-- OBJECTIVE:
--     CHECK THAT THE PREFIX OF THE 'POSITION, 'LAST_BIT, AND 'FIRST_BIT
--     ATTRIBUTES CAN DENOTE A RECORD COMPONENT, AND THE ATTRIBUTES
--     RETURN APPROPRIATE VALUES WHEN A RECORD REPRESENTATION CLAUSE IS
--     NOT PRESENT.

-- HISTORY:
--     BCB 09/14/87  CREATED ORIGINAL TEST.
--     RJW 02/08/88  REVISED SO THAT TEST PASSES IF BOOLEAN'SIZE = 1.
--     RJW 05/31/90  CORRECTED COMPARISONS INVOLVING SIZES.
--     LDC 10/04/90  ADDED CHECK FOR 'POSITION.
