Thanks Alan, we can certainly give that a try.. But... I assumed (there is
that problem word) that if we mounted the tape cartridge, did a "TAPE REW"
then a "TAPE DUMP * * A" that it would wipe out any standard label on the
cartridge... that it would become a no-label tape no matter what it was
before...
As far as I know (!), he has no tape management software or anything else
that would be monitoring or looking for standard labels.
I will mention the SL issue to him though, just in case....
Thanks
Mike

Has he used DDR, MOVEFILE, DITTO, PIPE, whatever to simply look at the
tape? Perhaps it has a standard label on it, something easily handled by
z/OS. If so, TAPE FSF to skip the label, then TAPE LOAD.
