--     SEQUENTIAL FILES WITH ELEMENT_TYPE CONSTRAINED RECORD TYPES.

-- HISTORY:
--     ABW 08/17/82
--     SPS 09/15/82
--     SPS 11/09/82
--     JBG 05/02/83

--     TBN 11/04/86  REVISED TEST TO OUTPUT A NOT_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     JLH 07/28/87  REMOVED THE DEPENDENCE OF RESET BEING SUPPORTED
--                   AND CREATED EXTERNAL FILES RATHER THAN TEMPORARY
