Oh, I have some programming theory, Neil, it's just highly dated. :-) My
interest in it ended when I graduated from college and went back to being a
hardware tech.

My code is safe, documented line-by-line, and vetted by other sysadmins. It's
just linear and monolithic vs. modular and reusable - think "top-down" method.
It may not be efficient, but it works, and anyone can read it and understand
what it's doing.

Now that I can understand. Thanks.
