PROBLEM TO BE SOLVED: To provide a method for customizing built-in software without correcting the source code of base software at all. SOLUTION: This built-in software is provided with a base class, an instance table 112 for registering/referring to instances and class designations, a base software part 11 configured of codes for managing execution control and a custom software part 12 configured of derived class codes defined/mounted by referring to the header file of the base class. In preparing an ROM, the base software part 11 is linked to the custom software part 12, and in the case of execution, the instance and class designations of the derived class are registered in the instance table in the constructor of the base class, and the instances of the derived class are called from the compiled module.
