Help!!$% When I run a batch file to envoke a non-Windows
application which must set an environment variable, I find that
Windows ver. 3 spawns a shell with only 160 bytes of environment
space, despite the fact that my config.sys file sets the original
environment space to 512 bytes. As a consequence, the non-Windows
application is unable to run for lack of environment space. The only
solution I have found so far is to reset the Path and other
non-related environment variables within the batch file being spawned,
so that the new application will find some room within the 160 bytes.
Isn't there some way to tell Windows to run batch files with more
environment space available to them?

Not that I'm aware of. (I'm no expert!) But what I do is set an environment variable in AUTOEXEC.BAT, that is just filler. Then I can clear this one to free up environment space in Windows. SET DUMMY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX... You get the picture... ----------------------------------------------------- Gordon S.

On a case-by-case basis, there is. In Program Manager, choose File Properties. Edit the Command Line to say "COMMAND.COM /e:xxxx /c foo.bat" where xxxx is how many bytes of environment space you want. I use 1024. From then on, when you double-click that icon, the batch file will run with sufficient environment space. To ensure that your DOS Prompt has enough environment space, either edit its Command Line to say "COMMAND.COM /e:xxxx" or make a PIF file for it that includes that Command Line. I use the PIF file, since that way I can assign a hot key to zap into that DOS shell. For more information on command-line switches to COMMAND.COM, read your DOS manual. This material belongs in some kind of Frequently Asked Questions posting. -- Steve "I don't speak for Microsoft" Hastings ===^=== ::::: uunet!microsoft!steveha steveha@microsoft.uucp ` \\==|

Putting SHELL = COMMAND.COM /E:XXXX/P in your config.sys provides a general solution also for the DOS versions that support SHELL.

I don't know if this is the best way to work around the problem, but it works. In your AUTOEXEC.BAT create an environment variable like set RESERVE=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx (you can set more than one depending on how much space you need). Then in the shell bat file, execute set RESERVE=, which releases the space for use in the lower level of shell I agree it would be better if Windows allowed direct control, but . . . ------------------------------------------------------------------------- Reed Jacobson reedj@hplsla.hp.com
