in reply to subroutine memory variable scope

You don't seem to be using @the_inputs for anything useful, and you throw away the returned value, at least in the internal recursive calls.

Iterating over the inputs for a given recursion will take care of itself - I don't see a need to save the list for posterity.
I would suggest getting rid of it entirely, since you have shown no use for it.

    Maybe I'm not understanding. I need the @the_inputs to be returned from the subfunction - I will be using it in a later call to verify if the user supplied inputs are valid ones.
