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

       /DESTINATION=device-name:[directory-name]

    Specifies a location where the utility will place a copy of a
    sequential kit; for a reference kit, specifies the top-level
    directory location where the utility will place files. If the
    device name is not provided, it defaults to the user's default
    device. If the directory name is omitted, it defaults to the
    user's default directory.

    The PRODUCT COPY operation ignores the PCSI$DESTINATION logical
    name whether or not you use the /DESTINATION qualifier.
