I finally worked on this a little last night and today since it might actually be useful to other students and professors on campus. I scrapped my original menu idea for a much simpler version. Now you can scroll through the tutorials and I made the setup relatively easy for adding new tutorials. There is also a filter option to view tutorials by category.

So some documentation since I haven't updated the readme:

There are two types of items that can be selected from the menus-- Tutorials and Menu Links. Menus have the following syntax:
Menu_0:
     .db "Menu name",0
     .dw number_of_items
     .dw Item_pointer_0
     .dw Item_pointer_1
     .dw Item_pointer_2
...
The item pointers point to an item of the types named above. Tutorials have the following syntax:
Tuto_0:
     .db "Item Name",0,0
     ;Tutorial data
     ExitTutor()       ;also .db 0
Menu Links have the following format:
MenuLink_0:
     .db "Item Name",0,1
     .dw MenuPtr

I also added a new tutorial function called Routine() which allows you to call tutorial code as subroutine. I made this because as I was adding some of the Linear Algebra commands, there was a bunch of duplicate code. Subroutines end the same way as tutorials, with ExitTutor(). Code will then resume after the point of the call.

Finally, I am also trying to keep in mind the goal of having external tutorials and a multipage app. Some of the source code is currently unoptimised since it is a one-page app, but once page boundaries have to be worried about, it will be useful.

EDIT: The original download had the wrong version of the app (correct source, though). It is corrected with an updated version.

Oh, that is an app that was causing trouble for somebody on TI-BD that I was investigating. I am actually supposed to delete that now that the problem is resolved

Oh, the app is not for public use, that is why (the PM 1.2 app).

Anyways, I figured out that the file I uploaded was the wrong version, so sorry about the crash to the two people that downloaded it :[ I updated it with the new version which has a few more tutorials and menu options. The current tutorials are:

Binomial CDF
Binomial PDF
Determinant
Integral
Matrix Inverse
Derivative
Normal CDF
Reduced Row Echelon
Hello World programming example

It is such a good idea !

Error : Selecting the "Determinant" tutorial, and pressed 2nd, then ON, the calculator was turned off and when I turned it on, I was forced to follow the key sequence and to be on a loop of incorrect calculation.

wow, that looks pretty awesome, nice work xeda!
