Yes, you introduced me to that a year or so ago, and I've been playing
with it. Routines for archiving data at the office, and I found a big
book on it at a yard sale, though I haven't had time to do much.

Yes, I recall FOR...DO from earlier batch language use.

Thanks for the explanation. Who was it said anything is simple if you
know how it's done? This calling itself, then deleting itself, is what's
called recursion, no? Neat idea.
