Vector arrays don't exist in SmileBASIC, do they?

I would say not it basic not object or c++ or java.

They do exist in C++. I'm still having a little difficulty understanding how to use them though.

A vector array as in an array that can be resized? Yes, it technically DOES exist. The PUSH command adds an element onto the end of an array, and the POP function removes the last element and returns it. UNSHIFT and SHIFT do the same thing, except at the start. These actions resize the array as well. Remember this ONLY works on 1D arrays. Example: DIM A$[0] PUSH A$,"HELLO!" PRINT POP(A$)

Oh, so that's what those do. I was about to ask that, but now I don't have to. Thanks!

ok if that right, then I should be able to read from a 2D array and push or pop to a 1d array for X and 1D array for y right if i got what your saying, right?

Are you talking to Alex or me?

You can't POP values off of a 2D array. All of these things work on 1D only.
