This is a shortcoming of DOS. Each program has its own local copy of the
environment, and it is generally only possible to modify your own copy.
After your program terminates, all changes are lost.
Having said that, there's a moderately well-known hack involving INT 2Eh
which does this. I don't know exactly how, but try Ralf Brown's Interrupt
List and/or some DOS hacking newsgroup.
There's a good chance it's not worth your effort; perhaps try to think of
some other method for accomplishing what you want.
