Programming Is a Creative Process
As you may have observed, programming the HP-65 is sur-
prisingly easy to learn. Once you learn the operations, and follow
the few rules, a whole world of possibilities is open to you. We
have purposely presented the calculator with minimal use of
formulas in case some of your mathematical training has dimmed
by lack of use. You can adapt what you have learned here to
your own purposes. In case you write a program that exceeds
memory, remember that most programs can be shortened upon
reexamination. Impromptu programs prepared for special pur-
poses are usually faster to program and debug. Larger general
programs can take considerable persistence. Good luck!
