Frame

An unordered collection of slots, each of which consists of a name and value pair. The value of a slot can be any type of object, and slots can be added or removed from frames dynamically. A frame can have a user-specified class. Frames can be used like records in Pascal and structs in C, and also as objects that respond to messages.
