Screens have Output Parameters.

In OutSystems, screens do not have output parameters. The ability to pass data from a screen typically uses an input parameter when navigating to that screen, but output parameters, as seen in other components like actions or blocks, are not applicable for screens.

This distinction is important for understanding how data flows within an OutSystems application. While you might be able to pass values into a screen through input parameters, screens are not designed to return values or output parameters after they have been displayed. This helps maintain a clear separation between the user interface (screens) and data handling functions (actions, entities) in the OutSystems framework.

By grasping this concept, you will improve your ability to design effective data flows within your applications and set up frameworks for communication between different components of your application.
