Yep. You can get away with accessing those lexicals in a function when
your "main" code is at the top level in the script. But when you have
the variable declarations inside one function, the other function can't
see them.
I would do away with main, moving the code out into the top level. If
you *really* have your heart set on your main function (why???), you
could move just the declarations of the "global" variables outside of
it.
