pasteboard-id
    OpenVMS usage:identifier
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    Specifies the pasteboard whose characteristics are to be changed
    or retrieved. The pasteboard-id argument is the address of an
    unsigned longword that contains the pasteboard identifier.
    The pasteboard identifier is returned by SMG$CREATE_PASTEBOARD.
