++ 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 section describes functionality changes other than minor bug
fixes. Changes in the current version of EDDY are described first.
Changes to versions prior to 6a 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 7q
==========
1. Fix problem with message displays for "Jump" command in LOOK mode
Version 7p (version 7o skipped)
==========
1. The target directory currently in use (if any) is always shown in
the lower right hand corner of the EDIT mode display. This is
introduced in connection with item #2, below; however, having worked
with it a bit, I don't know why I didn't do this a long time ago!
2. "Target tracking" is provided to assist in synchronizing directories
that have similar subdirectories but different parent directories.
This is explained more fully in EDDY.DOC, Section 5.2.3.
3. If while you are LOOKing at a file, you exit to DOS and modify or
delete that file, EDDY will display a message to that effect.
Version 7n
==========
1. Pressing [^\] from EDIT mode displays a list of valid drives (as
previously). Selecting a drive other than the working directory's
drive changes the working directory to be the DOS default directory
on the selected drive. If the drive you select is the same as the
working directory's drive, the working directory is set to be the
root directory of that drive.
Previously, when you pressed [^\] from EDIT mode, and you were not
using the "tree" method for directory selection, you would be placed
in tree select mode as soon as you pressed a drive letter.
2. [^f] will FIND strings in any file in the directory tree, rather
than just in the working directory. If you press [^f] and there are
subdirectories in the working directory, you'll be asked whether you
wish to search those as well.
3. The SNAPSHOT facility is improved. When you take a snapshot --
[Shift+F5] -- of a directory that has subdirectories, you will be
given the choice to "snap" the entire subtree. If you choose this,
snapshot files will be created in each subdirectory. Then when you
later compare snapshots to current directory contents -- [Shift+F3]
-- you will see exactly where within that entire tree changes have
been made.
4. You can have multiple commands in EDDY.USE for the same files. Best
is to put the command you use most frequently first, followed by
others that you sometimes use. See EDDY.USE for an example of this
with respect to ZIP files. If the command displayed when you first
press [Shift+F9] is not the one you want, press [PgDn] to get the
next one.
5. When you use the keyword search facility in HELP, the lines where
the keywords are will be in reverse video.
Version 7m
==========
1. Now there's assistance to cope with EDDY's mushrooming "feature-
itis": you can find HELP on a subject by doing a keyword search on
EDDY's entire set of HELP screens (over 40), rather than tediously
paging through them. Press [F1] for HELP-in-context, as always, and
then press [F1] again for the HELP topic menu. A new selection
there is "Topic Search by Keyword". Press [Enter], and follow the
directions from there. You may also use [Shift+F1] as a shortcut.
2. When copying portions of a disk image, you may now override the
default filename if you wish.
3. You can select portions of a file, disk or RAM by "marking" them
(press [m] in LOOK mode). Marking causes the selected portion to be
highlighted in the display. You may then copy the marked area to a
file (your choice of name), or copy everything EXCEPT the marked
area. Marking is described in EDDY.DOC, section 8.6.
4. When LOOKing at a disk, pressing [Tab] produces a formatted,
readable display of the disk's boot sector.
5. When LOOKing at a disk, pressing [@] produces a formatted, readable
display of the disk's Master Boot Record, if there is one. When the
boot sector (offset 00000000h) is on screen, pressing [PgUp] has the
same effect as [@].
6. With EDDY's "filter" functions ([Alt+a] or [Alt+q]), directories are
not shown in the resulting display unless they satisfy the filter
criteria. If you use [^a] or [^q] instead, you will be given the
choice of whether to display directories or not.
7. Printing may be directed to a file (your choice of name), by using
[^p] rather than [Alt+p]. If your printer is on a port other than
EDDY's default of LPT1, the default port may be changed.
8. You may create "list files" -- ASCII text files with lists of chosen
filenames -- by pressing [Alt+l]. See Section 1.6 of EDDY.DOC for
info on how to and why you might do this.
Version 7L
==========
1. When a file is tagged for "Copy" or "Move", and there is no file of
the same name already in the target directory, a "Copy+" or "Move+"
will appear.
2. When LOOKing at a directory entry on disk, the display produced by
pressing [Alt+d] is changed so that the attributes are shown in the
same order as their corresponding bits in the attribute byte.
Version 7k
==========
This is primarily a maintenance release, addressing these problems:
7k - When marking and copying sectors on disks having a cluster size
equal to the sector size (i.e., many floppies), the SECTORS.{x}
file created was always empty.
7j - With disks having a number of clusters larger than 32,767, use of
option /D sometimes produced invalid directory sizes (too large).
7j - With these disks, operations on the directory tree (Copy, Move,
Delete) sometimes hung the system.
7h - Paths and filenames containing the "invisible" character 0FFh were
not displayed properly, and hung the system if used with the tree
selection feature for working/target directory changing.
These problems are now fixed.
Some minor enhancements:
1. When you press [Shift+F9] to execute a command from EDDY.USE on the
current file, AND the current file matches EDDY.USE only on an entry
in EDDY.USE starting with "*.*", AND the current file is executable
(.BAT, .COM or .EXE), the command from EDDY.USE will not be used.
