The getUserData(...) function is used to store and retrieve information in a user's account preferences or in the current session. Only the data added by formula can be retrieved or stored by formula. In other words, this will not allow access to any session or user data stored and used by the BlueStep platform software. Only String data may be stored. String values are stored by name. Multiple values can be stored under the same name in a list. Special functions are provided to allow each list of Strings to be used as a stack, queue or standard list. Special functions are also provided for storing and retrieving a single value when a list is not needed.
