Subject: Shorter APPT, APDIR (this is a LONG message)
Date: 29 Mar 90 20:13:24 GMT
Organization: California Institute of Technology, Pasadena

After getting the Appointment application (APPT and APDIR) from the
HP bulletin board and kermiting it over to my calculator, I found
that I didn't have much memory left.  With a few other things loaded
in as well (the stopwatch, some of my own things), I started thinking
about buying more memory for the thing.  Then I looked at the
programs in APDIR, and decided it was really a ploy to make me get
more memory.  It almost worked too!

Without changing the functionality whatsoever, I reduced the size of
APDIR from 13714 bytes to 8173.5 bytes.  I did this by rewriting
parts of the programs, putting them all in one directory, and
combining some programs (and even fixing a bug or two here and
there).  It is even a little faster now.  The thing really deserves a
total rewrite, and I estimate it could be made faster and more
functional in less than 5 or 6K bytes.  But, alas, I don't have time
for that. Anyway, here is the shortened version, first APPT and then
APDIR.
