There are various CAOS commands to access/change them, OBVx (used in C1 and C2) and OVxx (C2 and above), for accessing the variables of TARG, and MVxx (C3 and above) for accessing the variables of OWNR, where 'x' is replaced by a number (for example, OBV1 for variable 1, or OV12 for variable 12). Creatures 1 has 3 OBVx variables, 0 to 2, with C2 having 10 OBVx variables, 0 to 9. C2 and the other games have 100 OVxx variables, from 0 to 99.
Object variables are useful for when an object has to 'remember' something - for example, if a critter has to remember if it's hungry or not, or to simulate evolution.
When a script begins running, they are initially all 0 (integer type), but can be assigned any value in C2e, and integer or agent in C1 and C2, though agent references in OBVx variables in C1 become invalid on game close, and can crash a game when used after restart.
