Unformatted text preview: present, then the entire formal is considered to be associated with the entire actual. Similarly, for the association of actuals with corresponding formal subprogram parameters, association of a formal parameter of a given composite type with an actual of the same type is equivalent to the association of each scalar subelement of the formal parameter with the matching subelement of the actual. Different parameter passing mechanisms may be required in each case, but in both cases the associations will have an equivalent effect. This equivalence applies provided that no actual is accessible by more than one path (see 220.127.116.11). A formal may must46 be either an explicitly declared interface object or member (see Section Clause47 3) of such an interface object. In the former case, such a formal is said to be associated in whole. In the latter cases, named association must be used to associate the formal and actual; the subelements of such a formal are said to be associated individually. Furthermore, every scalar subelement of the ex...
