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 -

The directory of a PDS is not VB. It is
RECFM=F,LRECL=256,BLKSIZE=256,KEYLEN=8. You can ignore the key, if you
want. You must read all 256 bytes and "deblock" the "logical records"
yourself. They are not compatable with RECFM=VB, but they are "close".
"Close" only counts in horse shoes and nuclear weapons.
I have code, which I got from somewhere, that I can share. I also sure
that there is some available on http://cbttape.org somewhere, but I
don't know where.
