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

  $ SHOW DISPLAY
    Device:     WSA1:
    Node:       0
    Transport:  LOCAL
    Server:     0
    Screen:     0

  $ SET DISPLAY/CREATE/NODE=ZEPHYR
  $ SHOW DISPLAY
    Device:     WSA2:
    Node:       ZEPHYR
    Transport:  DECNET
    Server:     0
    Screen:     0
  $ SPAWN/NOWAIT/INPUT=NL: RUN SYS$SYSTEM:DECW$CLOCK

      In this example, you are logged in to your workstation, here
      referred to as node 0. (0 is the standard shorthand notation
      for representing your node.) You want to run the DECwindows
      Clock on your workstation and display it on another node,
      ZEPHYR.

      Assuming you are authorized to display applications on ZEPHYR,
      you redirect the application's output to ZEPHYR with the SET
      DISPLAY command and enter the SHOW DISPLAY command to verify
      the location of the redirected display. You then run Clock.
      Note that a new workstation display device, WSA2, is created
      when you enter the SET DISPLAY/CREATE command.
