List Commands Library for 50g

RAND will never return 0 or 1. I remember from many, many winters ago. Alas, that is all I remember. So I had to look it up:

Random thoughts on HP48 random functions

Read the whole thread. Interesting stuff.
Basically, it boils down to the fact that a whole class of Random Number Generators use

x(n+1) := (x(n)*a + c) mod m

eg. the early Random Number generator used for the 41c used
c=.211327, a=9821, m=1. (This is from memory, but I think I'm right ;-)
Now, the algorithm on the 48 uses c=0, and thus can never return 0.
