If so, you could be attempting to catalog a name that already exists. Not a problem for most generation datasets, but I would guess that someone would trip over this someday. Especially if z/OS lasts another 50 years ;-)
Also, what is the significance of the V00 part of the qualifier? I was always led to believe that it was a vestige of something that was never implemented. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
