Abstract

PURPOSE:To provide a program debugging method capable of easily debugging a program without preparing a debugger. CONSTITUTION:When debugging information necessary for debugging is previously displayed, a program integrating a debugging stop function for temporarily stopping a program is compiled and set up in a computer and a debugging switch for selecting whether debugging is to be executed by the computer or not is turned off to start program execution, the program can be used as a normal program by skipping the debugging stop function in the program (steps S2 to S4). When program execution is started by turning on the debugging switch, the debugging information such as a character string and a variable necessary for debugging is displayed at the time of executing the debugging stop function, and when the level value of the debugging stop function is included in the set range, the program is temporarily stopped until a continuation button is depressed (steps S2 to S13).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program debugging method for debugging a program stored in a computer.

[0002]

2. Description of the Related Art As a conventional program debugging method, for example, a debugger-using debugging method is used in which a code that can be recognized by a debugger is prepared when compiling the program and information inside the program is displayed when the debugger executes the program. Also, a trace debugging method has been proposed in which a program is traced and debugged by a system analyzer or the like.

[0003]

However, since the debug information is required in both the conventional debug method using the debugger and the trace debug method described above,
There is an unsolved problem that it is difficult to debug a program when there is no debugger suitable for the newly developed system or device.

Therefore, it is an object of the present invention to provide a program debugging method which makes it possible to debug a program relatively easily even when there is no debug information in advance.

[0005]

In order to achieve the above object, a program debugging method according to a first aspect of the present invention is a program debugging method for debugging a program stored in a computer. Compile by incorporating a predetermined debug function that displays information and pauses program execution, searches for the debug function during debugging, displays the debug information at the debug function position, and pauses program execution, After that, when the temporary stop cancel command is input, the next debug function is searched.

A program debugging method according to a second aspect is the program debugging method according to the first aspect, wherein a level number is added to the debug function, and the level number can be designated when searching for the debug function. I am trying. Further, the program debug method according to claim 3 is characterized in that it is configured such that it is possible to search for a debug function and execute or skip the debug function.

[0007]

In the program debugging method according to the first aspect, a predetermined debug function for displaying debug information necessary for debugging and suspending program execution is compiled in the program, and the program is in an operating state during debugging. As when I searched for the debug function,
While displaying the debug information at the debug function position,
Execution of the program is paused, and the programmer can perform predetermined debug processing based on the displayed debug information. By ending this debug processing and inputting a pause release command, the following debug function A search can be started and debug processing can be performed at each debug function position based on the debug information.

Further, in the program debug method according to the second aspect, since the level number is added to the debug function and the level number can be designated at the time of debugging, the debug processing can be performed only for the designated level number. Therefore, the hierarchical debug processing desired by the programmer can be performed. Further, claim 3
In the program debugging method according to, it is possible to set whether to search and execute or skip the debug function, so execute the debug function only when debugging,
Normally, the debug function can be skipped, and it is not necessary to remove the debug function from the program and compile it, and it can be set in the computer as it is.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a computer system to which the present invention can be applied, in which 1 is a computer and 2 is a computer 1.
CRT display connected to, 3 is also computer 1
Is a keyboard connected to. For example, a predetermined program is input from the keyboard 3 to the computer 1, and an execution button 4 for instructing the execution of this program and a continue button 5 for instructing the program continuation corresponding to a temporary stop cancel instruction at the time of debugging are provided. At the same time, as shown in FIG. 2, the initial display screen indicates whether to debug or not.
A debug switch 6 for instructing OFF, an upper limit value setting switch 7 for setting an upper limit value of a level number, which will be described later, and a lower limit value setting step switch 8 for setting a lower limit value of a level number are displayed, and these are formed on the keyboard 3, for example. The cursor key is operated to move the cursor to a desired display to make a selection.

Then, as shown in FIG. 3, the programmer first creates a desired program, then displays debug information necessary for debugging at a predetermined position in the created program, and temporarily stops the program execution. For simplification of description as a function, for example, three debug stop functions 11 to 13 are incorporated, these are compiled to create an executable program, and this is set in the computer 1. At this time, as the debug stop functions 11 to 13, for example, as shown in FIG. 4, the first debug stop function 11 is set to level 10, the second debug stop function 12 is set to level 20, and three Set the eye debug stop function 13 to level 30.

