The ZC32 compiler translates a subset of the C language into ZASM assembly language. ZC compiler is based on source code of Small C compiler by J. E. Hendrix, and SmallC32 port by done by Hans Walheim.

ZC32 supports arrays of one dimension. Functions always return return integer values. Initialization of global variables is supported. The preprocessor supports #include, #define, #ifdef, #ifndef, #else, #endif, #asm, #endasm commands.

The following control statements are supported: if, switch, case, default, break, continue, while, for, and do/while. All expression operators are supported. Only integer and character data types are supported (integers are considered floats here at same time).

The following standard C features are not supported: structures, fields, unions, arrays of pointers, and casts.

Unpack ZC32 into CPUChip, or any other convenient folder. Try running test program, if it compiles - proceed. Else consult troubleshooting (readme.txt).

Modify batch to your needs.

CPUChip folder is situated in [/b]/SteamApps/<yourname>/garrysmod/garrysmod/data/cpuchip/[b]


Usage:
zc.bat file should basic batch file to compile your source code. It's pretty straightforward if you are at least slightly familiar with batches.

Command line
ZC <filename1> <filename2> ... <-m> <-a> <-p>

Parameters:

• [-M] - Monitor status
• [-A] - Beep on error
• [-P] - Pause on errors
• [-NO] - No optimization

CLIB
CLIB is the default library which provides very basic service (port I/O and some stuff the compiler needs there). There are additional libraries available, see "lib" folder, and also see example program.

Some library functions (mostly string ones):
strcmp(str1,str2) - compare strings str1 and str2 (fast version of strncmp)
delay(time) - wait time in miliseconds
curtime() - CPU time in seconds
strcat(s, t) - concatenate t to end of s; s must be large enough
strchr(str, c) - return pointer to 1st occurrence of c in str, else 0
strcpy(s, t) - copy t to s
strlen(s) - return length of string s
strncat(s, t, n) - concatenate n bytes max from t to end of s; s must be large enough
strncmp(s,t,n) - compares two strings for at most n characters and returns an integer >0, =0, or <0 as s is >t, =t, or <t.
strncpy(dest, sour, n) - copy n characters from sour to dest (null padding)
strrchr(s,c) - search s for rightmost occurrance of c. (s - pointer to string to be searched, c - character to search for). returns pointer to rightmost c or NULL.
abs(nbr) - returns absolute value of nbr
isascii( c ) - return 'true' if c is an ASCII character (0-127)
sign(nbr) - return -1, 0, +1 depending on the sign of nbr
toascii( c ) - return ASCII equivalent of c
tolower( c ) - return lower-case of c if upper-case, else c
toupper( c ) - return upper-case of c if it is lower-case, else c
atoi(s) - convert s to integer.
utoi(decstr, nbr) - convert unsigned decimal string to integer nbr; returns field size, else -1 on error
xtoi(hexstr, nbr) - convert hex string to integer nbr; returns field size, else -1 on error
pad(dest, ch, n) - place n occurrences of ch at dest.
left(str) - left adjust and null terminate a string
itox(nbr, str, sz) - converts nbr to hex string of length sz, right adjusted and blank filled, returns str; if sz > 0 terminate with null byte; if sz = 0 find end of string; if sz < 0 use last byte for data;
itod(nbr, str, sz) - convert nbr to signed decimal string of width sz, right adjusted, blank filled; returns str; if sz > 0 terminate with null byte; if sz = 0 find end of string; if sz < 0 use last byte for data;
itoa(n,s) - convert n to characters in s
itoab(n,s,b ) - convert "unsigned" n to characters in s using base b.
reverse(s) - reverse string in place
outport(port,value) - output value to port
inport(port) - input value from port

There's more console functions in CONLIB.C, and math functions in MATH.C.


CONLIB usage:
Wire Console Screen to MemBus, and use drawing functions.

If you are using Address Bus, you need to call setoffset(<new console screen offset>) (offset must be 65536+what_you_have_on_address_bus).

Release 9, fixed wrongful assumption that DS = SS

[Imdsm]

zomg, awesome!

[Whodunnit]

you forgot to update teh string that says version 8 in -h :P

[McLovin]

For some reason, some of the conlib functions don't work. :/

I don't understand. I download it and get a .rar file. What do I do with it?

[Officer Tibbles]

Extract the Rar? :| L2WinRar

[Whodunnit]

if you dont know about .rar files or how to use google , then ZC or zcpu is too complicated for you at the moment.

[Die Nacht]

I just never heard about .rar files (never used them. I always see ZIP, and windows takes care of that).

Thanks though.

it'll be so cool to make apps for alcyoneOS with this and the bios libary, i already know some c.
