A program conversion program, a program conversion apparatus and a program conversion method that conversions a program having different process according to the content of an argument into a program which facilitate the analysis are provided. The program conversion apparatus includes a dedicated call destination program generating unit that detects the call destination program, an argument for differentiating the processes of the call destination program and the content of the argument from the program group and generates a program for executing only a process according to the content of the argument of the processes of the call destination program as the dedicated call destination program for each argument and each content of the argument, and a call source program rewriting unit that detects the call position for calling the call destination program from the program group and rewrites the call position to call the dedicated call destination program generated by the dedicated call destination program generating unit.

A specification generating method for a computer program comprises the steps of: analyzing the syntax of a predetermined computer program; generating a control flowchart based on the analyzed syntax; generating an intermediate expression table based on the control flowchart; providing block numbers for calls and branched destinations; attaching an item number and a heading to every call and branched destination; and generating the specification of the computer program, using a natural language based on the item number and the heading.

Generating a natural language specification of a computer program by generating an intermediate expression table based on a flow chart from analyzed syntax of the program

A relevant-information retrieval system manages a model which describes a relevancy among a plurality of databases in accordance with associative values or a tree structure. Besides, when the retrieval system has received a search request for a certain database from a searcher, it specifies one of the databases administering information relevant to the certain database, in accordance with the model, and it presents information of the specified database to the searcher.

System and method for retrieval of data from related databases based upon database association model

The syntax of an input program is analyzed, variables substituted for the substitution sentences from an interim expression thereof are classified into categories by utilizing rules of naming variables or the data structure, and a set of substitution sentences having variables of the same kind substituted for the destinations is picked up and is converted into a table. The syntax is analyzed to obtain a syntax structure and data attribute, and the data flow is analyzed to obtain data flow information. By using such information, the use of the temporary variables in the program is judged and the temporary variables that can be erased are erased. The table conversion and the interim expression from which the temporary variables are erased are replaced by the description of a natural language to form specifications.
