by JP Software Inc., P.O. Box 1470, E. Arlington, MA 02174 USA, (617)

Greetings, and thanks for trying 4DOS!

This file contains a variety of information you should read before using
4DOS, including:

* About this version * Technical support
* Files included with 4DOS * Bulletin board support
* Installation instructions * Shareware and ASP policies
* Upgrading from 4DOS 5.0

If you have tried a shareware copy of 4DOS and want to place an order,
see the product and ordering information in the file ORDERINF.DOC, or
call us at (800) 368-8777 (USA only, orders only please!) or (617) 646-
3975. An order form is included separately in the file ORDER.FRM. JP
Software also offers Take Command, an exciting new command processor for
Windows and Windows NT, and other products which complement 4DOS, like
the 4DOS Utility Disk; the Semware Editor Jr. for ASCII files; the
multiple configuration utility BOOT.SYS; and the Personal REXX language.

For complete installation instructions, see page 3. These instructions
cover installation procedures for both new users and those upgrading
from a previous version of 4DOS.

The license agreement which governs your use of 4DOS is included
separately in the file LICENSE.DOC. Please read it before ordering.
The text is written in plain English, and clearly explains your rights
and responsibilities as a user of 4DOS. For more information on the
shareware system under which you obtained this copy of 4DOS, see page 6.

This file, like all our ASCII documentation files, is formatted at 58
lines per page, and contains form feeds and page footers. It can be
viewed with a file viewer such as the 4DOS LIST command, or printed on
most PC printers using the command:

copy readme.doc prn

Printing it with a program that formats the pages is not likely to work
due to the formatting included in the file.

About This Version

Be sure to read the installation instructions in this file before
installing 4DOS 5.51!

Version 5.51 is a maintenance release of 4DOS. It coincides with
similar maintenance releases of our other command processors: 4OS2
version 2.51, 4DOS for Windows NT version 2.51, Take Command/16
version 1.01, and Take Command/32 version 1.01.

The only substantial change in this version is the addition of long
filename support for Windows 95. All other changes are relatively
minor. For a complete list of changes be sure to read UPDAT551.DOC --
BEFORE you begin using version 5.51! If you're a new 4DOS user, you
can skip UPDAT551.DOC.

For information on using 4DOS with Windows 95, see the "Win95" topic
in the 4DOS online help (you can retrieve this information quickly
with the command HELP WIN95 at the 4DOS prompt).

If you missed previous major upgrades, such as version 5.0 or 5.5,
you may want to obtain a copy of the corresponding update files
(UPDAT50.DOC and/or UPDAT55.DOC) so you know what was new in those
versions. These files are available in our CompuServe, BBS, and
Internet download areas (see page 6 below) as UPDAT50.ZIP and
UPDAT55.ZIP, and printed copies can be obtained by contacting our
Customer Service department.

Files Included with 4DOS 5.51

Please note that the way your copy of 4DOS is "packaged" will vary
depending on the distribution method (5.25" disk, 3.5" disk, or on-
line). In general there will be three 5.25", 360K disks, or two 3.5"
720K disk. On-line copies will be in one .ZIP file, with a name like

You can also download the 4DOS, 4OS2, and 4DOS/NT Reference Manual
(the file is named REFMAN.DOC, and is typically stored in the file
JP4REF.ZIP). This is a large file and much of the same information
is available in the online help system, but we do make the ASCII
version of the manual available for those who wish to download it.

If you have a 4DOS 5.0 Reference Manual and have not ordered an
upgrade to version 5.5 or 5.51 with the printed Addendum Manual, you
can also download the Addendum -- look for the file JP4ADD.ZIP.

ZIP files distributed by JP Software will display the message
"Authentic files Verified! # VHJ325 JP Software Inc." when they
are unzipped. If you do not see this message, the ZIP file you are
using has been modified. This does not necessarily indicate a

4DOS 5.51 [8-22-95] README.DOC page 2

problem, but it does alert you to the fact that the file has been
changed since it was created by JP Software.

4DOS.COM 4DOS program file
4DOS.DOC ASCII copy of the 4DOS Introduction and

Installation Instructions

(These instructions do not cover diskette installation, because when
4DOS is installed from diskette this file is not visible until after
installation is complete.)

