USREXIT4 User Exit

Use the USREXIT4 user exit to create accounting records to charge for tape mounts. This exit is called after the successful attach of the tape drive to the user ID. Use the exit to perform other post-mount functions. For instance, it can send information to another system because the TMC record passed to it has been updated to account for the current mount.

The exit must be written in assembler and should be reusable each time it is called. Do not modify the fields passed to the exit.

Because this exit creates accounting records with Diagnose X‘4C’, be sure the CA VM:Tape user ID has an ACCT statement in its directory entry.
