$CLEAR_SYSTEM_EVENT_(Alpha_and_Integrity_servers)

   Removes one or more notification requests previously established
   by a call to $SET_SYSTEM_EVENT.

   This service does not allow you to specify a handle and an
   event. You must pass a zero as one of these parameters. You can
   either clear by handle or request that all events for the user be
   cleared.
