[General] Question about variable arrays

Level 20
Jun 26, 2020
When you create a variable array it has a size, so by logic, you can't never use a index the pass the size, exm you create a variable with size 10 so you never can use a index 11, but sometimes I see you can do this, if the size is 1 at least I think, is this because a variable array with size 1 means something or what?
