- 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).
