static link
     
         (Or "access link" or "environment link") A pointer
        from an {activation record} to the activation record for the
        textually enclosing {scope}.  A static link is only required
        in a statically (lexically) scoped language.
     
        The number of static links to follow may be determined
        statically (at compile time).  It is simply the difference in
        {lexical nesting depth} between the declaration and the
        reference.
     
        See also {display}.
