ACC

ACC is the official ACS compiler.

Alternative ACS compilers: BCC, GDCC.

Known bugs

256 function limit

ACSUtils has a lot more than 256 functions, but official releases of ACC can't compile programs with more than 256 functions.

To fix this, download the April 26, 2017 development version of ACC (unofficial build for Windows): http://acsutils.strangled.net/lib/exe/fetch.php?media=acc-1.56-beta-g3256a3e.zip

Mixing strings and numbers in an array corrupts the numbers

int SomeArray[] = {
1,
3.14159,
"string"
}

Can result in 1 and 3.14159 getting corrupted.

ACC incorrectly writes initial array values, resulting in some numbers getting interpreted as string indices and recalculated to avoid string index conflicts between libraries.

This bug only affects non-local arrays and happens randomly, usually only with large arrays.

To avoid this bug, do not use static initialization with non-local arrays, instead, declare an empty array and initialize it in a function:

int SomeArray[3];
function void InitArrays()
{
int i = 0;
SomeArray[i++] = 1;
SomeArray[i++] = 3.14159;
SomeArray[i++] = "string";
}
