Have written the code already in perl if you want a copy? Runs daily, figures 
out what vtl volumes have been returned to scratch in the last 24 hours and 
labels accordingly.

Makes sense to me, and both serve my purpose.  They're virtually
equivalent today, but on older tapes I'll bet that would have made a
difference.  Since both seem to exit with status code 23 rather than 0
on normal labels, and since -erase adds output, I'm just going to let it

I was kind of hoping that -erase would be similar to Networker's relabel
command, which will erase a volume without confirmation only if it
already has the same internal label.  You can't accidentally change the
equivalent of the RVSN that way.  But no such luck.

Thanks for the info.
