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 4.15 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 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> om 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 SUBSTed or ASSIGNed,

    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.


    Version 4.16 (changes since 4.15)
    =================================

    1.  When option /F is ON (file renaming enabled), a "." appears between
        the filename and extension fields in the display.  If it is ON for
        only the current file (i.e., you pressed <Ins>), then only that
        file's display has the ".".

    2.  If you rename EDDY.COM, and use the new name to execute EDDY, (and
        you are using DOS 3.0 or later), the initial HELP screen will always
        be suppressed.

    3.  You may include default attribute filters when customizing.  This
        could be used, for example, to suppress display of hidden files
        unless you explicitly ask for them.

    4.  If you turn on option /K, then the key you use to respond to the
        "Press a key..." message will be used as a command if it is one of
        the valid command keys.

    5.  If you made an error in the target directory specification on the
        command line, earlier versions of EDDY terminated with an error
        message.  Now, the working directory is displayed normally, and a
        new target is requested, just as though you had pressed <Alt-t>.
