------------------------------------------------------------------------------
This document contains changes and bug fixes of interest to existing users
(most recent first). New users may disregard it.
------------------------------------------------------------------------------
8/31/86
Bug fixes: Extended ASCII code when Ctrl keys hot no longer hangs system;
command stack playback with F7 sometimes returning same entry repeatedly,
corrected.
8/30/86
Screen save file names now added to command stack, releasing Alt-6/Ctrl-F;
ASCII table transferred from Alt-3/Ctrl-C to Alt-6/Ctrl-F; Alt-3/Ctrl-C
released to avoid conflict with DOS definition of Ctrl-C. Alt-10/Ctrl-J
transferred to Alt-14/Ctrl-N and Alt-13/Ctrl-L transferred to Alt-15/Ctrl-O to
reduce chance of accidental invocation.
"A" switch definition changed to allow Ctrl sequences only as hot keys (as
well as Alt sequences only, or both, as before). See documentation.
8/20/86
Screen save to disk can now function during DOS disk operations, allowing
faster repeats; ASCII table now written direct to screen.
8/16/86
Bug in calculator handling of 2 to a negative power corrected.
7/6/86
F7 and F8 can now maintain a separate stack within programs. See
documentation.
7/2/86
Bug fixes: logo once again is displayed while a command is pending; occasional
system hang on Alt-8 function corrected.
7/1/86
Alt+keypad sequences may now be substituted for by the ASCII-equivalent
Ctrl+letter key combination, unless the 'A' switch is set. (See "HOT KEYS" in
the documentation.) This is to get around the problem that some clones,
notably Leading Edge, do not support K9's method of distinguishing Alt-keypad
combinations from other, but ASCII-equivalent, combinations. Of course, this
will cause a new problem if users on such machines are running WordStar.
Tough. Any programmer still using WordStar deserves a little grief. [This
has been further improved--see notes of 8/30/86.]
6/23/86
'E' switch added to pause system if a DOS errorlevel of at least the
switch value (other than 0) is being returned by any non-resident process to
its parent.
5/26/86
Alt-7 command set now defines F as form feed. F's original function is now
assigned to M.
5/23/86
Calculator handling of whole portion of number results has been changed.
Output is now the least significant 32 bits of any value in the range (2^63-
1)..2^63-1. The most important effect of this is that unsigned values in
the range 2^31..2^32-1 are now handled without reporting an overflow.
(Values with bit 31 set may be positive or negative; this must be inferred
from the sign of the floating point result.) Overflow now appears as 0
instead of 80000000H--of course 0 may also be valid.
'B' switch added to advise K9 that a BW monitor is in use with a color card,
avoiding unreadable displays in some situations.
5/7/86
K9 now detects the presence of an EGA card automatically, enabling the screen-
aver function to work.
4/9/86
Bug of calculator printing 0.00000000000000e<whatever> for values rounding
up to 10 to an integer power corrected.
4/7/86
K9 now has an option to allow the user to require that some designated
control-key-function-key combination precede a K9 function request. This is
to get around conflicts with other resident utilities or programs that want
to define the Alt-keypad sequences themselves. See the "K" switch
documentation.
