REBOOT

   REBOOT automatically shuts down and reboots the system, thus
   installing the new parameter values. To install 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.

   REBOOT requires the SETPRV privilege.
