-- OBJECTIVE:
--     CHECK THAT FIXED_IO PUT RAISES LAYOUT_ERROR WHEN THE NUMBER OF
--     CHARACTERS TO BE OUTPUT EXCEEDS THE MAXIMUM LINE LENGTH.  CHECK
--     THAT IT IS NOT RAISED, BUT RATHER NEW_LINE IS CALLED, WHEN THE
--     NUMBER DOES NOT EXCEED THE MAX, BUT WHEN ADDED TO THE CURRENT
--     COLUMN NUMBER, THE TOTAL EXCEEDS THE MAX.

--     THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS WHICH SUPPORT
--     TEXT FILES.

-- HISTORY:
--     JLH 09/15/87  CREATED ORIGINAL TEST.
