Advanced Variables

For some of you, this might not be advanced.
But for me, it is. I'm asking about being able to add a variable via code, instead of coding the variable itself manually.
I'm looking through the LUA docs right now, but no avail.

Solved.

Nevermind, I found something that I can use for this.

At the simple level, you can use numbered tables.

If you mean actually new variable types, the best you can do is metatables, but they still function as tables at some level.
