Appendix A DesqView

 The Setup program that runs after you install DESQview can be run again, any
time. You may run it within DESQview (if you have added it to your Open
Window menu using Add a Program) or you may run it outside DESQview, from
DOS. When you run it from inside DESQview, changes will not take effect until
the next time you start up DESQview.

When you install DESQview on your system, certain assumptions are made about
how your system is configured and about how you would like DESQview's options
set. You can change these default assumptions by running the Setup program.

Assuming the you've installed DESQview in the DV directory of drive C on your
hard disk

~Begin footnote~

If you're running on a floppy-based system rather than on a hard disk system,
follow these steps instead: Place your everyday DESQview diskette in drive A.
Type A: and press <Enter>   to set the default drive to A. Type  SETUP and
press <Enter>.

~End footnote~

~Step~ Type C: and press <Enter> to change the default drive to C.

~Step~ Type CD\DV and press <Enter> to change the default directory to DV.

~Step~ Type SETUP and press <Enter>.

This loads the Setup program, which takes a moment. Then the DESQview
copyright notice appears for a moment and the main DESQview Setup menu
appears. You can choose the simple setup procedure or the advanced one:

~Item~ Space bar selects the simple setup procedure, designed for the
first-time user. It asks you only a few basic questions about your monitor
and your use of a mouse. All other DESQview options are given default values.

~Item~ <Enter> selects the advanced setup procedure, designed for the
experienced user. It lets you configure all of DESQview's options.

~Step~ Press the space bar or <Enter>.

 When you type SETUP, you actually invoke a batch file that starts up
DESQview in a special mode. In this special mode, the DESQ key is disabled,
and DESQview automatically closes down when you finish the Setup program.

~Heading~ Setup for the First-Time User

 The main DESQview Setup menu gives you the choice of using either the simple
setup procedure, for the first-time user, or the advanced setup procedure,
for the experienced user.  If you choose the simple procedure, you need
answer only a few basic questions:

~Item~ What type of monitor and display adapter board do you have?

~Item~ Have you installed a mouse and, if so, what type of mouse?

Additionally, in the event that your system has exTENDed memory installed and
no XMS memory manager is installed, Simple Setup will ask you if you wish to
install QEXT.SYS, which is provided on your DESQview diskette and copied to
the diskette or directory on which you installed DESQview. If you are
currently using HIMEM.SYS, you should remove it and let QEXT.SYS supply these
services instead.

A file called DVXMS.DVR is also supplied with DESQview.  This is a driver
which DESQview will automatically load when it starts up if you are using an
XMS driver (i.e.; QEXT, HIMEM or QEMM-386 Version 5 or higher).   DVXMS.DVR
allows DESQview to arbitrate the use of XMS so that:

~Item~ If you use DESQview's Close Window command to shut down a program
which is using XMS memory, DESQview will release those XMS resources.

~Item~ You can limit the amount of XMS memory that a program can access by
setting the desired value in the "Maximum Expanded Memory Size (in K)" field
on the Change a Program Menu (second screen).

~Item~ Multiple windows running Lotus 1-2-3 Rel 3 can be open in DESQview on
an 80286 PC with this XMS support.Otherwise, you would only be able to open
one 1-2-3 Rel 3 window.

~Subhead~ Simple Setup: Monitor

 The simple setup procedure examines your system's hardware configuration to
see what type of display adapter board is installed:

~Item~ If a monochrome board or a Hercules board (or compatible) is
installed, no monitor question is asked.

~Item~ If a Color Graphics adapter (CGA) board, and Enhanced Graphics adapter
(EGA) board, or a Video Graphics Array (VGA) board is installed, you're
asked:

 ~dash~  Whether you get snow on your screen.  This determines if your
display hardware requires synchronization.

 ~dash~  Whether you want DESQview to use color.  Sometimes a monochrome
monitor is attached to a "color" adapter board, giving gray scale instead of
true color. In this configuration, you'll usually want to turn off "color."
For example, most portable and laptop PCs have this configuration.

~Subhead~ Simple Setup: Mouse

 Next, the simple setup procedure examines your system to see if any of the
mouse drivers it knows about have been loaded:

~Item~ If a known mouse driver is loaded, you're asked if you want to use
this driver.

