-- 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.
