Description

Description: TECHNICAL FIELD The present invention relates to an information processing apparatus that executes various processing tasks based on a program input from the outside, and particularly, to an information processing apparatus for each line that configures the program when the program is loaded. The present invention relates to an information processing method and an information processing apparatus that improve the coping method when an error is detected by determining the correctness of program data.

[Prior Art] There are two types of programs that an information processing device loads from a device connected to an interface line such as GPIB, RS232C, or an auxiliary storage device such as a floppy disk device.

One is that the program stored in the program storage memory of the information processing device is output to an auxiliary storage device or an external storage device and saved. It has been confirmed that such a program has no error by first checking the validity of each line of program data at the stage of storing the program in the program storage memory. Therefore, no error will occur when loading such a program.

The other is a program created by another information processing device or a program created by the same information processing device, not by a regular program input operation but by a general-purpose editing function. is there. When such a program is loaded, an error may occur because the validity of the program data of each line making up the program is first determined at the time of loading.

The latter form of the program does not occupy the information processing device that tries to execute the program, and is useful when it is desired to create the program using another information processing device.
Further, it is useful when there are a plurality of types of information processing devices and a program already running in one information processing device is loaded and used in another information processing device. However, such programs may contain errors as mentioned above. The cause of the error may be an input error at the time of inputting the program, or a different programming language rule depending on the information processing device. In this case, even if the program includes an error, the other part can be used as it is by correcting only the error part. Therefore, if the entire program can be loaded without stopping the loading of the program, the utility value is great.

Conventionally, when an error is detected during program loading,
As a method to continue loading, there was a method found in the GET command of the HP series 200 computer manufactured by Yokogawa Hewlett-Packard Co. On this computer,
If there is an error in any of the program data while loading the program with the GET command, the erroneous program data will be reported to the operator, and the program data will be changed to the commented program data until the end of the program load. continue.

In addition, as another conventional method, PA manufactured by Anritsu Corporation is used.
There was also a method found in the LOAD SOURCE command of the CKET V series personal technical computer. In this computer, if program data containing an error is detected while loading a program with the LOAD SOURCE command, the program data containing this error is displayed on the CRT display device, and the operator operates the keyboard to correct the displayed content. You can then enter. If the contents corrected and entered by the operator are valid, the program continues to load.

[Problems to be Solved by the Invention] However, the above-described conventional program loading method has the following problems.

First, the method of changing the program data with an error to the program data indicating the annotation and continuing the program loading has the advantage that the operator can load without intervention, but after the loading is complete, the program data containing the error can be It was difficult to reliably search and correct. The program data having an error is converted into program data indicating an annotation and stored in the program storage memory, and this program data has exactly the same format as the program data indicating another annotation. Therefore, when the program data containing the error reported by the computer is corrected after the program has finished loading, if there is a mistake in correcting it, the program containing the error that remains uncorrected from the contents of the program itself It is impossible to retrieve data automatically. Therefore, after that, at the stage of executing the program, there is a risk that the wrong content is executed without realizing that the program data including the error remains changed to the program data indicating the annotation.

Next, the method of waiting for the operator's correction input each time program data containing an error is detected while loading the program has the advantage that the program data containing the error can be reliably corrected to the correct contents. There was a drawback that the operator had to intervene until the end of. Especially when there are many error points and the number of errors cannot be predicted,
The operator had to continue operating the computer until the loading was finished, which was a heavy burden.

The present invention has been made in view of such circumstances, and when an error is detected in the program data of each input line, the program data contains an error at a predetermined position in the program data including the error. The program data can be continuously executed without intervention by the operator by adding specific additional information that treats this program data as one message and forcibly changing it to formally valid program data. An object of the present invention is to provide an information processing method and an information processing apparatus that can reliably search for and correct an error later and can operate a correct program.

[Means for Solving the Problems] In order to solve the above problems, in the information processing method of the present invention, the program data input analysis means determines the correctness of the program data of each line forming the program sequentially input from the outside. If the relevant program data is judged to be valid, the relevant program data is stored in the program storage memory, and if it is determined that the program data contains an error, this program is placed at a predetermined position in the relevant program data by means of error forced correction means. By indicating that the data includes an error and adding specific additional information that regards the relevant program data as one message, the relevant program data is forcibly corrected to formally valid program data, and the forcibly corrected program data is Re-input to program data input analysis means Then, the validity of the re-input program data is determined again, and when the relevant program data is determined to be valid, the program data is stored in the program storage memory, and the program data of all the lines that make up the program is stored. Is stored in the program storage memory and then the program data of each row stored in the program storage memory is searched for the program data to which the additional information is added,
The error of this retrieved program data is corrected.

