  My older brother has a request; since he does not bother to read the net
(he feels my time is worthless enough :) he had me post this, and read all
the replies.  I have been watching for subjects which addressed this question,
and have seen none; so I have posted this article.  If you feel that this info
is current enough to do a followup, fine; otherwise, you can mail me your
answer, or mail it directly to him (acct. "webster", same path).
  Here is his question:

Can someone tell me a way to change an environment variable from
within a C program, and have the change be permanent when the program
terminates?  Using the putenv() call only changes the copy of the
environment local to the C program; I need a way to change the environment
of the COMMAND shell which exec'ed the C program.

A magazine I read suggested this as the solution:

system( "SET FOO=BAR");

but this did not work for me.  The environment remained unchanged when
the program terminated.
