the array.copy is not an new array with a copy of the content.
It is the same but with a different name.

arrB = arrA.copy()
arrB is the same as aarA only the name differs.

The exact name should be .Clone() I think.
or arrB.Alias( arrA ) or arrB.Link(arrA)

A copy is an new instance of it with the content of the source.
