I just spent a lot of time getting all the array loops to work without error,
and now POV complains
Parse Error: Expected 'RValue to declare', End of File found instead
or if I comment out the #end where it chokes, then I get "end of file reached,
but #end expected.
As far as I can see, all my #locals have a ; and all my #fors have an #end
Hoping someone can help me spot where in the chain it's all going wrong.
I'll keep hunting backward
(This is theird time I'm posting this - seems to be a problem getting it to
"take" via the web interface)

Because there is no RValue returned from computeControlPoints(K)
At the bottom of computeControlPoints, where you have
//return {p1:p1, p2:p2};
commented out, you need something there. Like
(p1[0])
if that were the value you were returning.

According to how it is used, your macro `computeControlPoints(K)` should
expand to a value, but it expands to nothing.

Fixed a lot of code, tried to get it all packaged up into a macro for repeated
use, but I'm stumbling on something again.
Scope, or the way I'm expanding the macro return value.
I define array CPX as the result of my macro's generation of array P[], but then
when I go to look at CPX it tells me it's uninitialized.
Also strange is that the message window doesn't even display the "i = " before
it terminates with an error at the NEXT line.
Can someone please school me?

"#debug" output isn't actually written until an end-of-line ("\n") is
output.
