     Changes in Version 7.11
     -----------------------
     Ý   I decided I wasn't happy with the way that an empty Selector was
         not being pushed through your cursor via a Mover when you pushed
         a Slider out of the way so that Mover could now move.  In other
         words, this is what happened before:
                         _
                 -   |   -  <
                     o

        The westbound Mover ("<") can't move as it's being held in place
        by the north-south Slider ("|").  Before, if you ("o") pushed that
        Slider out of the way, this would result:

                     |   _
                 -   o   -  <

        Now, this results:

                    |
                    _  
                -   o  <
                    -

       The open faced Selector is pushed into you.  This change is more
       logical and I should have thought of this years ago.  Fortunately,
       it only affects the solution of but one room out of all 120.
       (Puzzle # 30, "But Ma...")



     Changes in Version 7.07
     -----------------------
     Ý   Very minor change.  If a player loaded a cursor-image file, and
         then exited the program, the configuration file was, of course,
         saving this file and automatically loading it next time the
         program was run.  So far so good.  However, if for some reason
         this file was missing or had been deleted, the program was
         reporting this with a polite error message, stating that it could
         not find the file and then did not load.  Now, in such a
         scenario, the program will first attempt to load the default
         cursr-01.dat image file.  Only then, if it doesn't find THIS
         file, will the program report an error and then not load.



     Changes in Version 7.06
     -----------------------
     Ý   My brother and his son, after all this time, found a tiny glitch.
         If a ZAPPER, the type that zaps you north, was placed on the top
         row, attempting to zap through it (which should do nothing)
         inadvertently zapped you out of the room.  This is now fixed.



     Changes in Version 7.05
     -----------------------
     Ý   The time stamp for all of the files associated with the program
         will now be the same as the version number.



     Changes in Version 7.04
     -----------------------
     Ý   Changed all references of "Ed's" shortest solution to simply
         the shortest "known" solution. 



     Changes in Version 7.03
     -----------------------
     Ý   Reduced the amount of conventional memory needed to run the
         program down to 390 Kb (385 for the deluxe version) from 405 Kb.



     Changes in Version 7.02
     -----------------------
     Ý   Added the "no-auto" command-line switch which disables the
         "auto repeat" feature in regards to the cursor movement.  (Many
         people with cerebral palsy and similar conditions will "freeze"
         on a key after pressing it.)  Thanks to Michael Donn of LakeBay,
         Washington for this suggestion.

     Ý   Added some additional user comments in the final screens of the
         non-deluxe version.
        
         

     Changes in Version 7.00
     -----------------------
     Ý   The naming convention for the room volumes has been changed.  The
         room volumes are now known as V-XXX-NN.DAT, where XXX indicates
         the initials of the author and NN indicates the volume number.

     Ý   The deluxe version now defaults to opening the v-edc-02.dat      
         room-volume file if no configuration file is present.

     Ý   The documentation files for both CA-Cyber and the CA-Edit program
         (the editor) have been given a TXT rather than a DOC extension.

     Ý   Fixed a minor glitch involving the Take Back feature after one
         recalled a room position that had been saved.

     Ý   Fixed a very minor glitch involving the help menu in the
         documentation file.

     Ý   While in the demo mode, the cursor no longer "backs up" one move 
         after exiting the room.



     Changes in Version 6.95
     -----------------------
     Ý   Fixed a minor glitch involving the east-west selectors.

     Ý   The room was not being set back properly if one executed the
         "take back" feature immediately after viewing a previous
         solved solution.  Now fixed.  Thanks to Michael Donn of Lakebay,
         Washington for discovering this.

     Ý   The deluxe version now defaults to opening the 001 room volume
         data file, if no configuration file is present.

     Ý   The CA-EDIT program, when it first runs, creates a "vol-new.dat"
         file.  You can now load this file with the ALT-V shortcut key
         simply by hitting your "n" key after executing ALT-V.

     Ý   The program will no longer abort if the last room-volume data
         file that you were playing is not found in the current directory.
         If this data file is not found, it will now try to load the
         default 002 data file.  Only if this 002 data file is not found,
         will the program abort with an appropriate error message.



     Changes in Version 6.81
     -----------------------
     Ý   One user reported problems while inside both the Jump and the
         Option Screen.  I happen to be using CALL INTERRUPT logic while
         inside these screens which displays certain text characters in a
         slightly smaller font.  I've added a new command-line switch
         (no-interrupt) to turn this logic OFF in case others have the
         same problem.



     Changes in Version 6.73
     -----------------------
     Ý   The format of the room-volume data files has been changed.  Now,
         the number of moves that it takes me to exit each room is also
         hard-coded here, in addition to existing in each solution file.
         This way if the player wishes to NOT keep the solution files in
         the same directory as the program, they will still be able to
         glance at the number of moves that it takes me to exit each room.

