If you have enough memory, how about not returning to the DOS command
processor by leaving your program, but by creating a child process and
running COMMAND.COM which would then be passed a copy of your expanded
environment?  Have not tried this since I don't need the capability, but
it seems a reasonable way to solve it if it works for you.
