Is there a way to store a list when programming a TI-83+?

Question

Out of curiosity, I'm beginning to learn how to program my TI-83+ calculator. Part of my latest program involves storing numbers in a list. How can I add items to a list on a TI-83+ and how can I loop over them/access them?

You need first to define the size of a list like this :

 

3->dim(L1 

(if you forget, you will have an ERR:Invalid Dim)

 

Press enter and you get a "10" as answer (don't worry it's normal).

 

You can find dim( in the [Catalog] and -> is "[STO->].

 

Then you could fill the list with some data like this :

 

2->L1(1)

3->L1(3)

Now When you print L1 you get :

 

{2 0 3 0}

First index is L1(1) not 0 (as usual).

 

You can delete the list by using DelVar :

 

DelVar L1

You can fill it with Fill, sort it, convert to matrix .... Simply go to the List menu (2nd + Stat).

 

You can iterate on the list using a for loop (no foreach, use dim(L1) for the upper bound).
