If the object results in "userdata" when printed, it's most likely a PDK 
Framework class (starting with the FC prefix). In this case, it's the 
FCString class.

To access the documentation for that class, press the "Class Browser" 
button on the "Development" tab in JW Lua. In the list of classes in the 
Class Browser, select "FCString" and then press the "Class Documentation".

Hint: the method you're searching starts with "To". :-)
