--     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.
