line feed delimited
                    string (so any string ending with a 0x00, 0x0a or 0x0d),
                    from version 0.6 the tool supports also strings that
                    have no delimiter at the end of file

    FULLNAME        full path of the file, in reality at the moment it returns
                    the same path used in the input filename

    CURRENT_FOLDER  the path from which has been launched QuickBMS

    FILE_FOLDER     the path of the loaded input file

    OUTPUT_FOLDER   the extraction folder (the last argument of QuickBMS)

    INPUT_FOLDER    same as above

    BMS_FOLDER  the folder where is located the bms script

    ALLOC           a type used only in the Set command for creating a variable
                    with a specific allocated size

    COMPRESSED      a special type used for setting big strings and memory
                    files using a small amount of text, for using this type
                    you must take the original text/file, compress it with
                    zlib (you can use my packzip tool) and then encoding the
                    output file with base64 (you can use my bde64 tool) and
                    placing the result like the following:
                      set MEMORY_FILE compressed eNrtwbEJACAMBMBecIfvnMUxPuEJAe0UHN81LLzrbYKwDOjI96IN1cLveRfAGqYu
                    this type is very useful if you want to embed a dll inside
                    a script without wasting much space

                    You can create this variable using the following script:
                      http://aluigi.org/bms/file_compressed_var.bms

    FLOAT           32 bit, 123.345 is read as 123

    DOUBLE          64 bit, 123.345 is read as 123

    LONGDOUBLE      96 bit, 123.345 is read as 123

    VARIABLE        read byte per byte till the byte is negative

    VARIABLE2       Unreal engine index numbers

    VARIANT         VB/C++ variant type (http://en.wikipedia.org/wiki/Variant_type)

    BITS            read a specific amount of bits, QuickBMS and the
                    language are byte based but the "bits" method works
                    very well

    TIME            time_t Unix 32bit time

    TIME64          64bit time used as FILETIME on Windows

    CLSID           ClassID like 00000000-0000-0001-0000-000000000000

    IPV4            7f 00 00 01 = "127.0.0.1"

    IPV6            like 2001:0db8:85a3:0000:0000:8a2e:0370:7334

    ASM             x86 assembly

    VARIABLE3       used in various software

    SIGNED_BYTE     0x99 is read as 0xffffff99

    SIGNED_SHORT    0x9999 is read as 0xffff9999

    SIGNED_THREEBYTE

    SIGNED_LONG     mainly useful in quickbms_4gb_files:
                    0x99999999 is read as 0xffffffff0x99999999

    VARIABLE4       used in Battlefield 3 (Frostbite engine)

    VARIABLE5       used in 7z archives

    UNKNOWN         use it to ask the user to insert the content of the variable

Just for the record, the original MexScript probably contained some
types of variables that have never been used and for which it's unknown
what they should represent: PURETEXT, PURENUMBER, TEXTORNUMBER and
FILENUMBER.

QuickBMS supports also the "experimental" multidimensional arrays
inside the variables, for example:

    for i = 0 < 10
        get VAR[i] long
        for j = 0 < 5
            get VAR2[i][j] long
        next j
    next i

But it's possible to access that variable ONLY by specifying the
original name and index, so:

    print "%VAR[0]%"    # fail!

    math i = 0
    print "%VAR[i]%"    # ok


The following is the list of bms commands:


.......................................................................

QuickBMSver VERSION

    Checks if the current version of QuickBMS is enough recent to
    support the script. It's used rarely, mainly for scripts created
    after the introduction of a new feature or an important fix.

    Arguments:
      VERSION   Oldest version of QuickBMS for which was created the script,
                it's just the version displayed at runtime by the tool.
                It's also possible to add some options that are suggested
                by the script to the user for enabling them at runtime,
                currently are supported:
                  -9  disable the safe memory allocator
                  -I  makes the variables case sensitive
                  -64 checks if the user is running quickbms_4gb_files.exe

    Examples:
      QuickBMSver 0.2.4
      QuickBMSver "0.5.14 -9"
      QuickBMSver "-I -9"

FindLoc VAR TYPE STRING [FILENUM] [ERR_VALUE] [END_OFF]

    It finds the first occurrence of a given string or number from the
    current offset of the archive, just by scanning it byte per byte.
    It's used in those cases when the format of the archive is not known
    or it's a particular text file.

    Arguments:
      VAR       The variable which will receive the offset of the occurrence
      TYPE      Type of the data we want to search, currently supported:
                - string and binary, they are handled as the same
                - unicode, the search will be performed as utf16 with the
                  data stored using the current endianess
                - numeric type (byte, short, long ...), you will search a
                  number stored using the current global endianess
      STRING    This value must be a number if TYPE is a numeric type,
                otherwise it must be a string in C notation (cstring)
      FILENUM   Number of the file associated to the archive (0)
      ERR_VALUE By default FindLoc terminates the script if no string
                is found but if ERR_VALUE is specified this value will
                be assigned to this value without terminating when there are
                no other occurrences, the best usage is ERR_VALUE set to ""
      END_OFF   Limit the scanning from the current offset till this
                offset, if END_OFF is minor than the current offset then
                the scanning will be backward

    Examples:
      For
          FindLoc OFFSET string "filename="
          ...
          FindLoc OFFSET string "filename=" 0 ""
          if OFFSET == ""
              cleanexit
          endif

          # scan backward
          goto 0 0 SEEK_END
          findloc OFFSET string "filename=" 0 "" 0
      Next


.......................................................................

For [VAR] [OP] [VALUE] [COND] [VAR]
...
Next [VAR] [OP] [VALUE]

    A classical "for" loop with initializers, conditions and
    incrementers.
    There is also the Break instruction available to break the loop at
    any moment but note that it's not suggested in presence of multiple
    For because in some rare cases it may not work correctly.
    "For" allows to perform an initial operation on a variable and to
    perform a check in each cycle to ensure a particular condition.
    "Next" is the command which delimits the loop and at the same time
    increments the given variable if specified.
    It's also possible to use a math operation in Next so that you can
    increment, decrement or perform any other operation at the end of
    each cycle.
    All the parameters are optionals and must be inserted in the
    specific order, so if there is no initialization you must use
    something like the following:
      For OFFSET = OFFSET < 1000
    For the record, there is also a "Prev" variant of the Next command,
    it performs the decrement of the variable.

    Arguments:
      VAR       Variable on which is performed the first math operation
                and is checked for the condition
      OP        Any of the available Math operators (check Math)
      VALUE     Value to assign to the variable or part of the math operation
      COND      Condition (check the If command)
      VAR       Second part of the condition

    Examples:
      For i = 0 < FILES
          ...
      next i
      For
         # do what you want here, this is an endless loop
      Next
      For VAR1 = VAR1 != VAR2
         # this is exactly the same of using while(VAR1 != VAR2) {...} in C
      Next VAR2 /= 3
      For OFFSET = OFFSET != ARCHIVE_SIZE
        ...
        Savepos OFFSET
        if OFFSET > 100
          break
        endif
      Next

Get VAR TYPE [FILENUM]

    It reads strings and numbers from the file, it's also the most used
    command.
    It supports many types of input and are the same already seen at the
    beginning of this section of the documentation like byte, short, long,
    string, unicode and so on.
    The tool automatically terminates when there is no data or partial
    data to read at the end of the file.

    Arguments:
      VAR       Variable which will receive the read data
      TYPE      Check the description of the types explained before
      FILENUM   Number of the file associated to the archive (0)

    Examples:
      Get OFFSET long
      Get NAME string


.......................................................................

GetDString VAR LENGTH [FILENUM]

    It reads a defined amount of data from the file and stores it in the
    given variable.
    It's useful with filenames and other strings that have a length
    specified in a previous 8, 16 or 32 bit field.

    Arguments:
      VAR       Variable which will receive the read data
      LENGTH    Amount of bytes to read.
                There is also an experimental method in which you can
                specify the elements and the size of each element like
                LENGTH*NUM, for example:
                  getdstring ARRAY NUMBERS*4
      FILENUM   Number of the file associated to the archive (0)

    Examples:
      GetDString NAME NAME_LENGTH
      GetDString NAME 0x100
      getdstring ARRAY ELEMENTS*4


.......................................................................

GoTo OFFSET [FILENUM] [TYPE]

    It changes the current position in the file, just like fseek in C.

    Arguments:
      OFFSET    Position to reach.
                The offset "SEEK_SET" is offset 0.
                The offset "SEEK_END" is the end of file.
                If it's a constant negative it will be considered
                the amount of bytes from the end of the file, so
                a negative variable is just considered as unsigned
                32bit.
                The offset depends also by the TYPE field.
      FILENUM   number of the file associated to the archive (0)
      TYPE      - SEEK_SET, the absolute offset (default)
                - SEEK_CUR, the relative offset from the current position
                - SEEK_END, the amount of bytes from the end, must be
                  negative or OFFSET will be converted to negative

    Examples:
      GoTo OFFSET
      GoTo 0x100
      GoTo -4           # 4 bytes before the end of the file
      GoTo SEEK_SET     # like goto 0
      Goto SEEK_END     # like goto 0 0 SEEK_END


.......................................................................

IDString [FILENUM] STRING

    It terminates the program if the magic/signature at the current
    position of the file differs than the provided string.
    If the string doesn't match and it's 4 bytes long QuickBMS will
    automatically swap it and perform the comparison again, if this time
    it matches then the endianess will be changed making most of the
    scripts written for an architecture (for example PC) virtually
    compatible with others (for example Xbox360).
    Pay attention to the FILENUM/VAR order different than other commands
    (it's a fault of the original BMS syntax), anyway QuickBMS will try
    to fix the order in case you invert them.

    Arguments
      FILENUM   number of the file associated to the archive (0)
      STRING    string in C notation (cstring)

    Examples:
      IDString "PK\x03\x04"
      IDString " KAP"
      IDString MEMORY_FILE "hello"
      IDString "hello" MEMORY_FILE  # it works too


.......................................................................

Log NAME OFFSET SIZE [FILENUM] [XSIZE]

    It extracts the file, this operation doesn't affect the current
    position of the input file.
    The content of the extracted file can be decrypted automatically
    using the Encryption command.
    If NAME is set to an empty string like "", QuickBMS will assign a
    sequential hexadecimal value and will try to guess the extension
    based on the content of the file.
    The extension will be automatically guesses and appended also to
    all the files that terminate with a dot or an asterisk like ".",
    "*" or ".*" or if they point to folders like "folder/".
    NAME can be also a special file like those that will be seen later,
    for example a socket, a process, an audio device and so on (in
    this case the user must have authorized the usage of the special
    files via command-line for using them).
    The filename will be automatically cleaned for dumping the file
    without problems.
    NAME can be also a MEMORY_FILE or a TEMPORARY_FILE.
    If a file with the same name already exists, QuickBMS will ask
    what action to take, the suggested one is the 'r' choice that
    will allow to automatically rename all the files with the same
    name without overwriting them.
    If you have used the Append command, the data will be appended to
    the existent file with the same name.
    Log and Clog share the same code, so the compression is the only
    difference.

