Thank you for your helpful suggestion to this unworthy novice. Yes, I am dumb. I humbly apologise for not having yet attained enlightenment such as your Exalted Greatness has.

I have spent a day reading and rereading the TT2 documentation. It may as well be in Egyption Hieroglyphics. I have also gone into the source. I don't understand the source.

While my question uses a specific example, the question is a more general one. Here is a module that is used as a filter. A data stream comes into it, is modified, then returned to the program for further operations. Is there a general guide on how to replace such a filter, done by a module, with a module that uses an external program?
