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

    Specifies the top-level directory where the product to be
    registered resides. If you omit the device name, the utility uses
    your current default device. If you omit the directory name, the
    utility uses [VMS$COMMON] as the default directory.

    If you do not use this qualifier to specify a destination,
    the utility uses the location defined by logical name
    PCSI$DESTINATION. If this logical name is not defined, the
    utility registers the software in SYS$SYSDEVICE:[VMS$COMMON], the
    default top-level directory for software product files.
