Local $oDict_A = ObjCreate( "Scripting.Dictionary" ) to make copy of $oDict_A object we do: > Local $oDict_B = $oDict_A > or can use Ptr($oDict_A) to make copy $oDict_A object. Now Ptr($oDict_A) method work fine if used within same script.

I asked ChatGPT, and it didn't dismiss my idea as irrelevant or accuse me of moving the goal posts. When people don’t have an answer to a question, they often resort to insults or try to belittle others to appear more knowledgeable. In any case, the answer to the original post is CoMarshalInterface and CoUnmarshalInterface.
