This function looks up a pre-configured translation text. It is used internally by the DataHub interface programmer to specify which text strings in the interface should be translated when the user selects a language in the Properties window of the DataHub instance. Language selection itself cannot be done within the Gamma engine; it can only be done through the Properties window.
If your language is not available in the DataHub program, you can contact Cogent for instructions on how to add a translation to the Cogent DataHub source code.
