I guess you should check whether, prior to launch your .BAT file, the 
CHERE_INVOKING variable is already defined in the environment in lowercase.

I mean that if I do:

     SET chere_invoking=0

and then later with the same environment (or inherited one):

     SET CHERE_INVOKING=1

I have "chere_invoking=1" in my environment (in lower case).

     C:\>set chere_invoking=0

     C:\>set CHERE_INVOKING=1

     C:\>set | grep -i chere
     chere_invoking=1

So before you launch your .BAT file do a:

     set | grep -i chere

and see whether CHERE_INVOKING is already defined in lower case in your 
environment.

Ciao,
     Danilo
