I didn't change anything, actually -- it never printed the "8/2 Updated
database" string. It prompted with the "Enter a date and note:", I typed
"Uh." and that was it. Maybe my version of perl doesn't have a good
Term::Readline::Perl? How do I find out? I'm on OS X 10.5, which is still
at perl 5.8.8.

Makes sense.

I've never used objects -- do I need to understand them to use
Term::Readline?
Thanks again, I really appreciate it.