4DOS 5.51 [8-22-95] README.DOC page 3

Whether or not you presently have 4DOS installed, create a new
directory for 4DOS 5.51 (do not install it in the same directory as a
previous version of 4DOS). Decompress your downloaded 4DOS 5.51
files into this directory. You can print any 4DOS documentation file
by copying it to the printer with the COPY command.

Please note that the 4DOS Introduction and Installation Guide is
about 80 pages long, and the Reference Manual is over 380 pages long!
If you don't want to print these files they can be viewed on-screen
with a file viewer such as the 4DOS LIST command. Most of what's in
the Reference Manual is also available in the 4DOS help system.

For a guided tour of 4DOS features see the instructions in TOUR.DOC.
To install 4DOS completely, follow the manual installation
instructions in Chapter 1 of 4DOS.DOC, disregarding the discussion of
extracting files from the diskettes.

Be sure you have a bootable DOS floppy disk (as described at the
beginning of Chapter 2) before installing 4DOS on your system. This
is not because 4DOS is likely to cause trouble. It's because a
mistake in the system startup files (CONFIG.SYS and AUTOEXEC.BAT), or
a power failure or other disturbance during installation, could
prevent your system from booting properly. While such problems are
rare, any time you modify CONFIG.SYS or AUTOEXEC.BAT you should have
a bootable floppy disk handy so you can recover if necessary. (If
you have MS-DOS 6 or above, or Windows 95, you can often restart a
misconfigured system or one with damaged startup files, even if
you've forgotten to make a bootable floppy disk. Just press F5 -- to
bypass all startup files -- when you see the "Starting MS-DOS ...",
"Starting PC-DOS ...", or "Starting Windows 95 ..." prompt. See your
operating system documentation for more details on the effects of F5
and other boot control keys.)

Upgrading from 4DOS Version 5.5 to Version 5.51

Be sure to go over the changes in version 5.51, in the file
UPDAT551.DOC, before you start using it. 4DOS 5.51 can be run in
"test drive" mode over previous versions of 4DOS, so you can test the
new version before fully installing it. 4DOS 5.51 should always be
installed in a different directory than any earlier version of 4DOS.

To upgrade from 4DOS 5.5 to version 5.51, make the following changes
in your system configuration:

* Modify the SHELL= line in CONFIG.SYS to reflect the new
directory where 4DOS.COM is stored. Make a similar
modification to any SET COMSPEC statements you have in
AUTOEXEC.BAT or other batch files.

* Modify any line in AUTOEXEC.BAT which loads KSTACK.COM to
reflect the new directory where KSTACK.COM is stored.

4DOS 5.51 [8-22-95] README.DOC page 4

* If you keep any 4DOS startup or exit files (4DOS.INI, 4START,
or 4EXIT) in your 4DOS directory, be sure to move or copy the
old files into the directory where 4DOS 5.51 is stored. (If
the files are in the root directory of the boot drive they do
not need to be moved.) Also be sure to modify any path
information in these files to reflect the new directory for
4DOS (for example, if you have a HelpPath directive in 4DOS.INI
you may need to change it to point to the new directory for the
4DOS 5.51 copy of the 4HELP program).

* If you use OS/2 2.x or above, be sure that any DOS_SHELL
settings you have explicitly set to 4DOS in your DOS session
objects are modified to reflect the new directory where
4DOS.COM is stored. You can also highlight the DOS_SHELL
setting and click on the Default button; this will set the
command processor for the object to whatever is specified on
the SHELL= line in CONFIG.SYS. See your 4DOS Introduction and
Installation Guide for complete details on using 4DOS with

* If your first purchase of 4DOS was version 5.0 or 5.5 you can
"brand" your copy of version 5.51 and convert it to a
registered copy. To do so, copy the BRAND program from 4DOS
version 5.0 or 5.5 into the same directory as the version 5.51
files, and run it with the command BRAND. Follow the on-screen
instructions to install your name and serial number into 4DOS.

The information needed to brand your copy is on the small blue
or yellow "Brand ID Card" which came with your copy of 4DOS.
If you cannot find this card with your branding codes, you can
order a replacement from JP Software for $5.

If your first purchase of 4DOS was version 4.0 or earlier you
will not be able to brand version 5.51. Instead you must order
an upgrade from JP Software. You can use your downloaded
shareware copy of version 5.51 while you wait for the upgrade
to be shipped to you.

