Abstract: Firstly, definitive identifiers are determined, which are the screen needed for the software to be produced. Next, words existing in the definitive identifier are sorted out, as well as the homogeneity map is created where all pallets needed for the software are placed according to the process flow based on the definitive identifier. Next, the necessary file is determined based on the sorted-out words and the created homogeneity map. Next, the following tense control vectors are created: the first tense control vector that implements screen editing or file editing for all the sorted-out words; the second tense control vector that determines the homogeneity route for all the sorted-out words; and the third tense control vector that implements file updating.

Abstract: First, a defining member identifier constituting a screen required for software to be produced is determined. The words contained in the defining member identifier are then taken out, and a processing path diagram in which all pallets required for the software are arranged on the basis of the defining member identifier and along a flow of a process is prepared. A required file is then determined on the basis of the extracted words and prepared processing path diagram. A first base logic for editing screens or files for all of the extracted words, a second base logic for determining a processing path and a third base logic for updating a file are then prepared. Three kinds of pallets in which the first to third base logics are bound on a screen basis and pallet functions for executing these base logics autonomously and significantly in the pallets are then prepared.
