I would like to have my programs call on built in stuff in the calculator. I would like to see how the software on my calc does it. For example, if I want my prorgam to pop up the apps menu. Is there a way to see how it's done in the rom so that I can just make the same call or jump or whatever? (Again, this question is hypothetical, and not just for the apps menu. I want to be able to call any built in program) -SirKnight
