I'm having a few problems with debug (c:\windows\command\debug.exe). Whenever I run a program I get an error at a memory location way ahead of where my program is running, despite the fact that I have put a 'q' (quit) at the end of my program. Any advice anyone??

Well, I don't really know what you mean, but maybe your program is writing to a location it's not supposed to, and debug is interpreting that as an error way ahead of where your program is running.

Look in your program and find out when it gives you this error, and disassemble that portion to see if you can find the problem.
