There are a lot more issues to cover, including the use of forms, menus and other resources, which is fairly important to any non-trivial program.
Regardless, I'm going to release this as it stands, so that people can start using what I have written so far.
You may wish to bookmark http://www.orbits.com/Palm/ and check back occasionally to see if I have released an updated version of this document.
Constructive comments sent to palm@orbits.com are appreciated.
