[Closed] How much is scriptable in particle flow?

I have heard that not everything is scriptable in PFlow, is that really right?

I mean, if I start a new scene, choose maxscrip listener and turn on macrorecording and then start to build my system, with a new empty flow, some operators, create a new event and put on some new operators and in there I connect the new event with the one before, make some changes to the operators and so on… Everything seems to be scripted, at least what I did…
After that, I copy/paste what was recorded into a new emty script and reset max and run that script, after that everything setups right the way it was before.

So, my question is, what is NOT scriptable in particle flow and 3ds max 8-9?

Need to know that, thanks for any reply for those who knows…
