    GCBASIC /version
Switch Description Default

/O:filename

Sets the name of the assembly file generated to filename.

Same name as the input file, but with a .asm extension.

/A:assembler

Batch file used to call assembler(1). If /A:GCASM is given, GCBASIC will use its internal assembler.

The program will not be assembled

/CP

Exports the config bits automatically selected by the compiler to an output file called source_filename.config. The output file is the source filename with the extension of config.

None

/H:[Y/1 | N/0]

Set the production, or not, of the hex output file. /H:1 is the default. To prevent production of the hex output file - use /H:0

The default is to produce the hex output file

/M:[Y/1 | N/0]

Mute the banner messages, or not. /M:1 is the default. To prevent banner messages - use /M:0

The default is to output banner messages

/P:programmer

Batch file used to call programmer(1). This parameter is ignored if the program is not assembled.

The program will not be downloaded.

/K:[C|A]

Keep original code in assembly output. /K:C will save comments, /K:A will preserve all input code.

No original code left in output.

/V[:[0|F][1|T]

Verbose mode - compiler gives more detailed information about its activities. /Vx will overide any configuration in the user ini file.

-

/L

Show license and exit.

-

/NP

Do not pause on errors. Use with IDEs.

Pause when an error occurs, and wait for the user to press a key.

/WX

Force compiler to ensure all include files are valid.

  

/version

Shown build date and version of the compiler.

  

/S:fsp

Load the settings from a specified file, rather than use the defaults.

/S:use.ini

/F[:[0|F][1|T]

Used to bypass compilation when not needed, compiler will verify that config settings in the already compiled file match those required for the programmer. If not, a recompilation will be forced. Skip compilation if the hex file is up to date and has correct config. /F:x ( F or 0) to force a fresh compile regardless of what ini specifies.

 

/FO

Used to bypass compilation and program only. Compiler will verify that config settings in the already compiled file match those required for the programmer. If not, a recompilation will be forced.

 

filename

The file to compile.

-

(1) For the /A: and /P: switches, there are special options available. If %FILENAME% is present, it will be replaced by the name of the .asm file. %FN_NOEXT% will be replaced by the name of the .asm file but without an extension, and %CHIPMODEL% will be replaced with the name of the chip. The name of the chip will be the same as that on the chip data file.

A batch file to load the ASM from GCBASIC into MPASM. Command line should be like this: 

    C:\progra~1\microc~1\mpasms~1\MPASMWIN /c- /o- /q+ /l- /x- /w1 %code%.asm

A batch file to compile in GCBASIC then load the ASM from GCBASIC into GPASM. Command line should be like this: 

    gcbasic.exe %1 /NP /K:A /A:"..\gputils\bin\gpasm.exe %~d1%~p1%~n1.asm"

To instruct MAKEHEX.BAT to use GPASM. You have GPUTILS installed. The batch file should be edited as follows: 

    REM Create the ASM
    gcbasic.exe /NP /K:A %1
    REM Use GPASM piping to the GCB error log
    gpasm.exe "%~d1%~p1%~n1.asm" -k -i -w1 >> errors.txt

To summarise, you can use any of the following:

    gcbasic.exe filetocompile.gcb /A:GCASM /P:"icprog -L%FILENAME%" /V /O:compiled.asm

GCBASIC will compile the file, then assemble the program, and run this command:

    `icprog -Lcompiled.hex`

You can also create/edit the gcbasic.ini file :

Assembler settings
    Assembler = C:\Program Files\Microchip\MPASM Suite\mpasmwin
    AssemblerParams = /c- /o- /q+ /l+ /x- /w1 "%FileName%"

Programmer settings
    Programmer = C:\Program Files\WinPic\Winpic.exe
    ProgrammerParams = /device=PIC%ChipModel% /p "%FileName%"

This example will use MPASM to assemble the program. It will run the program specified in the assembler = line, and give it these parameters: 

    `/c- /o- /q+ /l+ /x- /w1 "compiled.asm"`

Then, it will run the programmer, and give it these parameters when it calls it:

    `/device=PIC16F88 /p "compiled.hex"`

%ChipModel% will get replaced with the chip you are using, so this the chip GCBASIC will pass to WinPIC.

Errors.txt

The compiler only produces the file errors.txt if there is an error. The creation of the errors.txt file makes it easier for IDEs to detect if the program compiled successfully - if the file was not produced then the IDE would be unalbe to present the error message to the user.

The file error.txt is always produced in the same folder as the compiler. Typically: C:\GCStudio\GCBASIC\Errors.txt

USE.INI

USE.INI is the provided setup file for the compiler.  The name of use.ini is historic and of no relevance.

USE.INI is generally updated by using the PREFERENCES EDITOR.  

USE.INI is self documenting and open use.ini in an editor will shown the full capabilities of setting file.

The details below show the self documentation in a typical use.ini

Preferences file for GC BASIC
Location: GCB install (or custom) dir
