                     DoubleTake Professional
                      by John L. Dove III
                        Version History

2.5  5/31/93    First major update.
     New Features:

       Added a Full Zoom mode which eliminates the two bottom lines
         and all borders for extra room in the viewing area.
         Now 25-line gives 12 lines per file.  EGA 43 line mode
         gives 21 lines and VGA 50 gives 24 per file.
         This also eliminates any distration the bottom lines may
         have caused.

       Added the Invoke Editor command.  Pressing [Alt-E] runs
         DublTkEd.bat with both filenames (if two are selected). If
         only one file is to be edited, Zoom that window and
         press Alt-E. DublTkEd.bat (provided) contains the command
         for your editor (such as DOS Edit.exe).
         DoubleTake passes the two file names and the line number
         for each file sent so you can use an editor which places
         the file at the current line when the editor starts.

         There are sample BAT files:  For editors which can handle
         starting lines on the command line, one for editors which
         can handle multiple filenames on the command line and one
         for editors which can only take one name at a time.  You must
         copy your choice to the appropriate filenames so the correct
         editor is called when you press [Alt-E].

         The edited file is reloaded, so you will see all the changes
         made.  It is also reloaded back to the approximate spot where
         you were viewing when you invoked the editor.

       The Border Color can now be set independently.

       DT now checks for the number of drives and shows only those
         when the Directory Picker is called.  Now will recognize
         Network drives for use on a LAN and RAM drives.

       In Hex mode, now both byte number and byte value show in
         either Hex or Decimal.  The normal decimal Byte number
         value is simply the numbers; the hex Byte number has a
         $ (dollar sign) preceding the number.

     Fixes:
       Find Next Mismatch was not ignoring case as set in defaults.
       Fixed the Directory Picker.  When you entered an erroneous file
         on the command line, DT would shift to one-file mode, not
         allowing you to enter two files.
       When [Alt-F] is pressed followed by [Esc], the windows were
         cleared.  Fixed so that the files are re-displayed.
       The Pick List was not handling empty (0 length) files correctly.
       DoubleTake was erroneously reporting not enough memory in certain
            situations.

2.1 to 2.4 (intermim versions, not released to public)

2.0  7/15/91      Released as DoubleTake Professional
     New Features:
       See file What's New for new features added.

     Fixes:
       Fixed: DoubleTake did not handle DT *.pas correctly (now correctly
         says file not found)
       Fixed ASCII Find next Mismatch/Find String search across lines --
         all "IGNORE" characters are truly ignored.
       Fixed Shell to DOS to caution "Don't load Memory Resident" while
         in Shell  5/25
       Fixed Shell to DOS to return to screen mode when DT was called and
         to return to the chosen mode when returning to DT.
       Fixed Shell to DOS to return to proper disk when exiting, even
         if user has changed the logged drive.
       Changed the scroll routine to use System scrolling so that there
         is less snow in [S]low video mode.

1.7,1.8,1.9  (interim versions, not released)

1.6  5/15/91
     New Features:
       Added an EGA/VGA 43/50/25 configuration option in Config Mode
         and configuration (CNF) file.
       Added the owner's name to the ending screen.
       Changed the Commercial for Reg users.  Must PRESS F1 to get
         commercial - defaults to skip commercial.
       Added an Install routine for Registered users.

     Fixes:
       Fixed abnormal exit with unclear messages when too little memory.
       Fixed Ignore feature to ignore IGNORE CHARS in ASCII
       Enhanced and Fixed the FilePicker routine.
       Fixed a problem with the Parallel Scrolling Mode (was losing a
      line in File 1).  Thanks to Robert L. Maher of Alexandria, VA
      for his comments/suggestions.
       Fixed the Hex Byte counter for end of file errors when moving from
      the next to last line to the last.  It was showing greater than
      last byte.
       Partially restored the Slow video write mode choice.  It is REALLY
      SLOW, however.  It may be worth the snow for the faster screens.
      Will completely include NOSNOW option in future version.  Does
      anyone really use the SLOW (NOSNOW) mode?

