I have ported a wave editor program to the amiga and found that the 
default stack of 4000 is too small. I tried using a system call in
the program to automatically set the stack, but it seems to fail.
Anybody know why this is, or how it can be done? 

#include <stdio.h>
#include <stdlib.h>

void main(void) {

printf("setting stack to 8192\n");
system("stack 8192");
system("stack");
}

the second call to stack with no argument returns the current stack
size: 4000. 

Thanks for any help,