~Item~ If no mouse driver is loaded, you're asked if you have a mouse
installed on your system. If you do, you're asked to specify:

 ~dash~  The brand of mouse you're using: PC Mouse (Mouse Systems), Microsoft
Mouse, Logimouse, VisiOn Mouse, Maynard Mouse, or AT&T Mouse.

 ~dash~  How the mouse is attached: as an add-on board or to communications
port 1 or 2.

Finally, as noted on the previous page, if DESQview detects ExPANDed memory,
but no XMS driver, you'll be asked if you want to use one.

That's all. Now, the next time you start up DESQview, the choices you just
made will be in effect.

 Normally, the Setup program is run automatically when you install DESQview.
However, should you install DESQview without running the Setup program.
DESQview will assume that you have no mouse and, if you have a CGA, EGA, or
VGA board, that it requires synchronization and displays multiple colors.

~Heading~ Setup for Advanced User

 If you choose advanced setup, the following window appears:

This window lists the complete set of DESQview options that you can configure
using the Setup program. The following sections of this appendix explain each
of these options in detail. To select an option:

~Step~ Type the letter of the option you want.

When you've changed all the options to the values you want:

~Step~ Press <Enter>.

The following window appears:

To store the changes you've made:

~Step~ Press <Enter>.

The Setup program is closed down. Now, to put the changes you made to
DESQview's options into effect:

~Step~ Start up DESQview.

~Heading~ Advanced Option: Auto Dialer

 The Auto Dialer option lets you specify:

~Item~ What port your modem is attached to.

~Item~ What baud rate you want to dial at.

~Item~ What names and access codes you want to appear on the Dial menu.

~Item~ What dialer protocol you're using.

~Subhead~ What Port?

 Your modem can be attached to communications port 1, 2, 3 or 4.

~Subhead~ What Baud Rate?

 Available baud rates are 300, 600, 1200, 2400, 4800, and 9600. If you'll be
using the Auto Dialer while running a communications program, select Leave As
Is to prevent the Auto Dialer from resetting your communications port.

~Subhead~ What Access Codes?

 The Dial Menu (see page 69) initially appears as:

Each access code is set to dial "1". You can replace the string, "Access Code
n" with any text you choose ~dash~ for example, Sprint, MCI, AT&T. You can
replace the default access code "1" by any access code up to 25 digits long.
You can embed any characters that your modem understands in this access code.
(See page 69 for the characters that a Hayes modem understands.)

 To force your communications port to set to a particular rate when a number
is dialed, enter "^1" through "^6" as the first two characters of Phone
Number & Code, where ^1 corresponds to 300 Baud, ^2 to 600 Baud, ^3 to 1200
Baud, ^4 to 2400 Baud, ^5 to 4800 Baud, and ^6 to 9600 Baud.

~Subhead~ What Protocol?

 The Auto Dialer is initially configured to use Hayes Smartmodem protocol.
If your modem isn't fully Hayes-compatible, you can change the protocol by
changing Prefix to specify the commands to send before the number, Postfix to
specify the commands to send after the number, and Hangup to specify the
command to hang up the modem. Setup recognizes ^X as meaning Ctrl-X.

 It's not possible to reconfigure all modems to work with DESQview's Auto
Dialer feature using this method.  If there are no values that work for your
modem in these three fields, you can't use that modem with the Auto Dialer.

~Heading~ Advanced Option: Colors

 The Colors option lets you control:

~Item~ Whether you want DESQview to use color.

~Item~ What colors you want DESQview to use for programs that aren't written
for color and what colors you want DESQview to use for DESQview menus (if
you're using color).

~Item~ What colors you want DESQview to use for programs written expressly
for DESQview (if you're using color).

 The Colors option isn't selectable if you're using a monochrome monitor.

~Subhead~ Use Color?

 A Color Graphics adapter (CGA) board, despite its name, may be connected to
a monochrome monitor. When you do this, gray scale is displayed instead of
true color. In this configuration, you'll usually want to turn off "color."
For example, most portable and laptop PCs have this configuration.

~Subhead~ What Window Colors?

 If you elect to use color, you can define five color schemes:

~Item~ Four Window color schemes.

~Item~ A color scheme for DESQview menus.

