AC1 contains 20 arrays. AC2 = AC1. Changing an array in AC1,
changes the array in AC2 as well.
I want to add arrays to the beginning or end (or both) of AC2
without changing AC1.
So instead of AC2 = AC1, AC2 = clone(AC1) (using the clone
function in the Docs).
But this disconnects the underlying arrays as well as the
Is there a way to change AC2 without changing AC1, yet still
allow a change in an array in AC1 to also change the same array in
AC2, no matter where it is now located in AC2?
