Here are my two cents (we're getting rich :) )

Eehm, yes? What did you have in mind then?

Do you happen to use an 83-? Omnicalc is an application, that's a special
type of assembly program that runs straight from flash rom, so it will only
work on calcs that have that flash rom (duh), in this case the 83+ / 83+SE.
There is no easy way to use this function on a standard 83, so let's just
forget about it.

Yes, it works, however, it is SLOW. Calculating regressions is not as fast
as just adding a bunch of numbers. Especially if you're gonna use a lot
of numbers, this will slow the game down noticeably.
The only "problem" I see with Romman's solution is the extra space, but
I fail to see how a quick, short piece of code with one slight imperfection
would be worse then a rather slow, long piece of code, that uses a score
of extra variables.

Could you please tell exactly what your problem with our solutions is,
because I'm not sure I get it.
