You have a *global* table f that collides with the internals of context ... local function fib(n) local f={1,1} ...

This version recomputes all fibnocci numbers from scrach each time. Here is a memoized version:

local fibs = {1, 1} local function fib(n) if fibs[n] == nil then print(">>>>", "Computing fib:" .. n) fibs[n] = fib(n-1) + fib(n-2) end ...

Thanks to you both! I missed the global/local conflict, and then learned a way to avoid double computation; thanks again! John
