Although I did not read the original post, I thought I may be able to
assist Mr. Dunton with an easy program to find the nth Finonacci number.
Pat Mara showed an intuitive recursive method- so I shall address a
NONrecursive method.  There is the program I quickly wrote on my TI-81.

(1+5^(1/2))/2->A
(1-5^(1/2))/2->B
Disp "Fib Num?"
Input N
(1/5^(1/2))(A^N-B^N)->X
Disp X

The output is the Nth Fibonacci number.
