If you're using Unix (I think even a dos shell can do this sort of thing too), why
couldn't you just do a system call to the shell?
i.e. system(" export MY_Variable=whatever ");
I haven't tried this, but it sure seems like it would work -- provided you're
running and exiting the script as the same user. This is an interesting one; I'll be
interested to hear any and all feedback.
