Monks,

I have 3 arrays of spatial data, @x @y @z. I want to sort them so that they are sorted first by @z in ascending order and then by @x in ascending order. So if I have:

@x = (0, 18, 36, 0, 18, 36, 0, 18, 36, 0, 18, 36, 0, 18, 36, 0, 18, 36);
@y = (0, 0, 0, 18, 18, 18, 36, 36, 36, 0, 0, 0, 18, 18, 18, 36, 36, 36);
@z = (25, 25, 25, 25, 25, 25, 25, 25, 25, 20, 20, 20, 20, 20, 20, 20, 20, 20);

Then after sorting I am looking for:

@x = (0, 0, 0, 18, 18, 18, 36, 36, 36, 0, 0, 0, 18, 18, 18, 36, 36, 36);
@y = (0, 18, 36, 0, 18, 36, 0, 18, 36, 0, 18, 36, 0, 18, 36, 0, 18, 36);
@z = (20, 20, 20, 20, 20, 20, 20, 20, 20, 25, 25, 25, 25, 25, 25, 25, 25, 25);

sorry for the long arrays and the easy question.
