Greetings, and thanks for trying 4OS2!
This file contains a variety of information you should read before using
4OS2, including:
Release notes (page 2), includes:
* Files included with 4OS2
* Installation instructions
* Technical support
* BBS support
Using 4OS2 with other software (page 7)
Changes in 4OS2 since version 1.0 (page 8)
If you have tried a shareware copy of 4OS2 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. The order form is included separately in the file ORDER.FRM.
The license agreement which governs your use of 4OS2 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 4OS2.
This file 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 or
4OS2 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.

Release Notes
-------------
4OS2 Version 1.11:
This is the official release of 4OS2/32 and the first major update to
4OS2/16 version 1.0 (previously named simply "4OS2").
If you have been using 4OS2 version 1.0, or 4OS2/32 version 1.1, see
page 8 for changes in version 1.11.
4DOS:
This file and most other 4OS2 documentation refers frequently to
4DOS, JP Software's award-winning command processor for DOS. If you
are not familiar with 4DOS we suggest that you obtain a copy
(available from the same place where you got 4OS2), and if
appropriate, install it on your system before or along with 4OS2.
4DOS and 4OS2 are complementary and offer the same functions in your
DOS and OS/2 sessions.
Files Included with 4OS2 1.11:
Shareware copies of 4OS2 come with two manuals: the 4DOS manual
(4DOS.DOC, with ASCTAB.TXT) which also documents most 4OS2 commands
and features, and the 4OS2 manual (4OS2.DOC) which describes
differences between 4OS2 and 4DOS, and features unique to 4OS2. We
divide the manuals this way because the great majority of 4OS2 users
also use 4DOS, and the substantial overlap of content would make it
cumbersome to have complete, separate manuals for each product.
The way your copy of 4OS2 is "packaged" will vary depending on the
distribution method (5.25" disk, 3.5" disk, or on-line). In general
there will be one 5.25", 1.2 MB disk, or one 3.5" 1.44 MB disk. On-
line copies will be in two .ZIP files: one -- usually 4DOS4D.ZIP,
4DOS401D.ZIP, or a similar name -- containing 4DOS.DOC and
ASCTAB.TXT, and one -- usually 4OS211.ZIP or a similar name --
containing all other files (including 4OS2.DOC). When possible, the
file names change to reflect the current version number of each
product. If you have an on-line copy and have only one .ZIP file,
check to be sure you are not missing the 4DOS manual or other files
before installing 4OS2.
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 problem (for example, some BBS sysops "brand" 4OS2 with their BBS
4OS2 1.11 [03-08-93] README.DOC page 2
name using software from us; 4OS2 ZIP files on these BBSes will not
show the JP Software verification message). However it does alert
you to the fact that the file has been changed since it was created
by JP Software.
The following files are included with this version of 4OS2:
4OS2.EXE* 4OS2 program file
4OS2.DOC 4OS2 ASCII manual
4OS2.INF 4OS2 help text for use with OS/2's VIEW.EXE
4OS2A.ICO* A sample 4OS2 icon (see page 5 for more
information)
4OS2B.ICO* Another sample 4OS2 icon
4OS2H.MSG 4OS2 quick-help text (for "/?" help)
LICENSE.DOC The 4OS2 shareware license agreement
ORDER.FRM 4OS2 shareware and upgrade order forms
ORDERINF.DOC Ordering and product information
README.DOC This file
SHRALIAS.EXE* Utility program for retention of global alias
and history lists
SUPPORT.BBS Information on Channel 1, the independent BBS
used for 4OS2 support
SYSOP.DOC 4OS2 information for BBS sysops
VENDOR.DOC 4OS2 information for shareware disk vendors
4DOSA.ICO A sample 4DOS icon for use under OS/2 (see
page 5 for more information)
4DOSB.ICO Another sample 4DOS icon
* Files marked with an asterisk differ between the 16-bit and
32-bit versions of 4OS2. If you have a diskette copy, for each
file marked above there are two files on the shareware disk,
and the appropriate file is extracted and renamed during the
installation process. If you have a downloaded copy, your copy
will contain either the 16-bit or 32-bit files, but not both;
in this case no renaming is necessary.
