Thank you.  I learned something today that I didn't
expect to learn which is why I posted the question in the first
place.  I just wasn't thinking, I guess and used the all-caps
names to indicate that they stood for files.  If one collided
with an environment variable name, it could make the script fail
in strange ways that would be totally unpredictable, depending on
which variable one preempted.
