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 7c (changes since 7b)
=============================
1. Now you can register your copy of EDDY by credit card! Please see
details in EDDY.DOC, Section 26.2.1.
2. Directory sorting can now be made permanent. You can also arrange
your directories in any arbitrary sequence you wish. See Section 22
of EDDY.DOC.
3. Option /H has been added (or as some long-time users will realize,
reinstated). By default now, EDDY does not include files with
"hidden" or "system" attributes in the display. Using the attribute
filtering mechanism displays ONLY those files. If you want to show
all files together, use option /H.
4. When the DOS system files (IBMBIO.COM and IBMDOS.COM, or some such
name) are included in the display of the root directory, they will
be at the top, to emphasize their importance -- i.e., if you mess
with them, you probably won't be able to boot your system!
5. Disk-image copying and restoring are both used by pressing
[Shift+F5]. If the cursor is on the "Drive" line of the display,
disk-image copying is started; if it is on a file, disk-image
restoring is used (and the file is now tagged "Copy image", rather
than "Copy(!)" as previously).
6. If EDDY is started from a floppy, the necessary overlays to handle
UPDATE and LOOK/PATCH operations are pre-loaded automatically, so
that the diskette may be changed and that same drive may be used as
working or target directory if desired. Previously, you had to use
option /3 to do this.
7. You can set the date and time to all zeros (both, not separately).
If you do this, the timestamp will not be displayed at all when you
use the DOS "DIR" command. Useful to call attention to entries in
the "DIR" listing.
8. When you LOOK at a disk, the initial display will be the sector of
the current working directory, rather than the boot sector.
9. EDDY attempts to identify "compressed" or "extended" disks that are
produced by products such as Stacker (tm) or DoubleDisk (tm). Some
of the things (e.g., sector patching, directory moving) you can do
with EDDY are unsafe to do with these disks. If EDDY can't
automatically determine the disk type, you will be asked before
anything potentially unsafe is attempted.
10. In answer to requests from European users, the margins of EDDY.DOC
have been changed slightly, to accommodate printing on A4-size paper.
Version 7b (changes since 7a)
=============================
1. A number of bugs had crept in over time, having to do with incompat-
ibilities between DOS versions. These had made some of EDDY's
features (in some cases, ALL of EDDY's features) unusable with
versions earlier than DOS 3.2. These bugs have been resolved, and
EDDY should again be usable with DOS 2.0 and all later versions.
2. In recognition of the growing number of EDDY users who are not from
the USA, EDDY will display file timestamps in the format you choose.
If your system is set up (usually via the "COUNTRY=" command in
CONFIG.SYS) to use dates of the form "dd/mm/yy" or "yy-mm-dd",
rather than the USA-style "mm-dd-yy", EDDY will use that format.
3. EDDY's display has been made more helpful. More of the function key
uses are shown on the bottom line, and the area to the right of the
files display has some "boxes" showing more key uses; these boxes
may also be "clicked" on with a mouse to get the indicated action.
4. Redirection is supported for "Point-n-Shoot" and EDDY.USE commands.
5. The "Exit directory" functionality has been expanded, and renamed as
"Directory Recall". As before, [Shift+F10] selects the current
working directory as the directory that will become the default when
you quit EDDY. To acknowledge the selection, the message "Directory
recall set" is displayed. The new capability is that having set
directory recall, pressing [Shift+^F10] uses the selected directory
as the new working directory.
6. Editing a file's timestamp has no effect on the file's attributes.
Previously, timestamp edits turned on the "archive" attribute.
7. When a repeating command such as [^F5], [^F6], etc. is executed, a
message is displayed telling how many files have been tagged for the
corresponding action.
8. Some error and warning messages have been changed, but also more
thoroughly documented (Appendix C of EDDY.DOC). When these messages
are displayed, a reference to Appendix C also appears.
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, directory entries 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.
Overloading certain keys seems to simplify operations in some cases.
3. After an UPDATE, any files moved or deleted from the working
directory will be shown grouped together at the end of the directory
display, rather than in their original locations before the UPDATE.
If there are more files in the directory than can be displayed by
EDDY (currently, about 400), files deleted or moved will not be
shown; instead, additional files from the working directory will be
displayed.
4. Point-n-shoot capabilities are improved in 3 major ways:
a. When you select a .COM, .EXE or .BAT file to execute ([Alt+F9]),
you may edit the command line first, to add filenames, switches,
or whatever is appropriate for the file involved.
b. Commands from EDDY.USE ([Shift+F9]/[Shift+^F9]) may also be
edited before they are used.
c. You may specify a default command, which may be executed when
there is no command found in EDDY.USE for the current file, or
if you have no EDDY.USE file. The default command may be edited,
made permanent (by customizing EDDY), or executed directly (by
pressing [Shift+F8]).
