Returns (first syntax line) or specifies (second syntax line) whether the screen display is cleared when the number of screen columns is changed. The number of screen columns can be specified using either the DisplayColumns property or the Screen tab in the Display Setup dialog box.
In this example, the screen display will be cleared when the change to the DisplayColumns property is executed:
Session.WidthChangeClear = True
Session.DisplayColumns = 132
The default value is True. The value is automatically changed to False if you select a WYSE terminal type using the Reflection Terminal Setup dialog box.
