# C02
|
|
|
|
C02 is a simple C-syntax language designed to generate highly optimized
|
|
code for the 6502 microprocessor. The C02 specification is a highly
|
|
specific subset of the C standard with some modifications and extensions
|
|
|
|
The compiler generates assembly language code, currently targeted to the DASM assembler.
|
|
|
|
See the top-level [documentation](doc/c02.txt) for more information.
|
|
|
|
## Building the Compiler
|
|
In Linux, use gcc and the [Makefile](./Makefile).
|
|
|
|
In Windows use the [Pelles C IDE](http://www.smorgasbordet.com/pellesc/) and the file [./C02.ppj](c02.ppj).
|
|
|
|
## Compiling C02 programs
|
|
At a command line, cd into the appropriate directory, e.g. [py65](py65/) or [vic20](vic20/).
|
|
|
|
Execute the c02 compiler from the parent directory using the c02 source file (without the .c02 extension) as an argument.
|
|
|
|
For example, to compile the program [conds.c02](py65/conds.c02), in the [py65](py65/) directory, use the command
|
|
|
|
../c02 conds
|
|
|
|
in Linux, or
|
|
|
|
..\c02 conds
|
|
|
|
in Windows.
|
|
|
|
Some of the subdirectories contain a c02.bat file, which will compile the .c02 program, then run dasm to assemble the code. However, the path to dasm is hardcoded, so you will likely need to change it.
|
|
|
|
The file [c02.sh](./c02sh) provides the same functionality in Linux, but it may not be in a working state.
