Then, for maximal portability, you'll have to write those values to a
temporary .bat file, and 'call' that from the controlling one after
the .exe is done.  

Commands can't usually change environment variables as seen by another
process.  Not even in DOS.  There are undocumented methods of doing
that, of course, but unless there's very pressing need, you should
avoid those.