Installing a Downloaded Copy of 4OS2:
(These instructions do not cover diskette installation, because when
4OS2 is installed from diskette this file is not visible until after
installation is complete.)
Whether or not you presently have 4OS2 or 4DOS installed, create a
new directory for this version of 4OS2 (do not install it in the same
directory as a previous version of 4OS2 or 4DOS). Place all of the
downloaded files into the new directory.
You can print the manual, or any 4OS2 documentation file (including
this one), by copying it to the printer with a command like this:
copy 4os2.doc prn
4OS2 1.11 [03-08-93] README.DOC page 3
The documentation files are formatted at 58 lines or less per page,
and contain form feeds and page footers. Printing them with a
program that formats the pages is not likely to work due to the
formatting already included in each file.
Please note that the 4OS2 manual is about 64 pages long, and the 4DOS
manual is over 360 pages long. If you don't want to print these
files, they can be viewed on-screen with a file viewer such as the
4OS2 LIST command. Much of what's in the manuals is also available
in the 4OS2 HELP system. However the HELP system is organized
primarily for quick reference, and may not be the best way to get an
overview of 4OS2's features or to learn about a topic in depth.
If you do print the 4DOS ASCII manual, ASCTAB.TXT (which comes with
it) contains a complete ASCII table for Appendix B. It is separate
from 4DOS.DOC because many printers can't handle the control codes it
contains. If you wish you can print ASCTAB.TXT on your printer if
possible, and paste it into the manual. However you should be aware
that the control codes in this file may make the printed output
completely unintelligible! As an alternative, there is a complete
ASCII table in the 4OS2 HELP system.
4OS2 comes with both 16-bit and 32-bit versions. Before using your
downloaded copy of 4OS2, be sure you have the correct version for
your system.
CAUTION ==> If you are using OS/2 1.x, or the General Availability
("GA") release of OS/2 2.0 (files dated 3-30-92), you
MUST use the 16-bit files. You can NOT use the 32-bit
files.
If you are using any of the following versions of OS/2 you CAN use
the 32-bit files:
* OS/2 2.0 GA with "Service Pack" (IBM CSD XR06055 or later in
the US, or XRx6055 elsewhere), files dated September 1992 or
later.
* OS/2 version "2.01" or "2.0.1" beta, files dated October 1992
or later.
* OS/2 version 2.1 or later, including beta and pre-release
versions of OS/2 2.1.
If you are using the 16-bit version of 4OS2 and upgrade to the 32-bit
version, be sure to replace all the 16-bit files with their 32-bit
equivalents -- don't use some 16-bit files and other 32-bit files, or
4OS2 may not work properly.
To test drive your copy of 4OS2 see the installation instructions in
Chapter 1 of the manual. To install it completely, follow the manual
4OS2 1.11 [03-08-93] README.DOC page 4
installation instructions in Chapter 1, disregarding the discussion
of extracting files from the diskettes.
BE SURE YOU HAVE A BOOTABLE FLOPPY DISK or a copy of your OS/2
installation disks (as described at the beginning of Chapter 1)
before installing 4OS2 on your system. This is not because 4OS2 is
likely to cause trouble. It's because a mistake in the system
startup files or a power failure or other disturbance during
installation, could prevent your system from booting properly (though
this is less likely under OS/2 than under DOS). While such problems
are rare, any time you modify CONFIG.SYS you should have a bootable
floppy disk handy so you can recover if necessary.
Be sure to read the notes in chapter 1 of the manual about modifying
the BOOKSHELF environment variable to make 4OS2's full cross-
referenced help work properly, and about modifying the DPATH variable
to make the "/?" quick help work properly.
