This is a problem when you are attempting to design a stack for people who have only a vague idea of what a file **is**, much less where it lives. It sure would be handy to be able to code a script something like: if FExists(fname) then --do file stuff here endif or: if VExists(volume_name) and FExists(volume_name&":"&path&":"&fname) then --ditto above else beep answer "You must mount the volume" && volume_name endif That's my 3.295 cents worth. |Standard Disclaimer |Tom Johnson |tomj@oakhill.UUCP
