@#yolo A variable is, well, a value that can change. While an array is like a set of variables, where each position is like an individual variable. On some cases you will need more than 10 variables, so instead of doing this: Vl1 Vl2 Vl3 ... You use arrays like this: DIM Vl[3] And to access or setting data on it, you use the index [] from 0 to the size of the array: Vl[2]=5
