1. A computer software design supporting method in an information processing system for designing a general purpose computer program specification from a plurality of software modules represented by a plurality of software module specifications of various types, the modules being modified using said information processing system which includes a supervisory CPU, an input device connected to the CPU, a specification data table connected to the CPU and an output terminal connected to the CPU, the design supporting method comprising the steps of:

  • inputting into the information processing system through the input device correlation information for correlating i) items to be described in the general purpose computer program specification with ii) said plurality of software module specification of various types;

    storing the inputted correlation information in said specification data table;

    inputting into the information processing system through the input device a modify command for modification of a content of a first item of a one of said plurality of software modules described in said computer program specification; and

    ,analyzing said computer program specification using said CPU to generate a signal representative of a first portion of said computer program specification possibly affected by said modification of said content of said first item described in the computer program specification based on the inputted correlation information when such modification is made, the analyzing step including a step of classifying, with the CPU, the first portion possibly affected by said modification into one of;

    i) a first classified portion automatically modified by the information processing system, ii) a second classified portion needing modification by the information processing system but whose content of modification cannot be analyzed, and iii) a third classified portion related to the modified portion but whose need for modification cannot be analyzed by the information processing system.
