I just looked into seeing if it was possible to save the errorlevel after running python, and then restore it after clearing AAPARGS, and it is possible...

But, it looks like that's not even necessary. Apperently, Win9x does *not* change the errorlevel when issuing a set command like NT/XP does. To test it, run the following batch file (on a *fresh* command-prompt):

@echo off
echo Errorlevel: %errorlevel%
set AAPARGS=
echo Errorlevel: %errorlevel%
set AAPARGS=fs
echo Errorlevel: %errorlevel%
set AAPARGS=
echo Errorlevel: %errorlevel%

On my WinXP Pro machine I get:
Errorlevel: 0
Errorlevel: 1
Errorlevel: 1
Errorlevel: 1

And on my Win98 machine I simply get:
Errorlevel: 
Errorlevel: 
Errorlevel: 
Errorlevel: 

Note also that NT/XP only sets the errorlevel to 1 if AAPARGS is not yet defined, otherwise it sets it to 0.

So it seems that the slightly modified aap.bat I posted earlier should work perfectly fine on both 9x and NT/XP.

FYI, not that we seem to need it, but the errorlevel can be saved and restored like this:
set saveerror=%errorlevel%
rem Do stuff that messes with the errorlevel
set errorlevel=%saveerror%
