    ABSTRACT:: A memory model for a robot has been designed and tested in a
               simple toy-block world for which it has shown clarity,
               efficiency, and generality. In a constrained pseudo-English
               one can ask the program to manipulate objects and query it
               about the present, past, and possible future states of its
               world. The program has a good understanding of its world and
               gives intelligent answers in reasonably good English. Past
               and hypothetical states of the world are handled by changing
               the state of the world in an imaginary context. Procedures
               interrogate and modify two global databases, one which
               contains the present representation of the world and another
               which contains the past history of events, conversations,
               etc. The program has the ability to create, destroy, and even
               resurrect objects in its world.
