Here you will find a small INTCODE interpreter written in C. The code not only compiles using CC65 (C64),
but also with GCC, Laser C (ATARI ST), Megamax C (ATARI ST), Pure C (ATARI ST) and Sozobon C (Atari ST).

Which means, it should compile on just about anything. Unlike other icint's, this one includes
all of ICLIB and BLIB inside the interpreter, so, you don't need to include extra INTCODE.

There are a lot of things that can be done to improve this system including:

1) Reducing the size of the BCPL compile by ripping out code.
2) Outputting OCODE as numbers which then are read back into cgi.
3) Using more of the native functions in BLIB.
4) Storing binary versions of trni, syni and cgi on disk, instead of loading INTCODE.
5) Joining trni and syni into one file.
6) Providing a console interface for compiling bcpl programs.

To compile icint.c using cc64 use:
cl65 -O icint.c

I've included the text editor from Kyan Pascal Pro, so to edit bcpl files use:
LOAD "ED",8
RUN
and enter the file name TEST.B

To compile BCPL to OCODE use:

LOAD "ICINT",8
RUN
ICFILE=syni
ICFILE=trni
ICFILE=<enter>
INPUT=test.b
OUTPUT=<enter>

To compile OCODE to INTCODE use:

LOAD "ICINT",8
RUN
ICFILE=cgi
ICFILE=<enter>
INPUT=ocode
OUTPUT=<enter>

To execute the resulting INTCODE use:

LOAD "ICINT",8
RUN
ICFILE=INTCODE
ICFILE=<enter>
INPUT=<enter>
OUTPUT=<enter>
Hello there BCPL fans!

You can also compile the original BCPL KIT sources on the C64.
