USREXIT5 User Exit

Use the USREXIT5 user exit to request that a data security erase (DSE), which erases all data from the tape, be performed against the volser before the tape is given to the user. Use this user exit to prevent unauthorized users from gaining access to data by using the specific scratch mount capability. This exit is called for all specific scratch and scratch mounts that have an access type of read/write after the mount has been accepted as valid and the TMC has been updated to reflect the volser as a saved tape.

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, except for the flag field.
