Thanks nick. That's about where I'm at as well. I didn't know which param to use so I ran reg edit and looked in HKEY_CLASSES_ROOT and found Agent.Control.2 along with some variations. I do believe this is the one that is supposed to be used. I don't know what to do now though. When try to load merlin it tells me that characters is not an object. This leads me to believe that I need to instantiate another object and add it to my agent object. And then use the load method of that object. WDYT?
