--
-- OBJECTIVE:
-- Check that Constraint_Error is raised in cases of null arrays when:
-- 1. an assignment is made to a null array if the length of each
-- dimension of the operand does not match the length of
-- the corresponding dimension of the target subtype.
-- 2. an array actual parameter does not match the length of
-- corresponding dimensions of the formal in out parameter where
-- the actual parameter has the form of a type conversion.
-- 3. an array actual parameter does not match the length of
-- corresponding dimensions of the formal out parameter where
-- the actual parameter has the form of a type conversion.
--
-- TEST DESCRIPTION:
-- This transition test creates examples where array of null ranges
-- raises Constraint_Error if any of the lengths mismatch.
--
-- Inspired by C52103S.ADA, C64105E.ADA, and C64105F.ADA.
--
--
-- CHANGE HISTORY:
-- 21 Mar 96 SAIC Initial version for ACVC 2.1.
-- 21 Sep 96 SAIC ACVC 2.1: Added new case.
