So far research has revealed that you can change a setting in Reg that controls upper and lower case when saving. But what I need is a way to insure that at least the first four letters stay upper case. Of course I need to do this from the app and not change a reg setting.

Sorry, John, but I'm failling to follow you. As far as I can experiment, FCREATE() honors the filename case (such as in FCREATE("UPPERCASE.TXT"), FCREATE("lowercase.txt") or FCREATE("MixedCase.Txt")). So why the need to change it afterwards? I even tried to upload each of these files to a UNIX server (via FTP) and they came out nicely as expected...
