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

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