Back & Forth
* * * * * * * *
This file documents the changes made to Back & Forth since the manual has
been written. This also lists some hints that may help you use this program.
A separate file called INSTALL.B&F details the steps to be taken to install
Back & Forth on your system, including an example showing how to use the
B&F Installation procedure to set your swap areas. Read this file!
──────────────────────────────────────────────────────────────────────────────
ENVIRONMENT VARIABLE SETUP:
After you have extracted the files from the compressed file, please print the
manual and read it!
SET B&F You must set the B&F environment variable before running Back &
Forth or the program will not run. The B&F environment variable
informs Back & Forth where to find its overlays and create/save
its data files. If not set before B&F is run, an error message
stating "B&F environment variable is not set" will be shown on
the screen and the program will not be loaded.
To set the B&F environment variable, you may either type the
SET command at the DOS prompt each time B&F is run or you may
add the SET command to your AUTOEXEC.BAT. It should appear as
follows:
SET B&F=drive:\path
where drive:\path is the drive & directory where Back & Forth
is stored (e.g., SET B&F=C:\B&F)
B&F Directory:You must be located within the B&F directory before running
the program. By requiring this, 1.5 k of memory is saved for
your use. Most of our users have told us "The more memory
available, the better". So, we figured that you probably had
better things to do with the memory than to provide a change
directory command for initially running B&F. Once the program
is in memory, the directory can be changed.
Both of these are taken care of when you use our HD-SETUP program provided
with Back & Forth. This creates either one or two batch files that
automatically set up this information. Once these files are created, copy
them to a point along your path and use them to execute Back & Forth.
FILES You may need to set your FILES value to a higher value. The
minimum value of the FILES statement should be set to 40,
plan on 8 files per task run within Back & Forth.
Swapping to extended memory:
Back & Forth may be configured to swap to extended memory if the HIMEM.SYS
device driver is loaded.
HIMEM.SYS is an installable device driver which conforms to the XMS (eXtended
Memory Specification) Version 2.0. It allows MS-DOS programs on 80286 and 80386
systems with extended memory to access the extended memory using a standard,
machine independent manner.
If other extended memory programs are also being loaded which do not use the
XMS interface to manage the extended memory, they should be configured to leave
at least 64KB of extended memory free. To use HIMEM.SYS, with your computer,
you need the following:
- An IBM PC/AT or PS/2 or compatible computer.
- An extended memory board.
To install HIMEM.SYS, include a command line of the following form in your
CONFIG.SYS file:
DEVICE=[d:][path]HIMEM.SYS
During installation, a message similar to the following will be displayed:
HIMEM: DOS XMS Driver, Version 2.02 - 7/19/88 Copyright 1988, Microsoft Corp.
HIMEM.SYS must be installed before any other device drivers that make calls to
it. Thus, any device driver which uses XMS calls should be loaded after
HIMEM.SYS.

The above should get you going! If you can't get the program running, please
don't hestitate to call me at (512) 670-1061 for aid. Please note, if we are
not available, please leave your name on the answering machine and call back
later.

Shareware LIMITATIONS:
There are no limitations inherent in the unregistered version of Back & Forth;
but there are a few inconvenient reminders of the necessity of registration if
you use it often.
-Back & Forth displays a screen initially reminding the user of his obligation
to register the software if he/she uses it. We do not view this as a major
annoyance as most users will load B&F only once each day and then use it for
an extended period of time.
-Back & Forth then forces a task switch after every 60 minutes of unregistered
use to the Back & Forth menu and then reminds the user of his/her obligation
to register the software if he/she uses it. Thus you should NOT download or
upload files or run any programs within a B&F partition which cannot be
interrupted!
We do not want to cripple our software by leaving out major features, as other
shareware authors have chosen to do. We do hope that you will register your
copy if you find our software useful.
──────────────────────────────────────────────────────────────────────────────
Benefits of Registration:
-Key file to remove shareware annoyances placed in Back & Forth. This key file
will be good for all future versions of B&F (updating can be as easy as down-
loading the latest version from our BBS)!
-Phone support from the programmers themselves!
-Printed manual.

Helpful hints:
* Loading HIGH:
If you experience problems with loading BNFHIGH, please read the trouble
shooting section in the manual. If you are still unable to resolve problem,
please contact us voice or on CIS and let us help you. We have been able
to resolve most people's problems within 5 minutes (but we cannot help you
if you don't let us know)!
* To all users using SUPERPCK.COM (Super PC-KWIK)
If you experience exception 13 problems when loading B&FHIGH, make sure
to turn off advanced disk writing (/H-). You may/may not have to do this,
but it has resolved some users exception 13 problems.
* You should have FILES in your config.sys file set to at least 50 or 60.
* If you are running 4DOS, DO NOT LOAD FILES HIGH! This problem is with 4dos
and not with B&F! Also if you have EMS memory and wish to have 4DOS use it,
use the 4DOS environment variable to use EMS memory rather than XMS:
SET 4dshell=/S:E
If you don't, B&F cannot cleanup 4DOS' use of EMS memory.
Do not use the /u option. B&F will not be able to release high memory
if 4DOS allocates it from the XMS memory pool.
* Video problems....
1) B&F currently does not support Hercules graphics. All hercules cards
are treated like monochrome cards. This also includes graphic screens
on the Compaq portable III/386 when in 640x400.
2) Since not all EGA/VGA cards are alike, if you have problems restoring
text base screens, we highly recommend you purchase UltraVision from
Personics, Inc. UV enhances B&F's compatibility with the zillions of
EGA/VGA cards.
3) B&F currently doesn't support graphics resolutions higher than
800x600x256.
An upcoming release will take care of problems 1 & 3.

Support/bug reports/helpful suggestions:
A convenient way for you to communicate your ideas and inform us of possible
problems is by leaving us a message on our RBBS at (512) 670-0954.
Or, call us/FAX us at (512) 670-1061 with your problems.
If you want to make suggestions about bettering the program, please either
leave a message on our RBBS or write us a letter. It's not that we don't like
talking to you about your good ideas. It's just a lot easier for us to keep a
folder of ideas and planned program additions with the names of the people
who have suggested them (especially if you knew the way Shane keeps his
telephone notes and the rest of his desk organized).
Thanks,
