USREXIT1 User Exit

Use the USREXIT1 user exit to provide extra security for foreign mounts. For example, use the exit to disallow users who may attempt to mount tapes for which they are not authorized by using the FOREIGN option on the MOUNT command. The exit may accept, reject, or force the foreign mount to be a read / only mount. The exit is not called for library or scratch mounts; therefore, it is not necessary for the exit to verify that the volser is not in the TMC.

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.

This exit is not called if the user is authorized to mount the volser using a rule in CA VM:Secure.
