Jack,
Yes, the program compiles but then I get a windows error message when
I run it. It runs fine when I use gcc on the sun workstation. I guess I'll try dynamic memory allocation as you suggested, but I can't understand why I have a problem running the program on the PC but
not on the Sun. Thanks for your help.

Not to sure what you mean by GCC won't run? Does the program compile and then seg fault when you run it?
I ran into a similar problem a few months ago (google for my name and you'll see the posts).
Yes there is a limit to the size of your arrays can be when put on the stack.
try instead
double *A; A = malloc(500000*sizeof(double));
this should declare the array in the main bulk of your memory. Then access A as per usual.

I installed MinGw on a pentiuim 4m laptop with 1G of RAM. Apparently GCC won't run when I make my array size too big. Is there some limit on the array size and is there any way for me to set it up so I can have large arrays, e.g., A[500000]. Thanks.
