-- OBJECTIVE:
--     CHECK THAT EQUALITY AND INEQUALITY ARE EVALUATED CORRECTLY FOR
--     RECORD OBJECTS HAVING DIFFERENT VALUES OF THE 'CONSTRAINED
--     ATTRIBUTE.

-- HISTORY:
--     TBN  08/07/86  CREATED ORIGINAL TEST.
--     VCL  10/27/87  MODIFIED THIS HEADER; RELOCATED THE CALL TO
--                    REPORT.TEST SO THAT IT COMES BEFORE ANY
--                    DECLARATIONS; CHANGED THE 'ELSEIF' CONDITION IN
--                    THE PROCEDURE 'PROC' SO THAT IT REFERS TO THE
--                    FORMAL PARAMETERS.
