i started the way John is explaining. When the Prime came out there were no other documentation and the guide had this chapter which is still valid.

I personally - years laters - studied other people very simple applications to understand how to do it like the one you indicated in your thread.

i usually consider simpler application just to understand the logic like games or other apps like this. one i remember i studied for example was GEOGAME by Bernard Michaud.

the code in pretty small, simple and it shows how to handle the graphic.

Dear Mr. Giancarlo,
Where do I start? The apps I have installed on my Prime are not visible in the Program catalog, and have the extension .hpappprgm, while programs have the extension .hpprgm. So for every app I install I can't see the source code. So how am I supposed to learn how to make an app? Sincerely, Karel.