1.5  1/2/91
     New Features:
       Now Hex mode is fully scrollable in BOTH directions!  (ASCII is
       coming, but not there yet.)
       Added a confirm (Y/n) for the Left/Right Arrows in ASCII mode.
     Pressing < or > pulls one or the other of the files up to
     the same line number as the other file.  Sometimes annoying if
     you've spent a long time matching files by hand!
     Began releasing DT.EXE compressed with LZEXE.  Now takes less than
       50K.

     Fixes:
       Fixed the Find function in Hex so that it prints the correct
     find string while finding.  It now correctly finds any char
     even if it's an ignore char, but only if BlankIgnore is off
       Fixed the routine which gets a filename at the beginning.
     If you pressed return alone, the entry line would be weird.
       Fixed the Pop-up Display ASCII align functions (they were backwards).
       Fixed a bug in the scroll routines.


1.4    12/20/90
      New features:
    Added a pop-up window when / is pressed.
    Added a commercial when DoubleTake starts and ends
      (and every time Help ([F1] or [?] is pressed) for
      unregistered copies.  Registered copies removes the
      commercial and includes the user's name and serial
      number in the [now optional] commercial screen.

1.3     7/1/90
      New features:
    Added ability to load a new file 1 or 2 (or both) on the fly
       without having to re-start DoubleTake.
    Changed the command line arguments algorithm so that if only
       one file is on the command line, it assumes OneFile mode (use
       previous fix to add second file if this is in error).
    Added routines to ensure that the colors and video mode are
       restored when exiting.
    Changed the Help and ASCII Chart procedures to load the entire
       file with Help (or the ASCII Chart) is first called, rather
       than reloading the file every time it's called.  (If you
       call Help (Help is loaded), then ASCII Chart (ASCII Chart is
       loaded) then Help (Help is loaded again), since the same buffer
       is used for both.  This should rarely occur and it saves having
       a double size buffer.
    Added a page of help for the Add/Delete/Edit Ignore chars routine.
      Fixes:
    FINALLY fixed so that DoubleTake will load and read READ-ONLY
       files.
    Fixed some cases of errors when trying to load *.ext as file 2.
    Fixed so that if you run Configuration from startup, it calls
       the correct help slide.
    Fixed some overspray on my direct video writes.
    Fixed problem with file picker when changing to a drive with
       no files.
    Corrected a miss-spelled word (chara[c]ters) in the Configuration
       Help screen.
    Fixed so that all filenames are converted to Uppercase letters.
        Fixed Find so that it ignores BlankIgnore characters when finding
           a string.
    Moved Find boxes to the bottom so that you can see the screen as
       you are entering the string to find.
        Fixed the command line parser so that it responds correctly to
           DT FILENAME.TYP /X.  (Was treating /X as filename).
        Fixed minor annoyances/problems.

1.2     6/1/90

      New features:
    Added more definitive messages for the results of FindNextMismatches
      and Find Strings (will announce if files are identical).
    Added the ability for DoubleTake to find its Config and Help files:
      - at the spot from which DoubleTake was run or
      - at the spot provided by a SET DT environmental variable (i.e.,
          use SET DT=Path to specify where DoubleTake files are.
    Added the ability to Add/Delete or change the characters that
      DoubleTake ignores when BlankIgnore is ON.
    Added an ASCII chart when editing BlankIgnore characters for
      easy lookup of values to ignore.
    Changed the colors of the Line Numbers to the same as the
      Help Screen.
    Enhanced Hex Mode Cursor left/right move keys so that they scroll
      down a line when right is pushed while on the rightmost character
      and it scrolls up a line when left is pushed on the first char.
      In effect, left/right moves continuously back/forward in a file.
    Added [Shift-Ctrl-Left] and [Shift-Ctrl-Right] to scroll both Hex
      files Left or Right respectively.  ([Shift-Ctrl-F9] and
      [Shift-Ctrl-F10] are equivalents.)
    Added a configure option callable when you start DoubleTake with
      no filenames.
    Changed EGA/VGA toggle to directly toggle to opposite mode
      when [E] pressed (rather than having to choose 25 or 43/50)

