KI9-91-002 ABSTRACT OF THE DISCLOSURE Object Based System for Software Maintenance A computer implemented system and method for automatically generating an executable version is based on component objects and events. Object-oriented language concepts of encapsulation, inheritance, and message passing are employed to simplify the specification and execution steps. Software maintenance includes the steps of assembling executable systems from defined component parts such as source code files and object code files. An object definition is provided for each software component containing a specification of its dependency upon other objects and processing methods that must be executed to create that object. An event definition is created for each process that is to be applied to the component objects. The event definition includes a specification of any prerequisite events and conditions for delivery of the event message. An object dependency interpreter is provided to recursively control the passing of events to the objects for action. It ensures that any prerequisite events are first executed and that any objects upon which the current object is dependent are processed before the present object. Inheritance is employed to simplify object definition through the definition of generic objects which the object dependency interpreter instantiates for processing. Mapped memory is used to store an object data structure containing the representation of component objects and event objects. Additional storage is used to retain component object file system status.
