Why, as long as it's not hard coded?
Years ago I was involved with a GDG setup where the files were
originally allocated on DASD and after a designated number of
generations, the older ones where copied to tape with the GxxxxV00
changed to Gxxxxv01. Thus you could have 21 generations with only the
most recent 7 being on DASD (ie: -7 to -20 were tape). This was done
by creating the tape copies as absolute generation named and this
replaced the DASD reference in the catalog. The same thing could be
done by moving a DASD file to another volume (with the V01 name).