      Fixes:
    Fixed ASCII Find String function.
    Fixed the Blinking Cursor so that it stays on the F1-Help prompt
      at the bottom of the screen.
    Fixed the Hilight routine to show blink characters which are
      normally blanks.
    Fixed Hex display to respond correctly to WordStar Mode.
    Fixed Find Next MisMatch to ignore ALL Blanks in ASCII Mode (not
      just those blanks/tabs in the indent)
    Fixed the Hex Find Next Mismatch function to move to next byte
      when it found a previous Mismatch.  If the first byte was
      mismatched, DoubleTake would not move from the first byte.
    Fixed Directory Picker so that if now loads more filenames,
      and indicates "and more" if there's no more memory for files.
      (greater than approximately 380 files)


1.1     5/15/90
    Fixed the ASCII mode to display all characters to screen, even
      for a binary file.
    Added a wide binary Hex mode which shows whole file, 80 chars at
      a time, with the value at the cursor shown at corner of window.
      AltX toggles between Debug-like display and 80 char display
      Also added as a configurable option.
    Simplified/clarified Context Help file DUBLTAKE.HLP.
    Added two Tutorial files to demonstate DoubleTake's features.
    Added a DT-Read.Me file as an introduction.
    Added three batch files to:
       Read DUBLTAKE.DOC using DoubleTake,
       Read DT-Read.Me using DoubleTake, and
       Compare the two Tutorial Files in DoubleTake.

1.0     5/1/90
    DoubleTake Version 1.0 released, formerly GoodLook.

    Version 1.0 has all the previous functionality of
        Version 4.3 of GoodLook (which was never released)
    Also Added:

    Find feature to search either/both files for a string or hex codes
    Cleaner Documentation (with table of contents)
    Fixed Zoom modes so that any scroll key works with the file
       (e.g., Home, UpArrow, & PgUp all scroll the Zoomed file now)

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

4.3     4/15/90  Interim version, not released (Last to bear name GoodLook)
    Added an ignore leading blanks function to compare 2 files with
      different indents
    Added much more functionality to the Hex Mode.
    Added ability (in Hex mode) to toggle between showing chars 0..31,
         128-255 or showing as [.]
    Added an "Ignore leading blanks" function to compare files with
         differing indents.  Shows first difference in rev video.

4.2     July 7, 1989 -Interim Version
    Fixed the problem of not finding ReadOnly Files!
    Recompiled in Turbo 5.5;
    Added Hex Mode (but only works on first 24 characters of each line)
      This Hex Mode is NOT finished.
    Changed address to current Box Office address
    Added a highlight to the first char which is different on compared
       lines.
    Broke out this file separately from the DOC file and inverted the
       order to make it easier to use the ARC Door facilities on most
       BBS's to see what the latest change entails.
    Added option to enter /1 as the second filename to enter the Single-
       File Mode.  This is useful if you forgot to enter /1 on the
       command line.  (The other options can be toggled once inside
       GoodLook.)
    Added the ability to go to DOS temporarily and then return to
       the exact same place as before (Execute a DOS Shell).
    Deleted the main help screens from inside the program and put
       them in a GoodLook.hlp file.  This means less to load on
       startup and they only get loaded if Help is needed.  (I
       read the file directly to Memory so there may be some snow
       on some ancient IBM CGA cards.)

4.1    Fixed the Cursor problem upon exit from EGA 43 line mode.  If you
       ran another program (such as PC-Write) after GoodLook the
       cursor would be in the middle of the line all the time you
       would be in PC-Write and after exit.
       Removed the Drive Test for C: and D: at the startup of GoodLook.
       Thanks for the tip from Ted Decastro.
       Fixed minor problems with the Directory routines at startup. (Now
       when you change drives, you will change to the logged directory
       of the destination drive, vice the root directory.)
       Eliminated keystrokes which should have been disabled when a file is
       Zoomed.