Instead, EDDY will offer to execute the current file, just as though
you had pressed [Alt+F9] originally.
2. When doing a FIND, [/] works identically to [f].
3. When doing a directory MOVE (not using the "fast move" method), EDDY
copies the tree to the target, then deletes the tree from the
working directory. As an additional safety measure, you are asked
whether you want this final deletion to proceed. If not, the result
is as though you had done a COPY rather than a MOVE.
Version 7g
==========
1. You can record the contents of a directory (a "snapshot") by
pressing [Shift+F5] on either the top ("DIR of...") line or the "."
line of the display. This creates a file -- SNAPSHOT{.} -- which
EDDY may later use (if you press [Shift+F3] on one of those same
lines) to compare with the current directory, and tell you of any
changes which have occurred since the snapshot was taken.
2. In LOOKing at text files, line numbers up to 999,999 are displayed;
before, the displayed line number "wrapped" at 65,535.
Version 7f
==========
The main reason for this version is to correct some problems that have
crept in, appearing only to users of XT-class systems. My own XT went
south a few months ago, and I have failed to test new releases on that
platform. However, a good proportion of my user base is using XTs, and
their complaints are coming in!
Anyway... I've found another XT, and I'll test all future releases on
it. I think the platform-related bugs are all fixed -- the worst was a
"red-button" hang on some machines as soon as the initial display came
up. There was also a lot of unnecessary re-displaying that made EDDY
virtually unusable for anyone using a slower screen, such as a CGA.
Other changes:
1. [Alt+0] thru [Alt+8] previously tagged a file for COPY with TAB
removal; now only [Alt+0] is used for this, and EDDY will ask you to
provide the desired TAB interval separately.
Version 7e
==========
1. Data error ("bad spot") recovery is improved: When copying or
moving files that have read errors, you may choose to skip the bad
data, copy it as is, or replace the bad data with "#"s (or other
character, if you customize EDDY).
2. Some of the files have been renamed, so that they once again all
begin with "EDDY", and so won't overwrite files from other packages
when you copy them (except for FILE_ID.DIZ - no choice on that).
Version 7d
==========
1. Registration info is available by pressing [Alt+z].
2. You can copy and move directories, with all their files and sub-
directories, from any disk to any other disk.
3. The COPY/MOVE/DELETE Controls are now called "Synchronization
Controls". Their function remains the same, but the description of
their use (in EDDY.DOC) has been expanded and (hopefully) clarified.
4. If you rename a file, even before you update to make the new name
permanent, the new name will be used in any comparisons made (e.g.,
[Shift+F3], [Alt+Shift+F3]). Thus you may type the new name over
the old to do comparisons between files and directory entries which
have different names, and then UNDO the rename if you don't really
want to make the change. The new name will also be used for
comparing timestamps for copy and move operations, according to the
settings of the Synchronization Controls.
5. Disk image copying has been changed. The name of the file in which
a full disk image will be stored is now "DRIVE.{C}" (if you're
copying from drive C:). If you mark and then copy selected portions
of a disk, the data will be written to a file named "SECTORS.{C}".
You may copy all or part of the disk's system area -- boot sector,
FAT, root directory -- without copying the entire disk.
6. EDDY no longer restricts you from patching sectors on a compressed
disk (Stacker, et al). After a warning, you may proceed if you
really want to.
7. Volume labelling capabilities are expanded. A label may contain
ANYTHING you want -- even "\", ":", etc. It may even be set to all
spaces if you wish. Labels may also be deleted.
8. When using the default point-n-shoot command -- [Shift+F8] or
[Shift+^F8] -- you may choose whether to pause after the command is
executed or not, and whether the command should execute only on
files with the same extension as the current file or on any file.
9. The Synchronization Control setting of "C" is now used in batch mode
as well as interactively. See EDDY.DOC, Section 24.3 for more info.
10. Some users have complained that their mice move erratically,
especially when using the menus. Although unable to reproduce this
problem, I have changed EDDY to reduce the horizontal mouse
sensitivity by half when working with menus. I hope this helps.
Version 7c
==========
1. Now you can register your copy of EDDY by credit card! Please see
details in EDDY.DOC, Section 27.2.
2. Directory sorting can 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, 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 tagged "Copy image", rather than
"Copy(!)" as previously). Thus, [^m], previously used as the "Mark
all" command, is no longer used. If you press it by mistake, it
acts just like [Alt+m]: "Jump to first mark".
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
==========
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 20 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 26.3.4 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 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 shown 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
==========
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 moving into the modern world. There
is now support for mice (Microsoft-compatible variety, since that's
all I've got to test with). Details 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
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 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 combined, along with the new MENU
functions and UPDATE processing, into the single EDDY.AUX file.
EDDY.HST, EDDY.WHY and EDDY.REG are called EDDY_HST.DOC,
EDDY_WHY.DOC and EDDY_REG.DOC, respectively.
