    1.$ SHOW DISPLAY
        Device:     WSA1: [super]
        Node:       0
        Transport:  LOCAL
        Server:     0
        Screen:     0

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

      $ SET DISPLAY/DELETE

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

      In this example, you are logged in to your workstation (device
      WSA1:), 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 workstation, ZEPHYR.

      Assuming you are authorized to display applications on ZEPHYR,
      you redirect the application's output to ZEPHYR with the SET
      DISPLAY command. The device created on ZEPHYR is an executive-
      mode device. You enter the SHOW DISPLAY command to verify the
      location of the redirected display. You then run Clock. When
      you finish running Clock, you disable the redirected display
      by entering the SET DISPLAY/DELETE command. Finally, you
      enter the SHOW DISPLAY command to verify that any applications
      subsequently run on your node will also be displayed there.

      Note that a new workstation display device, WSA2, is created
      when you enter the SET DISPLAY/CREATE command. When you cancel
      the redirected display with the SET DISPLAY/DELETE command,
      application output is once again displayed on the workstation
      display device referred to by WSA1.

    2.$ SET DISPLAY/CREATE/NODE=FLOPSY RABBIT
      $ SHOW DISPLAY RABBIT

       Device:    WSA2:  [super]
       Node:      FLOPSY
       Transport: DECNET
       Server:    0
       Screen:    0

      $ RUN/DETACHED/OUTPUT=WSA2: SYS$SYSTEM:DECW$CLOCK

      $ SET DISPLAY/CREATE/NODE=ZEPHYR ZNODE
      $ SHOW DISPLAY ZNODE

       Device:    WSA3:  [super]
       Node:      ZEPHYR
       Transport: DECNET
       Server:    0
       Screen:    0

      $ RUN/DETACHED/OUTPUT=WSA3: SYS$SYSTEM:DECW$CALENDAR

      $ RUN SYS$SYSTEM:DECW$BOOKREADER
      $ SHOW DISPLAY

       Device:    WSA1:  [super]
       Node:      0
       Transport: LOCAL
       Server:    0
       Screen:    0

      In this example, you are logged in to your node (device WSA1:),
      and want to direct the output from applications to several
      workstation displays in the same session. By specifying
      different logical names in the SET DISPLAY command, you
      can redirect the output without changing the logical name
      definition for DECW$DISPLAY. This allows you to display the
      output from most applications on your default display but
      occasionally display output on another workstation. You can
      also continue to run and display applications on your node. In
      this example, Clock is displayed on node FLOPSY, Calendar is
      displayed on node ZEPHYR, and Bookreader is displayed on your
      workstation.

      Note that to run your applications with the DCL command
      RUN/DETACHED, you must use the device name that equates to the
      logical display device name you specified in the SET DISPLAY
      command. Use the SHOW DISPLAY command to obtain this device
      name.

    3.$ SET DISPLAY/CREATE/GENERATE=TRUSTED-
      _$ /XAUTHORITY=XAUTHORITY_TEMP/NODE=ZEPHYR
      $ PIPE SHOW DISPLAY/EXTR | RSH FLOPSY "XAUTH NMERGE SYS$INPUT"
      $ SET HOST FLOPSY
      $ SET DISPLAY/NODE=ZEPHYR
      $ RUN SYS$SYSTEM:DECW$CLOCK

      In this example, you are logged into your workstation (WSA1:)
      and want to run the DECwindows Clock application on a remote
      node (FLOPSY) and display it on another workstation (ZEPHYR).
      Both systems are using Magic Cookie authorization to control
      access to the X display server.

      Assuming you are already authorized to connect to the server
      on node ZEPHYR, you create a display device that connects to
      ZEPHYR and generates a new authorization key. This key grants
      trusted connections to the server on ZEPHYR within 60 seconds
      of key generation. To restrict trusted access to the server,
      the key is stored in a new X authority file, XAUTHORITY_
      TEMP.DECW$XAUTH.

      The authorization key is then extracted and copied to FLOPSY,
      and merged with other entries in your X authority file on that
      system. You then set host to node FLOPSY and set display to
      node ZEPHYR. When you run the clock application from FLOPSY,
      it connects to the server on ZEPHYR and is allowed access as
      specified by the generated authorization key.

    4.$ SET DISPLAY/CREATE/VALUE=-
      _$ (NAME=DECW$SESSION_MANAGER,SET="tcpip/zephyr:9510")
      $ SHOW DISPLAY/SYMBOLS/ALL
          Device:    WSA23:  [super]
          Node:      0
          Transport: DECNET
          Server:    0
          Screen:    0

        User-defined values:

          "DECW$SESSION_MANAGER" = "tcpip/zephyr:9510"

      $ SHOW SYMBOL DECW$DISPLAY__DECW$SESSION_MANAGER
        DECW$DISPLAY__DECW$SESSION_MANAGER == "tcpip/zephyr:9510"

      $ SET DISPLAY UNTRUSTED/CREATE/XAUTHORITY=TEMP/GENERATE-
      _$ /VALUE=(NAME=DECW$SESSION_MANAGER,-)
      _$ SET="'DECW$DISPLAY__DECW$SESSION_MANAGER'"

      In this example, you create a display device, and set the
      DECW$SESSION_MANAGER property to the network address of a
      session manager on remote node ZEPHYR using port number 9510.
      The SHOW DISPLAY/SYMBOLS command then defines a DCL symbol for
      the port value. The symbol is then used to set the port value
      for a new display device.

    5.$ SET DISPLAY/CREATE/PROXY=GATEWY/NODE=hubbub.company.com-
      _$ /PMTRANSPORT=DECNET/NOLBXAUTHENTICATE/TRANSPORT=TCPIP

      $ SHOW DISPLAY
          Device:    WSA23:  [super]
          Node:      HUBBUB.COMPANY.COM
          Transport: TCPIP
          Server:    0
          Screen:    0

        Connection will use:
          LBX proxy on node:  gatewy.company.com
          Transport to proxy: TCPIP
          Server number:      63

      $ RUN SYS$SYSTEM:DECW$CLOCK

      In this example, you are logged into a local workstation
      (FLOPSY) and want to connect to an external host
      (hubbub.company.com), which is outside of your company's
      firewall. You use the proxy manager on a gateway host (GATEWY)
      to start the LBX proxy server, connect to the external host,
      and display the DECwindows Clock application.

      Note that DECnet is used within the local area network (LAN)
      to communicate to the proxy manager, and TCP/IP is used by
      the proxy server to communicate to the X display server on the
      external host. When using a managed proxy server, the proxy
      server chooses the transport for the client-to-proxy server
      connection.
