Optimizing performance with loop unrolling

Yeah, that is the crux of the joke.

Whoever wrote this program apparently knew just enough about HP 67 programming to have both LBL A and LBL B for two different functions, but didn't know that those 5 steps could be repeated indefinitely with a simple GTO.

I wonder if this person ever adapted the program for the greatly expanded memory of the 41!
