 title-text

    Specifies the text of one title line. The text must be enclosed
    in quotation marks, and cannot be longer than the current
    terminal width. In a list of title-text parameters, the first
    title-text parameter specifies the text for the first title line,
    the second parameter specifies the text for the second title
    line, and so on. If you use the /LINE=n qualifier, the first
    title-text parameter specifies the text for line n, the second
    parameter specifies the text for line n+1, and so forth. You can
    specify up to six lines of title text.
