    How do I tell the compiler that the signals/ports reffered to in the
    procedures within a package are declared outside the package ?

    Signals can only be driven by a process.

    A packaged procedure is called from a process
    and has signal identifiers passed to it.

    A procedure declared in process scope
    has direct access.