See the ORDERINF.DOC and ORDER.FRM files for more information
on upgrades and our upgrade policies.

Once you've made these changes, you can reboot your system and you'll
be running 4DOS 5.51.

Technical Support

We support 4DOS in our own CompuServe area, section 10 of the PC
Vendor B forum (GO PCVENB). If you are not currently a CompuServe
subscriber, consider a special offer CompuServe has made to 4DOS
users: call 1-800-848-8199 (outside the US and Canada call 614-457-
0802) and ask for operator 178 to receive a free CompuServe

4DOS 5.51 [8-22-95] README.DOC page 5

introductory membership, including user ID, password, and a $15
connect time credit.

For technical support on the Internet send mail to
[email protected]

Support is also available by phone (617-646-3975), fax (617-646-
0904), and mail (JP Software, PO Box 1470, E. Arlington, MA 02174).
Telephone support hours and availability may vary depending on our
current staffing pattern and workload; there may not always be a
support representative available when you call, in which case we will
take a message and call you back. We return calls as soon as
possible, and our normal policy is to return all calls within at most
24 hours (weekends and holidays excluded).

Bulletin Board Support for 4DOS

4DOS product support is always available on our support BBS, Channel
1 in Boston. Channel 1 is an independent BBS (not operated by JP
Software) which has generously offered to provide a home for 4DOS BBS
support. Phone 617-354-3230 to access Channel 1 at 2400 - 14,400
baud (no parity, 8 data bits, 1 stop bit).

If you have access to a local bulletin board which is a member of any
of the major BBS networks (RIME / PC Relay, ILink, or FidoNet), you
can discuss 4DOS with other users, and obtain limited support from JP
Software, by leaving messages in the network's 4DOS conference.

Downloading 4DOS Files

You can download 4DOS upgrades and other files from CompuServe or the
Channel 1 BBS (see above), or from our Internet ftp site. To
download files from CompuServe, go to the PC Vendor B forum (GO
JPSOFT or GO PCVENB) and look for the files you want in Library 10.
On Channel 1, join conference 5 and then download the files you need
(as long as you join conference 5 before downloading you will be able
to download 4DOS files even if they appear to be too large for your
remaining time on the system). On the internet, download the files
you need via ftp from, directory /vendors/jpsoft (for
general JP Software files) or directory /vendors/jpsoft/4dos (for
4DOS-specific files).

Shareware Copies of 4DOS

If you obtained 4DOS from a shareware disk vendor, an on-line
computer service or bulletin board, a friend or colleague, or another
similar source, you have an unregistered (trial) copy. As the
copyright holder for this software, JP Software allows and encourages
you to use this trial copy without charge for a limited period of

4DOS 5.51 [8-22-95] README.DOC page 6

time, under the terms of our license agreement (see LICENSE.DOC).
After this time is up, you must purchase (register and pay for) the
product to continue using it.

This method of distribution is known as shareware. It allows you to
determine whether the product meets your needs before you pay for it.

Payment of the shareware registration fee for 4DOS entitles you to a
complete copy of the product with typeset-quality printed and bound
manuals; the ability to download an upgrade to the next major release
of the product; continued technical support via electronic mail or
telephone; and a subscription to "The Prompt Solution", JP Software's
customer newsletter.

Association of Shareware Professionals

The authors and publisher of 4DOS are members of the Association of
Shareware Professionals (ASP), an organization formed to strengthen
the future of shareware. Its members, all of whom are programmers
who subscribe to a code of ethics, are committed to the concept of
shareware as a method of marketing.

The ASP sets standards for its members and their shareware products
which provide that programs produced by ASP members must be fully
documented, non-crippled, and offered with at least a minimum level
of support. It also sets standards for shareware disk vendors and
provides information to the public about shareware.

ASP Ombudsman Statement

JP Software is a member of the Association of Shareware Professionals
(ASP). ASP wants to make sure that the shareware principle works for
you. If you are unable to resolve a shareware-related problem with
an ASP member by contacting the member directly, ASP may be able to
help. The ASP Ombudsman can help you resolve a dispute or problem
with an ASP member, but does not provide technical support for
members' products. Please write to the ASP Ombudsman at 545 Grover
Road, Muskegon, MI 49442-9427 USA, FAX 616-788-2765 or send a
CompuServe message via CompuServe Mail to ASP Ombudsman 70007,3536.
