What characterizes session variables compared to environment variables?

Session variables are characterized by their writable nature. This means that during the execution of a process, session variables can be modified at runtime. They are specifically designed to hold data that is used for the duration of a session, and users can update these values as needed throughout the workflow. This flexibility allows for dynamic data handling, which is crucial for process automation.

In contrast to session variables, environment variables are static and typically set at the beginning of the environment; they are designed to hold configuration data that remains consistent across multiple sessions. Since session variables exist only within the scope of a running session, they cannot be shared across instances or accessed once that session has ended, which distinguishes their functionality from environment variables.

Understanding the writable nature of session variables is essential for automation developers, as it influences how data is manipulated and maintained throughout the execution of a process in Blue Prism.
