Scratching Tapes

Tapes are logically changed from nonscratch to scratch status in any of the following ways:

Automatically during the TRS run.
Manually by changing SCRATCH=NO to SCRATCH=YES on the Update screen.
Manually by using the UPV command and specifying SCRATCH=YES. If there is more than one data set on the volume, you must also specify CDS=nnnn, where nnnn is the file sequence number (FILESEQ) of the data set. (To see the file sequence number, use the DV command.)
By specifying DISP=(OLD,DELETE) in the JCL, if TLMSIPO option DISP=YES is specified.
