12. CLOSING WORD1. INTRODUCTION TO LEGROOM
-----------------------
LegRoom Ver. 2.0 is a TSR maker and task swapper for DOS-based
personal computers.
LegRoom is published by Ivden Technologies, Inc. as part of its
line of memory resident utilities. LegRoom was designed to solve
two problems:
a) shelling to DOS from programs that don't have a DOS shell
function
b) shelling from programs whose shell function gives too little
memory at the DOS prompt to do any useful work.
LegRoom allows you to Shell to DOS from any text and most
graphic applications. It loads as a TSR (Terminate and Stay
Resident) program and is triggered when you press a hot key.
Version 2.0 now lets you make any program (even a DOS batch file)
pop up as a TSR when you press the hot key.
LegRoom will run under DOS 2.0 and up.2. SHAREWARE CONCEPT
-----------------
"Shareware" is a term used to describe a system for distribution of
software. Under the shareware concept, software may be freely
copied and passed along to others, or distributed through bulletin
board systems, shareware distribution companies, etc.
As a recipient of a shareware program, you may use the software for
a short trial period to determine if it meets your needs. If it
does, you pay the registration fee. By paying the fee, you are
granted the right to retain the software for your use. If the
software is not suitable, then you may discard it.
The shareware system provides substantial benefits to the computing
community (of which YOU are a member):
a) You get to try out the software BEFORE you buy it so you know
exactly what you're buying.
b) Shareware is substantially less expensive than most commercial
programs. You don't pay for costly marketing programs and
fancy packaging.
c) You get access to a MUCH broader base of available programs.
Thousands of excellent programs have been written by expert
programmers who would never consider marketing commercially.
Through the concept of shareware, these people make their
programs available to the community. Usually, all they ask in
return is a small fee to reward them for the time and effort
they've put into the program.
The system is based entirely on the honor system, and generally
works quite well. (Most people are honest and wouldn't violate the
trust placed in them by the author of the software.)
Shareware is NOT free software - the author counts on your
integrity. See Why and How to Become a Registered User.
You are encouraged to copy this software and pass it along to
others who may be interested in using it.3. ACKNOWLEDGMENTS

5. INSTALLATION
------------
Install the program by following these steps:
a) Copy the file LGROOM20.ZIP to the directory of your choice
b) Extract the compressed contents by using the shareware
decompression program PKUNZIP. If you don't have a copy,
you can probably get one where you obtained LegRoom. You can
download it from most BBSs and info services, e.g., CompuServe.6. HOW TO USE LEGROOM
------------------
LegRoom runs on any IBM compatible computer running MS-DOS,
Version 2.0 and up, or 100% compatible operating system.
Load LegRoom by entering the command LEGROOM from the directory
where you installed it. You can also add that command to your
AUTOEXEC.BAT file to load LEGROOM whenever you boot your computer.
That way, it will stay in memory for use whenever you need it.
LegRoom auto-detects the presence of extended and expanded
memory and takes advantage of them. If available, it loads itself
into expanded memory, taking up less than 2 KB of conventional memory.
When you press the hot key, the current application is suspended.
It is moved to a holding area in extended memory, expanded memory,
or your hard disk, depending on which is available.
The program, its data, video memory, mouse state, floating point
coprocessor state, etc. are saved, as are your current drive and
directory.
When you are finished running other programs, type EXIT to return to
the suspended application. Its state is restored to that saved prior
to pressing the hot key.
You needn't have an expanded memory board to have expanded memory.
Memory managers such as EMM386, QEMM386, and 386MAX emulate
expanded memory for applications which call for it.
There are six command line parameters you can use to control the
behavior of LegRoom. These parameters are described below:
LEGROOM [/D | /N] [/H=n] [/R=p] [/U] [/?],
where:
/D creates a temporary disk file for holding the current
application, instead of using extended or expanded memory
/N uses extended memory, if available, for holding the
current application, but DOES NOT use expanded memory
(this makes it run compatibly with QEMM in 'stealth' mode
and the NetWare driver EMSNET)
/H=n changes the default hot key from Ctrl-Shift-0 to
Ctrl-Shift-n, where n is between 0 and 9
/R=p causes any program or DOS batch file to be run when the
hot key is pressed (p is the complete path and file
specification (including .exe, .com, or .bat extension)
and optional command line
/U unloads LegRoom from memory (you cannot unload it when
you have shelled to DOS using it)
/? displays help information without loading LegRoom.
To trigger LegRoom, press the default hot key or the hot key
you requested if you used the /H=n parameter as described above.
Use the standard number keys on your keyboard, NOT THE NUMERIC
KEYPAD.7. USAGE NOTES
-----------
You can load LegRoom into upper memory with the "load high"
facilities of a memory manager. This saves a small amount of
conventional memory. The amount of the savings is greater when using
the /N or /D switch. These switches prevent a 386 based memory
manager from loading most of LegRoom into expanded memory.
Ctrl-Break is disabled at the new DOS prompt after triggering
LegRoom. Use Ctrl-C instead of Ctrl-Break to break out of a
process launched from the new DOS prompt.
DON'T SHELL FROM A SHELL! If you loaded LegRoom without the /R=
switch, you cannot trigger LegRoom when at the DOS prompt. This
would be a waste of memory or disk space. However, LegRoom does
not detect the presence of a DOS prompt created by using a program's
built-in shell feature. Use one or the other, but not both.
