"Fibonacci Sequence" by Rosetta Code

The Room is a room.

To decide which number is the fibonacci of (n - a number):
	if n is 0, decide on 0;
	if n is 1, decide on 1;
	decide on (fibonacci of (n - 1)) + (fibonacci of (n - 2)).

When play begins:
	repeat with N running from 0 to 10:
		say "fib([N]) = [fibonacci of N][line break]";
	end the story.
