PURPOSE:To discriminate whether development in another manner is possible or not based on display of the tree of structure displayed on a screen by providing a module for grammatical guide and a module which generates this module. CONSTITUTION:A module for grammatical guide based on information of the structure and a module 5 which generates this module 4 based on grammar of the structure described by the user of a software system are newly coupled besides constituting elements of a module 1 which holds information of the structure and a module 2 which displays the structure in a form of tree based on information of the structure. Thus, the displayed structure is kept grammatically correct, and in this state, it is clearly discriminated whether development in another manner is possible or not by the tree of the structure displayed on the screen of a display device.
