-- OBJECTIVE:

--     CHECK THAT, FOR DIRECT_IO, WRITE RAISES THE EXCEPTION

--     USE_ERROR IF THE CAPACITY OF THE EXTERNAL FILE IS EXCEEDED.

--     THIS TEST ONLY CHECKS THAT THE IMPLEMENTATION SUPPORTS AN

--     EXTERNAL FILE CAPACITY OF 4096 CHARACTERS OR LESS.

-- APPLICABILITY CRITERIA:

--     THIS TEST IS ONLY APPLICABLE TO IMPLEMENTATIONS WHICH SUPPORT

--     DIRECT FILES.  ALSO, THE IMPLEMENTATION MUST BE ABLE TO

--     RESTRICT THE CAPACITY OF AN EXTERNAL FILE.

--     $FORM_STRING2 IS DEFINED SUCH THAT THE CAPACITY OF THE FILE IS

--     RESTRICTED TO 4096 CHARACTERS OR LESS. IF THE IMPLEMENTATION

--     CANNOT RESTRICT FILE CAPACITY, $FORM_STRING2 SHOULD EQUAL

--     "CANNOT_RESTRICT_FILE_CAPACITY".

-- HISTORY:

--     JLH 07/12/88  CREATED ORIGINAL TEST.

-- PWN 11/30/94 SUBTYPE QUALIFIED LITERALS FOR ADA 9X.