    Arguments:
      NAME      Name of the output file
      OFFSET    Position in the archive where is located the file
      SIZE      Amount of the data to extract
      FILENUM   Number of the file associated to the archive (0)
      XSIZE     Used with block encryptions, this value is the aligned
                amount of data read from the disk, example for AES:
                   log NAME OFFSET 0x123      0 0x130
                  clog NAME OFFSET 0x123 SIZE 0 0x130

    Examples:
      Log NAME OFFSET SIZE
      Log "dump.dat" 0 SIZE
      Log "" 0 SIZE
      Log "folder/name.*" 0 SIZE


.......................................................................

Clog NAME OFFSET ZSIZE SIZE [FILENUM] [XSIZE]

    It extracts the file by decompressing it in real-time, this
    operation doesn't affect the current position of the input file.
    The decompression algorithm used in the operation is decided by the
    ComType command (zlib by default).
    The content of the extracted file can be decrypted automatically
    using the Encryption command.
    For additional information please refer to the Log command.

    Arguments:
      NAME      Name of the output file
      OFFSET    Position of the archive where is located the file
      ZSIZE     Size of the compressed data in the archive
      SIZE      Size of the uncompressed file, if you have specified
                a "_compress" algorithm you can use SIZE equal to ZSIZE
                because the tool will automatically calculate the
                maximum amount of bytes taken for the compression
      FILENUM   Number of the file associated to the archive (0)
      XSIZE     Used with block encryptions like AES, just like Log

    Examples:
      Clog NAME OFFSET ZSIZE SIZE
      Clog "dump.dat" 0 ZSIZE 10000000 # with some compression algorithms
                                       # the file will have the real size
                                       # while others will set it to 10000000

Math VAR OP VAR

    Mathematical operation between the two variables with the result
    placed in the first one.
    Note that due to compatibility all the operations are performed using
    signed 32 bit numbers by default.
    This makes the difference with some operation like the shift or the
    divisions, so pay attention!
    For unsigned operations add an 'u' before OP.
    The additional '=' you see in many scripts and in the examples is not
    needed, programmers are used to add it when the first variable is both
    input and output, like in C: var += 123;.

    Arguments
      VAR       Variable which acts as input and output
      OP        +   sum
                *   multiplication
                /   division
                -   substraction
                ^   xor
                &   and
                |   or
                %   modulus
                !   negation of var2 (0 becomes 1 and any other value becomes 0)
                ~   complement of var2 (like "xor 0xffffffff")
                <   shift left (also <<)
                >   shift right (also >>)
                l   rotate left (also <<<)
                r   rotate right (also >>>)
                s   byte swapping, 2 for reverseshort and 4 for reverselong
                w   bit swapping, reverse the amount of bits specified in var2
                =   assign var2 to var1
                n   negative value of var2 (like var1 = -var2)
                a   absolute value of var2 (-10 = 10 and 10 = 10)
                v   radix (also //)
                p   power (also **)
                x   alignment/padding, examples:
                    var1=0   var2=16  result=0
                    var1=1   var2=16  result=16
                    var1=16  var2=16  result=16
                    var1=17  var2=16  result=32
                y   round, like var1=(var1/var2)*var2, examples:
                    var1=0   var2=16  result=0
                    var1=1   var2=16  result=0
                    var1=16  var2=16  result=16
                    var1=17  var2=16  result=16
                z   common bitswapping (also <>):
                    var1=0xab    var2=4  result=0xba
                    var1=0xabcd  var2=4  result=0xdc
                    var1=0xabcd  var2=8  result=0xcdab
                reverselong     swap of 32bit variable
                reverseshort    swap of 16bit variable
                reverselonglong swap of 64bit variable
                binary  convert from binary to decimal
                octal   convert from octal to decimal
                hex     convert from hexadecimal to decimal (this is automatic,
                        use it only if VAR2 doesn't have a 0x prefix)
                base*   convert from base* to decimal, so base8 is octal, base2
                        is binary, base16 is hex and so on
                Add a 'u' before or after OP for forcing the usage of unsigned
                operations useful with shift, divisions and possibly other
                operations.
                Any operation starting with a '?' will be considered a
                verbose operator, for example ?add is the same of +.
                QuickBMS supports also all the functions available in
                math.h like ?sin, ?cos, ?atan and so on. Unfortunately it's not
                possible to list them here, please check math_operations() and
                old_set_math_operator() in cmd.c.
      VAR       Other input variable

    Examples:
      Math SIZE * 0x100
      Math OFFSET << 2
      Math OFFSET u<< 2
      Math TMP = SIZE
      Math TMP ~ TMP
      Math TMP n TMP
      Math TMP2 a TMP
      Math SIZE u/ 5
      Math RADIX v 2

XMath VAR INSTR

    Multiple mathematical operations in one line, just a way to avoid
    the limitations of the original Math command.
    Currently this command is just an experiment and supports only the
    most simple operators named with a non-alphanumeric character and
    applied to unsigned numbers:
        ~ ! < > & ^ | * / % - +
        <<< shift left
        >>> shift right
        **  power
        //  root
        &&  alignment
        <>  common bit swapping
        %%  percentage ("VAR %% 15" will return the 15% of VAR)
    This command is directly derived from my calcc tool:
      http://aluigi.org/mytoolz.htm#calcc
    Please note that XMath is a lot slower than Math.
    Do NOT use the unsigned labels or the additional '=' you use with the
    Math command because they are NOT supported since all operations
    are unsigned in XMath, so:
      xmath TMP "TMP u<<= 5"    is WRONG
      xmath TMP "TMP << 5"      is CORRECT

    Arguments
      VAR       Variable that acts as output
      INSTR     The full instruction

    Examples:
        XMath VAR "1 + 2 - ((3 + 4) + VAR * VAR2)"

Open FOLDER NAME [FILENUM] [EXISTS]

    It opens a file, basically it assigns a file number/id to an existent
    file that you want to use.
    If NAME is '?':
    - and FOLDER is FDDE the user must type the extension of the file to load,
      the name is the same of the one currently open
    - and FOLDER is FDSE the user must type the name of the file loaded from
      the same folder
    - the user must type the full name of the file to load

    Arguments:
      FOLDER    FDDE, means that you want to open the file in the same
                  location of the input one which has the extension
                  provided with NAME, so FDDE is for the extension only
                FDSE, it will consider NAME as a file located in the
                  same folder of the input file (very useful)
                any other value is considered the folder where is located
                  the file to load so use "." for the current output
                  folder
      NAME      Read above, NAME can be also a ? in which case QuickBMS
                will ask the user to insert the name of the file to open
                manually
                if NAME is "" then will be performed a flush operation
                that could be useful (or not?) only in write mode (debug)
      FILENUM   Number of the file associated to the archive (0)
      EXISTS    If the file doesn't exist this variable will be set to
                0 or 1 if it exists. by default QuickBMS terminates
                with an error if the file doesn't exist.

    Examples:
      Open FDDE DAT 0
      Open FDDE IDX 1
      Open FDSE "myfile.zip"
      Open "." TEMPORARY_FILE 1


.......................................................................

SavePos VAR [FILENUM]

    Current position of the file, like ftell in C.

    Arguments:
      VAR       Variable which will contain the offset
      FILENUM   Number of the file associated to the archive (0)

    Examples:
      SavePos OFFSET


.......................................................................

Set VAR [TYPE] VAR

    Command for assigning a constant or a variable to another variable
    with the possibility of changing its type, utf8 to unicode and vice
    versa.

    Arguments:
      VAR       Output variable or memory file
      TYPE      In general the type is not much important because in
                QuickBMS there is almost no difference between numbers
                and strings, anyway the following are the special types:
                - unicode, unicode to utf8, endian dependent
                    set NAME unicode NAME
                - to_unicode, utf8 to unicode, endian dependent
                    set NAME to_unicode NAME
                - binary, C notation (cstring)
                    set MEMORY_FILE binary "\x11\x22\x00hello"
                - alloc: allocates memory, something like putvarchr VAR SIZE 0
                    set VAR alloc 0x1234
                - filename: takes the filename part from a string (myfile.txt)
                    set NAME filename "c:\folder\myfile.txt"
                - basename: takes the basename part from a string (myfile)
                - extension: takes the extension part from a string (txt)
                - unknown: the user is asked to insert the content of the variable
                    set VAR ? ?
                - strlen: just a wrapper for the Strlen command
                    set NAMESZ strlen NAME
      VAR       Variable or constant to assign

    Examples:
      Set i long 0
      Set TMP long SIZE
      Set TMPNAME NAME
      Set MEMORY_FILE binary "\x12\x34\x56\x78"
      Set ASCII_VAR unicode UNICODE_VAR # from unicode to string
      Set VAR ? ?   # the user will be prompted to insert his content


.......................................................................

Do
...
While VAR COND VAR

    A not so useful type of cycle where the check of the condition is
    performed at the end of the cycle... really rarely used.
    If you need a C-like "while(...) {...}" use the For command.

    Arguments:
      VAR       first part of the condition
      COND      condition, check the If command below for additional info
      VAR       second part of the condition

    Examples:
      Do
          ...
      While OFFSET < MAX_OFFSET


.......................................................................

String VAR OP VAR

    The equivalent of the Math command for the strings.
    The first variable can be an input and output or only an output
    depending by the operator.
    You can use also a textual OP, this value is the one in the first
    line of the operator you see below (for example "equal" is '=').
    The string searching operators are quite confusing because the tool
    didn't have this feature and they were implemented in the String
    command later as experimental features.

