1. A computer system, comprising:

  • computer hardware for performing native system services;

    a procedural operating system, having a native interface, for controlling the computer hardware to perform the native system services;

    object oriented methods requiring native system services;

    procedural program logic code, responsive to invocations of the object-oriented methods during runtime, for causing the procedural operating system to control the computer hardware to perform the required native system services;

    executable program memory associated with the computer hardware for runtime execution of the procedural operating system, invocations of the object-oriented methods and related portions of the procedural program logic code;

    means for making determinations during runtime execution if object-oriented methods to be invoked are present in the executable program memory; and

    a runtime loader, responsive to the determinations, to selectively load required object-oriented methods into the executable program memory during runtime before invocation of the object-oriented methods.
