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.
