It does.  Thank you!

One last question: what is the scope of variables in remind?  There's no 
discussion of scope in the man page, suggesting that there's only global 
scope, and that I should "UNSET meeting" before the ENDIF for 
cleanliness.

Is that correct?  A quick test shows that "meeting" is still set outside 
the IF block if I don't UNSET it, so it's not block scope, but I haven't 
used variables before so there might be some complexity I'm missing, or 
just no scopes/only global scope.