When you open a window, DESQview displays the window in one of its four
window color schemes ~dash~ in round-robin fashion. Windows 1, 5, 9, and so
forth receive the first color scheme. Windows 2, 6, 10, and so forth receive
the second color scheme, and so on. When you display a DESQview menu, it's
displayed in the DESQview menu color scheme. Color schemes selected in Setup
will be the default colors.  They can be overridden by specifying that a
program use its own colors (Change a Program menu) or by using DESQview
Pallette (see page 57).

Each color scheme consists of a text color and a background color. Text can
appear in normal intensity or highlighted.

 Whether a window receives a color scheme from DESQview, or uses its own
inherent color scheme, is controlled by the Writes text directly to screen
and Uses its own colors options on the Change a Program menu.

~Subhead~ What Program Colors?

 If you are running in color,  you can select eight color schemes ~dash~ for
"normal text," "emphasized normal text," "error text," and so forth ~dash~
for programs written expressly for DESQview.

~Heading~ Advanced Option: Keyboard

 The Keyboard option lets you specify:

~Item~ Whether you want DESQview's Learn facility to be available.

~Item~ What quoting character you want Learn to use (if you're using Learn).

~Item~ How much memory DESQview should allocate for its various Learn buffers
(if you're using Learn).

~Item~ Whether you want to change the keystrokes used to generate the DESQ
key, the Learn key, and the key used to toggle the "keyboard mouse."

~Subhead~ Use Learn?

 One of DESQview's most powerful features is Learn ~dash~ see Chapter 5,
Learn: DESQview's Keystroke Macro Feature . Normally, you want Learn enabled.
The main exceptions would be when you've already developed a macro library
using another keystroke macro program or you want to save the amount of
memory Learn uses (approximately 9K for the Learn driver and 1K for each
(default length) script buffer.

~Subhead~ What Quoting Character?

 When you create Learn scripts (keystroke macros), you assign each script you
create to a key on the keyboard. The key you reassign (called the mapped key)
no longer performs its original function. When you press it, the script
defined for it is played back. The quoting character lets you override a
key's mapped meaning and perform the key's original action instead.

 The default quoting character is ` If you elect to use Learn, you can
specify a different quoting character. (The character you select must be one
of the 95 standard ASCII characters, 32-126.) Also see page 40.

~Subhead~ What Buffer Sizes?

 DESQview has three global script buffers, plus a script buffer for each
program you run in DESQview. The size of the script buffer for a program is
determined by Script Buffer Size on the Change a Program menu for that
program. The size of each global script buffer is determined by the setting
you make in the Keyboard option:

~Item~ The DESQview Scripts buffer is the area of memory where all scripts
learned on all DESQview menus are stored (see page 90).

~Item~ The Learn Scripts buffer is the area of memory used to record a script
while it's being learned. When the script is complete, it's transferred into
the DESQview Scripts buffer or the Program Scripts buffer. Thus, the Learn
Scripts buffer must be large enough to accommodate the longest script you
ever intend to learn, including nested scripts and embedded learns (see page
90).

~Item~ The Playback Scripts buffer is the area of memory used when you
perform (play back) a script.  DESQview begins by loading the entire script
into this buffer. Then it performs the script.  If the script invokes other
scripts, these other scripts are also loaded into this buffer as needed.
When playback of a script (or nested script) is complete, the buffer space
for that script is released.  Thus, the Playback Scripts buffer must be large
enough to contain the largest script (including all nested scripts and
embedded learns) that you ever intend to play back (see page 8481).

 The size of all script buffers is initially set to 1,024 bytes each. For
more information on the DESQview Scripts, Learn Scripts, and Playback Scripts
buffers, see Chapter 5, Learn: DESQview's Keystroke Macro Feature.

~Subhead~ Maintain Separate Shift States?

 The BIOS data area contains information on the shift states of the computer.
If you enter "Y" here to turn this option ON, DESQview will keep track of the
state of the NUM LOCK, CAPS LOCK, SCROLL LOCK or PAUSE keys for each window.
When running concurrent applications, it may be useful to have the keypad set
in NUM LOCK for some of your applications, while other applications see
cursor movement from the numeric keypad. For example, if NUMLOCK was ON when
you switched away from Lotus 1-2-3, regardless of how you may have used it
when you typed into a WordPerfect window, NUM LOCK would be engaged when you
came back to 1-2-3.

