The a!save() function allows you to perform which of the following operations?

The a!save() function is designed specifically for updating values in the context of Appian's interfaces and processes. Its primary role is to facilitate the saving of a new value to a rule input or a local variable when a specific action occurs, such as a user interaction.

When using a!save(), it allows the developer to define how input values should be altered in response to interface events — for example, changing the content of a local variable based on user input from a form. This enables dynamic and responsive user interfaces, allowing for immediate reflection of changes as users interact with the application.

Other options, such as sending notifications, deleting records, or storing user preferences, do not align with the functionality of a!save(). Sending notifications and deleting records are managed through different functions or process models, while user preferences might require separate handling that is beyond the scope of just preserving a value in variables or inputs. Thus, the primary function of a!save() is appropriately centered around updating values in response to interactions, confirming that updating a rule input or a local variable is the correct operation associated with this function.
