Let's say that based on a condition inside Macro A, I want to
immediately switch over to Macro B instead without processing the rest
of Macro A. How do I do this in POV-Ray? In a normal scripting language
I would simply use a return statement to stop Macro A, but POV-Ray
doesn't have a return statement.

Okay, I got lucky and found the description of the #break statement in
"3.3.2.6.4 The switch, case, range and break Directives".

To me that sounds less like luck, and more like a case of the document
writer having done his job ;)

Very interesting. I didn't know this was possible 'within' a macro. Good to
know.

No, I got lucky because I was looking for something unrelated, and just
happened to glance at the note.