4.0  16 February 1987-Major revision incl/EGA support.
       Added routines to find switches even if they are right next to
       filenames (i.e., File.typ/w, etc.)
       Added routine in Directory-Get routines which will take the first
       character typed and use it as the first in the typed in filename
       Fixed Directory routine to use the correct path when using the
       change drive/directory procedure.
       In Zoom, the proper key definitions now show on the next to last line,
       referring to keys used to move around in File 1, File 2 or both.
       Changed the Beep from ^G to a short Bell routine using the Sound
       procedure to keep the program from getting hung up on the PC's
       beep.
       Fixed the "search for next" algorithm to go to the last line instead
       of stopping on the last page.
       Fixed the "search for next" algorithm to correctly show whether the
       files were the same from the start of compare.
       Changed the Exit to DOS command from ESC to Q to prevent accidentally
       exiting to DOS by pressing ESC twice when leaving Configure.
       Added the [RShift] key as a synonym for the [Ctl] key to alloy one-
       handed movement using [RShift] plus [Home], [End], [PgUp], [PgDn].
       Disabled PrtSc key to avoid inadvertent print screen call.  Added the
       [Alt][P] function to re-enable it if desired to Print the screen.
       Para symbol added to next to last line to show status of PrtSc.
       Added full EGA support;
       Uses the default number of lines in effect when GoodLook is
          invoked, or
       Use the /4 switch on the command line to force the EGA into the
          43 line mode.
       On exit, restores 25 line mode if you entered GoodLook in the
          25 line mode.
       Many invoke either the 25 or 43 line mode "on the fly" while
          viewing files with the [E]GA key.

3.5 to 3.9:  (maintenance releases, limited distribution)
      Fixed problem when running GoodLook w/no arguments (would say
       "file c:\" does not exist, vice "Syntax is:..."
       Renamed GoodLook.com to GL.com, which is what I am sure was the
       first thing that any user of this program would do!!
       Changed the overlay search routine to first look for the overlay
       in the dir from which GoodLook was run.  Thanks to Karl Brendel
       for the tip that the run location is at the end of the environment
       string!

3.4   Fixed file handling problem when, filenames entered one at at time.
      - Now adds current location if no drive\path entered
      - *.* is now equivalent of * for file 2 = file 1 (just filename)
      - easier to detect duplicate filenames entered
      - Updated DOC to show rules for filenames (\ must be on end of
         path, etc.)
      Many thanks to Jack Kilday for inadvertently Beta Testing this for me,
      discovering and reporting the problems clearly enough for me to find them.

3.3   Maintenance Release to replace 3.2, which may have had a garbled overlay
     file included.

3.2   Fixed minor typos.
      Fixed problem with long paths causing the program to blow up.
      Fixed config, so that when returning from config, rewrites bottom lines
     in new colors.
Thanks to Karl Brendel for the above tips!!
      Fixed initialization so that it only looks for the Overlay if it does
     not exist in the default location.
      Added a [Z]oom indicator on bottom to show how to Zoom and to show
     what was zoomed.

3.1   Added a Zoom feature.  You can Zoom either of the files up to the
    full-screen mode.
      Added the Single file mode to use GoodLook as a file viewer.  Uses the
    Zoom function Zooming File 1.

3.0   Added optional flag for WordStar(tm) mode, which strips high bits.  The
    flag can be entered on the command line else config file sets default.
      Added the ability to stop the search for the Next Mismatch by pressing
    any key during the search.  This is a fast way to move forward.
      Fixed a bug in reading in lines, one file or the other would end up
    with blank lines, wasn't going back to the file and getting more when
    it should.
      Added individual file 9 line scroll, using Control plus the 1 line
    scroll keys: Home, End, PgUp, PgDn.  Had to change Top of File
    function to ^T from Ctrl Home.

