How to make a complete application?

1-I have to create the appdir folder too, not the calculator.
2- When using the AVars and AFiles commands, files with * .hpappvar extension are automatically created, or are not they?
3 - The icon I do understand that it is only saved inside the file folder and already.
4-When are the files with * .hpappvar and * .lib extensions created? What are those * .lib files, the calculator creates them or are they made out of it?

It would be a pleasure that when you have time and you have made applications as good as "Equation Library" and "Graph3D" that I have in my calculator you could put a very small example of how to build a mini application with all those extensions putting the detailed steps to clarify My doubts and maybe the many others that are beginning in the programming of this extraordinary calculator, since the manual does not bring many examples of this !!! Thanks again.

1. No, the hpappdir folder is created for you when you transfer the app out of the calculator/emulator onto the PC/Mac.

2. Yes; I think only one file is created that houses all the variables.

4. The hpappvar file is created as soon as you create an app variable via: AVars("myvarname"):=0 (or whatever you want to store). The lib file is what I created myself using the emulator and typing:

AFiles("Equation Library.lib"):=<list that I copied from a text file and pasted into the emulator>

As for the video, here's a super old one that gets into a bit of detail on replacing the Plot, Symb, etc functions:

I'll do another one since that example was done before the whole hpappdir paradigm.
