PURPOSE:To stop optionally while the flow of a program is confirmed during the execution by applying a variable symbol to a processing block of a flow chart of the program displayed at a CRT, and changing and displaying the color. CONSTITUTION:When a program to be debugged is started by a debugging program, a CRT displaying device of a time sharing system TSS terminal device 18 is divided into plural monitoring scopes, and the flow chart of the program to be debugged is displayed. In such a case, the executing position of the program is displayed by changing the color of an applied start symbol and end symbol. Namely, for example, the color of the start symbol is green before the starting of the processing of the block, it is changed to red at the time of starting and changed to pink after the completion of the processing. Thus, stopping can be optionally executed while the flow of the program during the execution is confirmed, the software can be easily debugged and the accuracy can be improved. |
