Object-oriented operating system

A method for operating a computer system, comprising the steps of:

• executing a procedural operating system on computer hardware, the procedural operating system including a native interface, responsive to procedural function calls, for providing native system services;
• issuing calls during runtime, compatible with the native interface, to provide the native system services in response to invocations of object-oriented methods requiring such native system services;
• determining during runtime if object-oriented methods to be invoked during runtime execution are present in executable program memory associated with the computer hardware;
• and
• selectively loading the object-oriented methods into the executable program memory during runtime before invocation thereof, if not yet loaded.

A method for operating a computer system, comprising the steps of:

• executing a procedural operating system, based on Windows or Unix operating systems, on a Unix or IBM compatible computer hardware environment;
• providing an object-oriented interface, executing on the computer hardware environment, and responsive to object-oriented programming, for instantiating objects from object-oriented classes, encapsulating data for exclusive use with each object, and invoking object-oriented methods in the objects for operating on the encapsulated data;
• providing procedural programming logic code, responsive during runtime to selected ones of said invoked object-oriented methods requiring native system services, for issuing procedural calls, compatible with a native interface of the procedural operating system, to cause the hardware environment to provide the native system services in response to the object-oriented methods;
• and
• loading the methods during runtime before invocation thereof;
• whereby a choice of which system implementation to use can be deferred to run-time.

A method for operating a computer system including a memory, comprising the steps of:

• said library including second procedural program logic code which is responsive to invocations of object-oriented methods, for causing a procedural operating system to control the computer system to perform second type native system services different from said first type;
• executing a procedural operating system in the memory, the procedural operating system including a native interface responsive to procedural function calls, for providing native system services;
• running an object-oriented program in a task address space of the memory, the program including an object-oriented method requiring the second type native system services;
• determining during runtime whether said second type procedural program logic code is available in said task address space;
• and
• loading said second type procedural program logic code into said task address space during runtime.