Further, in the information processing apparatus of the present invention, the program data input analysis means, the error forced correction means and the program storage memory are provided, and the correctness of the program data of each line constituting the program sequentially input from the outside is input as the program data input. An information processing device for storing the relevant program data in a program storage memory after confirmation by the analysis means, wherein the program data input analysis means detects program data including an error in the process of confirming the correctness of the program data of each line. Then, this program data is sent to the error compulsory correction means, and the error compulsory correction means indicates that this program data contains an error at a predetermined position in the program data including the error received from the program data input analysis means. The corresponding program data is By adding specific additional information regarded as a sage, the corresponding program data is forcibly corrected to formally valid program data and re-input to the program data input analysis means.

[Operation] With the information processing method and the information processing apparatus configured as described above, for example, when a program is loaded from an external device such as a host computer to the information processing apparatus, the program data of each line configuring the program is added. If there is no error, it is directly stored in the program storage memory via the program data input analysis means.

On the other hand, if there is an error in the program data of each line, the program data including the error is forcibly corrected by the error forced correction means with additional information to formally correct program data. Therefore, the forcibly corrected program data is stored in the program storage memory via the program data input analysis means.

That is, in the program storage memory, the program data having legal contents from the beginning and the program data having specific additional information and modified formally to be legally stored are mixed and stored.

Therefore, when the program storage memory is searched for with specific additional information, the program data including an error can be specified. Therefore, the operator may correct the program data including the retrieved error into correct program data by using, for example, a CRT display device or a keyboard.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the schematic arrangement of an information processing apparatus to which the information processing method of the embodiment is applied. This information processing apparatus is roughly divided into program data input analysis means 1
The error compulsory correction means 2, the program edit creation means 3, the program execution means 4, and the program storage memory 5. Incidentally, in practice, each of the means 1
Reference numerals 4 to 4 are formed by respective unit programs (subroutines) constituting the control program stored in the information processing apparatus.

The program data input / analysis means 1 sequentially inputs program data of each row constituting a program to be written in the program storage memory 5 of this information processing apparatus from an external device 6 such as a host computer via an I / O driver 7. To be done. An input device 8 such as a keyboard and a display device 9 such as a CRT display device are connected to the program editing / creating means 3 via I / O drivers 10 and 11, respectively. Similarly, the program execution means 4 has the I / O
The input device 8 and the display 9 via the drivers 10 and 11
Is connected.

Further, the program editing / creating means 3 includes a program display means 3a, a program data editing means 3b, a program data output means 3c, a program data cursor moving means 3d, and an error program data searching means 3e, as shown in FIG. It is composed of five unit programs.

Further, in the program storage memory 5, an area for storing the program data of each line forming the program input from the external device 6 for each line according to the line number is formed.

Next, the operation of each means constituting this information processing apparatus will be described step by step.

First, the program data input analysis means 1 is an external device 6
It has a function of confirming the correctness of the program data of each row constituting the program sequentially input from and writing it to the next program storage memory 5. Further, the error compulsory correction means 2 has a function of attaching specific additional information to the program data including an error and forcibly correcting it to formally valid program data.

The validity of the program data is determined by the following procedure. That is, the program data of each line forming the program is roughly classified into three types. The first type, as shown in FIG. 5A, is composed of a line number, a general statement such as an imperative statement, and an argument following the general statement. In this case, a certain rule exists in the type (numerical value / character string / mathematical formula / character string expression / symbol) and order of the arguments following this general statement corresponding to the type of general statement. The second type is composed of a line number, a REM (remark) statement, and a character string following this REM statement, as shown in FIG. 5 (c). In this case, since the character string following this REM statement is a comment to help understand the contents of the program such as remarks, there is no grammatical restriction on this character string. Further, as shown in FIG. 5 (b), the third type is composed of a line number, additional information 12 indicated by the [*] symbol, and a character string following this additional information 12. The additional information 12 indicated by this [*] symbol is this additional information.
Like the character string following the REM statement, it has a function of allowing a character string following 12 without any grammatical constraint. Therefore, the character string following the additional information 12 may be any combination of characters. The line number is a combination of numbers 1 to 9 and is set in the range of 1 to 65535.

