Alexander Laemmle (also Beowolf, flowoeB) was the first person to realise the potential of the agent scripting language, CAOS. He created the first COS tool (BORG, later COE), and in fact penned the term 'cos file'.
His original COS tool, based on the scripting language information sent to him by Steve Grand, was the first of its kind. It was used by Mark Ashton for all Creatures 1 add-on COBs until Creature Labs developed their own CAOS tool, and was available with his COBs at his website, Beowolf's Homepage.
