I'm afraid this doesn't do what he wants. Each process has its own copy of
the environment, which is usually propagated to its children. But what the
original poster wants to do is change a *parent's* environment, specifically
that of the master COMMAND.COM interpreter, so that *every* process, not
just his program's children, get the change. This is actually not supposed
to be possible to do, but there are ways...
