DISPEND()
 Display buffered screen updates
------------------------------------------------------------------------------
 Syntax

     DISPEND() --> NIL

 Returns

     DISPEND() always returns NIL.

 Description

     DISPEND() is a screen function that informs the CA-Clipper display
     output system that the application has finished performing a series of
     display operations.

     DISPEND() is used in concert with DISPBEGIN() so the display output
     system can buffer display updates.  This can be important for
     applications in which complex screen displays are slow and the
     appearance of performance is desired.

     For more information, refer to DISPBEGIN()

 Examples

     .  This example buffers screen output, updates the screen, then
        displays the buffered screen output:

        DISPBEGIN()            // Start screen buffering
        //
        SETPOS(10, 10)
        DISPOUT("A display update")
        SETPOS(11, 10)
        DISPOUT("Another display update")
        //
        DISPEND()              // Display buffered screen data
