    1.MAIL> SHOW QUEUE
      Your default print queue is SYS$PRINT
      MAIL> SET QUEUE LMNO$PRINT
      Your default print queue is LMNO$PRINT.
      MAIL> 4
      MAIL> PRINT
      MAIL> exit
      Job MAIL (queue LMNO$PRINT, entry 22) started on LMNO$PRINT

      MAIL> SET NOQUEUE
      Your default print queue is SYS$PRINT.

      This example shows how to set your default print queue to
      LMNO$PRINT and send a message to the new default queue. The
      SET NOQUEUE command clears the previously defined queue and
      sets the queue to SYS$PRINT, the default.
