Get More Environment Space

Question:

I have a big DOS program that runs ok on W95 until I run it from a WBT script. Then when it loads there are a couple of messages "Out of environment space". I used to get this message anytime I ran the program (from the desktop, that is) until I tuned the memory on the PIF file. I wouldn't care about the message, except that after a few iterations of the script, the DOS program aborts. Is there any way to cure this?

Answer:

A little more tuning may be in order.

I would go into your autoexec.bat and add a few lines like...

SET DUMMY1=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
SET DUMMY2=BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB

Do about 5 or 10 of those with longs strings of letters.

Then write a DOS BAT file to launch your DOS program. At the top of the DOS BAT file clear out the env variables. It might look something like...

SET DUMMY1=
SET DUMMY2=
SET DUMMY3=
MYDOSPROG.EXE

Then change your WinBatch script to call the DOS BAT file. Be sure to also tune the shortcut to the DOS BAT file. The SET statements should free up a little environment space for the program.
