USREXIT7 User Exit (Tape Positioning User Exit)

Use the USREXIT7 user exit to rewind and position the tape, after the VOL1 label, on the CA VM:Tape service virtual machine just before the drive is attached to the user ID. Use this exit to prevent users from overwriting the VOL1 label.

The exit can be written in either REXX or assembler and must be reusable each time it is called.
