VMS Help PRODUCT, FIND, Qualifiers, /SPAN_VERSIONS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /SPAN_VERSIONS=keyword([,...])

    Selects software products whose versions match the specified
    version criteria. The keywords are:

    ABOVE=version    Selects versions greater than the version
                     specified

    BELOW=version    Selects versions less than the version specified

    MINIMUM=version  Selects versions greater than or equal to the
                     version specified

    MAXIMUM=version  Selects versions less than or equal to the
                     version specified

    The ABOVE, BELOW, MINIMUM, and MAXIMUM keywords
    can be used alone or in combination. For example,
    /SPAN_VERSIONS=(MINIMUM=V2.1,BELOW=V3.0) selects versions greater
    than or equal to V2.1 and less than (but not including) V3.0.
    Using the MAXIMUM keyword instead of BELOW would select versions
    that include V3.0.
