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.
