DECwindows Differences

  You can use EVE on a workstation or on character-cell terminals. On
  workstations, you can use EVE in the Motif windowing environments. To
  invoke EVE with the DECwindows interface, use the following DCL command:

     $ EDIT/TPU/DISPLAY=DECWINDOWS

  Generally, EVE commands work the same in either environment. Here is a
  list of features and restrictions when you use EVE on DECwindows:

     Features        Usage on DECwindows
     ----------------------------------------------------------------------
     Clipboard       You can enable the DECwindows clipboard for copying,
                     cutting, and pasting, so you can transfer text between
                     EVE and other DECwindows applications. See help on SET
                     CLIPBOARD.

     Function keys   You can define shifted function keys, such as
                     SHIFT/FIND. SET FUNCTION KEYS MOTIF defines several
                     keys common to Motif applications.

     ALT key         You can define ALT key combinations, such as ALT/Z or
                     ALT/TAB. On DECwindows, the COMPOSE CHARACTER key is
                     the ALT key on older keyboards; to enter a compose
                     character sequence, use ALT/SPACE. Some newer keyboards
                     have a separate ALT key.

     Menus           You can execute commands by using pull-down and pop-up
                     menus (see help on Menus). To add or delete menu items,
                     choose Extend Menu from the Customize menu or use
                     DEFINE MENU ENTRY and UNDEFINE MENU ENTRY commands.

     Dialog boxes    Menu items that require additional information, such as
                     a file name, search string, or other parameter, display
                     a dialog box for entering the information. See help on
                     Dialog boxes.

     Quick Copy      You can use mouse buttons to copy or move text from EVE
                     to another DECwindows application or conversely. See
                     help on Quick Copy.

     Scroll bars     You can use scroll bars to scroll the buffer vertically
                     or horizontally. See help on Scroll Bars.

     Selecting       You can select text by clicking or dragging M1 (see
                     help on SELECT). Editing operations can use a selection
                     in another DECwindows application or a selection within
                     EVE. For example, you can select a file name in another
                     DECwindows application and then use OPEN SELECTED in
                     EVE to edit that file.

     Status line     Clicking M1 on a status line indicator toggles the
                     respective setting---for example, to change the
                     direction from Forward to Reverse or to change the mode
                     from Insert to Overstrike. See help on Status Line.

  Restrictions with the DECwindows interface

     o  You cannot use keystroke journaling on DECwindows. However, you can
        use buffer-change journaling, which is the EVE default. See help on
        Journal Files.

     o  You cannot use the ATTACH and SPAWN commands on DECwindows. However,
        if you run several DECwindows applications concurrently, you may not
        need to use subprocesses. However, you can use the DCL command which
        creates a subprocess differently from SPAWN and SPELL.

     o  WPS keys do not use the DECwindows clipboard. For example, the WPS
        Cut key uses the INSERT HERE buffer or a WPS-style alternate paste
        buffer, whereas the CUT command uses the clipboard or the INSERT
        HERE buffer, depending on your setting.

     o  Mouse operations are not recorded in a LEARN sequence.
