I have a modified version of the standard Array.au3 file that comes with AutoIt3. Most of the original _Arrayxxx functions didn't/don't support 2D arrays when using them. I have welded on the ability to use most of the existing functions with a 1 or 2D array. There are a couple of the _Array functions that I have not added this functionality to, mostly because I don't think it would be necessary and/or helpful for them to have it. Here is a list of the functions included in the Array.au3 file
