/INTERFACE

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

 Same as /DISPLAY---determines the interface or screen display you
 want.  For example, the following command invokes TPU with the
 DECwindows Motif interface:

    $ EDIT/TPU /INTERFACE=DECWINDOWS

 Then, if DECwindows Motif is available, TPU displays the editing
 session in a separate window on your workstation screen and enables
 DECwindows features---for example, the EVE screen layout includes a
 menu bar and scroll bars, and you can use M1 to move the cursor and
 select text.  If DECwindows Motif is not available, TPU 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.
