-- OBJECTIVE:
--     CHECK THAT READ (WITH AND WITHOUT PARAMETER FROM), WRITE (WITH

--     END_OF_FILE ARE SUPPORTED FOR DIRECT FILES WITH ELEMENT_TYPE
--     PRIVATE.
 
-- APPLICABILITY CRITERIA:
--
--     THIS TEST IS ONLY APPLICABLE TO IMPLEMENTATIONS WHICH SUPPORT
--     CREATION WITH INOUT_FILE MODE AND OPENING WITH IN_FILE MODE FOR
--     DIRECT FILES.
 
-- HISTORY:
--     ABW 08/18/82
--     SPS 09/15/82
--     SPS 11/09/82
--     JBG 02/22/84  CHANGE TO .ADA TEST
--     EG  11/19/85  CORRECT SO TEST CAN HANDLE IMPLEMENTATION WITH
--                   POSITIVE_COUNT'LAST=1; COVER POSSIBILITY OF CREATE
--                   RAISING USE_ERROR; ENSURE RESET DOESN'T RAISE
--                   EXCEPTION IF CREATE FAILS; CHECK THAT WE CAN READ
--                   DATA THAT HAS BEEN WRITTEN.
--     TBN 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     DWC 08/11/87  ISOLATED EXCEPTIONS.
