VMS Help CMS, MODIFY, ELEMENT, Qualifiers, /NOTES="string"  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Establishes the notes attribute for the element. If an element
    has a notes attribute, notes are appended to the lines of the file
    when it is retrieved by the FETCH or RESERVE command.

    The quoted string specifies the format of the note. The quoted
    string can contain text or the characters #G (or #g), or both.