On the other hand, the computer 1 executes the processing of the debug stop function shown in FIG. 5 in the initial state when the power is turned on, and executes the debug function processing when the debug switch 6 is in the OFF state. End the process and press the execution button 4 in this state to start the execution of the set program. When the debug switch 6 is in the ON state, the debug stop function is searched for and its built-in position is determined. When it reaches, the debugging information represented by the character string and variables necessary for debugging is CR.
When the level value of the debug stop function is out of the set upper and lower limit values, the program continues to be executed, and the debug stop function level value is set to the upper and lower limit values. When the value is within the range of values, the execution of the program is temporarily stopped, and the program waits until the continue button 5 is pressed. When the continue button 5 is pressed, the temporary stop is released and the program continues.

Next, the operation of the above embodiment will be described with reference to the flowchart of FIG. 5 showing an example of the debug stop function processing in the computer 1. First, assuming that a program executable by the computer 1 that has been compiled by incorporating the debug stop functions 11 to 13 as described above is set in the computer 1, and the power of the computer 1 is turned on in this state, In step S1, the display information representing the initial display screen shown in FIG. 2 is sent to the CRT display 2, the initial display screen is displayed, and setting processing is performed. In this setting process, while the initial display screen shown in FIG. 2 is displayed, the cursor switch of the keyboard 3 is used to select the ON state or the OFF state of the debug switch 6, and the upper limit setting value of the level value of the debug stop function is set. UL
And the lower limit set value LL.

Next, in step S2, it is determined whether the debug switch 6 is in the ON state or the OFF state. If the debug switch 6 is in the OFF state, the process proceeds to step S3 and the execution button 4 is pressed. Determine whether or not
When the execute button 4 is not pressed, the process waits until it is pressed, and when it is pressed, the process proceeds to step S4 and the program that skips the debug stop function is executed. Will be terminated.

On the other hand, if the result of the determination in step S2 is that the debug switch 6 is in the ON state, the process proceeds to step S5 and it is determined whether or not the execute button 4 has been pressed.
When the execute button 4 is not pressed, the process waits until it is pressed, and when the execute button 4 is pressed, the process proceeds to step S6. In this step S6, the execution of the program is started, and then it is determined in step S7 whether or not the execution of the program is completed. When the execution of the program is completed, the processing is ended as it is, and the execution of the program is continued. If so, the process proceeds to step S8.

In this step S8, it is judged whether or not the debug stop function 11 has been entered, and when a program other than the debug stop function is being executed, the program waits until the debug stop function is entered and the debug stop function is executed. Then, the process proceeds to step S9, the display information representing the debug information such as a character string and a variable required for debugging is sent to the CRT display 2, and these are displayed, and then the process proceeds to step S10.

In this step S10, the level value L of the debug stop function is read, and this is read in the step S1.
It is determined whether or not it is within the range of the preset upper limit value UL and the preset lower limit value LL, and when L> UL, L <LL, it is outside the range of the preset upper limit value UL and the preset lower limit value LL. Then, the process returns to step S7, and UL ≧ L ≧
When it is LL, the upper limit set value UL and the lower limit set value LL
It judges that it is within the range of and moves to step S11.

In step S11, the program being executed is temporarily stopped, and then the process proceeds to step S12 to determine whether or not the continue button 5 has been pressed. If the continue button 5 has not been pressed, until it is pressed. On standby, when the continue button 5 is pressed, the process proceeds to step S13, the temporary stop of the program is released, the execution is resumed, and then the process returns to step S7.

Therefore, the debug stop functions 11 to 11
When the programmer debugs the program in a state where the program incorporating 13 is compiled and set in the computer 1, the debugging function process of FIG. 5 is started by turning on the power of the computer 1 and the CRT. On the initial display screen of FIG. 2 displayed on the display 2, the debug switch 6 is turned on and the desired upper limit setting value UL and lower limit setting value LL of the debug stop function to be executed are set. At this time, when it is desired to execute all the debug stop functions 11 to 13, the levels of the debug stop functions 11 to 13 are "10", "20", and
Since it is "30", the upper limit setting value UL is set to a value of "30" or more, for example, "30", and the lower limit setting value LL is set to a value of "10" or less, for example, "0".

