-- 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.
