• Change the split screen mode to full screen mode without restoring it back to the
input setting.
B_CALL ForceFullScreen
Note: The B_CALL routine was not used in the first option above so that the graph would not be
marked dirty. If the split screen mode is not temporarily changed, the graph needs to be
marked as dirty so it will reflect the new screen size. Example one restores the input setting,
so no regraph is necessary. It is entirely up to the application if causing the regraph is a
concern or not.
