 pasteboard-id

    OpenVMS usage:identifier
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    Specifies the pasteboard from which to retrieve the character.
    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.