    Arguments:
      VAR       Input and output variable
      OP        =   equal, copy
                    just a copy, but if var2 is a number it will be
                    considered a raw string, very useful for Long to
                    String conversions:
                      var2="0x44434241", result="ABCD"
                +   append, add
                    append the second string to the first one
                -   truncate, remove
                    if the second variable is a positive number the
                      string will be truncated at that amount of bytes
                      from the end: var1[len1 - num] = 0;
                    if the second variable is a negative number the
                      string will be truncated at that amount of bytes
                      from the beginning: var1[num] = 0;
                    otherwise will be removed all the occurrences of
                    the second string in the variable
                ^   xor
                    xor the first string with the second one (looped if shorter)
                <   shl, shift_left
                    like strrchr/strrstr returning the part before it plus
                    the searched string:
                      var1="thisisastring", var2="is", result="thisis"
                    instead if it's a number will move the string of those
                    positions:
                      var1="thisisastring", var2="4",  result="isastring"
                      var1="thisisastring", var2="-4", result="ring"
                *   mul, replicate
                    replicate the string for the number of times specified by the
                    second variable
                      var1="hello", var2=5, result:"hellohellohellohellohello"
                    if it's a string it acts as strchr/strstr returning the part
                    before it plus the searched string:
                      var1="thisisastring", var2="is", result="this"
                %   mod
                    if the second variable is a positive number
                      cut the variable at the position obtained by the modulus
                      of its length and the number in the second variable
                    while if it'a string it acts like strchr/strstr returning
                    the data before the result
                      var1="thisisastring", var2="is", result="th"
                &   strchr, strstr
                    first occurrence
                      var1="thisisastring", var2="isa", result="isastring"
                |   strchrx, strstrx
                    first occurrence + var2 length
                      var1="thisisastring", var2="isa", result="string"
                $   strrchr, strrstr
                    last occurrence plus searched string
                      var1="thisisastring", var2="isa", result="isastring"
                !   strrchrx, strrstrx
                    last occurrence + var2 length
                      var1="thisisastring", var2="isa", result="string"
                >   shr, shift_right
                    if the second variable is a number:
                      var1="thisisastring", var2="4", result="thisisast"
                    otherwise the string is searched from the END of the variable
                    just like strrchr/strrstr returning the part before
                    the searched string:
                      var1="thisisastring", var2="isa", result="this"
                r   reverse
                    reversed string, "abcd" -> "dcba"
                b   byte2hex
                    byte2hex of var2: var2="abc", result="616263"
                B   byte2hex_string
                    as above but uses the var2 as a null delimited string (strlen)
                h   hex2byte
                    hex2byte of var2: var2="616263", result="abc"
                e   encrypt, encryption
                    experimental encryption based on the Encryption command
                E   encrypt_string
                    as above but uses var2 as a null delimited string (strlen)
                c   compress, compression, comtype
                    experimental compression based on the ComType command
                C   compress_string
                    as above but uses var2 as a null delimited string (strlen)
                u   toupper
                    var2="hello", result="HELLO"
                l   tolower
                    var2="HELLO", result="hello"
                R   replace
                    replace chars: var1="helloworld", var2="world", var3="me", result="hellome"
                p   printf, sprintf
                    a printf-like experimental work-around
                    the format for float (f) and double (g) works only
                    for one element, so:
                      get VAR_LONG long
                      String TMP p "%10.10f" VAR_LONG # no VAR2 or VAR3
                      print "%TMP%"
                P   QuickBMS Print
                    same output of the Print command, for example:
                      string VAR P "hello %VAR1% test %VAR2|x%"
                s   sscanf
                    a sscanf-like experimental work-around, only for numeric 32bit values
                      string "123:456" s "%d:%d" VAR1 VAR2
                S   split
                    it's like a sscanf for strings, both ' and " are handled as
                    quotes.
                    string ELEMENTS S "string1 \"string 2\" 'string3'" VAR1 VAR2 VAR3
                x   cstring
                    convert a C string (cstring) to the relative string/binary
                      string VAR x \x78\x7a
                f   filter
                    filter the non alphanumeric chars by replacing them with '_'
                m   math, xmath
                    math and xmath operation just like those in the Encryption command
                    so #INPUT#+1 means that 0x01 will be added to each char of VAR
                    quick example:  string VAR m "#INPUT#+1"    # xmath if there is INPUT
                                    string VAR m "+ 1"          # math
                w   hex2uri
                    var2="%2fhello", result="/hello"
                W   uri2hex
                    var2="hello<>", result="hello%3c%3e"
                t   very basic html/xml tags remover, de_html
                T   html/xml formatter, one tag or text per line, easy_html
                Use an additional zero ("0") to return "" in case of errors like when
                the operators that search strings can't find the pattern (in which case
                will be returned the original string by default), this is very useful
                while playing with strings, for example
                "string VAR1 0strchr VAR2" will return "" if VAR2 is not found in VAR1
                (instead of leaving VAR1 unchanged), another example: String VAR1 0$ VAR2
      VAR       The second variable or string

    Examples:
      string FULLPATH + NAME
      string FULLPATH + \
      string NAME - ".zip"
      string NAME - 4
      string PATH R "." "/"
      string FULLPATH p "c:\folder\%04x%04x.dat" VAR1 VAR2     # VAR1/2 are the input
      string FULLPATH s "c:\folder\%04x%04x.dat" VAR1 VAR2     # VAR1/2 are the output

If VAR COND VAR [...]
...
[Elif VAR COND VAR]
...
[Else]
...
EndIf

    It checks various conditions and performs the needed operation when
    the condition is verified, in short:
    - If is ever the first condition
    - Elif is another condition and can be used endless times
    - Else is the operation to do when no conditions are met, the last one
    - EndIf delimits the If command statement
    It's also possible to use multiple conditions (max 3 or 4) like:
      if VAR1 < VAR2 && VAR3 > VAR4
      elif VAR1 != 0 || VAR2 != 0
    The 'u' added before the condition forces an unsigned comparison
    with numbers and a case sensitive comparison with strings.
    The condition is considered for both strings and numbers, for more
    technical details it's necessary to check the check_condition()
    function in the cmd.c source code.

    Arguments:
      VAR       First part of the condition
      COND      Valid for both strings and numbers:
                <   minor, lower, below
                >   major, greater, above
                !=  different, <> !==
                ==  equal, = === strcmp stricmp strcasecmp
                >=  major/equal
                <=  minor/equal
                &   string: var2 is included in var1 (strstr)
                    number: logical AND
                ^   string: equal
                    number: logical XOR
                |   number: logical OR
                %   number: modulus
                /   number: division
                <<  number: shift left
                >>  number: shift right
                !   number: negation, not
                !!  number: true, use it to know if VAR is non-zero
                ~   number: complement
                strncmp     if "mystring" strncmp "myst"
                ext compares the string after the last dot
                basename    compares the string before the last dot
                filepath    compares the part before the filenames, you
                            can force a folder without filename by appending
                            a slash: "c:\folder/" instead of "c:\folder" (that will be "c:")
                any other operation supported by the Math command (valid
                  only for the numeric variables)
                add a 'u' before COND for forcing the usage of unsigned
                operations useful with shift, divisions and possibly other
                operations, if the variables are strings then it will
                perform an case sensitive comparison instead of the default
                insensitive one
      VAR       Second part of the condition

    Examples:
      If NAME != ""
          ...
      Endif
      If MASK & 1
      Elif MASK & 2
      Elif MASK & 4
      Elif MASK & 8
      Else
      Endif

GetCT VAR TYPE CHAR [FILENUM]

    It reads a string till the reaching of the CHAR delimiter.

    arguments
      VAR       Output variable
      TYPE      Only unicode is the alternative type, any other value
                is just ignored because doesn't matter for this
                operation
      CHAR      The delimiter character as 8bit number, if this number
                is negative QuickBMS will convert it to positive and
                read till the current byte is the same (so it's like
                a way to skip the same byte in a file)
      FILENUM   Number of the file associated to the archive (0)

    Examples:
      GetCT NAME string 0x0a
      GetCT NAME string 0x3b
      set DELIMITER_BYTE long 0x0a

ComType ALGO [DICT] [DICT_SIZE]

    It selects a specific compression algorithm to use with the Clog
    command.
    It's also possible to choose a number as ALGO, this is a feature
    coming from my project for a compression scanner able to guess
    the possible algorithm of an unknown compressed data block:
      http://aluigi.org/bms/comtype_scan2.bat
      http://aluigi.org/bms/comtype_scan2.bms
      comtype_scan2.bat comtype_scan2.bms input_file output_folder
      comtype_scan2.bat comtype_scan2.bms input_file output_folder uncompressed_size
    Note that some algorithms may work only on Windows.
    if ALGO is "?", the user is prompted to type the desired algorithm.

    Arguments:
      ALGO      copy, simple copy that useful in some rare cases with
                  data encrypted with block ciphers like AES and blowfish
                  so use comtype copy and encryption
                zlib, RFC1950 (aka windowbit 15, the data starts with a 'x')
                  DICT supported
                  if DICT starts with "Z_FULL_FLUSH" inflate/deflate will use Z_FULL_FLUSH
                deflate, RFC1951 (aka windowbit -15) used for example in the ZIP files
                  DICT supported
                  if DICT starts with "Z_FULL_FLUSH" inflate/deflate will use Z_FULL_FLUSH
                lzo1a till lzo2a, LZO (remember that the most used is lzo1x)
                  DICT supported
                lzss, with default configuration (dictionary of 4096 bytes)
                  this particular algorithm can be fully configured setting the
                  EI, EJ and P fields plus another number rarely used:
                    EI, EJ, P, rless, init_chr
                  for setting them it's enough to use a DICT equal to something
                  like "12 4 2" which means EI:12 (N:4096), EJ:4 (F:18), P:2
                  use a negative init_chr for different window slide customizations
                  like -1 for Tales of Vesperia
                  the default character of lzss is a space (0x20), but you can use the
                  ALGO lzss0 or the dictionary "12 4 2 2 0" to use 0x00
                lzx, used by the old (aka jurassic) unlzx tool and on Amiga
                gzip, automatic handling of the gzip data
                  remember that in this case the uncompressed size is
                  ignored and calculated automatically so in CLog use
                  ZSIZE ZSIZE
                pkware, the algorithm also known as blast/explode/implode/DCL
                lzma, 5 bytes + lzma (in some cases you may need to use ZSIZE + 5)
                lzma86head, 5 bytes + 8 bytes (size) + lzma
                lzma86dec, 1 byte + 5 bytes + lzma (in some cases you may need to use ZSIZE + 5)
                lzma86dechead, 1 byte + 5 bytes + 8 bytes (size) + lzma
                lzmaefs, the format implemented in ZIP
                bzip2
                XMemDecompress, (aka xmemlzx) Xbox 360 LZX algorithm of xcompress.lib
                  use DICT to specify a custom WindowSize and CompressionPartitionSize
                  like "131072 524288"
                  the algorithm automatically idenfities and extracts the LZXTDECODE
                  and LZXNATIVE files generated by xbcompress.exe (0x0FF512ED / 0x0FF512EE)
                hex, from "01234567" to 4 bytes: 0x01 0x23 0x45 0x67
                base64, from "aGVsbG8=" to "hello", supports also the Gamespy

                base32nintendo
                base???, if ALGO starts with "base" then will be taken its
                  subsequent number (for example 32 if it's "base32") and
                  used for the conversion. the function supports ANY base
                  conversion from 2 to 256.
                  for bases larger than 64 will be used a char table starting
                  from byte 0x00 so base128 will have a charset from 0 to 0x7f

                  so, even if it uncompress the data, it may be invalid.
                  use zlib_noerror if you are 100% sure that the input is zlib or
                  non compressed, and deflate_noerror for deflate
                zlib_noerror, as zlib but doesn't quit in case of errors and

                  any supported flag, so it should blindly work against any
                  compressed lzma input.
                  if it's not compressed, the input will be copied on the output.
                  another difference with "lzma" is that lzma returns an error
                  if the input buffer doesn't have other compressed bytes
                  (LZMA_STATUS_NEEDS_MORE_INPUT) while lzma_dynamic gives the ok,
                  this is useful with some rare cases like Far Cry 3 (fat2_fat3.bms)

