-- OBJECTIVE:
--     CHECK THAT USE_ERROR IS RAISED BY A CALL TO SET_LINE_LENGTH
--     OR TO SET_PAGE_LENGTH WHEN THE SPECIFIED VALUE IS INAPPROPRIATE
--     FOR THE EXTERNAL FILE.

-- APPLICABILITY CRITERIA:
--     THIS TEST IS APPLICABLE TO IMPLEMENTATIONS THAT SATISFY THE
--     FOLLOWING CONDITIONS:
--       1) TEXT FILES ARE SUPPORTED
--       2) EITHER BY DEFAULT OR BY USE OF THE "FORM" PARAMETER TO
--          THE CREATE PROCEDURE, A TEXT FILE CAN BE CREATED FOR
--          WHICH AT LEAST ONE OF THE FOLLOWING CONDITIONS HOLDS:
--           A)  THERE IS A VALUE OF TYPE TEXT_IO.COUNT THAT IS NOT
--               AN APPROPRIATE LINE-LENGTH FOR THE FILE,
--             OR
--           B)  THERE IS A VALUE OF TYPE TEXT_IO.COUNT THAT IS NOT
--               AN APPROPRIATE PAGE-LENGTH FOR THE FILE.

-- MACRO SUBSTITUTIONS:
--     FOR THE MACRO SYMBOL "$FORM_STRING," SUBSTITUTE A STRING LITERAL
--     SPECIFIYING THAT THE EXTERNAL FILE MEETS BOTH OF THE CONDITIONS
--     (A) AND (B) ABOVE.  IF IT IS NOT POSSIBLE TO SATISFY BOTH
--     CONDITIONS, THEN SUBSTITUTE A STRING LITERAL SPECIFYING THAT THE
--     EXTERNAL FILE SATISFIES ONE OF THE CONDITIONS.  IF IT IS NOT
--     POSSIBLE TO SATISFY EITHER CONDITION, THEN SUBSTITUE THE NULL
--     STRING ("").
--     FOR THE MACRO SYMBOL "$INAPPROPRIATE_LINE_LENGTH," SUBSTITUTE
--     A LITERAL OF TYPE COUNT THAT IS INAPPROPRIATE AS THE LINE-LENGTH
--     FOR THE EXTERNAL FILE.  IF THERE IS NO SUCH VALUE, THEN USE -1.
--     FOR THE MACRO SYMBOL "$INAPPROPRIATE_PAGE_LENGTH," SUBSTITUTE
--     A LITERAL OF TYPE COUNT THAT IS INAPPROPRIATE AS THE PAGE-LENGTH
--     FOR THE EXTERNAL FILE.  IF THERE IS NO SUCH VALUE, THEN USE -1.