     Ý   Made another minor change in the 'special treat' logic.

     Ý   The program now loads the vol-002.dat file by default.



     Changes in Version 6.61
     -----------------------
     Ý   I wanted the player to experience a 'special treat' if they
         could solve all 15 rooms during the same session.  However, I was
         keeping track of the number of times ANY room was solved and was
         simply executing my 'special treat' logic when this counter
         reached 15.  That means that a player could have solved, say,
         Room 001 over and over again (15 times) for the treat.  This is
         now fixed so that ALL 15 rooms need to be solved.  Thanks to
         Martin Kirlow of Yorkshire, England for informing me of this.



     Changes in Version 6.51
     -----------------------
     Ý   Changed a minor glitch in the Jump Screen in the Deluxe Version.
         If a player solved a few of the rooms in one volume and then
         loaded another volume, the Jump Screen was still highlighting the
         room numbers (indicating that they had been solved) from the
         first volume.



     Changes in Version 6.41
     -----------------------
     Ý   Changed the MOVER logic BACK to the way that it was in version
         6.16.



     Changes in Version 6.31
     -----------------------
     Ý   It turns out that the MOVER logic that was changed in the 6.16
         update was still not 100% identical with Petr Simon's CyberBox
         Forever program.  This is now fixed.



     Changes in Version 6.25
     -----------------------
     Ý   Corrected a very minor glitch in the logic which displays the
         documentation file.

     Ý   Jazzed up the documentation file ever further.

     Ý   The program was adding an extra UP keystroke tacked on to the
         end of the each solution of each solved room.  The result was
         that while later VIEWING this solution, the program was reporting
         that it took you an extra move to get out than what it really
         did.  This is now fixed.

     Ý   Removed the REVISIONS section from the documentation file.  This
         section is now being kept in its own revision.txt file.  This
         frees up more conventional memory for the program.

     Ý   The color choices that the player selects for the both the
         menu foreground color and menu background, while viewing
         the documentation file, are now being saved in the configuration
         file.  (They weren't before and probably always should have
         been.  I'm saving all the OTHER player preferences.  Why not
         these as well!)



     Changes in Version 6.16
     -----------------------
     Ý   Added the new "north-south" and "east-west" SELECTORS.

     Ý   Re-coded the logic in regards to how the MOVERS operate in
         relationship to each other.  The logic is now consistent with
         Petr Simon's CYBERBOX FOREVER game and we both feel it looks much
         more professional.  (Different MOVERS now move simultaneously!)

     Ý   Renamed the cursor-image data files to "cursr-xx.dat."  The
         previous naming convention ("images-xx.dat") might be mistaken
         for the new box-image data files.

     Ý   Jazzed up the way I display my headers in the documentation
         file while viewing the above mentioned file from within this
         program.

     Ý   While returning to a room from the Jump Screen or Options Screen
         etc., the entire room arrangement is displayed all at once.

     Ý   Corrected a minor bug in the Options Screen.  Thanks, Petr.



     Changes in Version 6.01
     -----------------------
     Ý   Added the "no-doc" command-line switch, which forces the program
         to NOT load the documentation file.  This allows the program to
         run in almost 75K less of conventional memory.



     Changes in Version 6.00
     -----------------------
     Ý   Changed the format of the cursor-image data files.  The current
         format takes up less hard disk space, loads slightly faster and
         is easier to modify.

     Ý   Completely changed the format of the solution files.  Each
         solution file is now approximately 1,300 bytes in size, (when all
         15 rooms have been solved) compared to 75,030 before!

     Ý   Reduced the number of valid keystrokes allowed from 5000 to
         3000.  This reduction allows the program to run in less
         conventional memory than before.  (I can't see a room EVER
         requiring anywhere NEAR 3000 moves to exit, much less 5000.)

     Ý   Eliminated the hard-coding of the boxes.  Instead, this
         information is being read in from the new box-image data files.
         (This further reduces the amount of conventional memory required
         by the program as well as allowing the player to change the way
         any of the boxes look to suit them if they so desire!) 

     Ý   Since I've introduced a new box (the PULLERS) since Doug's
         original game, and since the opposite of "pull" is "push", I
         decided to rename the SLIDERS to PUSHERS and the PUSHERS to
         MOVERS throughout both the program and documentation.  (Sorry,
         Doug.)

     Ý   I'm no longer writing the configuration file and solution files
         with the hidden attribute byte.

     Ý   I'm now including a solution file with the non-deluxe package
         which includes the solution to the first three rooms. 

