Hi John, Yeah... I know the directory portion isn't VB. But, the program doesn't know that.. it "thinks" it's simply been given the name of a sequential VB file that it wants to process.... So - it stumbles blindly into the directory - and *whamo* - gets this "bad" data. So - I suppose - what's the best way to ask "Hey - is this at all a reasonable thing to be trying a VB-read on?" - Thanks - - Dave Rivers - McKown, John wrote: > > The directory of a PDS is not VB.