Installing 4OS2 Icons:
We provide several sample icons with 4OS2. The "A" icon files show
the 4OS2 / 4DOS logo and product name on a background that matches
the current folder or desktop color. The "B" files are the same but
include a border (you may want to use these for windowed sessions, so
that the border reminds you the session runs in a window). You can
edit any of these icons with the icon editor which comes with OS/2.
To use any icon file for a particular object visible on your OS/2 2.0
desktop (in this case, for objects which start 4OS2 or 4DOS
sessions), open the Settings notebook for the object, click on the
General tab, and then click the Find button next to the current icon
display. In the Find window click Locate; in the Locate notebook
click the Path tab. Fill in the path to the directory where the
desired icon file is stored (fill in only the directory name, not the
full file name) and click OK. Back in the Find window, click the
Find button. When the window opens showing the item(s) found, click
once on the desired icon, then click the OK button. Finally, close
the Settings notebook.
To display a specific icon when a 4OS2 session is minimized, copy the
icon file to the directory where 4OS2.EXE is stored and name it
4OS2.ICO. This step is separate from and independent of the
instructions above for attaching the icon to a desktop object.
Technical Support:
We support 4OS2 in our own CompuServe area, section 10 of the PC
Vendor B forum (GO JPSOFT or GO PCVENB). If you are not currently a
CompuServe subscriber, consider a special offer CompuServe has made
to JP Software customers: call 1-800-848-8199 (outside the US and
4OS2 1.11 [03-08-93] README.DOC page 5
Canada call 614-457-0802) and ask for operator 178 to receive a free
CompuServe introductory membership, including user ID, password, and
a $15 connect time credit.
Our CompuServe ID for direct access to our technical support
personnel is 75300,1215. Use this ID for technical support issues
only. If you have direct CompuServe access please use the PCVENB
forum (as opposed to Mail) whenever possible. For technical support
on the Internet send mail to 75300.1215@compuserve.com.
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 policy is to return all calls within at most 24
hours (weekends and holidays excepted).
Bulletin Board Support for 4OS2:
4OS2 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 4OS2 BBS
support. Phone 617-354-8873 to access Channel 1 at 2400 baud; other
phone numbers are available once you sign up. To download 4OS2 files
join conference 5 and then download the file you need. The file name
for the latest version of 4OS2 is 4OS2xx.ZIP, where "xx" is the
version (e.g. 4OS210.ZIP for version 1.0). On Channel 1 you will be
able to download 4OS2 files even if they appear to be too large for
your remaining time on the system.
If you have access to a local bulletin board which is a member of any
of the major BBS networks (RIME / PC Relay, InterLink, SmartNet, or
FidoNet), you can obtain support for 4OS2 by leaving messages in the
network's 4DOS conference.
4OS2 is distributed directly to some bulletin boards by JP Software,
and uploaded to many more. It is impossible for us to list the
enormous number of boards worldwide that have the latest version of
4OS2, but we encourage you to check your favorite BBS, or use Channel
1. If you are a BBS sysop, see SYSOP.DOC for information on
obtaining a copy of 4OS2 for your BBS.

Using 4OS2 with Other Software
------------------------------
4OS2 is compatible with virtually all OS/2 software, including OS/2
versions 1.2, 1,21. 1.3, 1.3.1, 2.0, 2.01, and 2.1.
Some products which allow access to the 4OS2 command line from within
the product may require a KEYS OFF command to enable line input mode
before command line access will work properly. The only product we are
currently aware of which requires this change is Epsilon from Lugaru
Software.
4OS2 1.11 [03-08-93] README.DOC page 7
Changes in 4OS2 Version 1.11
----------------------------
This list shows all significant changes in 4OS2 since version 1.0.
If you are a new 4OS2 user, you can ignore this list.
If you are currently using 4OS2 1.0, all of the items listed below will
change when you switch to version 1.11. If you are currently using
4OS2/32 version 1.1, only the items marked with asterisks will change;
the other items are already in your current copy of 4OS2. If you are
unsure of what version of 4OS2 you are using, use the VER command to
display your version number.
