/SYMBOLS (Alpha/Integrity servers only)

    Defines one or more global DCL symbols for each property
    displayed by the SHOW DISPLAY command. You can then use these
    property symbols in DCL command procedures.

    Each global symbol name follows the form:

    DECW$DISPLAY_name

    The following are the symbols for predefined properties:

       DECW$DISPLAY_NODE
       DECW$DISPLAY_TRANSPORT
       DECW$DISPLAY_SCREEN
       DECW$DISPLAY_SERVER
       DECW$DISPLAY_XAUTH

    Note that symbols for user-defined properties have a double
    underscore in the name. For example, the user-defined symbol
    for the value DISK$USER:[JONES] would be defined as follows:

    $ SHOW SYMBOL DECW$DISPLAY*

      DECW$DISPLAY_NODE == "101.124.99.119"
      DECW$DISPLAY_SCREEN == "0"
      DECW$DISPLAY_SERVER == "0"
      DECW$DISPLAY_TRANSPORT == "TCPIP"
      DECW$DISPLAY_XAUTH == "DISK$USER:[SMITH]SERVER1.DECW$XAUTH"
      DECW$DISPLAY__JONES == "DISK$USER:[JONES]"

    If a symbol name or value exceeds or violates any DCL limits or
    naming conventions, the symbol is not set and an error message is
    displayed.

    If the display device uses a proxy server, the symbols
    DECW$DISPLAY_NODE, DECW$DISPLAY_TRANSPORT, and DECW$DISPLAY_
    SERVER reflect values associated with the proxy server and not
    the X display server.
