Someone already pointed out that this function as written still allows 
one divide by zero case. But I noticed in this function, and in your 
Scripters Scrapbook, that you still use the old HC form of returning a 
point. There's probably not much difference execution-wise, but I like 
the elegant Transcript comma operator, which lets us just write

     return x,y

Happy Transcripting,
