The input/output mask of a screen contains all of the normal graphical user interface elements, such as input/output fields, pushbuttons, and radio buttons. Basically it contains all the information regarding the screen field.
When the screen mask is displayed by the SAPgui, two events are triggered: Before the screen is displayed, the Process Before Output (PBO) event is processed. When the user interacts with the screen, the Process After Input (PAI) event is processed.
Bottom line is...
Screens send data to, receive data from, and react to the user’s interaction with the input mask.