                MRLE_COMPRESS
                CPK_COMPRESS, note that in reimport mode it may not work
                    because the decompression is size-dependent so the
                    compressed size will probably change but the value
                    will not be modified in the original archive (the
                    reimport mode changes only the data of the files).
                    if you want it to work you have to manually edit the
                    value from the archive, launch quickbms -V and search
                    something like the following:
                        . 00000eef get     value      0x0000e548 4
                        . 00000023 get     column_name "FileSize" -1
                    in that example you have to set the new value at
                    offset 0xeef, but note that the new compressed size
                    is not displayed by quickbms... yeah not easy

                    that is used to find the algorithm when using my
                    compressions scanner

    DICT        an optional C string containing the bytes of the dictionary
                (cstring) or particular parameters depending by the chosen
                algorithm.
                Note that DICT can be:
                - a cstring
                  comtype algo "\x11\x22\x33"     // static binary dictionary
                - a variable for which, often, you must specify also a length
                  comtype algo DICT DICT_SIZE     // variable dictionary

ReverseShort VAR

    Classical swap that inverts a 16bit variable from 0x2211 to 0x1122
    and vice versa.

    Arguments:
      VAR       variable to flip


.......................................................................

ReverseLong VAR

    Classical swap that inverts a 32bit variable from 0x44332211 to
    0x11223344 and vice versa.

    Arguments:
      VAR       variable to flip


.......................................................................

ReverseLongLong VAR

    Classical swap that inverts a 32bit variable from 0x8877665544332211
    to 0x1122334455667788 and vice versa.
    This command works only with quickbms_4gb_files.exe

    Arguments:
      VAR       variable to flip


.......................................................................

Endian TYPE [VAR]

    It changes the current global endianess of the read/written data,
    the default one is little endian.

    Arguments:
      TYPE      - little, intel
                  endianess where 0x11223344 is stored as 44 33 22 11
                - big, network
                  endianess where 0x11223344 is stored as 11 22 33 44
                - swap, change, invert
                  change endianess, if it was big now will be little
                - guess
                  followed by a 32bit number. The function swaps the number
                    and compares it with the original one so if the number
                    is 0x04000000 then the swapped one will be 0x4 and the
                    tool will change the global endianess and the one of
                    the variable
                - guess16
                  followed by a 16bit number
                - guess64
                  followed by a 64bit number
                - guess24
                  followed by a 24bit number
                - save, store
                  stores the current endian in VAR: 1 for big and 0 for little

    Examples:
      print "little endian"
      endian big
      print "big endian"
      endian little
      print "little endian"
      endian change
      print "little->big endian"
      endian guess 0x04000000
      print "guess endian"
      endian save CURRENT_ENDIAN
      if CURRENT_ENDIAN == 0
        print "little endian"
      else
        print "big endian"
      endif

FileXOR SEQ [OFFSET]

    Any read operation (Get, *Log and so on) on any file will perform
    also the xoring of the read data with the numbers contained in the
    given string or in the given variable.
    The OFFSET field by default is zero which means that if the data
    must be xored with more than one byte (a "xor key") the first byte
    of the key is the first byte at OFFSET which is 0 by default
    (beginning of the file).
    Recap: the FileXOR command works with ANY file access.

    Arguments:
      SEQ       Sequence of space-separated 8bit numbers, it can be a:
                - sequence of bytes separated by space like 0x12 or
                  "0x12 0x34 0x56" or directly a C hex string like
                  "\x12\x34\x56" (NOT a C notation!)
                - a numeric variable like MYXORKEY
                - a string that doesn't start with numbers, '\' or '-'
                Currently it's not possible to use a key in string mode
                and use the Encryption command for doing it, so if you
                have a string convert it to a numeric sequence first or
                be sure that it doesn't start with the chars shown above.
                Set it to 0 or "" for disabling the xor
                Note that SEQ can be also a 32bit signed number like
                filexor 0x11223344 but the size is decided by value so
                0x00000022 is 8 bit and not 32, while -0x20 is considered
                8bit and 0x80112233 a 32bit.
      OFFSET    Needed only for the xor key offset.
                If the archive is xored with a xor key from its beginning
                  (so first byte of the archive xored with the first one
                  of the key) this argument is usually not necessary
                Instead if only the file to extract is xored, this
                  argument must have the same offset of the file (so
                  just reuse the same OFFSET used in Log)

    Examples:
      filexor 0xff
      filexor -0x20
      filexor 0x1122    # 32bit
      filexor -0x1122   # 32bit
      filexor "0x12 0x34 123 255"
      filexor MYXORBYTE
      saepos OFFSET
      filexor "0x12 0x34 123 255" OFFSET
      filexor "\x12\x34\x7b\xff"
      Log NAME OFFSET SIZE


.......................................................................

FileRot SEQ [OFFSET]

    Exactly as for FileXOR but it performs a sum operation.
    For example if SEQ is 0x01 and the file contains "hello" it will
    become "ifmmp" while if SEQ is -1 or 0xff it will become "gdkkn".
    -1 and 0xff are the same because it's a 8 bit number while
    0x100 or -0x100 are considered 32bit.
    Recap: the FileRot command works with ANY file access

    Watch the previous arguments and examples.


.......................................................................

FileCrypt SEQ [OFFSET]

    Experimental, it works only if has been already specified and
    enabled the Encryption command and basically applies those
    algorithms to the normal file reading operations.
    Note that at the moment OFFSET is unused and SEQ can be only 1 for
    activating it and "" to disable it ("" and NOT 0!).
    Remember that the encryption algorithms usually work on blocks of
    data so this command is probably useless.

    Full example:
      get NAMESZ long
      encryption xor "\x11\x22\x33\x44"
      filecrypt 1
      getdstring NAME NAMESZ
      filecrypt ""
      encryption "" ""


.......................................................................

Strlen VAR VAR [SIZE]

    It calculates the length of the second variable (as string) and
    stores it in the first one.
    The length is the amount of consecutive non-zero bytes, so it
    doesn't work with unicode strings except if, maybe, SIZE is set.
    Note that for practical reasons this command can be emulated also
    using "set VAR strlen VAR".

    arguments
      VAR       Destination variable which will contain the length
      VAR       Variable of which calculating the length
      SIZE      set it to 1 to receive the size of the variable instead
                of its NULL delimited lenght, may be useful in some
                situations where you need to ignore the 0x00 bytes

    examples
      strlen NAME_LENGTH NAME
      strlen NAMESZ NAME
      strlen RAW_NAMESZ NAME 1


.......................................................................

GetVarChr VAR VAR OFFSET [TYPE]

    A particular and sometimes very useful command which works exactly
    like accessing an array of elements contained in the second variable,
    for example a string or a memory file.
    It can be compared to C as: var1 = var2[offset];
    This simple and effective method allows the manipulation of strings
    and variables for creating custom headers (like a DDS) and moreover
    for performing operations on a piece of the memory, like a custom
    encryption algorithm.
    Some real examples are my Deer Hunter 2004/2005 scripts.

    Arguments:
      VAR       Destination variable which will contain the read element
      VAR       Variable or memory file from which you want to get the
                element
      OFFSET    Position of the second variable where taking the element
      TYPE      Type of the element to read and assign to the first
                variable, if not specified it's a BYTE so a 8bit number.
                You can specify most of the available datatypes like
                short, long, longlong and so on

    Examples:
      For i = 0 < SIZE
          GetVarChr TMP MEMORY_FILE i
          GetVarChr TMP MEMORY_FILE i long
          # GetVarChr TMP MEMORY_FILE i string
      Next i


.......................................................................

PutVarChr VAR OFFSET VAR [TYPE]

    The "write-mode" alternative of the previous command which allows
    to perform various complex operations with custom algorithms (like
    in my Deer Hunter 2004/2005 scripts).
    It can be compared to C as: var1[offset] = var2;
    Note that PutVarChr can be also used as an allocator of memory that
    is often useful in the implementation of custom decompression
    algorithms or, moreover, for pre-allocating a MEMORY_FILE for
    storing chunks. This is useful to avoid wasting time and memory
    with the incremental allocation, remember only to use the command
    "Log MEMORY_FILE 0 0" after it for resetting the position of the
    MEMORY_FILE.

    arguments
      VAR       Variable or memory file in which you want to put the
                element
      OFFSET    Position of the output where placing the element, it can
                be also negative in which case it will work from the end
                of the variable (may not work in some conditions)
      VAR       Source variable which will contain the element to write
      TYPE      Type of the element to read and assign to the first
                variable, if not specified it's a BYTE so a 8bit number.
                You can specify most of the available datatypes like
                short, long, longlong and so on.

    Examples:
      For i = 0 < SIZE
          GetVarChr TMP MEMORY_FILE i
          Math TMP ^= 0xff
          PutVarChr MEMORY_FILE i TMP
      Next i

Debug [MODE]

    Switch command that enables the -v option in real-time for a
    specific portion of the script, used only for debugging.

    If MODE is specified and it's a positive number, QuickBMS will only
    display the content of the variables read/written with the Get/Put
    commands. This is very useful and cool for debugging file formats
    and protocols in an easy way just like -V.

    If MODE is negative, it will disable the verbose mode.

    Examples:
      debug     # like -v
      debug 0   # like -v
      debug 1   # like -V
      debug -1  # disable -v/V


.......................................................................

Padding VAR [FILENUM] [BASE_OFF]

    When called it performs an automatic GoTo to the next position of
    the file skipping the aligned data.
    Imagine to have a file where it's used an alignment of 4 bytes and
    your current file offset is 0x39, if you use Padding 4 the offset
    will be automatically changed to 0x3c.
    By default the padding is referred to the beginning of the file
    (offset 0).

    Arguments:
      VAR       Size of the alignment, for example 4 or 16 and so on
      FILENUM   Number of the file associated to the archive (0)
      BASE_OFF  base offset from which must be calculated the padding (0)

    Examples:
      Get NAME string
      Padding 4
      get OFFSET long

Append [DIRECTION]

    Command to enable the append mode in the *Log commands, so if the
    output filename already exists it will not be overwritten, the new
    content will be concatenated (appended) to the existent one.
    Note that with real files (not memory files) the user may be prompted
    before writing the output file if it already existed before the
    running of the script.
    Note that the reimport mode may not work correctly when you use a
    combo of MEMORY_FILE and Append (like I usually do in my scripts),
    so the direct and more simple Log to file + Append is suggested.

