DoubleTake
by John L. Dove III
Version History
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 cod
