Hi, Does anybody out there know if I can alter the stack size (increase it to be specific) in Turbo C? And if yes, how can it be done? I got a stack overflow error in my program (compiled using small model) and after I flipped through all the manuals, I still cannot find anything that allow me to change the stack size (there is a global variable called _stklen, but it doesn't mention exactly how it is used). I CANNOT use anything higher than small model since I will have a memory allocation error (insufficient memory). BTW, I am using Turbo C version 1.5. Any suggestion and advises are welcome.

To change the stacklength, it is very easy: just say
_stklen = (num of bytes desired) in your program.
example: _stklen = 48000;
NOTE: I think it is required to set it globally, not locally.
Also, I did it in 2.0, not 1.5.

This must be done with a global initializer (i.e. at compile time) since it is used by the startup code (before main() ). I used this to force a very small stack in a program that did little more than shell out to another program, to stop it wasting 64K. It was necessary to set _heaplen to something small too. I think the heap length is set to 64K - data length - _stklen otherwise (for small model TC 2.0). For details, see the source file C0.ASM.
