It occurs in the distributed processing application system abundantly that the business form of the applicable object changes in the postproduction and contents of a service of the applicable business change. The evolution of the system and we cause the phenomenon of such a change. And it aimed at the establishment of the system construction technique which can cope with it flexibly dynamically in the phenomenon which wasn't expected, and the evolution, and the policy that the executive part of the business function was separated from the part which had the nature of the behavior in the accomplishment of the business was adopted. As for this system, the mechanism of invocation of the function program which realizes a presumed role must be provided. The form that the function program which coped with it was chosen based on the technique of pattern matching and which started it was realized as a mechanism of the invocation interface from a group of parameters in the recursive function so far. But, as for the system that we must almost correspond perfectly with the thing which the group of parameters to find is necessary for and evolves, it becomes a big restriction with this form. It doesn't depend on a formal pattern which a program itself is provided with for the purpose of making this restriction endlessly small and to have, but it pays attention to the role as a nature which a function program has, and a pattern based on the general idea of the semantic classification of this nature is introduced newly with main subject. The group of the function program which can become the candidate who adapts itself to the pattern introduced newly is extracted. A mechanism which evaluates function, performance, condition and so on and which chooses the most suitable thing from this group and to start is examined.
