Abstract

PURPOSE:To simultaneously produce both the specification information and the detailed information by applying a structure formation programming technique, calling out a macro-original sentence which is previously produced in the stepped production of a program, and obtaining the detailed information and its corresponding specification information. CONSTITUTION:A called sentence analyzing part 103 is provided together with a real parameter holding part 104, a macro-reading part 105, a macro-holding part 106, a distributing part 107, a parameter solving part 111, a processing evolving part 113, etc. Furthermore a structure formation programming technique is applied. A diagram program editor backs up the stepped development of a program including a rough design, i.e., the production of the specification information through a detailed information, i.e., the production of the detailed information. Then the program editor designates a macro-calling sentence at production of the specification information. Thus, it is possible to evolve both the specification information and the detailed information from a macro-original sentence in accordance with the contents required by a user.
