Thanks for the explanation. I'm familiar with relational languages (SQL), multi of course, things that are hard to classify like Rebol, and a little Simulink (no LabVIEW though). I had completely forgotten about those....I wonder how many exist in practice? I appreciate you drawing the distinction between TRS operating on rules and things like Prolog being a rules based system using facts. TBH, I only understand much of this at a very superficial level (as in I've played with Prolog several times and even read a short book, but I'd never choose it for a production application if I can get away with using SQL and some procedural code lol).
