-- 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.
