SHUTDOWN

   SHUTDOWN shuts down the system and awaits a manual reboot. To
   use the new system parameter values generated in the SETPARAMS
   phase, specify either SHUTDOWN or REBOOT as the end phase. You
   can define the logical name AGEN$SHUTDOWN_TIME (using the DCL
   command DEFINE) to specify the number of minutes before shutdown
   occurs.

   SHUTDOWN requires the SETPRV privilege.
