Is there a action that can instantly convert actionsctipt 2 to actionscript 3?

I know a lot about actionscript 2. But know little about actionscript 3. Is there a command I can use to instantly turn actionscript 2 to 3?Is there a action that can instantly convert actionsctipt 2 to actionscript 3?
No. There are some commands that are the same (like ';stop();'; for example), but for the parts that are different there is no action to instantly convert AS2 to AS3.
