/sys$common/syshlp/helplib.hlb ASSIGN, /MERGE, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  $ STOP/QUEUE/NEXT LPB0
  $ STOP/QUEUE/REQUEUE=LPA0 LPB0
  $ ASSIGN/MERGE LPA0 LPB0

      In this example, the STOP/QUEUE/NEXT command prevents another
      job from executing on queue LPB0. The STOP/QUEUE/REQUEUE
      command requeues the current job running on LPB0 to the target
      queue LPA0. The ASSIGN/MERGE command removes the remaining jobs
      from the LPB0 printer queue and places them in the LPA0 printer
      queue.