    Arguments:
      DIRECTION This is a new optional argument that allows to specify
                where placing the new content:
                -1  a negative value means that the new content will be
                    placed before the current file, so the old content
                    will be appended to the new one
                0   the new content will be appended to the current one
                    (default, just like without DIRECTION)
                1   the new content will overwrite the current one without
                    changing the file size if the new one is smaller, use
                    goto to set the offset where placing the new content

    Examples:
      append
      Log "dump.dat" 0 0x10
      Log "dump.dat" 0x10 0x100

    The following is a particular example for allocating a MEMORY_FILE
    and using it instead of TEMPORARY_FILE saving space on the disk and
    performances:
      math TMP = CHUNKS
      math TMP *= 0x8000
      log MEMORY_FILE 0 0
      putvarchr MEMORY_FILE TMP 0   # improves the speed with pre-allocation
      log MEMORY_FILE 0 0           # reset the position and size of the file
      append
      for i = 0 < CHUNKS
          ...
          clog MEMORY_FILE OFFSET ZSIZE 0x8000
      next i
      append
      get SIZE asize MEMORY_FILE

Encryption ALGO KEY [IVEC] [MODE] [KEYLEN]

    One of the most interesting commands which allows to set a
    decryption algorithm used for the Log and CLog command.
    QuickBMS supports also the hashing algorithms of OpenSSL, the
    binary hash will be placed in the variable QUICKBMS_HASH while the
    hexadecimal hash in QUICKBMS_HEXHASH (capital letters) and
    QUICKBMS_HEXHASHL (low).
    Note that the hashing algorithms don't need a key, but you can use
    that field for performing a direct hash operation on the provided
    key without using the log command, eg: encryption sha1 "mystring".
    You can also specify the size in case it's a binary variable, eg:
    encryption md5 "mystring" "" 0 8.
    For the HMAC hash algorithm you must use the IVEC field, anyway
    remember that this feature is just optional.

    Arguments:
      ALGO      aes, Rijndael
                blowfish, you should try also bf_ecb if the result is
                  not the expected one

                xtea, use IVEC to specify custom delta, endian (0/1), cycles and if_invert_delta_operation
                xxtea, use IVEC to specify custom delta, endian (0/1), cycles and if_invert_delta_operation
                idea
                swap, use the bytes to swap as key, it works just like
                  reverseshort and reverselong: encryption swap 2: 2211 -> 1122
                reverseshort, swap 2
                reverselong, swap 4
                math, exactly like the bms command plus the size of the numbers:
                    encryption math "^u= 0x11223344 1" 32
                    encryption math "n #INPUT#"             # decrypted = -encrypted
                  it means that this encryption can do tons of operations
                  including xor, rot, rotate and so on.
                  the "1" after the math operation means if we want to
                  respect the exact size of each element like a sort of
                  AND SIZE (default ignore).
                  ivec is the size of each element (8 bits default)
                xmath, key is the operation to perform for each element
                  ivec is the size of each element (8 bits default)
                  use #INPUT# to identify the element read from the data:
                    encryption xmath "((#INPUT# + 1) << 2) + #INPUT#" 8
                random, pseudo random incrementer (Linear congruential
                  generator) xored with the input key contains a number
                  corresponding to the algorithms listed on
                  http://en.wikipedia.org/wiki/Linear%5Fcongruential%5Fgenerator#Parameters_in_common_use
                  (0 is the first one) plus other algorithms like
                  mersenne and so on.
                  the second parameter in the key is the seed.
                  the third one is the mask of bits of the key to use for
                  the operation.
                  ivec is the size of each element (8 bits default).
                    encryption random "0 0x12345678"
                    encryption random "0 0x12345678" 32         # 32bit values
                    encryption random "0 0x12345678 0x7fff0000" # value ^ ((key >> 16) & 0x7fff)
                  you must check the src\myenc.c source code to have the full list
                xor
                rot
                rotate, an 8/16/32/64bit ror or any other bit as key, element size as ivec
                reverse, flip the file from the end to the beginning
                incremental,
                  encryption "incremental xor" 0 0x01           # 8bit xor incremented by 1 each time
                  encryption "incremental rot" 0x100 0x11223344 # 32bit rot starting from 0x100 incremented
                                                                # by 0x11223344 each time
                charset, the substitution algorithm which uses a charset of 256 chars
                charset2, as above but the substitution is inverted, very useful
                twofish

                icecrypt, ICE algorithm with key implemented as in the
                  homonym program, the difference with "ice" is ONLY in
                  the key
                rotor, added as experiment, ivec contains the number of
                  rotors (12)
                ssc, Leverage SSC
                wincrypt, aka cryptdecrypt or cryptencrypt
                  use the ivec field to specify the following fields
                  (only those you need, not all are necessary):
                  - the hashing algorithm - CryptCreateHash, you can find the key here
                  - the encryption algorithm - CryptDeriveKey
                  - the provider type - CryptAcquireContext
                  - Microsoft provider name, like MS_DEF_DH_SCHANNEL_PROV
                  - CryptDeriveKey flags, like CRYPT_CREATE_SALT
                  - CryptDecrypt flags, like CRYPT_OAEP
                  example:
                    encryption CryptDecrypt "mykey" "CALG_MD5 CALG_RC4 PROV_RSA_FULL"
                    encryption CryptDecrypt "1111" "CALG_MD5 CALG_RC4 PROV_RSA_FULL CRYPT_CREATE_SALT CRYPT_OAEP"
                cryptunprotect, key is used to specify the entropy so the default is ""
                zipcrypto, the first 12 bytes are the encryption header
                  set the ivec to 1 for automatically cutting the first 12 bytes

                crc, a complete and powerful checksum function that can
                  be fully configured:
                  - key is the polynomial (use "" for the default crc32 0x77073096)
                  - ivec contains:
                    - the size of the crc (8/16/32)
                    - the initial value (like -1)
                    - the final xor value (-1, the complement)
                    - the type (various supported)
                    - the reverse mode during the generation of the table
                    - the bitmask_side (0 or 1 where 1 is the most used one)
                  default values: 0xedb88320 32 -1 -1 0 0 1
                  if you need the classical crc16 (0xc0c1) use:
                    encryption crc 0xa001 "16 0 0 0 0 1"
                  or
                    encryption crc "" 16
                  the result is placed in the variable QUICKBMS_CRC
                  for additional info:
                    http://aluigi.org/bms/quickbms_crc_engine.txt
                  for technical information about the operations check the
                  crc_calc function in crc.c, it's quite easy to understand
                  because it contains the simple operations performed in
                  each cycle.
                  note that some crc types use the polynomial value as
                  constant in each cycle
                EXECUTE:
                  use KEY to specify the command to execute using #INPUT#
                  instead of the input filename and #OUTPUT# for the output
                  one, you can also specify a variable by using the %VAR%
                  notation.
                  IMPORTANT NOTE: do NOT use "encryption execute" if the
                  output will be bigger than the input, use Clog in that case!
                  example:
                    encryption EXECUTE "mycrypt.exe d #INPUT# #OUTPUT#"
                  another full example:
                    get SIZE asize
                    encryption EXECUTE "lame.exe -V 4 #INPUT# #OUTPUT#"
                    log "newfile.mp3" 0 SIZE
                    encryption EXECUTE "otherprog.exe #INPUT# #OUTPUT# %SIZE%"
                    log "newfile2.mp3" 0 SIZE
                CALLDLL:
                  exactly as above except that the variables don't need to be
                  specified within '%' because calldll already handles them,
                  but don't worry because even if you do that the result
                  should not change, experimental:
                    encryption calldll "test.dll myfunction cdecl RET #INPUT# #INPUT_SIZE# MYVAR"
                    get SIZE asize
                    log "newfile.mp3" 0 SIZE
                "" "", disable the encryption
      KEY       The key to use in C notation like "\x11\x22\x33\x44" or
                "this is my key" (cstring)
                This value can be also a variable or a memory file
                set ALGO and KEY to "" for disabling the encryption
      IVEC      The ivec to use in C notation (cstring), an ivec is an
                additional key used for increasing the security of
                encryption algorithms that are usually defined as ECB
                without ivec and CBC (and other names) with ivec
      MODE      0 for decryption (default), 1 for forcing the encryption mode
                if no ivec is used remember to place a "" at its place
      KEYLEN    Forces the usage of a certain length of the key, this one
                has been introduced only for avoiding the problem of using
                a variable as KEY containing zeroes in it

    Examples:
      Encryption aes "0123456789abcdef" "" 1    # encryption without ivec
      Log MEMORY_FILE 0 SIZE
      Encryption aes "0123456789abcdef"         # decryption without ivec
      Log "redecrypted_file.dat" 0 SIZE MEMORY_FILE
      Encryption aes "\x12\x34\x56\x78"
      set MEMORY_FILE binary "\x12\x34\x56\x78"
      Encryption aes MEMORY_FILE
      Encryption aes MY_VARIABLE
      Encryption md5 ""

Print MESSAGE

    It prints a string in C notation with the values of the variables if
    their names are specified between '%' chars.
    It's also possible to specify the maximum amount of bytes to
    visualize (or a variable containing such value) and if they must be
    displayed in hex or dump mode specifying some flags after a '|' like
    in the examples:
    - x/h/hex: hexadecimal numbers and chars
    - dump:    hexadecimal dump, left in hexadecimal and right in chars
    - number:  amount of bytes to show
    - var:     variable containing the amount of bytes to show

    Arguments:
      MESSAGE   C notation string, each %VAR% word is converted to its
                value (cstring)

    Examples:
      print "the variable OFFSET of the file %FILENAME% has the value %OFFSET|x%"
      print "this is the first line\nthis is the second line\n"
      print "variable %VAR% and %VAR2%"
      print "variable %VAR|h% and %VAR2|hex%"
      print "variable %VAR|3% and %VAR2|4%"
      print "variable %VAR|3h% and %VAR2|h4%"
      print "variable %VAR|dump16%"
      print "variable %VAR|dumpVARSZ%"

GetArray VAR ARRAY VAR_IDX
and
PutArray ARRAY VAR_IDX VAR

    Experimental commands to store variables in bidimensional arrays.
    They work on a dynamic array where it's possible to store the
    variables. Something like a temporary place or a stack.
    It's highly suggested to pre-allocate the array if you know the
    max value, example: PutArray 0 FILES 0
    If the array index (VAR_IDX) is negative like -1:
    - getarray will take the element located at that position from the
      end of the array, so "getarray VAR 0 -1" will take the last
      element while "getarray VAR 0 -2" will take the one before
    - putarray will ever append the element at the end of the array,
      currently there is no difference if you use VAR_IDX -1, -2, -1000

    Examples:
      PutArray 0 0 FIRST_VAR
      PutArray 0 1 SECOND_VAR
      GetArray FIRST_VAR 0 0
      GetArray SECOND_VAR 0 1
      for i = 0 < FILES
        putarray 0 -1 VAR
      next i


.......................................................................

