<p>PROBLEM TO BE SOLVED: To provide a computer program product, used by a computer system to execute processing of environment simulation. SOLUTION: The program product consists of plural service programs, and these service programs are constituted so that an attribute to be simulated of objects of an environment under processing to be simulated may be determined as a whole. At least several programs among service programs consist of attribute access programs. A data port program is constituted so that it can be operated during execution of service programs. The data port program is related to a selected service program, which connects the selected service program to an external environment. The selected service program and the data port program entirely perform mutual communication of an attribute value between the environment to be simulated and the external environment.</p> |
