pasteboard-id

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

    Specifies the pasteboard to be changed. 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.

 new-mode

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

    Specifies the new control settings to be used. The optional
    new-mode argument is the address of an unsigned longword that
    contains the mode settings. A bit set to 1 forces that mode to be
    employed; a bit set to 0 inhibits that mode of operation.

    Valid settings are as follows:

    SMG$M_BUF_ENABLED  Enables buffering.
    SMG$M_CLEAR_       Causes the Screen Management Facility to clear
    SCREEN             the screen when the program exits if you have
                       not previously deleted the pasteboard.
    SMG$M_IGNORE       Allows you to delete the pasteboard even if
                       batching is in effect.
    SMG$M_MINUPD       Enables minimal update (the default).
    SMG$M_NOTABS       Causes the Screen Management Facility not to
                       use tab characters to format the screen.
    SMG$M_PROTECT      Protect pasteboard operations from AST
                       interrupts (the default).
    SMG$M_RELEASE_PBD  Allows you to change the pasteboard size
                       (using the SMG$CHANGE_PBD_CHARACTERISTICS
                       routine) and prevents the Screen Management
                       Facility from modifying anything on the screen
                       outside of the smaller pasteboard.

    All other bits must be 0 and are reserved for future use by
    Compaq.

 old-mode

    OpenVMS usage:mask_longword
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference

    Receives the control settings that were in effect before calling
    this procedure. The optional old-mode argument is the address
    of an unsigned longword into which the former mode settings are
    written. A bit set to 1 indicates that the specified mode was
    employed; a bit set to 0 indicates that the mode was inhibited.

 buffer-size

    OpenVMS usage:word_unsigned
    type:         word (unsigned)
    access:       read only
    mechanism:    by reference

    Specifies the size of the buffer in bytes. The optional buffer-
    size argument is the address of an unsigned word that contains
    the size of the buffer. The buffer-size argument is used when
    buffering mode is enabled (SMG$M_BUF_ENABLED). The default and
    minimum buffer size is 256 bytes. The maximum value is 65535. The
    buffer-size value depends on user authorization file (UAF) values
    and is maximized with the SYSGEN parameter MAXBUF.
