- This file contains a summary of changes made to Back & Forth. They are listed
- in reverse order, the most recent additions and modifications listed first.
-
- ──────────────────────────────────────────────────────────────────────────────
- Version 1.31 June 5, 1990
-
- A) Notes:
-
- * Added a program called BNFCNVT.COM which will convert the B&F variables
- file (BFVARS) to new format. If you try and run BNF or BNFHIGH, and you
- haven't run the convert program, you will be informed to do so. If you
- try and use the BFVARS file with an earlier version of B&F after it has
- been converted, B&F will report the B&F variable file has been corrupted
- and it will be reset (therefore, do NOT run an earlier version of B&F
- with a converted BFVARS file)!
-
- B) Bug fixes first:
-
- * SWITCH program restarted a partiiton if it was already active.
-
- ──────────────────────────────────────────────────────────────────────────────
- Version 1.30 June 1, 1990
-
- A) Bug fixes first:
-
- * Screen blanker didn't work when screen enhancer programs like UltraVision
- were loaded.
- * Cut/paste default hot keys weren't initialized correctly and required the
- user to set them through setup.
- * Fixed "Not enough file handles" error message gotten when Word Perfect
- was run when 4DOS was used as the command interpreter!
- * Fixed a bug which caused several different types of errors on various
- systems (speeded up clock, the left shift stayed on, etc).
- * Back & Forth didn't work with FILES loaded high or DOS 4.x SHARE command.
- * Video save files were not deleted all the times.
- * Back & Forth now restores EGA/VGA graphic screens more precisely.
- * Mouse cursor left a bald spot on graphic screens.
- * Fixed delay caused when MOUSE driver is loaded globally. The delay on
- PS/2s was unbearable!
- * Clock and swapping message were incorrectly shown when swapping a
- partition that didn't have the active page set to 0!
- * Back & Forth NEVER worked satisfactorily if you loaded PC-PAINT
- Brush 4.0+ and then swapped to another partition.
-
- B) Enhancements:
-
- * Changed initial screen delay from 30 seconds to just requiring user to
- press a ramdomly generated key.
- * Increased maximum swap size allowed on individual drives to 16MB. Please
- note though that B&F won't allow more the 20 x largest task size to be
- allocated. The 20 represents the current maximum # of tasks.
- * The cut mode now allows mixing of format attributes: each time you do a
- cut, Back & Forth stores the cut text with the current cut format.
- * Added two new toggles to Cut/Options menu: stripping of leading and
- trailing blanks.
- * Cut mode can now cut any size text screen as long as it is 80 columns or
- wider.
- * Added shadowing to most windows in various B&F modules.
- * Added 2 letter/number id byte to each program definition. This will be
- used for future compatibility with other programs such as StacKey. This
- also allows quick Desqview(tm) like program execution on the main menu!
- * Added a map of already defined hotkeys in the hotkey editor.
- * Enhanced mouse support to allow users to load mouse driver locally in
- individual partitions. Prior versions of B&F would only save/restore
- mouse condititions if the mouse was loaded globally. We recommend the
- user to load the MOUSE.COM control program high if possible otherwise
- to run it individually in partitions where a mouse is needed
- (thus allowing partitions that don't need the mouse to have 5 or so
- more k of memory)!
- * Changed way hot keys are assigned to give a wider range of keys. Please
- note though the following keys/key combinations will NOT be allowed:
-
- 1) Ctrl-Alt-Delete
- 2) Ctrl-Up
- 3) Ctrl-Down
- 4) Any key combination using one of the extended keyboard cursor keys.
-
- C) New features:
-
- * Added AUTOLOADing of programs! Back & Forth has two types of automatic
- switching:
-
- 1) Waiting for keyboard request - This option will switch to the next
- task as soon as the loaded program requests any keyboard input. This
- option should be used for most programs as it will be the most sure
- and most likely the fastest (a program has to be fully loaded to be
- requesting keyboard input!).
-
- 2) Timed delay in seconds - This option will count down a specifed
- number of seconds and then switch to the next task. This option
- should be used for programs that don't request any keyboard activity
- after being loaded (I can't think of an example)!
