Scratch

Yes, that's generally what they're used for. That's how a lot of projects operate, because you can't instantly make variables but you can instantly make items in a list, so you can have as many variables (items) as you want.

row * 10 +column to build a 2 dimensional array from a  one dimensional - having 2d arrays would be better but my understanding arrays of arrays don't exist yet.

Arrays within arrays... Makes me think of the way I accidentally crashed scratch MULTIPLE TIMES. Make a variable endlessly add 10, then make another variable that is the first variable multiplied by 10 or so. Then make the first variable set to second variable times 99999 or something like that. 5 seconds later... SCRATCH CRASHED!!!

Edit: I know this isn't what you mean by array within array but... Put a list inside a list? Ok it might kinda be what you mean...

The major advantage to arrays is that they are indexable and operate as portions of a set of values rather than a single one. You see, you cannot get, say, the score as it was 3 seconds ago with variables, as you don't know which one it was stored in. However, with lists, you just add to it every second, and take the third last.
