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

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

    Specifies the location where the utility is to place the
    extracted product description file (PDF). If the device name
    is not provided, the default is the user's default device. If
    the directory name is omitted, or the /DESTINATION= qualifier is
    not specified, the default is the user's default directory. The
    EXTRACT PDF operation ignores the PCSI$DESTINATION logical name
    whether or not you use the /DESTINATION qualifier.
