25 -- OBJECTIVE:
26 -- CHECK THAT READ RAISES END_ERROR WHEN THE CURRENT READ POSITION
27 -- IS GREATER THAN THE END POSITION. ALSO CHECK THAT END_OF_FILE
28 -- CORRECTLY DETECTS THE END OF A DIRECT FILE.
30 -- APPLICABILITY CRITERIA:
31 -- THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH SUPPORT
32 -- CREATION WITH INOUT_FILE MODE AND OPENING OF IN_FILE MODE.
34 -- HISTORY:
35 -- SPS 09/28/82
36 -- JBG 02/22/84 CHANGE TO .ADA TEST
37 -- EG 05/16/85
38 -- GMT 08/03/87 ADDED CODE TO CHECK THAT END_OF_FILE WORKS, AND
39 -- ADDED CODE TO PREVENT SOME EXCEPTION PROPAGATION.
