STACK REVISION HISTORY
======================
Version Changes
------- -------
2.0 Complete rewrite
2.1 - Modified so that when auto window display is enabled the
command line doesn't contain an initial command
- Added 'sort' options for command stack (these options are
set using the setup program):
No sort - default
Move Forward - when a command is executed it is moved
forward to the end of the command stack. The effect of
this is that the most used command drift towards the end
of the command stack and the others fall of the top
Delete Least Used - when more room is needed in the
command stack rather than delete the command on top the
oldest, least used command is deleted
Both - enables both Move Forward and Delete Least Used
- Allow a command (in the command stack) to be recalled by
typing the first few letters and pressing the search key.
The number of characters used in the search and the trigger
key can be set using the setup utility. This facility can
also be disabled using the setup program.
- Stack now makes a more thorough search to see if it has been
loaded before to prevent multiple loading.
- The same error message is now used to indicate an error
updating STACK.COM or a data file (ie. for the Alt-w, Ctrl-w
and Ctrl-r commands)
- The setup program, STACKUP, now accepts a full pathname on
the command line to tell it where to find the STACK command
file to modify. In addition if you have renamed the .COM
file then using STACKUP followed by the modified filename
will cause STACKUP to record the modified name in the
command file so that Alt-w will work correctly.
- AND YES A BUG ! Version 2.0 didn't correctly check the last
character when checking if a command was already in the
stack. Now it does.
2.2 - Didn't get the fix of the bug mentioned above quite right
but I'm fairly sure I've got it this time.
- provided the option of using a file name stored inside of
STACK for Ctrl-W and Ctrl-R commands instead of having to
enter a file name on the command line
- provided room to store upto 30 characters for the path and
file name used for Alt-W, Ctrl-W and Ctrl-R commands
- can now prevent repositioning of command line if it would
have clashed with the window display. If the command line
is not repositioned then it is temporarily shortened to
prevent it overwriting the window.
2.3 - had another go at stopping the command line bumping into the
window (and got it right this time !?)
- stopped output of message on successful read (Ctrl-R)
- corrected minor bugs with delete of character at end of line
and using the back tab key for searching
- re-arranged a few things and reduced the size of STACK by a
few hundred bytes
- added a /v option to use if the screen display behaves
strangely when running STACKUP
- Third time lucky ? I thought I had fixed the bug that
allowed duplicate commands to sneak into the stack but I
have had reports to the contrary. Dare I say I've got it
this time ?
2.4 - Regards the last question - NO ! Well not quite, in some
situations when the "bring forward" sort option was selected
the second last command would duplicate. Thanks to some
help from Jeff Bowles I may have got it this time.
- At Jeff Bowles' suggestion I added an option to allow F3 to
act the same as the UP key.
- Changed STACKUP a little and fixed the disappearing cursor
on exit
2.5 - Changed to keep usage information when command copied
forward in command stack
- fixed STACKUP to allow modification of F3 option
2.6 - Recently I spent six weeks away from home. When checking
STACK on my return I found I had two different files labeled
version 2.5 ! Version 2.6 is primarily to remove this confusion.
