-- OBJECTIVE:
--     WHEN THE TYPE MARK IN A QUALIFIED EXPRESSION DENOTES A
--     CONSTRAINED ACCESS TYPE, CHECK THAT CONSTRAINT_ERROR IS RAISED
--     WHEN THE VALUE OF THE OPERAND IS NOT NULL AND THE DESIGNATED
--     OBJECT HAS INDEX BOUNDS OR DISCRIMINANT VALUES THAT DO NOT EQUAL
--     THOSE SPECIFIED IN THE ACCESS TYPE'S CONSTRAINT.
 
-- HISTORY:
--     RJW 7/23/86
--     DWC 07/24/87  REVISED TO MAKE THE ACCESS TYPE UNCONSTRAINED
--                   AND TO PREVENT DEAD VARIABLE OPTIMIZATION.
