 display-id

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

    Specifies the virtual display in which to move the virtual
    cursor. The display-id argument is the address of an unsigned
    longword that contains the display identifier.

    The display identifier is returned by SMG$CREATE_VIRTUAL_DISPLAY.

 delta-row

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by reference

    Specifies the number of rows to move the virtual cursor. The
    delta-row argument is the address of a signed longword that
    contains the number of rows to move. If omitted, the virtual
    cursor remains at the current row position. If delta-row is
    positive, the virtual cursor moves downward the specified number
    of rows. If delta-row is negative, the virtual cursor moves
    upward the specified number of rows.

 delta-column

    OpenVMS usage:longword_signed
    type:         longword (signed)
    access:       read only
    mechanism:    by reference

    Specifies the number of columns to move the cursor. The delta-
    column argument is the address of a signed longword that contains
    the number of columns to move. If omitted, the virtual cursor
    remains at the current column position. If delta-column is
    positive, the virtual cursor moves the specified number of
    columns to the right. If delta-column is negative, the virtual
    cursor moves the specified number of columns to the left.
