    Modify TI89 Menus

    Does anyone know how to modify the TI89 Menu? Google did not help much.

    For instance, to reorder the list in [2nd][tex] and set the list to:
    1: Algebra
    2: Trig
    etc?

    People say the TI89 is the most flexible of all TIs. Can anyone prove this?

    Thanks.

    There is the "Custom Menu" accessed by typing [2nd][HOME]. This is not exactly what you're asking but it plays the same role. This is a menu replacing the main menu (on the top row) and you can edit it using a program: the procedure is described in your user manual, or on page 303 (and following) of the online TI 89 manual that you can download from here.
    Have fun making your own menu!

    you have to write a separate program to do this the code should look like this

    :Custom()
    :Prgm
    :Custom
    :Title "one of the headings that you want"
    :Item "any item you want on the list"

    you can have as many items as you want then repeat the process to make more headings and then their items then end with
    :End Custom
    :EndPrgm

    now all you need to do is to execute this program then hit 2nd home and your custom home will be available i recommend making a tab for you common programs such as any quadratic equations or what not programs



    hope this helps
