BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an error message display method, and more particularly to an error message display method for displaying translation error information that occurs during program translation on a screen display device.

0002

[Prior Art] A conventional error message display method is to margin translation error information that occurred during program translation and the source program in an auxiliary storage device as a work file, and display the error message as a single window on a screen display device. Either display the translation error information centering on the source program where the error occurred, or split the window displayed on the screen display device and display the source program or the translation error information centering on the error during translation. The original program that became .

FIG. 8 is a block diagram showing an example of a conventional error message display method. Further, FIG. 9 is a diagram showing an example of a record format of a conventional work file 85. Further, FIG. 10 is a diagram showing an example of a display screen displaying a conventional source program and translation error information.

A conventional error message display method is shown in FIG.
As shown in FIG. 2, a compiler 82 that inputs and translates a source program file 81 outputs translation error information that has occurred to a translation error information file 83. Furthermore, the merge process 84 generates a work file 85 by inputting the source program file 81 and the translation error information file 83 and merging them.

Therefore, as shown in FIG. 9, in the work file 85, records of source program text and records of error messages, which are translation error information, are arranged in a mixed manner.

The display program 86 reads the work file 85 and displays the original program and the translation error information together on the display screen of the screen display device 87, as shown in FIG.

[0007]

[Problems to be Solved by the Invention] The conventional error message display method described above is designed to display the source program and the translation error information that occurred during translation in the same window on the screen display device. The number of lines in the program is reduced, and while referring to the translation error information, it is not possible to directly refer to the source program that causes the error during translation. It has the disadvantage that the source program cannot be referenced or modified.

[0008]

[Means for Solving the Problems] The error message display method of the present invention uses a translation error information input means for inputting a translation error information file outputted by a compiler to an auxiliary storage device, and stores a translation error information work file in an auxiliary storage device. Sort the translation error information in the translation error information work file in the order of line numbers of the source program using a translation error information work file creation means and a translation error information work file chaining means to associate the translation error information by line number. a translation error information work file update means for updating a translation error information work file using a source program input means; a source program work file creation means for creating a source program work file in an auxiliary storage device using a source program input means; and a source program work file chaining means. The record number of the translation error information work file is set in the information of the source program that caused an error during program translation in the source program work file using a means, and the source program work file and the translation error information work file are associated. When the work file necessary for the display program is completed using the translation error information association means to be updated and the display control program is executed,
Enter the translation error information work file name and the source program work file name, and the display control program executes the error information display program and the source program display program, and each program displays the translation error information in separate windows on the screen display device. While displaying the source program, each program uses inter-program communication via the display control program to pass the line number of the source program to be displayed as inter-program communication information, and displays the source program mainly using translation error information. It consists of searching for program error locations and related source programs.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the error message display method of the present invention.

The error message display method of this embodiment is as follows:
The translation error information file 3 output by the compiler 2 that inputs and translates the source program file 1 is read out using the translation error information input means 4, and created as a translation error information work file 5 in the auxiliary storage device, and the translation error information file 3 is outputted by the compiler 2 that inputs and translates the source program file 1. Using the work file chaining means 6, records in the translation error information work file 5 are chained and updated.

Next, the source program input means 7 is used to input the source program file 1 to create a source program work file 8 in the auxiliary storage device, and the source program work file chaining means 9 is used to create the source program work file 1. 8 and update the chain.

Next, in order to associate the translation error information with the source program, the translation error information association means 10 associates the source program work file 8 with the translation error information work file 5 by using line numbers of the source program. Based on this, the translation error information work file 5 and the source program work file 8 are linked by their respective record numbers, and information necessary for finally displaying them is set and chained.

Next, the display control program 11 is executed in order to refer to the translation error information and the source program. At this time, the name of the work file in which the translation error information and the source program are stored is input and specified, and the display control program 11 executes the error information display program 12 and the source program display program 13 to display the screen display device 1.
4, each program displays translation error information and the source program in separate windows.

FIG. 2 shows the display control program 11 in this embodiment.
FIG. 3 is a diagram showing an example of a display screen immediately after being displayed by the error information display program 12 and the source program display program 13 executed by. Further, FIG. 3 is a diagram showing an example of a display screen in which line number 001000 in FIG. 2 is specified and related translation error information is shown.

If you want to refer to the source program at line number 001000 of the error display program in the state shown in FIG. 2, position the cursor on the error display window to 001000 and press the execute key, and the source program window will open as shown in FIG. , the source program is displayed starting from line number 001000. At this time, the error information display program 12 sends the line number 001000 and the record number of the source program work file 8 set in the record of the translation error information work file 5 to the display control program 11 using inter-program communication. Therefore, the display control program 11 that has received the information transmits the line number and the record number of the source program work file 8 to the source program display program 13 using program communication. 13 displays a source program window as shown in FIG. 3 from the received line number and the record number of the source program work file 8.

FIG. 4 is a diagram showing an example of a display screen that changes to a state showing a line number having error information by pressing the execution key in the state shown in FIG.

When the execution key is pressed at the current position displayed in the source program window in the state shown in FIG. 3, the error display window is displayed as shown in FIG. In this way, by selecting on any window, it becomes possible to refer to the position of the source program in which the error occurred or the line of the source program that is closest to the source program in error.

That is, when selected in the error display window, the error information display program 12 sends the line number and the record number of the source program work file 8 as information to the error display control program 11 through inter-program communication. The received display control program 11 transmits the information through inter-program communication, and the received source program display program 13 displays the received information in the source program window starting from the position of the line number that is the display request. By using inter-program communication in this manner, display can be freely performed via the display control program 11.

FIG. 5 is a diagram showing an example of the record format of the translation error information work file 5 of this embodiment.

As shown in FIG. 5, the translation error information work file 5 has a record structure including its own record number, line number of the source program, error message, record number of the source program work file 8, and its own record. It consists of a previous record number, which is the record number before the current record, and a subsequent record number, which is the record number following the own record. Additionally, if your own record is the first record of the translation error information work file 5, 0 is set in the previous record number, and if your own record is the last record, 0 is set in the subsequent record number. There is.

FIG. 6 is a diagram showing an example of the record format of the source program work file 8 of this embodiment.

As shown in FIG. 6, the source program work file 8 has a record structure including its own record number, line number of the source program, source program text, record number of the translation error information work file, and its own record. the previous record number, which is the previous record number,
It consists of the next record number, the next record number. Additionally, if the own record is the first record of the source program work file 8, 0 is set in the previous record number, and if the own record is the last record, 0 is set in the next record number. .

FIG. 7 is a diagram showing an example of the relationship between the translation error information work file 5 updated by the translation error information association means 10 and the source program work file 8 in this embodiment.

As shown in FIG. 7, the two files exist independently, but the relationship from the translation error information work file 5 to the source program file 8 is as follows for each record of the translation error information work file 5 in FIG. The source program work file 8 is associated with the record number of the source program work file 8, and conversely, each record from the source program work file 8 is associated with the record number of the translation error information work file 5.

[0026]

[Effects of the Invention] As explained above, the error message display method of the present invention allows the source program and the translation error information to be displayed and referenced as separate windows on the screen display device, while the translation error information is simultaneously referenced. Since you can display and refer to the error information and the source program that has the same line number, you can refer to and modify the source program based on the translation error information, and if an error occurs during program translation. This has the effect that when removing the cause of an error in a source program, it becomes easier to refer to and correct the source program that caused the error during program translation.
