Dear Hans,
I tested your code.

…

> document.MakeFooter()
> end
This part produces the right logical value.
But, the next part doesn’t produce the correct value.
While the value of each variable is printed correctly,
the values of outputs are all 0.

I think that the logical function “document.logicF()"is not working for the
array tf={“1”,”0”}.
In python, 1 and 0 are treated as true and false. But, I read that only “false”
and “nil” are treated as false in Lua, that is, “0” is also treated as true!
I checked it using the following simple code:
\starttext
\startluacode
if 0 then context("True")
else context("False")
end
\stopluacode
\stoptext
The output
The output is “True”.
Best regards,
Dalyoung