~Subhead~ What System Keys?

 DESQview takes three keys for its own use:

~Item~ The DESQ key (normally, Alt) is the key you press to get DESQview's
attention and display the DESQview menu (see page 36).

~Item~ The Learn key (normally, Shift-Alt) is the key you use to display the
Learn menu, and thereby invoke DESQview's Learn facility (see page 36).

~Item~ The "keyboard mouse" toggle key (normally, Ctrl) is the key you use to
turn the "keyboard mouse" ON or OFF. It's only used if you do not have a real
(hardware) mouse installed on your system (see page 44).

These keys can be redefined. However, we recommend against doing so unless
they conflict with your hardware or with key usage in programs you run under
DESQview.

 An exception might be the "keyboard mouse" toggle key. If you don't want the
"keyboard mouse" capability on your system, you can effectively disable it by
setting "Keyboard Mouse" Key to an impossible or unreasonable setting.

 Note that the use of Alt as the DESQ key does not conflict with the use of
Alt as a shift key ~dash~ for example, as Alt-X. You have a conflict only if
tapping Alt doesn't display the DESQview menu or if you're running a program
that uses Alt alone or (sometimes) in an unusual combination.  For example,
Ctrl-Alt, as used by Sidekick, may cause such a conflict. (In this case,
however, we recommend accessing Sidekick by holding down both shift keys
rather than by redefining the DESQ key.)

 The System Keys settings are highly technical and beyond the scope of this
manual.  Basically, however, you must specify the key to be pressed and
released and the "shift key" that's to be held down at the time you press and
release this key.  For example, the default setting for the Learn key
specifies that the key to be pressed and released is Alt and the "shift key"
is Shift. So, to "tap the Learn key" you hold down the Shift key and then
press and release the Alt key.

~Heading~ Advanced Option: Logical Drives

 The Logical Drives option lets you:

~Item~ Take full advantage of DOS directories, even for programs that don't
understand about directories, by defining up to 16 logical drives.

~Item~ Specify the drive and directory to use when DESQview needs to swap a
program out of memory to free up enough space to run another program, or when
DESQview doesn't have enough memory to save a "graphics screen."

Warning:  Do NOT enter anything in Logical Drives unless you really mean to
assign a logical drive.  Unless you need logical drives, it is best to leave
them blank.

~Subhead~ Drives A-P

 Some older programs don't allow you to enter file names that include a
directory path specifier. On the other hand, virtually all programs allow you
to enter file names that include a drive specifier. For example, the file
name C:\DB-DATA\INVENTRY is not acceptable to dBASE II. However, the name
G:INVENTRY is acceptable.

The Logical Drives option lets you associate a drive letter ~dash~ A through
P ~dash~ with a DOS directory name. DESQview then maps this drive assignment
to the directory path for you. The program continues to think it's addressing
a physical disk drive and thus is satisfied.

Each logical drive field allows room for 20 characters. For each subdirectory
you want reassigned as a drive, enter in the field for that drive the drive
and directory you want referenced when that drive specifier is used by a
program running in DESQview.

IMPORTANT: You must enter both a drive letter and a directory name.  A drive
letter or directory name standing alone is invalid. Also, do not reassign the
drives that physically exist on your system ~dash~ most commonly, A, B, and
C, or any logical drive partitions you may have already set up for a hard
disk.

For example, you might enter C:\DB-DATA in the field for drive G. Now, when
you use the file G:INVENTRY in dBASE II, DESQview will remap it so that dBASE
II accesses the file C:\DB-DATA\INVENTRY.

~Subhead~ SWAP Drive

 The SWAP drive has a special use in DESQview:

~Item~ It specifies the drive and directory to which DESQview should swap out
programs when it needs memory to start up another program ~dash~ or when you
explicitly tell DESQview to swap out a program using the Put Aside command.

~Item~ It specifies the drive and directory to which DESQview should save
"graphics screens" when there's not enough memory available to save them in
memory.

