Abstract
A procedure is provided to implement modifications to a running object-oriented program, in particular a program for controlling an automation facility. The program is stored temporarily in a memory in the form of an intermediate code which can be converted into executable machine code in runtime. The method includes the steps of providing a modified program or a modified program module, also in the form of an intermediate code, and comparing the intermediate code of the modified program or that of the modified program module with the intermediate code of the running program for determining the modifications, and implementing modifications to the running program. A correspondingly adapted run-time system is also provided, which is suitable for implementing the procedure as well as the integration of this run-time system into an automation facility.
