VMS Help EDIT, /TPU, /DISPLAY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  /DISPLAY[={CHARACTER_CELL (default) | DECWINDOWS | MOTIF}]
  /NODISPLAY

  Determines the type of screen display, if any.  /DISPLAY is the same
  as /INTERFACE.

  For example, the following command invokes DECTPU with the Motif
  DECwindows interface:

     $ EDIT/TPU /DISPLAY=DECWINDOWS

  Then, if DECwindows Motif is available, DECTPU displays the editing
  session in a separate window on your workstation screen and enables
  DECwindows features---for example, the EVE screen layout then
  includes a menu bar and scroll bars, and you can use M1 to move the
  cursor and select text.  If DECwindows is not available, DECTPU works
  as if on a character-cell terminal.  For information about using EVE
  on DECwindows, use the online help in EVE and read the topic called
  DECwindows Differences.

  To specify your preferred display, you can define the logical name
  TPU$DISPLAY_MANAGER as CHARACTER_CELL, DECWINDOWS, or MOTIF.

  Use /NODISPLAY for batch jobs or when you are using an unsupported
  terminal.  For batch jobs, you typically use a DECTPU command file or
  EVE initialization file, as in the following example, which uses a
  command file named BATCH.TPU:

     EDIT/TPU /NODISPLAY /COMMAND=batch

  This batch file should comprise a complete editing session, including
  EXIT or QUIT.  Note that some EVE commands cannot be used in batch
  because they prompt for a key press or other interactive response.
