Abstract: A device supporting the structural analysis of a module comprises: a storage means storing at least one module; and a conversion means that converts a prescribed target module among the modules stored by the storage means to a secondary module and stores same in the storage means. The conversion means reads the target module from the storage means and sequentially outputs to the secondary module each sentence written from a prescribed processing start location in the target module to a prescribed processing end location. The conversion means also recursively develops a sentence written in processing units etc., for execution, and outputs same to the secondary module, when the sentence is a module internal processing unit or a sentence that executes another module.
