'''20:''' [[BIGOBS.PCK]] reference (pointer to graphic for inventory)

'''21:''' [[FLOOROB.PCK]] reference (pointer to graphic for item on ground)

Tertiary use: Timer for "grenade", if Grenade ([44]) is true. Only works if item is ammo ([49]). If it is then e.g. since Blaster has a 1 here (1 bomb per blaster "clip"), it will explode at end of turn 1 (if not being held in inventory).
