Yep, the 'ifused' field was a little miracle, I think many failed to realise how elegant and simple fpi actually was, of course not as versatile or advanced as other scripting languages but a great way for beginners to learn and that's what FPSC was about.
Going a little further you could even trigger with different ID numbers 1-whatever and activetifused=x, activated=x followed by any action you wanted, even randomising actions with it or triggering secondary scripts to run.
Heady days
