Running WordPerfect 6.0 for Windows under OS.2
Running WPWin 6.0 under OS/2 2.x requires a special setup. Most
of the information presented here is specific to OS/2 and is not
found in the reference manual.

The minimum or suggested settings can prevent several serious
problems that may occur when running WPWin 6.0 under OS/2.
Customers who run WPWin 6.0 with the default WIN-OS/2 settings
have experienced frequent General Protection Faults (GPFs) and
"out of memory" errors. These problems commonly happen while
trying to print, using Grammatik, editing large documents, or
doing anything that makes heavy use of memory. Giving WPWin 6.0
more memory usually solves these problems.
Even if you have not had any problems with WPWin 6.0 in a WIN-
OS/2 session, it would be a good idea to use the minimum or
suggested settings for more efficient performance.
Every icon that starts a Windows program from the OS/2 desktop
has its own WIN-OS/2 settings. To change the settings for WPWin
6.0, the first step is to create an icon that starts WordPerfect.
Create an icon by migration or by dragging out a template. To
migrate WPWin 6.0 to the OS/2 desktop, click on the following
nested icons in the listed order: OS/2 System, System Setup, ane
then Migrate Applications. Refer to your OS/2 documentation for
further information on migration and templates.
Next, you will need to change the WIN-OS/2 settings that apply to
WPWin 6.0.
1 Click the WordPerfect for Windows program icon once with the
right mouse button. A pop-up menu will appear next to the
WordPerfect for Windows icon. You will see an arrow next to
the Open selection.
2 Click once directly on the arrow to bring up a submenu.
3 Click the Settings option in the submenu, and a settings
notebook will appear. Clicking the tabs will turn the pages
of the notebook.
4 Click the Session tab.
At this point, you can select which screen mode you would like to
operate under. The options for WPWin 6.0 are either WIN-OS2
Window or WIN-OS/2 Full Screen.
5 Select WIN-OS/2 Full Screen.
6 Click the rectangular WIN-OS/2 settings... button. A long
alphabetical list of settings appears. The following list
details the WIN-OS/2 settings that should be changed for the
optimal performance of WPWin 6.0:
DOS_FILES
70 DOS_FILES are usually sufficient. Setting it higher
will not increase performance. However, in some
circumstances, OS/2 will not give the WIN-OS/2 session
all of the requested files. To compensate for this, we
recommend setting DOS_FILES to 100. If any of the
following error messages still occur, set DOS_FILES to
255 (the highest value allowed).
∙ ...insufficient file handles...
∙ Cannot initialize, most probable cause...
∙ Not enough local/global memory...
DPMI_MEMORY_LIMIT DPMI_MEMORY_LIMIT is the total amount of
memory (measured in megabytes) available
to the WIN-OS/2 session. With many
systems WPWin can get by with 6, but
setting this number to 8 will further
improve performance without inhibiting
other programs. Set DPMI_MEMORY_LIMIT
to 8 even if the machine only has 6M of
RAM. OS/2 will create virtual memory on
the hard drive to make up the
difference.
Even more DPMI memory will be needed if other Windows
programs will be running in the same WIN-OS/2 session.
DPMI rule of thumb: DPMI_MEMORY_LIMIT should be at
least 2M higher than the sum of XMS_MEMORY_LIMIT and
EMS_MEMORY_LIMIT. Note that XMS and EMS memory limits
are measured in kilobytes: 1024 kilobytes = 1 megabyte.
EMS_MEMORY_LIMIT EMS stands for expanded memory. WPWin
6.0 does not use expanded memory. Most
users should set this to zero.
NOTE: Running any Windows program that uses EMS memory
in the same WIN-OS/2 Full Screen session with WPWin 6.0
would be the only reason for setting EMS higher. 2048K
(i.e., 2 megabytes) is usually sufficient. After you
raise the EMS_MEMORY_LIMIT, review the DPMI rule of
thumb: DPMI_MEMORY_LIMIT may need to be raised as well.
IDLE_SECONDS IDLE_SECONDS is the number of seconds that
must pass before OS/2 begins monitoring the
application for idle detection. An
application is considered idle when it is
repeatedly polling the keyboard for user
input. Constant keyboard polling can bog
down the performance of concurrent
applications. When OS/2 determines that an
application is polling too much, it lowers
the application's priority in order to give
other applications better performance.
With the default settings in effect, OS/2 mistakenly
thinks that WordPerfect is idle when it is performing
such functions as text conversion or merging. This can
turn what should be a 4-second operation into a 1-
minute operation! Setting IDLE_SECONDS to 5 means that
OS/2 will wait at least 5 seconds before lowering
WordPerfect's priority.
IDLE_SENSITIVITY The value entered for IDLE_SENSITIVITY
represents a percentage of the total
amount of CPU time given to an
application. A value of 95 means that
WordPerfect can spend up to 95% of its
allotted time polling the keyboard
before OS/2 lowers its priority.
Setting IDLE_SENSITIVITY to 100 disables
idle detection since no application can
spend more than 100% of its allotted
time polling.
XMS_MEMORY_LIMIT WordPerfect uses XMS memory. Most
customers have been able to eliminate
out-of-memory errors with
XMS_MEMORY_LIMIT set to 4096.
Nearly all Windows applications use XMS memory. If
WPWin 6.0 is running at the same time as other
applications, then set XMS_MEMORY_LIMIT higher■we
suggest anywhere between 6144 and 16384. You may have
to raise DPMI_MEMORY_LIMIT to make sure that the DPMI
rule of thumb is not violated.
If, after making these changes, you are still having problems,
you need to make sure that the new settings are in effect. The
following conditions may cause problems:
∙ The settings you changed are saved with the WordPerfect
for Windows icon, not with WPWin 6.0. Should you need
to create another icon that starts WPWin 6.0, be sure
to change the settings for the new icon. If WPWin 6.0
is started from the WIN-OS/2 Program Manager, or from
an OS/2 prompt, the desired settings will not be in
effect.
∙ Starting WPWin 6.0 with the WordPerfect for Windows
icon does not guarantee that the WIN-OS/2 session will
use the new settings. Before you start WordPerfect,
make sure that a WIN-OS/2 session is not running.
Also, verify that no other Windows software (even the
Windows Clock) is running. Then start WPWin 6.0 by
double clicking on the WordPerfect for Windows icon.
The new settings should be in effect.
There is a way to make sure that the WordPerfect for Windows icon
will always start WPWin 6.0 with the desired settings, even if a
WIN-OS/2 session is already running:
1 Open the settings notebook for the WordPerfect for Windows
icon.
2 Click the Session tab.
3 Click the box next to Separate session.
