That's what I was afraid of.  Oh well.

The short answer is that my real situation is more complex than that :)
but yes, I can improve things.  And that's part of what I'm doing.

The variables were mostly just to make it modular -- change the start date
in one place and have it update in three automatically, things like that.
(The intent, of course, is that the computer do the work instead of me.)

The end date isn't necessarily known up front -- for example, if they close
due to snow, then we skip a week, but still have 8 classes.  You're right
(of course) that I probably want both SATISFY and UNTIL, though.

Now that you mention it, I wonder if I can use the choose() function
to just pre-populate a year-long class list, and have remind automatically
notice "lesson_num just passed 8, so go to the next class".  Ooooooooooo...

Thanks for the tips and the ideas.
