Is that good code?

Man, just when I think I know something about anything. So an array isn't copied, even if it's not passed ByRef, unless it's manipulated inside a function?

This works anywhere, not for function parameters only IIRC.

Global $a1[10000]
Global $a2 = $a1

$a2 will 'point' to $a1 until you attempt to modify any of them. Only then a copy (followed by the modification) will take place.

Kind of anyway You'll find that AutoIt uses copy-on-write optimization for arrays, so that unless the array is modified in the the function, the array never actually gets copied.

Oh, cool. Well, for certain values of "cool"; it isn't called "Mad COW" in C++ circles for nothing. Another reason why AutoIt isn't going to be multi-threaded any time soon, I guess.
