TITLE : Using DESQview and DESQview 386 with Paradox 3.5




When using DESQview and DESQview 386 to run Paradox take the
following into consideration.

DESQview and Paradox on XT and AT Compatible Computers

DESQview can run Paradox 3.5 on these computers but the overhead
from DESQview is as much as 135KB. The amount of overhead can be
shrunk to 75-80KB on AT computers when either HIMEM.SYS or
QEXT.SYS are loaded by your CONFIG.SYS file. Paradox 3.5 must be
run in Real Mode with DESQview on either of these two computers.
Because of this functional limitation when running Paradox under
these two configurations there may not be enough memory for
Paradox to load and run. To help ensure Paradox runs under one
of these configurations remove any device drivers that are not
absolutely necessary for operation of the computer so Paradox has
more memory to operate in.

Here is how to configure DESQview to run Paradox 3.5 on XT or AT
compatible computers:

1. Install Paradox 3.5 according to the installation
instructions in the Paradox Introduction manual.

2. From the DESQview Main menu, choose "Open Window."

3. If you are upgrading from Paradox 3.0 to 3.5, select
"Paradox 3" from the file list, then choose "Change a
Program." If you are installing Paradox for the first
time, you first have to use "Add a Program" and select
"Paradox 3" to add the program name to this list. Do this
by starting from the DESQview menu and select Open Window
| Add Program, and select "Paradox 3" from the list. When
you do this you are prompted for the directory where
Paradox 3.5 is stored. Enter the directory and press
. Next select Open Window | Change a Program and
enter the two key code for Paradox 3. You see the program
Standard Options Screen.

4. Type the program name or any batch file name you use to
invoke Paradox, the full path name, and any command-line
parameters you use. Be sure to include the -REAL
parameter in the parameters list. Set Memory Size (in K)
to 512. Set the Standard Options switches as follows:

5. Press for the Advanced Options screen. Set the

Max Expanded Memory 512*

Set the switches as follows:

* Max Expanded Memory can be set higher or left blank.

6. Exit "Change a Program" or "Add a Program" and start
Paradox in the usual way under DESQview.

DESQview and Paradox on 80386 or higher Computers

When DESQview is bundled with QEMM-386 it becomes a much more
effective and efficient multitasker than using DESQview by
itself. In this configuration DESQview becomes compatible with
the method Paradox uses to run in protected mode. This means
Paradox can be run in protected mode while other programs run at
the same time.

Here is how to configure DESQview to run Paradox 3.5 in Protected
Mode:

1. Install Paradox 3.5 according to the installation
instructions in the Paradox Introduction manual

2. From the DESQview Main menu, choose "Open Window."

3. If you are upgrading from Paradox 3.0 to 3.5, select
"Change a Program", then select "Paradox 3" from the file
list. If you are installing Paradox for the first time,
you first have to use "Add a Program" to add the program
name to this list. See step 3 in the first half of this
TI for full details. You are brought to the program
Standard Options Screen.

4. Type the program name or any batch file name you use to
invoke it, the full path name (including file name), and
any command-line parameters you use. Set Memory Size (in
K) to 440. Set the Standard Options switches as follows:

Writes Text To Screen [N]
Displays Graphics Info [Y]
Virtualize Text/Graphics [Y]**
Uses Serial Ports [N]
Requires Floppy [N]

5. Press for the Advanced Options screen. Set the
following parameters:

System memory 0
Max Program Size (in K) 640
Script Buffer Size 1000
Max Expanded Memory 512***

** If Paradox 3.5 is going to be run in real mode set
this option to N.
*** Max Expanded Memory can be set higher or left blank if
all available memory is to be used.

6. Exit "Change a Program" or "Add a Program" and start
Paradox in the usual way under DESQview.

As an additional tip for users who need to run the DOS SHARE
command, be sure to start DESQview with with the command line
option /DT (e.g. DV /DT) so DESQview recognizes the existence of
SHARE.
