- If a value has already been associated with a key, AskedValue returns that value just like Ask. But unlike Ask, AskedValue will never request a value from the user, instead returning Missing[…] if no value has yet been provided.
- When no value is yet known for the requested key, AskedValue["key"] returns Missing["NotAsked","key"].
