Abstract
Upon receiving a program S1 from a manager device M1, a program execution section 2 starts executing the program S1 and calls an API by linking an enhanced operational object EO1. The enhanced operational object EO1 executes the called API. When access to a managed object MO1 is required, the API supplied by a primitive operational object PO1 is called. The primitive operational object PO1 executes the API, accesses the managed object MO1 and returns the result to the enhanced operational object EO1. The enhanced operational object EO1 returns the result to the program S1. The program execution section 2 returns the execution result of the program S1 to the manager device M1.
