I have a ms prof basic legacy program with a lot of variables. I can edit the program ok under win 98, and can compile ok as well. But all subsequent win versions give me an "out of memory" message when I select open program. I am not very techie so if you can help, thanks. I am keeping a win 98 system running just to edit this program but would like to eliminate that system.

Well, my advice would be to try the Compatibility Mode options w/ the compiler. Outside of that, I'd rewrite it for a newer version of VB. I'd be more specific (actually, no, I wouldn't), but you don't even tell us the version of VB you're using, and I know VB 6 compiles under WinXP.
