in thread scope of variable

Nested subs in Perl are actually global, but they bind, as a closure to the variables for the first time the parent sub is called.

Which is, I'm pretty sure, the root of his problem.

    Thanks, I learn something new about Perl every day. When I saw the nested subs, I thought I was looking a JavaScript for a moment! :-)

    If you spot any bugs in my solutions, it's because I've deliberately left them in as an exercise for the reader! :-)
