-- OBJECTIVE:
--     CHECK THAT NEW_PAGE OUTPUTS A LINE TERMINATOR FOLLOWED BY A PAGE

--     OUTPUTS A PAGE TERMINATOR ONLY.

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

-- HISTORY:
--     ABW 09/02/82
--     JBG 01/18/83
--     TBN 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     DWC 09/23/87  ADDED A CASE WHICH CALLS NEW_LINE AND NEW_PAGE
--                   CONSECUTIVELY AND SEPARATED CASES INTO DIFFERENT
--                   IF STATEMENTS.  ADDED CHECK FOR USE_ERROR ON
--                   DELETE.