5. You may UNDO the COPY, MOVE, DELETE and DESTROY commands without
affecting other changes that may be pending for the file. Just
press the key for the same command again; i.e., if a file is tagged
for COPY, and you decide not to COPY, press [F5] and the tagging
will disappear, but any other changes will remain.
6. When the copy/move confirmation window is displayed (as when the
file in the target is newer than the one in the working directory),
[Alt+a], [Alt+c] and [Alt+o] are accepted as valid responses.
7. After using the DOS Gateway - with [F9], [Alt+F9] or [Shift+F9] -
the working directory will be reprocessed to insure that any changes
made outside of EDDY will be reflected properly in the display.
8. You may tag a file for copy with TAB expansion and/or bit-stripping
directly, by pressing [Alt+number] or [Alt+b]. No need to tag the
file first by pressing [F5].
9. The treatment of the archive attribute for files copied has changed
slightly. If option /A is on, the archive attribute on the new copy
of the file will be the same as the original file. If option /A is
off, the archive setting depends on the type of disks involved:
a. Floppy to floppy - copy set same as original
b. Hard disk to hard disk - copy set same as original
c. Floppy to hard disk - archive attribute in copy turned off,
original unchanged
d. Hard disk to floppy - archive attribute in copy turned on,
original turned off
10. [Alt+r] from EDIT or LOOK modes displays a "FIND & REPLACE" dialog
box directly. Before, you first had to press [Alt+f], then [Alt+r].
11. When LOOKing at a text-format display with lines longer than 80
characters, moving to the left or right edge of the display may be
done by pressing [Home] or [End], respectively. [^Left] and
[^Right] are still available for this, as well.
12. Pressing [Home] twice in a row has the same effect as [^Home] -
i.e., in EDIT mode, the cursor moves to the top of the directory
display, and in LOOK the display moves to the start of the file.
Similarly, [End][End] is the same as [^End].
13. Pressing [s] in LOOK toggles [Up] and [Down] between their normal
scrolling speed of one-line-per-keypress and half-page-per-keypress.
A half page is defined by the number of text lines in the display,
not the physical lines available on your screen. Thus, the speed of
scrolling will vary, depending on the data you're LOOKing at.
14. In PATCH mode, press [Alt+a], to truncate a file after the cursor,
or [Alt+b], to truncate before the cursor. Previously, you pressed
[Alt+y] to truncate, and then answer the "Before or After" question.
You can still use [Alt+y], too.
15. With path string displays, such as those resulting from [Alt+w] or
[Alt+t], the displayed string may be edited before use.
16. The "pause" indicator for commands defined in EDDY.USE is changed.
It is now "|" (the DOS piping symbol) instead of a hyphen.
17. The HELP screens and menus have their own color attributes, not tied
to those used for other EDDY screens (but HELP colors are the same
as menu colors). These colors may be customized as desired.
18. Volume serial number display and update are now supported. Press
[^v] for these functions.
19. You may enter a FIND string containing all "?"s. This will match
with strings containing all LETTERS.
20. When a batch mode execution finishes, "ERRORLEVEL" will be set
according to the results - 0 for successful update, 255 for no
matching files, other values corresponding to DOS error codes.
21. The files making up the EDDY distribution package have been changed.
EDDYHELP.COM and EDDYLOOK.COM are now combined, along with the new
MENU functions and UPDATE processing, into the single EDDY.AUX file.
EDDY.HST, EDDY.WHY and EDDY.REG are now called EDDY_HST.DOC,
EDDY_WHY.DOC and EDDY_REG.DOC, respectively.
Version 5.53
============
1. Documentation update only, incorporating material relating to the
Association of Shareware Professionals (ASP).
Version 5.52 (changes since 5.49)
=================================
1. [Ctrl]-shifted letter keys are treated similarly in LOOK mode as
they are in EDIT, described in item 3, version 5.49, below. Note
that when entering data, as in PATCH or FIND, the [Ctrl]-shifted
letters enter their corresponding characters.
2. [Alt+S+p] sends a form feed to the printer.
3. [S+F7] and [S+^F7] are used for the "Destroy" and "Destroy ALL"
commands. Formerly, these commands used [F8] and [^F8]. [F8] now
reserved for future use.
Version 5.49 (changes since 5.45)
=================================
1. When calculating the net change in disk usage for the UPDATE
confirmation display, space used for directories is included
whether or not option /D is on. (Except with disks larger than
32 MB, for which this is not yet implemented.)
2. Read-only files may be patched without explicitly turning off the
read-only attribute first (after a warning and "yes" answer from
the keyboard).
