PURPOSE:To obtain the accurate correspondence between a control structure and a source program and to decrease the time required for production of a program controlled constitution diagram, by analyzing the source program to extract the information on the calling relation in the program and producing automatically a program controlled constitution on the basis of the extracted information. CONSTITUTION:A source program group 1 to be produced is analyzed by a program analyzing device 2, and the information on the calling relation of a program is delivered from a tree structure data group 3. The group 3 and a control graph producer 4 produce a program control structure having directivities of both calling and called sides. In this case, the program name is given from a program name designating part 5 for the initiation node of a graph having directivity. The control graph data 6 of the producer 4 is added to a box layout data producer 7 and a connection data producer 8 to deliver the box layout data 9 and inter-box connection data 10 are delivered on the basis of the data 6. Then a plotter 11 produces automatically a program controlled constitution 12 from the data 9 and 10. |