 We refer to the information that a program writes to the standard (25x80,
30x80, and so forth) area of your video display as a "screen."  When you
switch away from a program, its "screen" is saved so that it can be restored
when you switch back.  Text screens are always saved in memory. "Graphics
screens", however, are often too large to save in memory ~dash~ up to 256K in
certain EGA and VGA modes.  So, "graphics screens" are normally saved in
expanded memory or on disk (see pages 124-125).

The correct value to enter in the SWAP drive field depends on your hardware
configuration:

~Item~ Expanded Memory. If you have a PC, PC-XT, PC-AT, or Personal System/2
with an expanded memory (EMS3.2 or EMS4) board or an enhanced expanded memory
(EEMS) board installed on your system, leave the SWAP drive field empty.
This tells DESQview to swap out to EMS or EEMS memory ~dash~ a very
high-speed, almost instantaneous, operation.

~Item~ 386 PC. If you have a Personal System/2 Model 80 , 386  or i486 PC,
and have loaded Quarterdeck Expanded Memory Manager 386 (QEMM-386), leave the
SWAP drive field empty. This tells DESQview to swap to 386 extended memory
(above 1MB) ~dash~ an almost instantaneous operation.

~Item~ No expanded Memory:

 ~dash~  PC or PC-XT.  If you have a PC or PC-XT without extra memory (above
640K) for a RAM disk, you can either enter a drive and directory in the SWAP
field or leave it empty. If you enter a drive and directory, DESQview
performs all swapping to where you specify.  If you leave the SWAP drive
empty, DESQview will swap to the drive and directory from which you started
up DESQview (most commonly, C:\DV).

 ~dash~  PC-AT. If you have a PC-AT with extended memory above 1MB but with
no EMS or EEMS memory, we recommend that you allocate part of the memory
above 1MB to a RAM disk (using VDISK or an equivalent driver) and then enter
the letter of that RAM disk in the SWAP drive field. Swapping to RAM disk is
nearly as fast as swapping to EMS or EEMS memory.

 ~dash~  386 PC.  If you have a 386 or i486 PC with no EMS driver, we
recommend

~Begin footnote~

We also recommend that you see the notes on installing DESQview at the end of
Chapter 1 (or consult your dealer or Quarterdeck) for information on why you
should consider getting Quarterdeck Expanded Memory Manager 386 (QEMM-386) to
take full advantage of the power of your 386 PC, if you don't already have
it.

~End footnote~

 that you allocate part of you 386 extended memory (above 1MB) to a RAM disk
(using VDISK or an equivalent driver) and then enter the letter of that RAM
disk in the SWAP field. Swapping to RAM disk is nearly as fast as swapping to
extended memory using an EMS driver.

 When you assign the SWAP drive to a RAM disk or expanded memory, DESQview
automatically reverts to swapping to your hard disk if you run out of RAM
disk space or expanded memory space ~dash~ storing programs on the drive and
directory from which you started up DESQview (most commonly,C:\DV).

~Heading~ Advanced Option: Mouse

 The Mouse option lets you specify:

~Item~ What brand of mouse, if any, you've installed on your system.

~Item~ How the mouse hardware is attached to your system.

~Item~ Whether you want to use the mouse right-handed or left-handed.

~Subhead~ What brand?

 If you don't have a mouse installed on your system, select the Keyboard
option. This gives you access to the "keyboard mouse" (see page 44), which
lets you emulate a hardware mouse using the keyboard.

If you do have a mouse installed on your system, indicate which brand you
have: PC Mouse (by Mouse Systems), Microsoft, Logitech, Visi On, Maynard
Mouse, or AT&T Mouse.

If you don't have a Microsoft mouse, but have installed your mouse with a
Microsoft mouse driver, you should select Microsoft ~dash~  not the actual
brand of the mouse.

 When you use a three-button mouse with the Microsoft mouse driver, the
description on page 42 (and in Chapter 2, Getting Started: A Tutorial)
doesn't apply. The left-most button is the select button (BUTTON 1) and the
right-most button is the cancel button (BUTTON 2). The middle button is
unused.

~Subhead~ How Attached?

 Specify whether the mouse is attached as an add-on board (bus mouse) or to
communications port 1 or 2.

~Subhead~ Left-Handed?

