Hmm.. I suppose you could sort any dimension...

If you had:

DIM $a[$x,$y,$z]

You could sort any of the 3 dimensions.. (This would be a 0 index sort, kind of like starting in the corner of a rubik's cube and labelling 0 for each axis.) The problem would be that for each item in the $x dimension that you sort, $y*$z items would have to be moved as well. In addition to that, you might want to sort a different index. Unfortunately, KiXtart will not allow you to operate on a section of the array at a time. You have to assign values for each and every slot.
