-- L IS A FUNCTION CALL DELIVERING A RECORD VALUE SUCH THAT,
-- FOR THE EXISTING DISCRIMINANT VALUES, THE COMPONENT
-- DENOTED BY R DOES NOT EXIST.
-- L IS AN ACCESS OBJECT AND THE OBJECT DESIGNATED BY THE ACCESS
-- VALUE IS SUCH THAT COMPONENT R DOES NOT EXIST FOR THE
-- OBJECT'S CURRENT DISCRIMINANT VALUES.
-- L IS A FUNCTION CALL RETURNING AN ACCESS VALUE AND THE OBJECT
-- DESIGNATED BY THE ACCESS VALUE IS SUCH THAT COMPONENT R
-- DOES NOT EXIST FOR THE OBJECT'S CURRENT DISCRIMINANT
-- VALUES.
-- HISTORY:
-- TBN 05/23/86 CREATED ORIGINAL TEST.
