Is it possible to logically split the code into several separate scripts and call the function of one script from another?

I agree with @xkkmEl and even stated you not need to move the code to another script, and that you need a programmatic reason, but this is a great reason, a test to learn how it works with papyrus .. do it!! there nothing wrong with learning and experimenting
