You could trying getting the FMT1DSCB for the data set and looking at the
organization.

Re: Reading Variable record with bad BDW/RDW?
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 -
