Thanks for your reply. Ah well, worth a try. I'm going to keep plugging 
away at this. My next goal is to produce a C++ example that doesn't 
require the STL, and after that maybe an example in plain C. Reducing 
the amount of code and eliminating number dependencies should help us 
see what's going on more clearly.

I'll post back here if and when I make more progress.

Dave.
