What defines the scope of local variables in OutSystems?

Local variables in OutSystems are defined with a scope that is specific to the screen or function where they are created. This means they can only be accessed and utilized within that particular context. When a variable is declared as local, it is not visible or accessible outside of its defining screen or block, which helps maintain encapsulation and prevents unintended interactions with other parts of the application.

This encapsulation enables developers to manage data that is specific to a user interface element or a specific logic flow without affecting or being affected by other components or screens in the application. It is a fundamental concept in programming that promotes better organization and reduces the likelihood of errors stemming from variable conflicts.

In contrast, other choices suggest broader accessibility, which local variables do not possess. For instance, the premise that local variables can be used across multiple screens or have global access is inaccurate, as it goes against the principle of local scoping that is essential to good software design. The notion that they can only be used within server actions also misconstrues their definition as they are typically utilized within client-side screen logic.
