environment variable question

I have an old (1991) DOS 'EXE' program witch works in conjunction with batch files. The EXE puts certain information into an
environment variable, the BAT file executes the variable.

This setup does not work in W2K4 (or XP1). I'm wondering why. It appears the OS will not allow the EXE to write a variable to the
environment (all in a 'dos' window), but I am not SURE this is the case. Oddly, BAT files CAN write to the environment within the
session. I am wondering if the problem is the WAY the EXE wants to write a variable into the environment or something else.

Can someone enlighten me as to what is actually going on?

Thanks
Vic
