CATX is a CAOS command introduced in Creatures 3. It returns the name of the given genus category when used, like manky or fruit, using the catalogue tag "Agent Categories". For a full list, see Classification system. It is used in the games to make an object say its genus name when the hand clicks on it, helping teach creatures their vocabulary. If the ID is not within the catalogue tag, CATX will return an empty string.