When this initial setting is completed, the debug switch 6 is in the ON state, so that the process proceeds from step S2 to step S5, and the execution button 4 is pressed to
The program starts running. When the first debug stop function 11 is executed, step S
8 to step S9, the CRT display 2 displays debug information such as character strings and variables required for debugging.
Is displayed on the display screen, and then in step S10, the level value "10" of the debug stop function 11 is set to the upper limit set value UL.
And within the range of the lower limit set value LL, step S1
Go to 1 and suspend the execution of the program. Therefore, the necessary debug information is displayed on the CRT display 2. Therefore, when the predetermined debug processing is performed based on this debug information and the debug processing by the debug stop function 11 is completed, the continue button 5 is pressed. By doing so, the process proceeds to step S13 via step S12, the execution of the program is restarted, and the process returns to step S7. Since the program is not completed, step S8
, And when the next debug stop function 12 is ready to be executed, perform the same debug processing as above,
The same applies when the debug stop function 13 is ready to be executed.

When the debug processing by the debug stop function 13 is terminated and the execution of the program is restarted in step S13, the debug stop function is not incorporated after that, so steps S7 and S8 are repeated and the program is executed. When the processing is finished, the processing of FIG. 5 is finished. On the other hand, when the programmer wants to debug only a desired debug stop function instead of all the debug stop functions 11 to 13, in the initialization process of step S1 of FIG. 5, as shown in FIG. When only the debug stop function 12 of “” is executed, by setting the upper limit setting value UL to “25” and the lower limit setting value LL to “15”, for example, only the debug stop function 12 is executed. The debug stop functions 11 and 13 can be skipped, and the upper limit setting value UL is "20" and the lower limit setting value LL is "3".
By setting it to "0", the debug stop function 11
Can be skipped and only the debug stop functions 12 and 13 can be executed.

In this way, when the debugging process of the program set in the computer 1 is finished and the program is actually executed, step S in the process of FIG. 5 is executed.
Debug switch 6 on the initial display screen in the initial setting processing of 1.
Is turned off, and the execution button 4 is pressed to move to step S4 via steps S2 and S3.
Is skipped and executed as a normal program, and there is no need to separately compile a program without the debug stop function and set it in the computer 1.

In the above embodiment, the case where the three debug stop functions 11 to 13 are incorporated into the program has been described, but the present invention is not limited to this, and any number of debug stop functions may be incorporated. Is possible. In addition, the level value of the debug stop function can be omitted when all debug stop functions are executed during debugging, and when setting the level value L, an arbitrary numerical value is taken into consideration in consideration of ease of debugging. Can be set.

Further, in the above embodiment, the case where the selection on the initial setting screen is performed by the cursor keys of the keyboard 3 has been described, but instead of this, the selection instruction means such as a mouse, digitizer, or touch sensor may be used. You may Furthermore, as the display device, a CRT is used.
It goes without saying that not only the display 2 but also other display devices such as a liquid crystal display device can be applied.

[0024]

As described above, according to the program debugging method according to the first aspect, it is possible to perform the debugging process for a newly developed program without creating a new debugger, and the number of man-hours for creating the program is reduced. It is possible to significantly reduce the number, and it is possible to obtain the effect of improving the program development efficiency.

Further, according to the program debugging method of the second aspect, since the level value can be set in the debug function and the level value can be set at the time of debugging, the debugging can be performed hierarchically and the debug processing can be performed. The effect that the efficiency of can be improved can be obtained. Further, according to the program debugging method of claim 3, even if a debug function is incorporated in the program, the debug function can be executed only during debugging, and normally the debug function can be skipped and used as a normal program. After the debugging is completed, it is possible to save the trouble of creating and compiling a program in which the debug stop function is separately removed, and it is possible to improve the development efficiency of the program.