     Ý   The entire high-score logic has been eliminated.  Your
         "high-score" is simply your "best solution" which is now saved in
         the solution file SEPARATELY from mine.

     Ý   The player can now immediately jump to a room that they've just
         completed if they wish to immediately attempt to better their
         solution.

     Ý   Re-wrote the code that I use to display my documentation file.
         The screen writes are slightly smoother now (not that it was bad
         before).  Also, I added a 'bookmark' feature which allows the
         user to place a bookmark in a page and then return to that page
         at any time with just a keystroke.

     Ý   Added the SAVE feature (ALT-S) which allows the player to SAVE
         a position in memory which they can then recall (ALT-R) at any
         time before leaving the room.

     Ý   If the name of the author of the room being loaded is different
         than the previous author's name, this new name will now blink a
         few times, to help call attention to the fact.

     Ý   Added the new MOVER animation code.

     Ý   The opening and title screens both now appear slightly faster.

     Ý   Upon returning to a room, the player's cursor now blinks for a
         slightly shorter period of time.

     Ý   Added the code to immediately jump to the next room (ALT-N) or 
         the previous room (ALT-P).

     Ý   Added the Summary of Available Keys screen.
     
     Ý   Changed the way that the closing screens look in both the Deluxe
         and Non-deluxe versions.

     Ý   Improved the format of the Jump Screen.  Now, the lowest solution
         to all 15 rooms can be seen at a glance.

     Ý   The screen-writes to both the Jump Screen and the Options Screen
         are noticeably faster.

     Ý   Eliminated the checkdigit figure from the room-volume data files.
         The program now keeps the checkdigit figure in the solution file
         and if the room has been changed in any way, the program simply
         deletes the current solution.

     Ý   Changed the length of the room number from four digits to three.



     Changes in Version 5.00
     -----------------------
     Ý   No such version.  I made so many changes after 4.61 that I felt
         a another full digit increase in the version number was
         warranted.



     Changes in Version 4.61
     -----------------------
     Ý   Corrected a bug indirectly caused by the bug fix in the last
         update.



     Changes in Version 4.60
     -----------------------
     Ý   Corrected a bug.  The program, under certain conditions, was
         not saving the high-score file correctly.  I can't believe
         this wasn't noticed by someone earlier.  Many thanks to Petr
         Simon of the Czech Republic for informing me of this.



     Changes in Version 4.54
     -----------------------
     Ý   Added the TAKE BACK feature.

     Ý   Corrected another minor programming bug in the Deluxe version.
         If a player attempted to load a non-existent cursor-image file
         via the ALT-I key combination and then exited the program, the
         same problem that I mentioned in the 4.43 update occurred; the
         program was saving that invalid filename in the configuration
         file before checking to see if it was valid.  The program would
         then not load properly the next time it was started.  Now fixed.

     Ý   Changed the program logic for paging up and down in the
         documentation file.  The program will now display a entirely
         new set of 23 lines of text per screen rather than 22.

     Ý   Changed the requirements in one of the "annoying delay screens"
         seen at the end of the non-deluxe version.  I now recommend that
         SIX files, rather than four, be included when distributing the
         non-deluxe version.  The new additions are the icon file
         (ca-cyber.icn) and the file description file (file_id.diz).



     Changes in Version 4.43
     -----------------------
     Ý   Corrected a minor programming bug in the Deluxe version.
         If a player attempted to load a non-existent room-volume via the
         ALT-R key combination and then exited the program, the
         programming logic would update the configuration file with this
         invalid room-volume name.  The next time that the program was
         loaded, an error message would appear stating that it was
         attempting to load this file and could not find it.  (The
         configuration file saves the last room-volume that has been
         played.  It was saving a filename BEFORE checking to make sure
         that it was valid.)  This bug has now been fixed.  Thanks to Lyle
         Engle of Mesa, Arizona for discovering this.

     Ý   After exiting the program and returning to DOS, the screen is
         restored to the way it looked before the program was executed.

     Ý   Added some undocumented features for my own benefit.



     Changes in Version 4.35
     -----------------------
     Ý   Corrected a minor flaw in the way that I was drawing a few of my
         letters for one of my fonts.

     Ý   Added program logic to verify that the rooms in the vol-xxx.dat
         data files are in the correct order.  (Previously, one could go
         in and edit these data files and, for example, swap rooms 1 and
         2.)  I didn't have a problem with anyone doing this (although I'm
         not sure why anyone would ever WANT to) but the vol-xxx.sol files
         contain the SOLUTION to these rooms and if one swapped any of
         the rooms in the data files then one would HAVE to swap these two
         solutions in the solution file as well (to keep the program from
         doing strange things).  And my solution files, being non-text
         files, would be extremely difficult (if not impossible) for the
         average player to manipulate anyway.

