Parameter

display-device

   Specifies a logical name for the workstation display you are
   creating or modifying. If you are directing application output
   to multiple workstation displays, you can use different logical
   names to point to each display. If you do not specify a display-
   device parameter, the logical name DECW$DISPLAY is used. This
   means that, by default, application output will be displayed on
   the workstation display device referred to by DECW$DISPLAY.

   By entering the command SHOW DISPLAY, you can see the default
   workstation node where applications will be displayed, as well as
   related device, screen, and transport information.

   If you specified your own logical name in the SET DISPLAY/CREATE
   command, include that logical name in the SHOW DISPLAY command.