For more details on any change, see the corresponding command or feature
in the online help or in the manual.
General changes:
* The maximum command line length has been increased to 1023
characters.
There is a new directive in 4OS2.INI: AmPm = Yes | NO | Auto. This
controls the time display format (e.g. in DIR and SELECT output).
Variables and Variable Functions:
* Variable functions that return long integer values (such as @FILESIZE
or @DISKFREE) can now return comma delimited values if you append a
'c' to the size field (b|B|k|K|m|M), e.g. "%@DISKFREE[d:,bc]". Note
that values with commas will NOT be treated as numeric values when
doing IF comparisons.
* @EVAL: Changed to recognize the non-US thousands separator and
decimal characters.
* @REMOVABLE[d]: New internal function returns 1 if the media on that
drive is removable.
Command Changes:
* ATTRIB supports the "attrib file -r" syntax used in some IBM .CMD
files.
DEL supports the /F option to avoid copying files to the DELDIR
directory (4OS2/32 only).
* DEL now displays space freed by deletions whenever possible.
4OS2 1.11 [03-08-93] README.DOC page 8
DIR supports the new /T:[acw] switch to specify the use of last
access, creation, or last write time in directory displays and sorts
on HPFS drives.
* DIR display has been sped up from 15 - 35%.
KEYS OFF has been changed to switch from character to line input mode
for better emulation of CMD.EXE and to improve compatibility with a
few application programs. KEYS ON will switch back to character
input mode. (This is equivalent to the SETDOS /L switch in 4DOS.)
MEMORY displays several additional memory statistics.
START allows specification of DOS settings when starting DOS
sessions. This allows you to set specific DOS session settings
without creating an object on your desktop for the session.
WINDOW is a new command which allows you to change the 4OS2 window
size / state from the prompt or from a batch file.
Bug Fixes and Compatibility Changes:
* REXX subcommand handler name changed to "CMD" for better
compatibility (allows ADDRESS CMD to work).
* The filename passed to an EXTPROC processor will always have a .CMD
extension (some EXTPROC processors expect this). Previously the name
was passed as you typed it, with or without the extension.
* The command name passed to external programs will now reflect the
name as you typed it, without any path information added (some
programs could not handle the added path information).
* Fixed some minor reliability problems with multiple secondary 4OS2
shells.
* Fixed a problem with running external programs from HPFS drives when
the path or file name contained "=" or "+".
* Fixed interaction problems with IBM's INSTAID utility.
* Changed 4OS2's redirection operators to avoid reducing the number of
file handles initially available to external programs.
* BORDER colors are now disabled in all commands except CLS and COLOR
(they were never documented to work except in CLS and COLOR).
* COPY: Fixed a bug which could cause /C and /U to compare file dates
and times incorrectly; changed to allow "+" characters inside quoted
filenames (COPY was treating these as a request to append files).
4OS2 1.11 [03-08-93] README.DOC page 9
* DETACH: Changed (for compatibility with CMD.EXE) to pass everything
following "DETACH" to the detached process, including pipes, command
separators, conditional commands, redirection, etc.).
* DIR: Worked around an OS/2 bug which resulted in doubling of
displayed EA sizes on HPFS volumes in 4OS2/32 1.1; fixed a problem
with extremely large HPFS directories (2000+ files).
* EXIT: Will no longer cause an infinite loop when used inside 4EXIT.
* LIST: Fixed a problem with /W truncating lines in binary files.
* MOVE: Fixed a bug which could cause /C and /U to compare file dates
and times incorrectly. Also, changed MOVE /S to give an error on
attempts to perform infinitely recursive moves (e.g. MOVE /S
\DIR1\*.* \DIR1\SUBDIR\).
* SELECT: Worked around an OS/2 bug which resulted in doubling of
displayed EA sizes on HPFS volumes in 4OS2/32 1.1.
