Hi,

I am a new TI Voyage 200 user (got mine a few days ago).

I am trying to learn TI BASIC as fast as I can, since I want to encourage students to learn how to program their calculators as an incentive to learning Visual Basic .NET (which I am supposed to teach them). Since my students are not that much interested in programming and offer much resistance to it, I tought that I could get some motivation out of them, if they could see the benefits of programming i.e. their calculator.

However, there is one thing I have no idea, yet. How does one use arrays?

I believe that this is done with lists in TI Basic, but I have no clue on that and would appreciate some examples.

Imagine I have an array like this:

A 10 20 30

B 11 22 34

C 09 65 27

D 93 48 70

etc.

Now I want the use to type in the "name" (letter from A to D) and make a calculation like:

SOLVE(INTEGRAL(x_1*t^3+x_2*t^2-x_3*t,t,100,200))

where:

x_1 = the first number of the line "name"

x_2 = the second number of the line "name"

x_3 = the third number of the line "name"

In VB I would to something like this:

```
name = InputBox("Select name")
for a=1 to 10 ' Imagine there are 10 items stored
if table(a,1)=name then
x_1=table(a,2)
x_2=table(a,3)
x_3=table(a,4)
end if
next a
...
```

Thanks,

vma
