The following information applies to:
- Microsoft Windows operating system versions 3.0, 3.0a, 3.1, 3.11
- Microsoft Windows for Workgroups versions 3.1, 3.11
SYMPTOMS
========
You may receive the following error message when you start the MS-DOS Prompt or
an MS-DOS-based application:
Not Enough Environment Space
CAUSE
=====
The above error message may occur if you are running Novell NetWare and have not
installed Windows with Novell connectivity, or if the MS-DOS-based application
you are trying to run requires more than 256 bytes of environment space.
WORKAROUND
==========
- If Windows 3.0 or later is running on a Novell NetWare network, make sure
that the appropriate network selection is made in Windows Setup.
- If the MS-DOS-based application requires more than 256 bytes of environment
space and you are running Windows 3.1 or later, add the following line to the
SYSTEM.INI file under the [NonWindowsApp] section:
[NonWindowsApp]
CommandEnvSize=1024
1024 bytes should work properly; however, the setting can be set as high as
32,768 bytes. The value must be either zero or between 160 and 32768.
This is a global setting that affects all virtual machines (VMs).
- With Windows 2.x and later, you can create a program information file (PIF)
to increase the environment space for the single application. Use the
following settings in the PIF:
For Windows 3.0:
----------------
Field Setting
===== =======
Program FileName Command.COM
Window Title My Program
Optional Parameters /e:2048 /c C:\mydir\myprog.exe
Startup Directory C:\mydir
For Windows 2.x:
----------------
Field Setting
===== =======
Program Name Command.COM
Program Title My Program
Program Parameters /e:2048 /c C:\mydir\myprog.exe
Initial Directory C:\mydir
"/e:2048" is the size of the environment space in bytes; this value also
ranges from 160 to 32768.
"Mydir" is the name of the directory that contains the executable of the
program.
"Myprog.exe" is the name of the program.
"/C" specifies that the command processor is to execute MYPROG.EXE and then
terminate itself.
