What is a 'context variable' in OutSystems?

A context variable in OutSystems is designed to store data that is relevant to a specific screen or action context. By using context variables, developers can make decisions and manage the flow of data that is pertinent only to the particular screen or action being executed, enhancing the overall user experience and making the application more dynamic.

Context variables help to create a distinct environment for the data that is needed at runtime, allowing for data to be passed around as necessary within that specific scope without affecting other parts of the application. This localized approach provides greater flexibility and can optimize performance, as it reduces the amount of unnecessary data handling across different areas of the application.

The other options do not accurately describe context variables. A static value unrelated to actions, for instance, would suggest a lack of dynamism and relevance, while a global variable would imply accessibility throughout all applications instead of being limited to a specific context. A placeholder for user feedback does not pertain to data management in the same way that context variables do.
