1. A method for organizing information in a memory of a computer system, the memory having an address space for an object-oriented operating system and an address space for an application program, the method comprising the steps of:

  • (a) storing information defining a container class in the operating system address space of the memory, the container class being comprised of a data structure for holding information, a member function for constructing a container object from the container class, a first member function for inserting information identifying a containable object into the data structure, plurality of member functions for performing editing operations and a second member function for inserting information identifying an editing operation into the data structure;

    (b) executing the constructing member function to instantiate a container object in the application program address space of the memory;

    (c) executing the first inserting member function of the instantiated container object to insert information identifying a containable object into the data structure of the instantiated container object;

    (d) executing one of the editing member functions in the instantiated container object to perform an editing operation on the containable object identified by information in the data structure of the instantiated container object; and

    (e) executing the second inserting member function to insert information identifying the editing operation performed in step (d) into the data structure of the instantiated container object so that the editing operation may be undone and redone.