You can use LegRoom from multitasking environments such as
DesqView and Microsoft Windows. The advantages of LegRoom are
greatest in a single tasking DOS environment. If you decide to use
LegRoom in a multitasking environment, be sure to load it from within
a DOS 'box' or DOS 'window', NOT before entering the environment!
Do not use LegRoom to shell from a communication program while
transferring data. Shelling with LegRoom suspends the current
application. It does NOT keep running in the background. Data will
be lost if you use LegRoom to shell to DOS while performing a
file transfer.
You should, in general, not load a TSR into memory when you have
shelled to DOS from an application. When you exit the application,
your conventional memory pool has a 'hole' where the application was.
This is called fragmentation. It reduces the largest block of memory
available to programs.
If you use LegRoom to make a batch file act as a TSR, add the
following line to the end of the batch file: EXIT
If it is necessary for LegRoom to create a swap file, it is
identified by the LR_SWAP environment variable. It is recommended
that you set this variable in your AUTOEXEC.BAT file so that it is set
automatically whenever you boot your computer. Otherwise, the swap
file is stored in a subdirectory named 'TEMP' under the directory
where you installed LegRoom.
The swap file is stored with System and Read-Only attributes to reduce
the risk of deletion or renaming while LegRoom is loaded.
LegRoom supports any number of concurrent users on a network.
Each user should be assigned a unique swap file in his/her LR_SWAP
environment variable to avoid 'collisions'. Similarly, if you use
LegRoom in multiple DOS sessions in DesqView or Microsoft Windows,
and expect it to use disk space for swapping, set LR_SWAP to a
different directory in each session before loading LegRoom.
Each time LegRoom is loaded, the old swap file (if any) is replaced by
a new one. The old swap file is also removed on unloading LegRoom.
Rebooting or turning off the computer without first unloading
LegRoom results in the current swap file remaining on the disk.
LegRoom supports all standard graphic adapters and modes as well
as Super VGA modes up to a maximum video memory requirement of 256 KB.8. DISCLAIMER

--------------------------------------------------
A hypertext Readme document is also provided with this package.
It was created using another Ivden product, DeskTop Advisor(R),
a hypertext document authoring system.
In DeskTop Advisor, information is organized in topics. From any
topic, you can select other topics to explore by pressing Alt-T.
To browse the DeskTop Advisor documentation, change to the directory
on the disk where you installed LegRoom. Then enter the command:
DA_BROWS LROOM
from the DOS prompt. The system will guide you from there. It is
menu-driven and does not require a mouse.
Every time you visit a new topic, a bookmark is placed at the current
topic. No matter how deeply you go into the guide, you can retrace
your steps, one topic at a time by pressing Ctrl-PgUp or pressing
Alt-T and selecting ** PREVIOUS TOPIC **. To return to the beginning
of this document from any topic, press Ctrl-Home or press Alt-T and
select ** INTRODUCTION **.
The Master Topic Index
----------------------
You are not limited to using Alt-T for topic selection. You can
access any topic wherever you are in the document.
From any topic, you can view the master index of topics by pressing
the Space Bar. Next, using the PgUp, PgDn, arrow keys, and keys
for the first letter of a topic, you can highlight a topic of
interest. Then, press Enter to proceed to the selected topic.
As always, you can return to the previously visited topic by pressing
Ctrl-PgUp or pressing Alt-T and selecting ** PREVIOUS TOPIC **.
Hyperlinks
----------
On any screen there may be key words (called 'hyperlinks') about which
you would like to get more information. By pressing the Tab key, you
will make all such words appear highlighted. The first hyperlink on
the screen is blinking, indicating it is currently selected.
You can highlight a hyperlink in which you are interested by using
the Tab, Home, and End keys. Press Enter and a menu of topics
which reference the hyperlinked word appears. Select a topic which
seems to be relevant to your needs. That topic will pop up in a
window. Use the up and down arrow keys to view each page on which the
word is used.
When finished viewing the selected topic, return to the underlying
topic by pressing Ctrl-PgUp. Select another related topic to
explore or press ESCape to return to the underlying screen.
Keyword Search
--------------
You can perform a query from any topic to find all topics which
relate to keywords of interest to you. Press Alt-F, then Q to
select Query from the Files menu. As a shortcut, just press F2.
Now enter up to three keywords which describe an area of interest
to you. All topics which reference all the keywords will be
retrieved, including the current topic. Each additional keyword
beyond the first serves to narrow the search, filtering out more
irrelevant topics.
A menu of topics which satisfy your query will be presented.
Select a topic and browse it using the PgUp and PgDn keys.
When finished viewing the selected topic, return to the underlying
topic by pressing Ctrl-PgUp. Select another related topic to
explore or press ESCape to return to the underlying screen.
Self-Promotion
--------------
DeskTop Advisor has a few other features, not included here, such
as graphic images and sound overlays. Sound Support(tm), a recorded
voice supplement to the standard help screens, is also included with
the product. In addition, a DeskTop Advisor document can be made
memory resident, to be triggered by a hot key as needed.12. CLOSING WORD
------------
That's all there is to it! We know LegRoom is so easy to use it
doesn't really need hypertext documentation. But, we want as many
computer users as possible to be exposed to the concept. We hope to make
DeskTop Advisor a standard tool for publishing on-line documentation
for software. Thanks for trying it. Your feedback is requested.
Of course, we hope you find that LegRoom makes your DOS environment
more productive. If you like the product, please register it. If you
have comments -- positive or negative -- please share them with us.
