Hi again,

Thanks for all your help.

I got it to work but I dont know how exactly. It was not the compatability thing tried win95, and win 2000. no joy. Reboot had no effect, re installing MC Studio had no effect. Also it was not a memory issue, system resource logging proved that.

I saved the file on the c drive & compiled from there using MPASM, and it worked, but I have problems with MPASM, so I unchecked use MPASM, and it worked.

So I then saved the bas file on the server, which has a very long file extension tree, with all the same settings as before, and bingo.

Very confused about what was wrong, but at least it works now.

Again thanks for your help
Regards
Bob...
