Ah - nice idea! You mean make a grid of values by using an array (Y) of pointers to lines (X) of values (Z) and so keep the speed of access whilst keeping the size to a minimum (overhead of extra 8 bytes per line max). I like it!
Thanks,
Nick
p.s. I just went over the 2Gb mark again with non-gridded data but will attempt to apply the same logic.
