-- OBJECTIVE:
--     CHECK THAT SKIP_LINE INCREMENTS THE CURRENT LINE NUMBER BY ONE
--     AND SETS THE CURRENT COLUMN NUMBER TO ONE IF THE LINE TERMINATOR
--     IS NOT FOLLOWED BY A PAGE TERMINATOR, AND THAT IT SETS BOTH THE

--     NUMBER BY ONE IF THE LINE TERMINATOR IS FOLLOWED BY A PAGE
--     TERMINATOR.

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

--     TBN 11/04/86  REVISED TEST TO OUTPUT A NON_APPLICABLE
--                   RESULT WHEN FILES ARE NOT SUPPORTED.
--     DWC 09/09/87  REVISED TEST TO USE A FILE NAME, REMOVED
--                   DEPENDENCE ON RESET, AND ATTEMPTED TO