3. Some users who use different keyboards at different times have
mentioned that they often hit [Ctrl] when they want [Alt] on the
AT-style "enhanced" keyboard. To minimize errors due to this
problem, in EDIT mode EDDY treats most [Ctrl]-shifted letter keys
the same as if the corresponding [Alt]-shifted key. Thus, either
[Alt+o] or [^o] can be used to change the option settings, [Alt+a]
or [^a] to set an attribute filter, etc.
Only four of the letter keys are not always treated this way: [^f],
[^w], [^n] and [^y]. [^f] always means "FIND in all files". [^w]
always means "Where's that file?". [^n] and [^y] set attributes IF
the cursor is in the attribute field; if not, [^n] sorts the
directory by name (like [Alt+n]) and [^y] has no effect (like
[Alt+y]).
4. Option /W is used only from the command line. To initiate "Where's
that file?" searching within EDDY, only [^w] is used.
Version 5.45 (changes since 5.44)
=================================
1. When EDDY asks for a "y/n" response, again pressing the same key
that produced the message is treated as "yes".
2. The "seconds" field of a file's timestamp may be edited. (But only
even #s may be entered - a DOS limitation.)
3. [Alt+p], pressed when you are in EDIT mode, prints the directory.
If you press [Alt+p] when EDDY is waiting for you to confirm that
you want to UPDATE (i.e., after you have pressed [Enter]), all
update actions will be printed as they occur. Pressing [Alt+p]
again turns printing off.
Version 5.44 (changes since 5.42)
=================================
1. Bit stripping now works with hex-format displays.
2. When LOOKing at a file in hex format, you may select the hex portion
of the display to be in words (as opposed to the normal bytes) by
pressing [w]. If you want to see the words in inverted order (high-
order byte first), press [W]. Press the same key again to return to
the normal byte display.
Version 5.42 (changes since 5.34)
=================================
1. You may delete a subdirectory that is not empty. When you press
[F7], EDDY will tell you if this is the case, and wait for you to
decide whether to proceed. If you do go ahead with the delete, all
files - and all subdirectories below the current one, plus all of
their files - will be deleted when you UPDATE. Read only attributes
on files or subordinate subdirectories will be ignored.
2. The LOOK mode functions are now in a separate program module -
EDDYLOOK.AUX - which is loaded only when required. This results in
three improvements: 1) EDDY can display more files (up to around
400); 2) more memory is available for use with the DOS Gateway; and
3) the initial program load is slightly faster.
3. EDDY can switch freely between SUBST'ed drives and subdirectories
and their un-SUBST'ed, fully expanded path equivalents. See EDDY.DOC,
Section 5.5 for more info on this.
4. [Alt+^F7] flags all files as "ignored". Sounds silly, but see
EDDY.DOC Section 13.1.
5. Customizing by using a previously-customized version of EDDY (item
5, version 5.26, below) is no longer available. The logic needed to
ensure full compatibility between versions is bulkier and more cumber-
some than seems warranted for such an infrequently-used feature.
6. When LOOKing at an entire disk, any sectors which had read errors
when read by DOS are flagged with "???" between the hex and ASCII
portions of the display.
7. When LOOKing at RAM, the display is updated constantly to let you
watch locations that change dynamically (not for CGAs).
Version 5.34 (changes since 5.31)
=================================
1. [S+^F9] is a multi-file "Point-and-shoot" for ALL displayed files,
allowing you to process a list of files with the command(s) of your
choice - e.g., MASM, PRINT, PKARC, WS or ???. See EDDY.DOC Section
15.2.2.
2. Comparing files - [Alt+S+F3] - has been enhanced to tell you where the
differences in files are, including in files of different lengths.
3. A file that has been "ignored" - [Alt+F7] - is "un-ignored" only when
a command affecting that file is performed.
4. When you exit to DOS from EDDY using [F9], the "prompt" string is
changed to include the characters "Exit]" at the end. This is to
remind you that EDDY is still active, and needs eventually to be
EXITed to and terminated. See EDDY.DOC Section 24.3.1 if you don't
like this change.
Version 5.31 (changes since 5.27)
=================================
1. [S+^F3] compares all working directory entries to their correspon-
ding target directory entries. For each entry, the result of the
comparison is displayed, and EDDY pauses until a key is pressed.
2. When the display is in inverted order (e.g., after [Alt+i]), moving
the cursor to the bottom of a subdirectory list via [PgDn] or [^End]
leaves the cursor on the '..' entry, ready for a possible [F3].
3. Option /I is eliminated.
4. Mailing address on final display changed.
Version 5.27 (changes since 5.26)
=================================
1. Copying and moving is now done AFTER all other changes - renaming,
timestamp, attributes - have been made to a file. Previously, copies
and moves were done first.
Version 5.26 (changes since 5.17)
=================================
1. Pressing [Alt+S+F3] compares the contents of the current file to a
file with the same name in the target directory, and reports
whether they are identical or not.