     Ý   Since the documentation file is now REQUIRED to run the program,
         I added a "read-only" attribute byte on this documentation file,
         to lessen the chance that it will be deleted accidentally.

     Ý   Allowed the player to select any of the menu key options via the
         TAB and/or the CTRL-arrow keys.

     Ý   Made a minor change to the program logic when the cursor exits a
         room and actually enters the hallway.  (If the cursor-movement
         sound was active for any pitch, a slight pause occurred before
         the sound was heard.)



     Changes in Version 4.23
     -----------------------
     Ý   Changed the order of the options of the <M>enu Toggle so that the
         ALT-key options appears second rather than third.

     Ý   Changed the logic so that if the player is reading the
         documentation file and then returns to the game, the same page
         that the player was reading is automatically brought up again if
         and when the player decides to read the doc file a second time.

     Ý   Allowed the player to change the foreground and background colors
         while reading my documentation file.



     Changes in Version 4.15
     -----------------------
     Ý   Deluxe version - changed the configuration file so that it would
         save the last cursor-image data file that you were using as well
         as the last room-volume data file that you were working on.

     Ý   Changed the program logic so that this configuration file is now
         read first.  The program will now no longer default to loading
         the vol-001.dat file and cursr-01.dat file.  The default now
         becomes whatever files you previously had loaded.

     Ý   Deluxe version - added code so that the player can load
         additional room-volumes and cursor-image files from right inside
         the program.

     Ý   If the player's efforts are good enough for the CyberBox Hall
         of Fame, for convenience, the program will now automatically
         display the last name that was previously entered in this screen.
         If the player wishes to use this same name, now all he or she has
         to do is hit ENTER.

     Ý   Allowed the player to read my documentation file from right
         inside the program.



     Changes in Version 4.0
     ----------------------
     Ý   Added the DOS shell.

     Ý   Added the entire solution-file logic.  The program now saves your
         shortest solution to disk.

     Ý   Swapped a couple of rooms in the vol-001.dat file that were a
         little too difficult to solve for first-time players, with some
         rooms in my vol-002.dat file.

     Ý   Added logic so that the player can break out of the 'special
         treat' logic if so desired, by hitting the ESCAPE key.

     Ý   Increased the number of <I>nstant Replay keystrokes saved in
         memory from 2000 to 5000.



     Changes in Version 3.0
     ----------------------
     Ý   Renamed my cursor-image data files to IMAGESxx.DAT (where "x"
         indicates the file number) instead of CACYBERx.IMG

     Ý   Added the entire <I>nstant Replay logic.

     Ý   Added the "About CyberBox" screen.

     Ý   The program now puts a read-only attribute byte on both the
         room-volume and cursor-image files.

     Ý   Changed the appearance of one of the BLOCKER options from a
         sorry looking solid-red block to a neat little criss-cross type
         pattern.

     Ý   When entering a room for the first time, the NAME of each room is
         animated from right to left until it is centered in the right
         hand portion of the screen.

     Ý   Removed my LINE INPUT statement for accepting the player's name
         in my Hall of Fame screen and replaced it with my own editor.
         (Which allows for the player to utilize the HOME key, the END
         key, etc.)



     Changes in Version 2.0
     ----------------------
     Ý   The program now puts a hidden attribute byte on the high-score
         and configuration files.

     Ý   Re-wrote the logic for drawing all boxes.  (The screen-writes on
         slower PC's was a little too slow for my taste.  It is now
         noticeably faster only at the cost of the program now requiring
         slightly more RAM to load and run.)

     Ý   The ESCAPE key will now bring up the "Do you really want to
         quit?" message, in addition to the "X" (e<x>it program) key.

     Ý   If the replay animation speed is set on "very fast," the program
         will now replay the solution WITHOUT the "cursor sound."
         (Assuming the cursor movement sound was active for any pitch in
         the first place.)  The sound could not keep up with the cursor
         movement and the result was the cursor running around with one
         big beeeeeeeeeeeeeeep.)

     Ý   Changed all references of "non-registered game" to "non-deluxe
         game."

     Ý   When entering a room for the first time, your cursor now blinks
         a few times to make it easier to find.

     Ý   Added the <B>ox Review screen to help out first-time players.



     Changes in Version 1.14
     -----------------------
     Ý   Changed the default text color from white to brown and the
         default highlight color from bright white to yellow.

     Ý   The program will now re-write the configuration file only if
         anything has changed since initially loading it.

     Ý   Changed the opening screen to display the message "Hit any key to
         continue..." at the bottom.

     Ý   Slightly altered the way that the PULLERS are represented.
