I'm perhaps showing my ignorance here but I fail to see what the fuss is 
about. You have the *correct* answer in regs.X and regs.Y. Let's forget 
about printing for the moment, since that's a completely separate problem; 
the only issue is how BASIC09 is treating those quantities. You already know 
the problem - they're two 16-bit signed integers, and it seems you can't 
change that.

So what's the issue with, for example, assigning to a real and applying the 
maths to fix it? It seems everyone here wants to take a sledgehammer to 
crack a nut!?!