SortArray ARRAY [ALL]

    Experimental sorting of the arrays in ascending order (like 0 to 99)
    based on the values in ARRAY.
    If ALL is a number different than zero, the sorting will affect ALL
    the available arrays created till that moment, which means that
    their positions will match those of the sorted array, so if the
    array 0 was "1" "3" "2" and array 1 "hello" "test" "bye", with ALL
    set to 1 you will have 1 2 3 and "hello" "bye" "test".

    Examples:
      putarray 0 0 "zzz"
      putarray 0 1 "aaa"
      putarray 0 2 "bbb"
      sortarray 0
      for i = 0 < 3
        getarray TMP 0 i
        print "%TMP%"
      next i

CallFunction NAME [KEEP_VAR] [ARG1] [ARG2] ... [ARGn]
StartFunction NAME
...
EndFunction

    Calling and declaration of a function identified by NAME where the
    values of the variables are backed up till the termination of the
    function when they are restored.
    It works very well for recursive/nested archives like those used by
    "The Void" and "Another Day".
    If KEEP_VAR is not specified or zero, QuickBMS will make a backup
    of the current values and the function will work on a copy, when
    the function terminates the variables will be restored to their
    backup.
    If KEEP_VAR is set to 1, there will be no backup and any change
    made in the function will remain when it terminates.
    Do not use KEEP_VAR if you are working on a nested/recursive file
    table, use it to 1 if you are creating a macro or a function
    called many times to perform a task.
    It's a good idea to place all the functions (from StartFunction
    till EndFunction) at the end of the scripts.
    It's also possible to pass optional arguments to the function, they
    will have the name of the function plus ARGnumber, for example:
    MYFUNCTION_ARG1 amd MYFUNCTION_ARG2.
    Doesn't exist a return value at the moment but it's possible to
    do it in other ways like saving the value in an array or on a
    MEMORY_FILE.

    Arguments:
      NAME      Name assigned to the function
      KEEP_VAR  Set to 1 if you want to keep the content of the variables
                without resetting them, in short words:
                0 = for recursive functions (default)
                1 = for normal functions that change variables,
                    this is faster and suggested in most cases
      ARGs      Arguments, they are seen inside the function as
                "name of the function" + ARG + argument_number

ScanDir PATH NAME SIZE [FILTER]

    Function without a real usage, it simply scans the PATH folder and
    fills the NAME and SIZE variables with the name and the size of
    each file found.
    At the moment this function doesn't have a purpose so ignore it.
    If you want to filter the scanned files located in the folder you
    specified as input, use the -F option of quickbms (I tell this
    information because some users may think to "wrongly" use this
    command for that purpose).

    Arguments:
      PATH      Must be ".", the current folder
                There are also some "experimental" values not meant for
                normal usage, with optional file number after "://"
                (for example heap://10 will work on the file number 10):
                    process://  processes on the system: NAME=process SIZE=pid
                    module://   modules in the opened process: NAME=address SIZE=size
                    memory://   allocated blocks of memory: NAME=address SIZE=size
                    heap://     every single allocated heap (slow!): NAME=address SIZE=size
      NAME      Output variable which receives the name of the file, it
                will be "" when there are no other files
      SIZE      Output variable which receives the size of the file, it
                will be -1 when there are no other files
      FILTER    Same job as -F, this filter is valid only if -F wasn't
                specified

    Examples:
      For
          ScanDir "." NAME SIZE
          if NAME == ""
              cleanexit
          endif
      Next
      ...
      For
          ScanDir "." NAME SIZE "*.jpg"
          if NAME == ""
              cleanexit
          endif

CallDLL DLLNAME FUNC/OFF CONV RET [ARG1] [ARG2] ... [ARGn]

    This is the command which allows to use plugins inside QuickBMS.
    The idea came from the possibility of using the custom
    decompression/decryption functions located in executables and DLLs
    avoiding the boring reverse engineering of all the functions.
    It works with both real files and MEMORY_FILEs (even if they contain
    dll data!).
    Unfortunately this is not much possible with the functions got from
    executables where are used static variables due to some technical
    reasons, in fact it's not possible to relocate them in memory.
    For example if the function uses the memory between 006c0000 and
    006d0000 it's highly possible that such range of memory is not
    allocated or is already in use because the executable has not been
    loaded (LoadLibrary) in its original address, that space is already
    occupied.
    There are no problems with the DLLs, they are made to be relocated.
    You can even use a dll inside a MEMORY_FILE but be sure it's not
    packed because it may not work.
    And it's also possible to use a raw data containing maching
    instructions, basically you can dump a function "as is" and putting
    it in a MEMORY_FILE.
    That means that the following situations are OK:
    - raw dumped functions without references to API or static memory
    - DLLs
    - "maybe" some executables loaded as DLLs

    Arguments:
      DLLNAME   Name of the dll, executable, file or MEMORY_FILE where
                is located the function, example "mylib.dll"
      FUNC/OFF  It can be the name of the function to import in which
                  case it must be exported by the dll/exe with a name
                  (pay attention to mangled names!)
                Or the relative offset where is located the function,
                  remember that the relative offset is NOT the absolute
                  one but it's the offset related to the image base of
                  the exe/dll, so if normally the dll loads at offset
                  10000000 and the function is at 10012345 then the
                  offset is 0x12345
      CONV      Calling convention, please refer to calling_convention.h:
                  usercall: allows to set all the 6 x86 registers, any
                    argument after 6th will be pushed on the stack
                  cdecl: used by default in many C/C++ compiler
                  stdcall: aka winapi, used by default in Visual C
                  thiscall
                  msfastcall: Microsoft fastcall
                  fastcall: native fastcall
                  borland: the fastcall convention used by the Borland
                    compilers like Delphi
                  pascal
                  watcom
                  safecall
                  syscall
                  optlink
                  carion
      RET       The variable which will contain the value returned by
                the function, use "" if there is no return value.
                If you use *RET or &RET then the return value will be
                copied in the RET variable as a string
      [ARGS]    All the arguments of the function, it's also possible
                to use pointers to arguments if they are preceded by a
                & or a * like &SIZE which means that the dll/code
                receives the address of that variable and can modify
                its content. It works only with numeric variables

    Examples:
      idstring LZ2K
      get SIZE long
      get ZSIZE long
      log MEMORY_FILE 0xc ZSIZE
      putvarchr MEMORY_FILE2 SIZE 0 # like malloc
      #calldll "TransformersDemo.exe" 0x263c50 cdecl "" MEMORY_FILE MEMORY_FILE2 ZSIZE SIZE    # 00663C50
      calldll "unlzk.dll" "unlz2k" cdecl SIZE MEMORY_FILE MEMORY_FILE2 ZSIZE SIZE
      log "dump.dat" 0 SIZE MEMORY_FILE2


.......................................................................

Put VAR TYPE [FILENUM]
...
PutDString VAR LENGTH [FILENUM]
...
PutCT VAR TYPE CHAR [FILENUM]
...

    These commands are EXACTLY like the Get* functions except for the
    fact that they perform write operations.
    For using these commands on a physical file (so MEMORY_FILEs
    excluded) the user MUST use the -w option at runtime, that's
    necessary for both technical and security reasons.
    If you want to write a string without the NULL delimiter use:
    putct "your_string" string -1


.......................................................................

GetBits VAR BITS [FILENUM]

    This is an experimental function for reading bits from the files.
    When you use a GoTo function or change the current offset of the
    file with a Get* command, the variable containing the bit position
    (basically the amount of bits read from the previously byte taken
    from the file) will be reset to 0.
    Note that the function is 100% endian compatible so the result
    changes if you choose the little or big endian mode, remember it in
    case the results don't match what you expected.

    Arguments:
      VAR       Destination variable, can be a number if the bits are
                from 0 to 32 or a string for bigger sizes
      BITS      Number of bits to read
      FILENUM   Number of the file associated to the archive (0)


.......................................................................

PutBits VAR BITS [FILENUM]

    Write mode, same format as GetBits


.......................................................................

Include FILENAME

    This command loads another script in the current one, it can be
    useful if you have many general functions and you want to avoid to
    copy&paste them in any new script.
    You can place it in any part of your script.

    include "general.bms"
    ->
        load the part of the current script till "include"
        load general.bms
        load the remaining part of the current script after "include"


.......................................................................

NameCRC VAR CRC [LISTFILE] [TYPE] [POLYNOMIAL] [PARAMETERS]

    It's not rare to have archives containing files without names, just
    a crc (checksum) calculated on the original filename to identify it.
    The NameCRC command exists just in these situations, where you have
    a file containing a list of filenames (maybe collected with a
    debugger or via hooking) and you want to assign them to the output
    files.
    What this command does is just loading the names in LISTFILE,
    calculating some checksums on them using the provided crc
    parameters, and compare the CRC field read in the archive with the
    calculated ones.
    When a crc matches the one in the database, the original filename
    is moved in the VAR variable.
    Note that QuickBMS will automatically calculate various CRC for the
    same filename, by using only slash or backslahs, or all the chars
    to lower or upper case, by removing any "\/.:" char from the
    beginning of the name and so on. This is necessary to grant the
    catching of the right filename in any situation.
    The feature is very fast and the "database" is not so big, so you
    will notice almost no performance issues while using this command.

