--     CHECK THAT CLOSING A FILE HAS THE FOLLOWING EFFECT:
--          1) IF THERE IS NO LINE TERMINATOR, A LINE TERMINATOR, PAGE
--             TERMINATOR, AND FILE TERMINATOR ARE WRITTEN AT THE END
--             OF THE FILE.
--          2) IF THERE IS A LINE TERMINATOR BUT NO PAGE TERMINATOR, A
--             PAGE TERMINATOR AND A FILE TERMINATOR ARE WRITTEN.
--          3) IF THERE IS A PAGE TERMINATOR, A FILE TERMINATOR IS
--             WRITTEN.

-- APPLICABILITY CRITERIA:
--     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH SUPPORT
