Well, you could increase your stack size.  To do this in Turbo C++
version 3.0 for DOS (I'll bet it's the same, though, for all versions
of Turbo C), you have to set the global variable _stklen, declared in 
DOS.H, to a new value.  For instance,

/*-----------------------------------*/
#include <stdio.h>
#include <dos.h>


extern unsigned _stklen = 543210U;

int main(void)
{
   printf("The stack size is %u\n", _stklen);
   return 0;
}
/*-----------------------------------*/

That should do it.  If you increase your stack to the size I used
above, and you still overflows, then you may want to check your code
for some infinite loops or other things of that nature.

There are three ways to eliminate a stack overflow problem.

1)  Make more of the data static, either via the static keyword, or moving
it outside the scope of the function.

2)  Reduce the number of recursions.  If your program doesn't have recursions,
    this probably won't help.

3)  Increase the stack size.  See Turbo's Library Reference (global variable
    section) for more information.

Note unsigned has range from 0 to 0xFFFF(=65535U), don't try use
bigger values because compiler will truncate high-order bits. 
Also note not every memory model allows 64kB stack.
