VMS Help LICENSE, MODIFY, Qualifiers, /COMMENT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /COMMENT=string

    Specifies a string of text. Use this comment field of up to 63
    characters to associate information for this transaction with
    the license. History records for the license retain this license
    information. If you specify more than one word, enclose the text
    in quotation marks (""). This qualifier is optional.

    The text in the comment field is replaced only when you enter new
    comments with another LICENSE MODIFY command. At this point the
    old comment text is available as a history record.