 If you select a left-handed mouse, the positions of the mouse buttons are
reversed. BUTTON 1 becomes the right-most button. BUTTON 2 becomes the
left-most button. If you have a three button mouse, the middle button remains
the DESQ button. See the picture on page 42.

 You can't reverse the "keyboard mouse" buttons (see page 44).

~Heading~ Advanced Option: Performance

 The Performance option lets you customize the performance characteristics of
DESQview to you personal needs. You can specify:

~Item~ How DESQview allocates time to foreground and background programs.

~Item~ The amount of "common" DESQview memory to allocate and, if you have
expanded memory, the size of the EMS DOS buffer to use.

~Item~ Whether DESQview should optimize communications programs.

~Item~ Whether DESQview should ever swap programs out of memory to free up
space to run other programs.

~Item~ Whether DESQview should manage printer contention.

~Subhead~ What Processing Time?

 You can control the number of clock ticks that DESQview gives to the
foreground program and to each background program. (The clock ticks 18 times
a second.) In general, you should give each program a minimum of 3 ticks
~dash~ 2 on a 386 PC. With anything less, the program may have too little
time to do any work.

DESQview allocates time to each program in round-robin fashion. First, the
foreground program is given the number of foreground ticks indicated. Then,
each background program is given, in turn, the number of background ticks
indicated. If a program is waiting for keyboard input, and none is waiting,
DESQview skips this program.

The correct settings for these tick counts depend on what you do in
foreground and in background. If you work mostly in foreground, and only
occasionally run programs concurrently in background, the default setting of
9 foreground ticks and 3 background ticks is probably correct. If you do
light work in foreground ~dash~ word processing, enter information in data
base records, constructing spreadsheets (with few recalculations or automatic
recalculation turned off) ~dash~ and heavy background processing ~dash~
sorting databases, downloading from mainframes, recalculating large
spreadsheets, checking long documents for spelling errors, and so forth
~dash~ you may want to change these settings to increase the time allocated
to the background.

 The way to determine the optimum settings is by trial and error. In addition
to allocating default clock ticks here in the Setup program you can also
dynamically set these values from the DESQview Tune Performance menu. Change
the settings to the new values you think are appropriate and run the
combination of programs you're working with. Don't give extreme values to
either count. For example, if you set foreground to 3 ticks and background to
50 ticks, the foreground program will virtually grind to a halt. Also, with
too high a setting for the foreground program, some background tasks could
concievably "time out."

~Subhead~ What Memory Usage?

 When you start up DESQview, it allocates space for "common" DESQview memory,
for an EMS DOS file buffer (if required), and for the script buffers
described in the What Buffer Sizes? section on page 139124:

~Item~ Common Memory (initially, 17K) is the area of memory DESQview uses:

 ~dash~  To store the information DESQview needs to manage windows.

 ~dash~  To store the Open Window menu (the contents of the file,
DESQVIEW.DVO ~dash~ see Appendix G).

 ~dash~  To store the information marked with the Mark command.

 17K is sufficient for DESQview to keep track of about seven windows and
still have room for a full (25x80) screen's worth of Mark information.  If
you get the message Not enough common memory when trying to open a window,
increase the Common Memory area size.

~Item~ DOS Buffer for EMS (initially, 2K) is meaningful only if you have
expanded (EMS or EEMS) memory or are running on a 386 PC and have loaded
QEMM-386 ~dash~ see page 141, SWAP Drive   in this appendix  for more about
this. This buffer is used to manage file operations into expanded memory and
may affect the performance of your system. If programs storing data in EMS
memory, or running in EEMS memory, seem to be slow at performing DOS file
operations, increase the DOS buffer size. There is little value in increasing
the size above 30K.

~Subhead~ Optimize Communications?

 If you're running communications programs in DESQview, you normally want
DESQview to optimize its handling of these programs. However, DESQview's
optimization technique may cause a few PC-compatibles to hang (freeze). If
DESQview hangs at startup, turn this option OFF. This may reduce your ability
to run communications at very high speed ~dash~ 4800 or 9600 baud.

~Subhead~ Allow Swapping?

 When DESQview needs more memory than is available to run a program, it frees
up memory by swapping out a background program. Normally, this is a desirable
feature (see Put Aside on page 53 and SWAP Drive on page 141). Sometimes,
however, you may want to completely disable this feature ~dash~ most commonly
on floppy-based systems without expanded memory. To disable, enter "N" in
this field.

