       /NOHEADING

    Includes file names in the output file and displays a line of
    30 asterisks(*)  as a window separator between groups of lines
    that belong to different files. With the default heading format,
    file names are printed only when more than one file is specified
    or when the asterisk (*)  and the percent sign (%) wildcard
    characters are used.

    The /WINDOW qualifier displays a line of 15 asterisks to separate
    each window within a file.
