Still doesn't really help. What's the while loop actually doing? Where's the data being stored, and how do you get it out?

Similarly for his quicksort example (http://www.rebelscience.org/Cosas/quicksort.htm) - from what I can see, there's no means to input or output whatever you're sorting - that part is all internal, and the only accessible parts are 'start' and 'done'.

I think you need to drag your understanding and drop it onto his concepts. You're far too bogged down with all of this "seeing". When are you people going to stop just seeing, and start truly knowing? Drag and drop your mind. It's the way of the future.

The way I understand it, components can share data.
