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.
