Or perhaps it separates the half-elves from the hobgoblins. Hard-and-fast rules are seldom valid in stylistic questions. There's nothing wrong with having a prefix like "evt" or "on" or whatever; there's also nothing wrong with a naming convention of PB_Open_Click (PB for "PushButton" (which is what that GUI toolkit called them), Open being what the button does, and Click is the event being handled - that's the VX-REXX convention). Or having no specific event handler and going straight to your "pick_record" function; that's fine too, especially if you have multiple entry-points to that. Frederic, you'll get a lot of advice on this list, but treat it as just that - advice. There are very few actual rules; read what people say and then make your own choices. ChrisA
