-- HISTORY:

--     DAT 08/20/81  CREATED ORIGINAL TEST.

--     SPS 05/03/82

--     BCB 08/04/88  MODIFIED HEADER FORMAT AND ADDED CHECKS FOR OTHER

--                   OPERATIONS OF A DISCRETE TYPE.

--     RJW 03/27/90  REVISED TEST TO CHECK FOR A GENERIC FORMAL

--                   DISCRETE TYPE.

--     CJJ 10/14/90  ADDED CHECKS FOR RELATIONAL OPERATOR (<, <=, >, >=);

--                   MADE FAILED MESSAGES IN PROCEDURE BODY MORE SPECIFIC.