    The function must be used before the *log operations and it can be
    used as initializer at the beginning of the script and then with
    only the first mandatory arguments to retrieve the filenames
    matching the provided crc, for example:
        namecrc DUMMY 0 "names.list" 32
        ...
            get NAME_CRC long
            namecrc NAME NAME_CRC
            log NAME OFFSET SIZE

    Or you can just use it with all the arguments:
        ...
            get NAME_CRC long
            namecrc NAME NAME_CRC "names.list" 32
            log NAME OFFSET SIZE

    Arguments
        VAR     Destination variable that will contain the filename or
                just a "" in case no name has been found (it will use
                a particular variable called QUICKBMS_FILENAME).
                If VAR is "" then you can use *log "" and the retrieved
                filename will be automatically applied to the output
                file. This behaviour has been thought to write scripts
                easily without providing a NAME variable.
        CRC     This is the CRC field read from the file.
                It must be a HEXADECIMAL value, decimal are no longer
                supported by default.
                Remember that quickbms.exe reads longlong as a 32bit
                field, you must use quickbms_4gb_files.exe to read real
                64bit fields.
                If necessary, in future will be supported also hash
                algorithms.
        LISTF   The name of the file that contains the filenames, each
                name must be on a new line.
                QuickBMS automatically recognize if the entry is just
                the name or contains also a pre-calculated crc, for
                example:
                    path\folder\file.txt
                    0x11223344  path\folder\file.txt
                    287454020           path\folder\file.txt
                    # path\folder\file.txt
                The list file will be automatically searched and loaded
                from the input and output folders, till it's found.
                The filenames located after a comment are good to use
                the same bms script as a file list.
                You can also specify a memory file, useful if you have
                set it as compressed, set MEMORY_FILE10 compressed "..."
        TYPE    Currently only CRC is supported:
                crc32 (default), crc8, crc16 and crc64
        POLY    The polynomial value used to calculate the CRC tables
        PARAM   Both POLY and PARAM work in the same way you can set
                the CRC in the Encryption command through KEY and IVEC,
                so refer to that command for additional information and
                example.
                Anyway PARAM contains:
                BITS, INIT, FINAL, TYPE, REVER and BITMASK_SIDE
                If you are a developer and wants to have a full
                understanding of what you can customize, please check
                the crc_calc function in crc.c, it's very simple and
                self explanatory.


.......................................................................

Codepage VAR

    Allows to specify a codepage/charset (number or name) for the unicode
    operations like "getdstring VAR2 SIZE ; Set VAR1 unicode VAR2".
    Currently it works only on Windows and the full list of codepages
    is available at:
    https://msdn.microsoft.com/en-us/library/windows/desktop/dd317756%28v=vs.85%29.aspx

    Arguments
        VAR     the codepage, like utf8 or 950 and so on.

    Example for converting a string from JIS (932) to UTF8:
      get NAME string           # read it as a sequence of bytes
      codepage 932
      set NAME to_unicode NAME  # jis -> utf16 (unicode)
      codepage "utf8"
      set NAME unicode NAME     # utf16 -> utf8


.......................................................................

SLog NAME OFFSET ZSIZE [TYPE] [FILENUM]

    This command allows to export strings to an output file and being
    able to reimport them later with reimport.bat.
    The reimporting feature of this command has the same limitations of
    the global one, so you cannot reimport strings that are longer than
    the original.
    Currently QuickBMS will simply tell you that the new string is longer
    without interrupting the importing so pay attention.
    The space between the end of the new and old string will be filled
    with zeroes but this behaviour "may" be changed in future to avoid
    situations in which there are sequential NULL delimited strings and
    using zeroes will causes problems in the software that reads the
    file. Anyway in these situations you can just insert the spaces by
    yourself in the new string.
    The dumped strings are handles as C strings, basically the '\' char
    (backslash) is an escape that allows you to specify any byte you
    desire, the \r and \n you will see are just the 0x0d and 0x0a bytes
    that allow to insert the whole multiline string in one line.
    Each line is an exported string.
    Notepad++ highly suggested.
    Small tip: Use INS (the replace character) mode of your text editor
    for editing the string file to reimport so that you will have no
    problems with longer new strings.
    The SLog function is new so any feedback and suggestion is highly
    appreciated.

    Arguments:
        NAME    Name of the output file. It will be created from scratch
                the first time and then will be used in append mode from
                the second line on. Automatic, simple and error-proof.
                The output file is just in UTF-8 with Windows line feeds
                ("\r\n") and the conversion of unicode strings is performed
                by QuickBMS automatically with the codepage in use
        OFFSET  The offset where is located the string you want to dump.
                >=0 works just like the other *log commands and dumps
                    the string located at that OFFSET, it doesn't change
                    the current offset
                <0  dumps the string at the current offset and updates it,
                    so it advances in the file
        SIZE    >=0 it works just like the Getdstring command allowing
                    you to dump a string of a certain amount of bytes
                <0  just like the Get command
        TYPE    This is the type of data to read just like the Get
                command, if not specified it's considered String. You can
                dump most of the types and even the non-string ones so if
                you use the Long type you will have the decimal value easy
                to edit inside the output file
        FILENUM the input file

    Examples:
      # the test file is available here http://aluigi.org/bms/slog_test.dat
      set STRINGS_FILE string "strings.txt"
      slog STRINGS_FILE -1 0xb string
      slog STRINGS_FILE -1 -1
      slog STRINGS_FILE -1 -1 long
      endian big
      #slog STRINGS_FILE -1 -1 unicode
      slog STRINGS_FILE -1 0x18 unicode
      slog STRINGS_FILE 0x2e -1


.......................................................................

QuickBMS can handle also some minimalistic and experimental C
structures like:

  debug 1     # needed to show the collected information
  struct test {
    int       var1;
    char      var2;
    char      *mystring;
    uint8_t   data[10];
  }

These operations are all converted to Get* commands while they are
converted in Put* if there is a '=' after them, like:

  debug 1
  struct test {
    int       var1 = 0x11111111;
    char      var2 = 0x22;
    char      *mystring = "hello";
    uint8_t   data[10] = OTHER_VAR;
  }

Maybe in future versions it could be improved but at the moment it's
tagged as an experimental and alternative feature only in case you
don't know the bms syntax or it takes time to convert a C struct in
bms language.

Example of -s option, zlib decompression in one command-line without
using script files:

  quickbms -s "comtype zlib ; get ZSIZE asize ; xmath SIZE \"ZSIZE * 10\" ; clog \"dump.dat\" 0 ZSIZE SIZE" "" input_file.dat output_folder


#######################################################################

================================================
5) Experimental input and output, other features
================================================


A] Experimental input and output
--------------------------------

From version 0.5.1 of QuickBMS I started to implement some alternative
input/output methods.
At the moment these alternatives cover the following operations:

- Network socket operations specified by an URL like udp:// and tcp://
  so the tool can be used to send custom packets and data via TCP and
  UDP to one or more network hosts.
  Required command-line option: -n or -network
  URL format:
    tcp://host:port
    tcp://host:port,ssl,force_new_socket

- Process operations specified by an URL like process:// or memory://
  and allow to read and write the various processes running on the
  system.
  Required command-line option: -p or -process
  URL format:
    process://process_name
    process://pid
    process://pid:module_name

  Experimental debug mode available by adding "debug" after the
  parameters: process://pid/debug
  In this way the process will be debugged by QuickBMS and when
  there is a breakpoint or an exception the process will be freezed
  and all the registers dumped in variables with their names.
  additionally QuickBMS will keep in memory all the INT3 you set
  and automatically restore them when you want to continue the
  execution.
  You can find an example script here:
    http://aluigi.org/bms/simraceway_getkey.bms

- Audio operations specified by an URL like audio:// or wave://
  and allow to record audio from the default input device (like
  microphone) and play.
  Currently the "device" parameter is not used.
  Required command-line option: -A or -audio
  URL format:
    audio://device,sample_rate,channels,bits

- Video operations specified by an URL like video:// or graphic://
  and allow to grab the screen and display the images.
  set window_name to null or none for using the whole screen in read
  mode.
  Required command-line option: -g or -video
  URL format:
    audio://window_name,width,height,bits

- Windows messages specified by an URL like winmsg:// but at the moment
  it's possible only to send messages and using 3 long numbers:
  message, wparam and lparam.
  Required command-line option: -m or -winmsg
  URL format:
    winmsg://window_name


I had this crazy idea in my mind for over one year and I decided to
implement it now just because it's completely crazy and can work only
if the user uses the needed options at command-line for security
reasons.

After all QuickBMS implements a lot of algorithms so for me it's a lot
more comfortable to be able to use it for my tests with the network
data and I guess some modders could find useful the process operations
for dumping textures and other models directly from the memory.
Anyway keep in mind that this is all experimental stuff.

The following is an example script for the network operations:

  log MEMORY_FILE 0 0
  put 0x11111111 long MEMORY_FILE
  put 0x22222222 long MEMORY_FILE
  put 0x33333333 long MEMORY_FILE
  put "hello" string MEMORY_FILE
  put 0x44444444 long MEMORY_FILE
  get SIZE asize MEMORY_FILE
  log "tcp://127.0.0.1:1234" 0 SIZE MEMORY_FILE
  log "udp://localhost:1234" 0 SIZE MEMORY_FILE

or

  log MEMORY_FILE 0 0
  put "GET / HTTP/1.0" line MEMORY_FILE
  put "User-Agent: Mozilla" line MEMORY_FILE
  put "Referer: http://localhost/test.htm" line MEMORY_FILE
  put "" line MEMORY_FILE
  get SIZE asize MEMORY_FILE
  log "tcp://127.0.0.1:80" 0 SIZE MEMORY_FILE

Command-line:
  quickbms -n script.bms "" ""

While the following is a simple HTTP download that can be used with
  quickbms -n script.bms "tcp://aluigi.org:80" "" > output.htm

  get HOST filename
  string HOST p= "Host: %s" HOST
  put "GET / HTTP/1.1" line
  put HOST line
  put "User-Agent: Mozilla" line
  put "Connection: close" line
  put "" line
  for
      get DATA line
      print "%DATA%"
  next

Funny example that inverts the colors of the first notepad window:

  set NAME string "video://notepad"
  open "" NAME
  get SIZE asize
  filexor 0xff
  log NAME 0 SIZE

Launch notepad and then run:
  quickbms -g script.bms "" ""

How to close Firefox:
  put 18 long   # WM_QUIT
  put 0 long    # wParam
  put 0 long    # lParam

  quickbms -m script.bms "winmsg://firefox" ""

In future I could decide to add other operations and I'm interested in
any other idea.



B] Other features
-----------------

Other experimental features are the support of most of the commands
used in templates of WinHEX:
http://www.x-ways.net/winhex/templates/index.html

Usually these templates work immediately while sometimes it's necessary
only to separate some arguments manually like "arg1""arg2" to
"arg1" "arg2".

QuickBMS has also the great feature of dumping an HTML file with the
parsed format highlighted through the option -H.
This is a very cool feature that can help many people and doesn't
require additional modifications, just use the original BMS scripts as
usual.
Unfortunately the generated HTML file is not optimized yet and so it
takes lot of memory and CPU to be loaded.

The QuickBMS process supports some return code numbers used when the
tool terminates due to a success or a fail, you can find the list at
the beginning of src\defs.h.
QUICKBMS_OK (success) is ever 0 while QUICKBMS_ERROR_* are referred to
problems.



C] Modkit distribution of quickbms.exe
--------------------------------------

In response to a request of a modder, I have decided to add a simple
feature to allow modders and modkits developers to embed a script in
quickbms.exe when they distribute it in their products, so the user
will not be asked to select the script.

