My problem is that I'm getting some 'Stack overfault' in module -file name- at 0002:000E. Choose close. -file name- will close.
I'm using turboc++ 4.5.

These variables vill be created on stack. There is 15 000 integers. Stack just isn't lagre enough to hold it.
What do you need is to learn about dynamic memory allocation.
