Check that objects +-- of the above types do not need explicit constraints if they have +-- initial values. +-- +-- TEST DESCRIPTION: +-- An indefinite subtype is either: +-- a) An unconstrained array subtype. +-- b) A subtype with unknown discriminants. +-- c) A subtype with unconstrained discriminants without defaults. +-- +-- Declare several indefinite types in a parent package specification. +-- In the private part, complete one type with a discriminant without +-- default (indefinite) and the other with a default discriminant +-- (definite). Declare objects of both indefinite and definite subtypes +-- in children (private and public) with initialization expressions. The +-- test verifies all values of the objects. It also verifies that +-- Constraint_Error is raised if an attempt is made to change the +-- discriminants of the objects of the indefinite subtypes. +-- +-- +-- CHANGE HISTORY: +-- 15 Jan 95 SAIC Initial version for ACVC 2.1 +-- 25 Jul 96 SAIC Modified test description.
