VMS Help DEASSIGN, /QUEUE, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  $ ASSIGN/QUEUE LPA0  ASTER
     .
     .
     .
  $ DEASSIGN/QUEUE  ASTER
  $ ASSIGN/MERGE LPB0  ASTER

      The ASSIGN/QUEUE command in this example associates the logical
      queue ASTER with the print queue LPA0. Later, you deassign the
      logical queue with the DEASSIGN/QUEUE command. The ASSIGN/MERGE
      command reassigns the jobs from ASTER to the print queue LPB0.