-
- * The # of screen lines can now be toggled between 25/43/50 lines on
- systems with EGA/VGA video cards. This is done under the Options menu
- in the setup module.
- * Added a small program called SWITCH.COM that allows the user to switch
- partitions from the command line of a partition.
- * Added EMS memory cleanup module - Back & Forth now performs a
- mark/release like action on all EMS handles associated with a task
- after it is closed. So, if a TSR or other program using EMS locks up or
- does not relinquish EMS memory, you can pop back to B&F and close the
- task. This routine will then remove all vestiges without trouble. This
- is also used to remove 4DOS without using EXIT to close the partition.
- * Back & Forth can now be loaded high and thus use less than 1k of memory!
- * Added swapping to extended memory if the HIMEM.SYS driver is loaded.
- * Added user initiated screen blanker. Pressing the '5' key on the numeric
- pad will automatically blank the screen.
- * Added two new B&F task movement hotkeys:
-
- <Ctrl-UP> will goto to the preceeding open task. If the current task
- is the first opened, then the last task will be come the
- foreground task.
- <Ctrl-DOWN> will goto to the next open task. If the current task is the
- last opened, then the first task will be come the foreground
- task.
-
- * Keyboard click. It can be toggled on/off under keyboard item in setup
- module.
- * FASTKEY! (keyboard accelerator). Set delay and rate under keyboard item
- in setup module.
- * Changed way B&F works with UltraVision as discuessed with one of its
- authors, John Jurewicz, to assure better compatibility with some of UV's
- advanced features.
- * Added UV mode support for B&F and individual programs! This requires UV
- to be loaded globally!
- * B&F now allows the user to specify an environment size for each task. This
- is done in the program setup editor.
-
- * And much, much, more!!!!
-

- Version 1.12 March 28, 1990
-
- -A) Bug fixes first:
-
- * Screen wasn't restored correctly on monochrome systems.
-
- B) Enhancements:
-
- * B&F is about 1-2k smaller!
-
- C) New Features:
-
- * Added new version of B&F kerenel called B&FEGA.EXE. This version of B&F
- is for people who have EGAs. All other video cards should use B&F.EXE.
- * Added a small TSR called B&FFIRST.COM. If you are using programs like
- UltraVision that enhance the display, you should run B&FFIRST before UV.
- This will allow Ultravision to be loaded HIGH and globally!
- ** Note ** B&FFIRST can be loaded HIGH.
- * Added a new hotkey called "B&F Super Hotkey!". This key should be used
- to call up the B&F menu when all other hotkeys fail. This was added for
- programs that take over the keyboard and don't give control back.
-
- The super hotkey is <LSHIFT>-<Ctrl>-<Alt> simultaneously!
-
- ──────────────────────────────────────────────────────────────────────────────
- Version 1.11 March 22, 1990
-
- * Minor bug fix: DOS critical error handler wasn't always restored correctly
- when switching directly between tasks.
-
- ──────────────────────────────────────────────────────────────────────────────
- Version 1.10 March 21, 1990
-
- A) Bug fixes first:
-
- * Better restoration EGA/VGA palette,
-
- * Command stack sometimes went flakey after it filled up
-
- B) Enhancements:
-
- * Added better support for running programs on networks.
- * Inactive programs can now be loaded directly be pressing the program's
- defined hot keys,
- * Maximum # of tasks has been increased from 9 to 20.
- * TSR partitions are now easier to setup by defining a program with the
- "STAY AT DOS" option.
- * DOS commands as well as 4DOS aliases can now be executed as programs!
-
- C) New Features:
- * Added direct support for 4DOS.
- * Added support for Ultra Vision (follow the directions in the B&F doc
- file)!
- * Added a cut/paste module.
- * Added a background clock.
-
- ──────────────────────────────────────────────────────────────────────────────
- Version 1.01 February 28, 1990
-
- * Changed way B&F passes environment. In version 1.00 B&F used the DOS master
- environment block but under some versions of DOS it couldn't find it.
-
- ──────────────────────────────────────────────────────────────────────────────
- Version 1.00 February 27, 1990
-
- * Official release of Back & Forth into Shareware!