2.9   Changed the margin from 73 to 80 to get more of a line on the screen.
      Removed the --> from the front of a wrapped line.
      Moved the line number from on each line to the fname line.
      Added the ability to customize the colors of the highlighted lines;
      added a normal display for the highlighted lines.
      Thanks to comments from Tim Penner of Wichita, KS.

2.8   Fixed a still minor bug as in 2.7.
      Added the ability to enter *.BAK as file 2 to use the filename of
     file1 with the new extension (filename.bak).  This includes the
     ability to use b:*.bak or b:\newpath\*.bak also.

2.7   Released immediately to fix a bug in the display function:  it would
     display only file 1 in both windows after a search.

2.6   Fixed the color option so that it shows the colors as they are
     installed.
      Changed the Color option to Configuration option since it there are
     several option to change.
      Added a direct to video write routine to speed up the display when
     scrolling by 10 lines and when displaying help screens.

2.5   Fixed a minor bug when shifting from Parallel to Opposite
     in the Configure routine.
      Added the Top of File option to return to the top of both files.

2.4   Added an optional scrolling mode which scrolls file 1 in same dir as 2
     Also puts the compared lines right next to each other
     Added Scroll Mode to variable, clonable options.
      Fixed the directory error-handling so that when the DOS message "Place
     Disk B in drive A..." occurs it doesn't blow up my screen.
      Changed the line numbering scheme so that they match the actual
     line nos in a file.  Wrapped lines are shown as -->
      Added help screens [F1] in the configuration function.

2.3   11/9/86. Added option to have a Config file to override default config.
      Removed the bottom line garbage which remained at exit.
      Eliminated CursorOff and On temporarily to avoid problems with
    compatible and EGA card.

2.2   11/5/86. Added a Customize option to choose the flashing or highlighted
    lines.
      Added customize option retrace testing for IBM CGA.  Change to
    fast for non-IBM cards.

2.1   Fixed some bugs parsing filenames provided as command line
    parameters.
      Fixed the end of file routine to show consistently when at end
    of file.
      Fixed the Drive change routine to move to the logged subdir on
    the new drive, rather than the root drive.
      Fixed the DriveTest routine.  It would automatically change the
    tested drive to the root directory.

2.0   Added File directory routine to display files on the drive (as well
    as the ability to move from drive to drive) and View a file prior
    to choosing.

1.9   Fixed a bug when two identical filenames were entered on command
     line.
      Added a prompt to remind you to enter a drive only to use the
    same filename on a different drive.

1.8   Added a Color setting option on the fly and clone routine.

1.7   Added support for a monochrome adapter.

1.6   2 October 1986.
      Defined synonym keys on the numeric keypad to make it easier to
    scroll through the files, response to George Sullivan's critical
    review.
      Added full path/filename support.

1.5   30 September 1986
      Fixed continuous loop when two illegal files are entered.  In fact
    fixed the whole filename entry routine.
      Added option to enter just a drive name for the same filename.
      Change display type to default console vice color display. Thanks to
    Karl Brendel of Hutchinson, KS for this tip!!
      Fixed it so it would search till end of file.

1.4   Fixed the line numbers so that more than 999 lines can be displayed.

1.3   Added prompt for a file if not entered or if file not exist.
      Added the numerals alone as synonyms for the function keys.
      Added the [Esc] key to skip the commercial on get help.
      Fixed the information line to show all 10 function keys.
      Removed the reset video mode line.
      Fixed a few bugs with beginning of file/end of file.
      Put the filenames at the top and bottom of the screen so they
      would not interfere with the compare and so that very long
      pathnames\filenames could be accommodated.

1.2   Added a find next key, scroll both, and scroll both by a page feature.
      Also fixed it so that it loads 300 lines at a time vice 100.

1.1   Added single key to scroll forward or backward. New windowing techniques
      to speed up showing window.

1.0   Initial release.
