EDT Differences
EDT is another Digital text editor which runs on VMS and other systems.
Using the SET KEYPAD EDT command enables most of the EDT keypad functions,
but does NOT fully implement or emulate EDT.
The following is a list of differences between the EDT keypad in EVE and
real EDT. For hints on converting from EDT to EVE, see help on
EDT Conversion.
Keys defined differently from real EDT
--------------------------------------
PF1 GOLD. Setting the EDT keypad makes PF1 the GOLD key,
overriding any current definition of PF1. However, if you
set a different key as GOLD, the EDT keypad uses your GOLD
key without redefining PF1. The EDT keypad also defines
the EVE default GOLD key sequences, such as GOLD-FIND. See
help on Gold Keys.
GOLD-PF2 HELP KEYS. Displays a list of all defined keys.
KP1 MOVE BY WORD. Uses slightly different word boundaries from
real EDT. In EVE, a "word" includes the trailing white
space (spaces or tabs).
GOLD-KP7 DO. Enters an EVE command. EVE does not support or emulate
EDT line-mode or "nokeypad" commands.
GOLD-KP8 FILL. Reformats the current paragraph, range, or box. If
you want the key to fill only a range or box, redefine
GOLD-KP8 as FILL RANGE. Note that EVE paragraph boundaries
are different (see help on FILL).
ENTER RETURN. Terminates a command or starts a new line. You can
redefine ENTER, but cannot redefine RETURN or CTRL/M.
CTRL/C Usually halts an operation, such as a repeat or global
replace. However, if you are using keystroke journaling
(instead of buffer-change journaling), CTRL/C is not
recorded in the journal file. After using CTRL/C, you
should immediately exit, to save your edits. Otherwise, if
the system fails, you may not be able to recover your
work. This restriction does not apply with buffer-change
journaling, which is the EVE default.
CTRL/K LEARN. Starts a learn sequence, so you can bind several
keystrokes (commands, text, or both) to a single key.
CTRL/R REMEMBER. Ends a learn sequence and prompts you to press
the key you want to define for it.
CTRL/Z EXIT. Ends the editing session, typically writing out the
CTRL/D current buffer and asking whether to write out any other
F10 buffers if they were modified. If you want to emulate EDT-
style exit-to-line-mode, redefine CTRL/Z as DO. On ULTRIX
systems, EVE defines CTRL/D as EXIT. On VMS systems, EVE
does not define CTRL/D.
F12 EDT Backspace (Start Of Line).
CTRL/H
BACKSPACE
GOLD/0- When using the GOLD key to enter repeat counts, the
GOLD/9 CTRL/U key cannot be used to edit the number. Instead,
CTRL/U is repeated the number of times in the repeat
count. Also, EVE limits repeat counts to 5-digits less
than 32767.
Other differences from real EDT
-------------------------------
Cursor By default EVE uses a free cursor, which you can move
anywhere in the buffer regardless of the shape of your
text. To enable an EDT-style bound cursor, use SET
CURSOR BOUND. The EDT Character key (KP3) uses bound-
cursor motion even if the cursor is set to free.
Exiting EXIT creates a new file (or new version of a file) only
if you made changes to the buffer and have not yet
written it out. QUIT discards your edits, but if you
made changes to the buffer, EVE asks you to confirm
that you want to quit. If you have made no changes to
the buffer, EXIT is the same as QUIT. Also, on exiting
or quitting, if you changed attributes and have not
saved them, EVE asks if you want to save the changes---
see help on Attributes.
Input file When you invoke EVE, if you do not specify a file on
the command line, EVE creates an empty buffer named
MAIN, whereas real EDT prompts you to specify a file.
Also, EVE lets you use wildcards to specify the file---
for example, *.TXT. See DCL help on EDIT/TPU or see the
EVE Reference Manual
Journaling By default, EVE uses buffer-change journaling, which
creates a journal file for each text buffer and lets
you recover buffers individually and even from
different editing sessions. You can use keystroke
journaling and recovery, similar to that in EDT. See
help on Journal Files.
Mode Some commands or keys depend on the mode of the buffer
---insert or overstrike---for example, the EDT Delete
Character and EDT SpecIns keys. For a list of these
commands and keys, see help on CHANGE MODE.
Paste buffer Commands or keys to copy, cut, and paste text use
either the INSERT HERE buffer or DECwindows clipboard,
depending on your setting---see help on SET CLIPBOARD.
Scrolling SET SCROLL MARGINS correspondes to SET CURSOR in real
EDT, except EVE scroll margins are measured fronm the
top and the bottom respectively. For example, with a
24-line screen (21-line main window), SET SCROLL
MARGINS 5 6 is equivalent to SET CURSOR 5:15 in real
EDT. Default settings are 0 0 (scrolling begins when
you move past the top or bottom of the window).
Searches Searches follow EVE rules for case sensitivity and
direction (see help on FIND). Because EVE does not
treat RETURN and ENTER differently, as EDT does, search
strings cannot contain a carriage return. However, you
can use WILDCARD FIND for these searches, or use SET
FIND WHITESPACE to enable searching across line breaks.
Selections Commands or keys that work on a select range or found
range also work on a box. For example, you can use BOX
SELECT and the EDT ChngCase key. See help on Ranges And
Boxes.
Shift right SHIFT RIGHT and SHIFT LEFT move the window right and
relative to the buffer; whereas the EDT "nokeypad"
commands SHL and SHR move the buffer relative to the
window. Thus, in EVE, the command SHIFT RIGHT 8 is
equivalent to SHL in EDT---column 9 of your text
appears in the leftmost column of the screen.
Startup file At startup, EVE tries to execute an initialization file
named EVE$INIT.EVE, looking first in your current,
default directory and then, if necessary, in your
SYS$LOGIN directory. This corresonds to using an
EDTINI.EDT file with real EDT. For more information,
see help on Initialization Files.
Features NOT implemented in EVE
-------------------------------
o GOLD-key equivalents for control keys. For example, GOLD-U and
GOLD-Z are not defined, although CTRL/U and CTRL/Z are defined.
o Keys for tab adjustments. To change tab stops, use SET TABS or
define a key for the WPS Ruler key. See help on EDT Conversion.
