WR REDRAW ( area ) 
Parameter Type   Description
area  Longint in 4D Write area

The WR REDRAW command causes area to be redrawn. This command is useful when you have disabled screen updating with the WR UPDATE MODE command and now want to redraw a 4D Write area to show how previously executed code has modified the area.

Example  

The following example turns off screen updates, calls the Reformat project method that reformats area, and then redraws area without turning screen updating back on.

 WR UPDATE MODE(area;0)
  `Turn off screen updating
 Reformat(area)
  `area can be passed to a method
 WR REDRAW(area)
  `Redraw to display changes
