Display buffered screen updates


      DispEnd() --> NIL


DispEnd() always returns NIL.


DispEnd() is a screen function that informs the Harbour display output system that the application has finished performing a series of display operations.

DispEnd() is used 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.


      .  This example buffers screen output, updates the screen, and
      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


DispBegin(), DispCount()