How to do it:

- open quickbms.exe with a hex editor
- search the string "SET THIS BYTE X TO 0X00"
- replace the 'X' with 0x00:
  53 45 54 20 54 48 49 53 20 42 59 54 45 20 58 20   SET THIS BYTE X
  53 45 54 20 54 48 49 53 20 42 59 54 45 20 00 20   SET THIS BYTE  

- upx.exe -9 quickbms.exe

- copy /b  quickbms.exe  +  script.bms   output.exe

That's all, anyway if you want to use the "classical" way and being
able to specify options, input file and output folder, it's better to
use the BAT solution with the -G option for the GUI mode:

  EXTRACT.BAT:
    quickbms.exe -G OPTIONS SCRIPT INPUT OUTPUT

========
6) Notes
========


The following are some exceptions in the usage of QuickBMS.
They are not real bugs, rather they are things that can't work (at
least at the moment) due to the very flexible nature of the tool or
things that it's useful or interesting to know:

? (partially solved)
  Number and strings, due to the usage of the optimizations the following
  script will NOT result in "mytest46600x12349999999999", the result will
  be "mytest4660-1717986919":
    set NAME string "mytest"
    set NUM long 0x1234
    string NAME += NUM
    print "%NAME%"
    set NUM string "0x12349999999999"
    string NAME += NUM
    print "%NAME%"
  This is a good compromise because the previous situation is very very
  "rare" and in any case can be bypassed using multiple "string NAME += chr"
  and the gain in performance is incredible for the multiple in-script
  operations, so this is the best solution.
  Additionally you can use the printf-like string command and the binary
  type with Set:
    set NAME string "mytest"
    set NUM1 long 0x1234
    set NUM2 binary "0x12349999999999"
    string NAME p= "%s0x%x%s" NAME NUM1 NUM2
    print "%NAME%"

- Any Clog operation with a compressed or uncompressed size minor/equal
  than zero produces a file with a zero size, but this is not a problem
  of the tool because it's the perfectly logical behavior in these
  situations.
  If it's necessary to use a compression which gets the SIZE value
  automatically (like base64 or stalker_lza) is enough to specify the
  compressed size as uncompressed size:
    clog NAME OFFSET ZSIZE ZSIZE
  or
    clog NAME OFFSET ZSIZE 1

- The tool has been created to be 100% compatible with the original
  MexScript language and its syntax/logic, so I tried to add not many
  new commands and, if possible, providing an alternative using
  the original set of commands (for example the Strlen command and
  "Set VAR strlen VAR").
  I tried also to maintain the logic of the program (for example
  encryptions and compressions applied in the file operations only).
  So if something looks complex or senseless, it has been made for
  matching the original structure and logic of the scripting language.

- QuickBMS grants compatibility with the original MexScript language
  that implements also some static and partially undocumented variables
  like:
    EXTRCNT, BytesRead, NotEOF, SOF, EOF
  If you are writing a script for QuickBMS try to avoid these variable
  names except if you really need and know what they do.

- QuickBMS uses many third party code and, even if I tried to adjust
  them a bit where possible, unfortunately many of these external
  functions were a disaster or missed any security requirement.
  That's the reason why the comtype scanning feature causes so many
  crashes with invalid data.
  From version 0.5.5 I added a particular type of allocation management
  that allows a better debugging of the code and at the same time
  protects the heap from contiguous buffer overflow and underflow
  (so it can do nothing against "buff[0x11223344] = 'a').
  It's not a solution but at least helps me a lot and limits the
  problems caused by third party non-safe code.
  The only protection of the stack is provided by the
  -fstack-protector-all compiler option of Gcc.

- Security:
  It's hard to make the tool completely safe, anyway the following are
  some notes and solutions:
  - allocated memory set as read/write only with guarded page before and
    after the buffer, they act like a "cage" that delimits the buffer
  - usage of Gcc -fstack-protector-all
  - the user is EVER prompted of activating dangerous features like the
    usage of dlls and the calling of external executables
  - some checks to avoid the problems caused by the big redundant code
    of which QuickBMS is full (unfortunately, sorry for that)
  - keep in mind that QuickBMS is mainly a testing tool in which I
    preferred to insert strange and particular features rather than
    making it "secure" for any user, it's the responsibility of the user
    to use only trusted scripts and paying attention to the warnings
    displayed by the tool

- The EXECUTE mode of ComType and Encryption will grant compatibility
  with any compression and encryption tool (command-line) based on
  algorithms not yet supported by QuickBMS, and at the same time avoids
  the rush of trying to implement "everything" as soon as possible.
  I used system() for this command just because I want that it's
  compatible with any possible program included those which require
  input from stdin and output to console (stdout).
  Example: "file.exe < #INPUT# > #OUTPUT#"

? (partially solved)
  All the extracted files are loaded completely in memory before being
  dumped for various technical reasons, so if the file to dump has a
  size of 800 megabytes this is the same size which will be allocated
  in memory or even double or more if the file must be decompressed, so
  it's good to have a good amount of free RAM when handling big archives
  or at least a good virtual memory/swap space.
  This mechanism is not used for files that don't require encryption
  and compression in which case the operation is performed 1:1 using
  a temporary buffer of only 1 megabyte.

x (SOLVED!)
  Log "123.txt" OFFSET SIZE
  It creates the file 123 and not 123.txt, this happens because "123.txt"
  is considered a constant number due to the rule that everything
  starting with a number (or a '-') is handled as a constant number.
  This behavior didn't happen with the previous versions of the tool
  because wasn't used the number optimization which saves tons of CPU
  cycles in some scripts.
  * From version 0.3.12 I decided to implement the full verification of
    the string to know if it's a number or a string, luckily there is
    almost no loss of performances

x (SOLVED!)
  The following do NOT work because the QuickBMS variables are case INsensitive:
  if SIGN == "test"     # u== is the same
  elif SIGN == "TeSt"
  ...
  set SIGN1 binary "test"
  set SIGN2 binary "TeSt"
  if SIGN == SIGN1      # u== is the same
  elif SIGN == SIGN2
  ...
  The only way to fix it would be to make quickbms case SENSITIVE, this
  change should give no problems if you have written the scripts correctly
  but exists a 1% of possible issues, currently I don't know what to do.
  .
  * From QuickBMS 0.5.31 you can use the -I option to force the case
    sensitive mode on variable names

x (SOLVED!)
    set NAME string MEMORY_FILE
    log NAME 0 0
  It produces no physical file because it's considered a MEMORY_FILE, it
  happens because the dumping function receives "MEMORY_FILE" as output
  file name.
  At the moment there is no fix anyway it's a very very rare event
  (never happened to find an archive containing a file with that name)
  and so not a priority.
  * Fixed in version 0.5.17 by checking if the name of the file is the
    name of a variable or its content.

x (SOLVED!)
  Crash caused by HsSrv.dll.
  The Asus Xonar and Unixonar drivers cause the crash of QuickBMS for the
  following reason: HsSrv.dll is automatically injected in any process
  and this dll checks all the allocated memory for the presence of a "MZ"
  signature (the one used for the executables):
    1000B462  CALL DWORD PTR DS:[<&KERNEL32.VirtualQuery>]
    1000B468  TEST EAX,EAX
    1000B46A  JBE SHORT 1000B4BE
    1000B46C  CMP DWORD PTR SS:[EBP-24],1000    ; check if State is MEM_COMMIT
    1000B473  JNE SHORT 1000B48B
    1000B475  TEST WORD PTR SS:[EBP-20],0100    ; check if Protect contains PAGE_GUARD
    1000B47B  JNZ SHORT 1000B48B
    1000B47D  AND DWORD PTR SS:[EBP-4],00000000
    1000B481  CMP WORD PTR DS:[ESI],5A4D        ; check if the buffer starts with MZ
  QuickBMS uses a particular memory protection mechanism that in the
  recent versions switched from PAGE_GUARD to PAGE_NOACCESS, that's
  why HsSrv.dll crashes: if Protect contains PAGE_GUARD then it skips the
  MZ check but now it's PAGE_NOACCESS.
  Using MEM_COMMIT | MEM_RESERVE doesn't help to skip the code with the
  first check because VirtualQuery returns only MEM_COMMIT.
  Asus should fix the bug by checking if Protect is set to a non-readable
  flag, I have NOT contacted them.
  Some possible solutions are the following:
  - disable the GX mode (emulated EAX) of the Asus driver
  - disable the Asus HookSupport Manager application (HsMgr.exe)
  - start QuickBMS with the -9 option (create a shortcut)
  - contact Asus! :)
  Note that the problem seems to happen only when QuickBMS is launched
  with the GUI (double-click) while it's calling the Windows API
  GetOpenFileName.
  * From version 0.5.25c I use PAGE_GUARD to avoid any problem with
    buggy third party drivers.

? When you assign a string to a variable pay attention to the backslash
  char: \
  It's used as escape when parsing the bms script and a quoted string
  is found, like "test".
  The only limitation is caused by the presence of the same quote char
  after the backslash so the following command is wrongly interpreted:
    string VAR R "test1 and test2\" "/"
  In that case the \" is interpreted as " without terminating the
  handling of the quote string.
  For that specific case there is no solution at the moment because
  \\ is interpreted as \\ and not as \.
  Consider that this is a very rare case and if you want to replace
  the backslash with slashes it's enough to use:
    string VAR R \ /


Other things to know or strange behaviors will be listed when I will
figure and remember them.

A curiosity for who is crazy for the optimizations of the compilers:
the PPMD (ppmd var.i rev.1) algorithm compiled with -O3 (Gcc) is a lot
slower than if compiled with -O2 and a similar situation is valid also
for other algorithms.
With -Os the code is smaller (about 300kb the Windows exe of an old
quickbms version) but there is a loss of performances of max 15/20%
with some algorithms (like PPMD) and scripts with many get/putvarchr
and math operations.

Notes:

- Some (many?) of the original codes have been modified a bit to make
  them usable in QuickBMS for the memory2memory (aka in-memory)
  decompression and for other possible fixes or for decreasing the
  amount of code, for example removing the compression routine leaving
  only the decompression one.
  Note that I avoided to make this third-party code more secure because
  it's not the job of QuickBMS, so almost all the code (except some
  rare cases) has been used "as-is", the only security protections come
  from the general protection mechanisms adopted in QuickBMS like my
  own heap handling and -fstack-protector-all.

- The files/libraries which have been modified have the header
  "// modified by Luigi Auriemma" which is meant just to show that it's
  not the 100% original code and it must be NOT considered like a
  credit.
  I claim nothing about them, the original license and authors are
  still untouched.

- If the files have been modified or don't have the original license
  information (may happen only with small functions that didn't contain
  a license header in origin) please follow the provided links for more
  details.

- Almost all the algorithms implemented here have been selected by me
  because they:
  - have been used
  - "may" have been used
  - it has been claimed to have been used
