Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a debugging method for debugging an electronic computer program, and particularly to a source program debugging method.

(Prior Art) Fig. 3 is a block diagram showing a conventional program debugging method disclosed in, for example, Japanese Patent Application No. 1987-78758. In Fig. 1, 11 is a source code file, and the source code 12 is a source code analysis program that analyzes the source code read from the source code file 11 and executes it in a simulated manner.13
is the processing result file, source code analysis program 1
Stores the processing results obtained as a result of the simulated execution associated with the execution of step 2. A setting data file 14 is controlled by an input device 15 and provided to the source code analysis program 12, and a command from the input device 15 controls simulation execution based on the setting data. Reference numeral 17 denotes an output device, which is automatically controlled by input from an operator or program control, and outputs part of the contents of the processing result file 13 as processing result data 16.

Next, the operation will be explained.

A source program specified by an operator's instruction is input from the source code file 11, and this input source program is sent to the source code analysis program 12.
The input device 15 accesses the setting data file 14, imports the stored setting data, and stores the analysis result in the processing result file 13 (first program execution process). The source code analysis program 12 executes a simulation based on the data and the processing result file data stored in the processing result file 13 (second program execution process), and stores the execution result in the processing result file 13 again.

Here, the output device 17 is controlled according to an instruction from an operator or under program control to output a part of the processing contents as processing result data 16.

(Problem to be solved by the invention) Since the conventional program debugging method is configured as described above, the debugging method that analyzes and executes it in a simulated manner analyzes all of the specified source code from the beginning to the end. A simulation must be executed, it takes time to select data when debugging a desired process, and a large amount of data must be set for this purpose. In addition, if checkpoints are not set in the program source, debug result output operations cannot be executed, so it is necessary to set checkpoints in the set program source after debugging is completed, and this is proportional to the scale of the debug program. This poses serious problems, such as requiring a huge amount of time to input the checkpoint settings, and inducing new debugging by making unnecessary modifications to the program source to be debugged.

This invention was made to solve the above-mentioned problems, and by specifying from any point to any point in a specified source program, the source program can be edited without changing the source program in any way. It is an object of the present invention to provide a program debugging method that allows debugging a desired series of program execution processes in an arbitrary range of a program with a small amount of setting data, and that also allows selective output of debugged processing results without specifying them in the source program. purpose.

(Means for Solving Problems) A program debugging method according to the present invention arbitrarily determines a program execution range by referring to source program execution range data stored in a range specification file immediately before a first program execution process. The first step is to specify the specified program execution range. The second program execution process is performed, and the first program is executed by referring to the checkpoint data stored in the checkpoint file. Processing result data obtained by the second program execution process is selectively output.

(Operation) The program debugging method according to the present invention arbitrarily specifies a program execution range by referring to the execution range data of the source program stored in the range specification file immediately before the first program execution process by the execution range specification process, The first and second program execution processes are performed for the program execution range specified by the execution range specification process, and the first and second program execution processes are performed with reference to the checkpoint data stored in the checkpoint file by the data output process. Processing result data obtained by the second program execution process is selectively output.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, l is a specified range data file which is a range specification file of this invention, and a source code file ll
Specified range data to be executed for the source program stored in is stored. The designated range data and checkpoint data stored in the designated range data file l are stored in a rewritable manner from the input device 15. 2 is a checkpoint data file in which a program execution range is arbitrarily specified by referring to the specified range data of the source program stored in the specified range data file l immediately before the first program execution process, and the specified program execution range is About 1st. Checkpoint data for selectively outputting processing result data obtained by the second program execution processing is stored.

Next, the program debug processing operation according to the present invention will be explained with reference to the flowchart shown in FIG.

FIG. 2 is a flowchart illustrating a program debugging process according to an embodiment of the present invention.
51' (12) indicates each step.

First, initialize the processing result file E3 (step 5).
r(i)), then read the specified range data to be simulated in the source program from the specified range data file l by accessing from the input device 15 Step 5
T(2)), Set the start and end pointers of the source program, that is, find the start and end of the specified range of the source program (Step 5T(3)), Next, the source code read from the source code file 11 is set as specified above. Step 5T(4)) is used to determine whether or not it is within the specified range based on the range data. If NO, program execution is stopped.

If YES, the source code analysis program 12 analyzes the source code read from the source code file 11 (step 5T(5)), and the data input processed by the source code analysis program 12 is processed in the processing result file 13.
(step 5T(6)). If the determination is YES, the processing results are stored in the processing result file 13. Read the data (step 5T(7)) and proceed to step 5T(9) onwards. If NO, read the setting data (test data) stored in the setting data file 14 (step 5T).
(8)), then execute source code analysis processing (second program execution processing) based on the setting data or processing result data read in step 5T(7) or step 5T(8) (step 8). (9)), storing the processing result obtained by the second program execution process in the processing result file 13 (step 5T(10)),
Next, it is determined whether the processing result stored in the processing result file 13 is specified by the checkpoint data stored in the checkpoint data file 2 (step 5T(11)); if NO, step 8
Returning to step (4), if YES, edit the processing result data 16 and output it from the output device 17 in step s'r(iz
)), return to step 5T(4).

This makes it possible to debug only a specified desired range of source programs, and also selectively output processing results.

(Effects of the Invention) As described above, according to the present invention, a source program that arbitrarily specifies a program execution range by referring to source program execution range data stored in a range specification file immediately before the first program execution process. First, regarding the program execution range specification process and the program execution range specified by this execution range specification process. The second program execution process is performed, and the first program is executed by referring to the checkpoint data stored in the checkpoint file. Since the configuration is configured to execute the data output process that selectively outputs the processing result data obtained by the second program execution process, any specified range in the source program can be executed without any modification to the source program. Since only a desired series of programs can be debugged with a small amount of rewritable setting data, debugging work can be performed efficiently in a short time. In addition, the checkpoint data allows you to select and specify the processing result output necessary for debugging obtained from the source program execution process, which makes it possible to eliminate the process of writing checkpoint data to the source program, significantly reducing debugging time. It has a great effect.