2. EDDY now has a "point-and-shoot" capability. You can define
commands to be executed on specified files, without leaving EDDY, by
creating a file called "EDDY.USE". For example, if EDDY.USE
contains the line:
*.ARC C:\UTIL\PKARC V %1
pressing [S+F9] while the cursor is on a file with a ".ARC"
extension will display the contents of that file.
3. When the cursor is on a ".COM", ".EXE" or ".BAT" file, pressing
[Alt+F9] executes that file, then returns to EDDY.
4. The COPY/MOVE/DELETE Controls default settings are changed to
Y,Y,C,C,N,N.
5. If you are upgrading to a new level of EDDY, and you already have an
old copy customized the way you like it, you may tell EDDY to create
the new version with the same customized configuration as the old.
See EDDY.DOC, Section 24.3.
Version 5.17 (changes since 5.05)
=================================
1. A "FIND and REPLACE" function is now available. It is toggled
ON/OFF by pressing [Alt+r] while the FIND window is displayed. If you
start a search (by pressing [Enter] or [^Enter]) while the "REPLACE"
portion of the window is displayed, REPLACE is activated whenever a
match is found.
2. [End] is used to mark the end of a FIND string, rather than [Up].
3. COPY, MOVE, DELETE and DESTROY can now be done in batch mode.
4. The file attribute heading letters have been changed from "RHSDAN"
to "RHYDAS"; the meaning of "S" is now "Shared" (replacing "N"
for "Network"), and "Y" means "sYstem".
5. The following operations are not allowed on network drives or on
disks larger than 32 MB:
- Any action (LOOK, PATCH, etc.) on the disk as a whole
- Moving directories
- Changing directory timestamps
6. The COPY/MOVE Controls may be used to govern the selection of files
to be deleted, also. This is useful when "cleaning up" a disk with
lots of duplicate files in various directories. You may, for
example, tell EDDY to delete only files that are also in the target,
and which have timestamps older than or the same as that file in the
target. See EDDY.DOC, Sections 10 and 12.2.
The default settings for the Controls are N,Y,C,C,N,N.
7. When LOOKing at a file, [F3] has the same effect as [Esc], thus
saving a finger move between keys. [F4] works similarly for PATCH.
Version 5.05 (changes since 5.01)
=================================
1. You may move subdirectories, including any files and other direc-
tories they may contain (i.e., "prune and graft").
2. You may change the timestamp on directories.
3. In LOOK mode, [Alt+p] prints the file. Printing starts with the
first line of the display, and continues until a key is pressed.
4. In LOOK mode, [e] toggles EGA/VGA monitor between 25 lines per
screen and 43/50 lines.
5. The DOS gateway is now available in LOOK mode, by pressing [F9].
Version 5.01 (changes since 4.16)
=================================
1. You may now LOOK at, FIND strings on, PATCH and COPY data from disks
directly by physical sectors, without regard to file or directory
structure. It's all described in Section 19 of EDDY.DOC. (In
version 5.08 and later, Section 21). Extreme caution advised!
PATCHing for physical disk sectors can also be permanently disabled,
if you want to put EDDY on a machine which potentially-mischievous
people can access.
2. EDDY now does data recovery. Using the above features, you can
easily select data to be copied to a target file. No dangerous
direct patching of directories and FATs required to recover a
deleted file. See Section 20 (in 5.08, 22) for details.
3. A file that is tagged for "Copy" may also be tagged so that the
new copy will be bit-stripped (any high-order bits removed) and/or
have any TAB characters expanded. This is done by pressing [Alt+b]
or [Alt+number], respectively. These commands have the same effect
on the new copy that they would have on the LOOK mode display for
the file.
The file must already be tagged for "Copy" before these commands
will work.
4. Option /D, directory sizing, has been introduced. Normally, the
disk space used to hold subdirectories is not included in EDDY's
display or calculations. If you turn on option /D, all such space
will be accounted for in the display. However, the processing
needed to gather the information is VERY time-consuming, so you may
only wish to use it in cases where the information is really
important.
5. Some users report program "hangs" (or no response at all) when
certain keys or key combinations are used. If this happens to you,
try using option /I when you execute EDDY. Option /I tells EDDY to
use BIOS calls to access the keyboard, rather than the DOS calls
used normally. It also enables cursor size changes, and the pitch
and duration of "beeps" are controlled by EDDY, rather than DOS.
6. The display heading and the update summary display reflect the
actual physical disks involved, even if they are SUBST'ed or ASSIGN'ed.
7. When entering FIND strings, the "don't match" attribute is specified
by pressing [Alt+k] instead of [Alt+m].
8. HELP now offers menu selection of HELP topics. [F1] while in HELP
displays the menu, providing a "HELP-for-HELP" facility.
9. Auto-scroll works only in LOOK mode.
10. The suggested registration fee is increased to $20.00.
Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
