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

       /COPY(default)
       /NOCOPY

    Specifies whether you want the product material files and
    associated directories included in the product kit. The /NOCOPY
    qualifier can save file processing time when you are debugging a
    PDF file and do not need to produce a complete product kit.

    The use of /NOCOPY with /FORMAT=SEQUENTIAL is not supported and
    produces undefined results.
