Well I don't mean to brag but I competed in the "Simatic Find Info Games" in the winter of '86, got a bronze in abstract thinking class !!
there was only one world record set that year, by a AB Engineer for different ways of programming the same Traffic Light, 952 different programs if I remember correctly, of course the Irish AB specialist received the lowest honour for a one line program to switch a light ON, It read "Switch On" > Light On. very complex..
