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 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.
Examples
. 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
Files Library is CLIPPER.LIB.
