I have tried a couple of ways to iterate over the lua table f in the most

You have a *global* table f that collides with the internals of context

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

\startluacode
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
return fibs[n]
end
context.bTABLE()

Hi Gerben,
I think you are using mkii, while the code sent by Hans and containing
\doifcheckedpagestate
is intended for use with mkiv.

I’ve tried to add this to my environment and product file, but even without
using it, it ends in an error:
