Remarks
Use the PushScreen Method to save a current screen file to device memory.
Use the RestoreScreen Method if you wish to restore a screen without deleting it from the device memory.
When used in conjunction, PushScreen and PullScreen or RestoreScreen can temporarily interrupt a displayed screen within your application, then restore the screen to its original state. This creates faster display when re-using screens.
