Arrays are done in a similar ways, the only difference is that they can store multiple information into a single word. For example I'll make an array filled with numbers.
DIM Number[2]
Now I should have a list of 3 numbers.
To change these numbers I would say..
Number[0] = 1
Number[1] = 2
Number[2] = 3
