    You could try making a pointer and starting it at a position, say 0x0100, the starting point for .COM applications. You could continually increment this pointer, incrementing a counter variable for each location that the program is allowed to access. I'm not sure exactly how well this would work though, you'd likely crash the program trying to access a memory location outside of the correct segment, but the other two answers covered the best options.

    I think there was a function to find the number of bytes of free memory a computer has, but I don't remember it. It might be part of the Windows API.
