Edit: This is now part of beta 3.3.15.4 __________________________________________________________________________________________________
There is a _ArrayToString() but no _ArrayFromString(). ( searched in the forum and google )
The example is based on the _ArrayToString() help file, to show the reconstruction of the array.
#include <Array.au3>
#include <MsgBoxConstants.au3>
Local $aArray[20]
For $i = 0 To 19
$aArray[$i] = $i
