Guys, please. Of course I know that the Bubble is the worst sort in
existence for a large array, but it was the easiest to implement with the
array divided up into non-contiguous chunks. It works, but performance
is unacceptable. Basically I did it to get something working now, with
(hopefully) a better method coming later.
Now, I know a bit about heap, and it seems to require contiguous storage,
t do it's thing. As do most sorting algorythms. I need one that can
accomodate the difference.

If at first you don't succeed, destroy all evidence that you ever tried.
