> how can I delete only one volume in the VOLHIST ?

I've bemoaned this deficiency myself.  I do a DB Backup every n
days, with at least one incremental DB Backup each day in between
the full backups.  Once I have a new full, I'd like to discard my
incremental volhist entries (to free up limited disk; incrementals
normally to disk), but that means older full DB Backup entries are
discarded.

cheers, wayne
