I'm not sure if I understand what you mean. If a user starts a session and writes a value to a variable, how does the computer know whether the value should be temporary or permanent after the user ends the session?

Same as with variable scope in the language. Every variable is persistent until deleted or released. Such a language would need to manifest transactions (or some other behavior for consistency), but much of it would be handled with existing language concepts.