~Subhead~ Manage Printer Contention?

 One of the most common uses of background processing is printing.  If you
have several programs which simultaneously want to print in background or in
foreground), you normally manage this yourself by not starting to print in
one program until the other one is finished. If you want, you can tell
DESQview to manage this problem for you. When you do, DESQview suspends any
program that tries to use the printer if another program is already printing.
If DESQview manages printer contention, it will send a form feed at the
beginning of each print job.

~Heading~ Advanced Option: Video Monitor

 The Video Monitor option lets you specify:

~Item~ What type of display adapter board is installed on your system.

~Item~ Whether you want DESQview to allow text and graphics to be displayed
on the screen at the same time.

~Item~ Whether your display hardware requires synchronization.

~Item~ Whether you want DESQview to blank the screen after a certain time.

~Subhead~ What Display Adapter?

 Indicate the type of display adapter board installed on your system:
Monochrome, Color Graphics (CGA), Hercules (or compatible), Enhanced Graphics
(EGA/VGA), or Other. DESQview provides a graphics driver (GRFxxxx.DVR)

~Begin footnote~

Drivers for Genius and Wyse 700 monitors are available separately, at
additional cost, from Quarterdeck Office Systems,

~End footnote~

which is loaded automatically when you start up DESQview. If you select
Other, you can supply a driver by entering its name in Current Graphics
Driver.

~Subhead~ Display Text and Graphics?

 If you run graphics programs, you can controll whether you want DESQview to
switch back to text mode, or remain in graphics mode, when you switch from a
graphics program to a text program:

~Item~ Y specifies that, when graphics and text are both displayed on the
screen at the same time, the textual information should be displayed in
graphics mode. This has the advantage that you can leave graphics information
on the screen for reference while you work in a text program in a small
window.

 It has the disadvantage that programs running in text mode will generally
run slower when displaying information in graphics mode. (In particular, if
your PC has a slow processor, you may find that text programs run too slowly
when EGA-or VGA-mode graphics are on the screen.) It also has the
disadvantage that the colors used in graphics windows ~dash~ called the
palette ~dash~ may change. (However, they're restored when you switch back to
the graphics window.)

~Item~ N specifies that, when you switch from a graphics program to a text
program, the graphics information should be hidden by the graphics curtain.
(Some EGA and VGA modes force the curtain even when this option is ON.)

~Subhead~ Synchronize?

 Some types of monitors require the software to provide synchronizaiton
during video trace. If you get "snow," your monitor requires synchronization.

~Subhead~ Screen Blanking?

 You can tell DESQview to blank your screen when you leave you PC idle for
given number of minutes. This "screen saver" feature helps prevent burn-in.
To restore your screen after it's been "blanked,"  tap any key ~dash~ we
recommend the Shift key.

~Heading~ Advanced Option: Window Positions

 The Window Positions option lets you specify the nine predefined window
positions used by DESQview when it opens a window and when you use the
Position command on the Rearrange menu (see page 52).

When you open a window, DESQview uses the position information you specified
on the Change a Program menu for that window to determine its size and
position on the screen (see page 127).

However, if you haven't specified a position, DESQview uses one of its nine
predesignated positions for the window, in round-robin fashion.  To change
any of the nine default positions, enter the new positions you want:

~Item~ Row and Column specify the position of the top-left corner of the
window, excluding the frame (if any).

~Item~ Height and Width specify the height and width of the window, excluding
the frame (if any).

The top-left corner of the screen is 0,0. Your position settings must specify
a full-screen window or a window small enough for a frame to be drawn on all
four sides:

~Item~ A full-screen window must start at 0,0. For example, the standard
25x80 full-screen window is 25,80,0,0 .

~Item~ A small window must start at 1,1 or greater, and have a height and
width that allow room for a frame. On a 25x80 screen, the largest "small"
window is therefore  23,78,1,1.

 Programs written expressly for DESQview may create multiple windows,
override the window position settings you specify, or create windows without
frames. When a program has multiple windows, the Window Position settings
apply to the main (task) window. If the main window is a "small" window, but
has no frame, it may be positioned at 0,0.
