EDDY (TM)
REVISION HISTORY
Since the first public release of EDDY, many intermediate versions have
been produced, but they had very limited distribution. There does not
seem to be any useful purpose in detailing the history of all of them.
This document describes functionality changes other than minor bug
fixes. Changes in the current version of EDDY are described first.
Changes to versions prior to 5.01 have been deleted from this file, as
there seems to be little interest in ancient history among the user
base. If you have one of the older versions, and feel that you need
this information, I'll be glad to send it to you. Just ask.
Version 7a (changes since 6c2)
==============================
1. EDDY's "Disk Jockey" functions (see Section 21 of EDDY.DOC) now work
with any size disk (including RAM disks). Earlier versions were
restricted to disks of 32 megabytes or less.
2. With the cursor on the '..' entry in the display, and display
sequence is...
...not inverted: pressing [home] moves to next higher directory
...inverted: pressing [end] moves to next higher directory
just as though you had pressed [f3].
3. In addition to interrupting repeating commands such as [^f], [^F5],
etc., pressing [^c] will also terminate a "where's that file?" scan,
as well as the directory scanning process that calculates the net
sizes of files involved in an impending update.
4. If there are no changes pending, pressing [Enter] will have the same
effect as pressing [F3] if you are positioned on a file, directory
or "drive" entry in the display; i.e., you will LOOK at that entry.
On other display lines, you'll get the usual "Nothing to update"
message. If you don't like this use of [Enter], you may customize
EDDY accordingly; see Section 24.3.4 of EDDY.DOC. [Enter] still
initiates an UPDATE if changes are pending.
5. When LOOKing at RAM, any directory entries that are found there may
be displayed in EDIT-mode ("DIR") format. Just as when LOOKing at a
disk, move the directory data to the top of the screen, and press
[Alt+d].
6. Some administrivia: 1) EDDY now (gently) reminds you if you are
using an unregistered copy. Upon registering, you will receive the
latest version, personally registered to you. 2) After more than
two years of significant changes and the ravages of inflation,
EDDY's registration fee is increased to $25.00.
Version 6c2 (changes since 6c)
==============================
1. If you press and hold down the [Scroll] key, all processing stops
until you release the key.
2. [NumLock] state (ON/OFF) is always ignored by EDDY -- i.e., treated
as OFF, unless [NumLock] is pressed while EDDY is running. Once it
has been pressed, its state is recognized and treated accordingly.
3. Disk-image copying, formerly referred to as "disk-to-file", can now
be done from EDIT mode, by pressing [Alt+F5]. No need to go to LOOK
mode, mark all clusters, and then copy.
The no. of bytes of control information prefixed to a disk-image
file has increased, from 4 to 6. However, if you have backup disks
created with earlier versions of EDDY, these may still be used; EDDY
recognizes the difference and acts appropriately.
4. When LOOKing at a disk (the "Drive" line in the display), you may
"mark" clusters to be copied even though you have not selected a
target directory previously. If there is no target, EDDY will ask
for one, without requiring an exit to EDIT mode.
5. [BackSpace] may be used to terminate a repeating operation, as well
as [^c]. This is to avoid traumatic experiences for long-time EDDY
users who have problems adjusting to change no. 7 of version 6b.
6. If you go to PATCH immediately after a successful FIND, the patching
cursor will be placed on the character at the start of the "found"
string. The cursor will be in the same mode (hex/ASCII) as the mode
used to enter the search string when you did the FIND.
If you press any key except [F4] after the FIND, the cursor will be
placed on the first character of the display if you subsequently do
press [F4] to PATCH.
Version 6c (changes since 6b2)
==============================
1. If tree directory selection method is used, and an EDDYTREE file
exists, the file will be updated automatically if it is found to be
inaccurate.
2. If files are excluded from the working directory display because
attribute or timestamp filters are in use, an asterisk will appear
next to the file count field in the heading.
3. Numeric option /3 is introduced. If this option is used, the
modules needed for updating and for LOOK mode operation will be
loaded from EDDY.AUX when the program starts, and will be locked in
memory until EDDY terminates. This option is primarily useful for
running EDDY from a floppy. Using /3 ensures that EDDY's basic
functionality is always available, even if the diskette containing
EDDY.AUX is removed.
4. When comparing files -- [Alt+Shift+F3] -- the values of the bytes
where differences are found are now displayed along with the file
offset.
Version 6b2 (changes since 6b)
==============================
1. Point-n-shoot and the DOS Gateway features sometimes caused systems
which have no expanded memory to "hang", requiring a red-button
reboot. This is fixed.
Version 6b (changes since 6a)
=============================
1. Directories may be selected from a tree diagram, rather than typing
in the directory names. This involves lots of new functions and
commands; certainly too much to describe here. See Sections 5.1 -
5.3 of EDDY.DOC for more information.
2. Empty (zero-length) files may be copied and moved.
3. After executing EDDY interactively (rather than in batch mode),
ERRORLEVEL will always be set to zero.
4. Option /L means "Set top of LIST to current cursor position" (for
use with repeating commands. This was formerly option /T.
5. When customizing, a list of customizable features is provided for
review just before the new EDDY.COM is written.
6. Mouse sensitivity is adjustable - press [Alt+Shift+m].
7. [^c] is used to terminate a repeating command - formerly [BackSpace].
8. When building commands for "point-n-shoot' (EDDY.USE file or [F8]),
the extension for the program file involved is no longer required.
9. The "speed search" facility for directories and filenames has been
modified slightly. It is described in EDDY.DOC Section 4.1.
Version 6a (changes since 5.53)
=================================
1. With this release, EDDY begins his move into the modern world.
There is now support for mice (Microsoft-compatible variety, since
that's all I've got to test with). Details are in Section 2.1.2 of
EDDY.DOC.
2. Another major addition to user-friendliness (and without which a
mouse wouldn't be all that useful) is pull-down menus. Menus are
described in Section 2.2.2 of EDDY.DOC.
In the following paragraphs, you may note that some command keys are
now used in different places with different meanings. In the past,
I've tried to avoid this, to maintain consistency and reduce
complexity. With the addition of the menus, however, there's not
nearly so much to remember in order to use EDDY efficiently.
