UPDATE

    Causes the screen manager to make a window reflect the current state of
    the buffer that is mapped to the window.  The screen manager updates
    windows after each keystroke.  This means that if a key is bound to a
    procedure, several built-ins may be executed before the screen actually
    reflects the internal state of the buffer.  If you want the screen to
    reflect changes before the entire procedure is executed, you can force
    an immediate update by adding an UPDATE statement to the procedure.

 Syntax

    UPDATE ({window | ALL})
 Parameters

    window               The window that you want updated.  The window must
                         be visible for the update to occur.

    ALL                  Specifies that all visible windows are to be
                         updated to reflect the current state of the
                         buffers mapped to them.

 Example

    UPDATE (new_window);

    This statement causes the screen manager to make the new window reflect
    the current internal state of the buffer associated with that window.
