Abstract
Abstract A functional relation between components which can be extracted from an already existing program in advance is automatically extracted by a computer, or such a functional relation which cannot be extracted is defined by a developer, so that the preparation of a program by combining the components is assisted. A dictionary registration unit reads a source code file, analyzes, extracts a component definition, and extracts from the component definition information a counterpart component name, interface name, and interface definition, and registers component name, counterpart component name, interface information of the interface name, and interface definition body in a dictionary. Furthermore, when there is no source codes, the developer inputs the interface information from an input-output device, and registers in the dictionary. A program editing processing unit, on the basis of a user's indication, retrieves and displays a list of interfaces between components, and also extracts the interface definition from the dictionary, thereby to assist the user in preparing a program by combining the components.
