To use an array object like this you need to get and set the value at x, xy, and xyz.
Since you only have 6 items to track that shouldn't be too bad, but a huge array with all three dimensions could add a lot of memory, and processing.
You would then set up a loop to set x at loopindex, x,and y at loopindex, and x,y,and z at loopindex.
....Might want to take a look at the Ini object.