Therefore, when the general statement of the program data of FIG. 5A includes a statement that has not been set in the information processing apparatus, it is determined that the corresponding program data is not valid and an error exists. Specifically, the general statement of the program data input from the external device 6 is [ATT] as shown in FIG.
When the general statement having the same meaning defined in the information processing device is [AT], the program data of this one-line sentence is determined to be an error.

An error will also occur if the arguments following the general statement do not satisfy the grammatical constraints mentioned above.

FIG. 3 is a flow chart showing specific operations of the program data input analysis means 1 and the error forced correction means 2.

In FIG. 3, when the flow chart is started, one line of program data is read from the I / O driver 7 in S (step) 1. Next, the validity of the program data read in S2 is determined by the above-described method. When it is determined in S3 that the relevant program data is valid program data, the process proceeds to S4, and the relevant program data is stored in the program storage memory 5. As described above, the program storage memory 5 for one row of program data input from the external device 6
Since the loading process to is completed, it is confirmed in S5 that there is program data that has not been loaded.
Return to S1 and read the program data of the next line.

If it is determined that there is an error in S3, in S6,
After confirming that the program data is from the external device 6, the program data including the error is sent to the error forced correction means 2 in S7. The error compulsory correction means that has received the program data including the error is shown in FIG. 5 (b).
As shown in, the additional information 12 indicated by the [*] symbol is added to the space position between the line number and the general statement in the relevant program data. Then, in S9, the relevant program data having the additional information 12 attached to the predetermined position is re-input to the program data input analysis means 1.

The program data input analysis means 1 to which the program data with the additional information 12 is input from the error compulsory correction means 2 determines the validity of the corresponding program data in S2. Since the additional information 12 is added this time, even if there is an error in the general statement including the error following the additional information 12, the statent following the additional information 12 is regarded as a character string indicating a message only. , The corresponding program data is determined to be valid. Therefore, the program data with this additional information 12 is written in the program storage memory 5 in S4.

In this way, the program data of each line forming the program input from the external device 6 is finally written in the program storage memory 5 regardless of the presence or absence of an error.

Next, a procedure for editing and creating the program stored in the program storage memory 5 by using the program edit creating means 3 will be described.

FIG. 4 is a flowchart showing a process for searching the error program data in the program stored in the program storage memory 5 by using the error program data searching device 3e in the program editing / creating device 3. First, in Q1,
The search line in the program storage memory 5 is initialized to the top line. Next, in Q2, if it is confirmed that the search line does not exceed the last line of the program, the program data for the corresponding one line is read. After checking the line number of the program data read in Q3, move the check position to the next character position following the line number. In Q4, move the check position to a character position other than space.

Then, in Q5, it is checked whether or not the additional information 12 indicated by the character [*] symbol exists at the corresponding check position. If the additional information 12 exists, an error exists in the relevant program data, and the line number is displayed in the empty area of the display unit 9. After advancing the search line one line, the process returns to Q2. If the additional information 12 is not detected in Q5, the relevant program data is valid program data from the beginning, so nothing is done and the process directly returns to Q2.

When the search line exceeds the last line of the program in Q2, the search process of the error program data is completed, so it is checked in Q8 whether the line number is displayed on the display unit 9.
If the line number is not displayed, a message such as "no load error" is displayed.

In this way, by activating the error program data retrieval means 4e, it is possible to retrieve the program data including the error in the program already written in the program storage memory 5.

Next, in the program data editing means 3b, for example, one line of program data to which the additional information 12 of the program displayed on the display 9 by the program display means 3a is added is changed by the data input from the input device 6. It has a function of changing (correcting) and a function of inputting new program data from the input device 6 and changing (correcting) the program stored in the program storage memory 5 as necessary.

Further, the program output means 3c sends the program data of each line corrected or newly inserted by the program data editing means 3b to the program data input analysis means 1 to check that the relevant program data does not include an error. It has a function to reconfirm.

Specifically, during correction of program data or new input operation, input information is displayed on the display 9 each time the input device is operated. The operator confirms the display contents, and if there is no error in the corrected or input program data, the operator operates the execution key (return key) to write it in the program storage memory 5. Then, the program data is input to the program data input analysis means 1 as described above.

The program data cursor moving means 3d is used for the line number of the program data displayed on the display 9 by the operator,
Used to specify each character in the program data.

In this way, when the correct program is registered in the program storage memory 5 by the program editing / creating means 3, the program executing means 4 of FIG. 1 is activated.

The program executing means 4 has a function of reading out the program stored in the program storage memory 5 line by line and executing the program. Then, in the execution process, when the program data including the error that has been forgotten to be corrected remains, the program data with the additional information 12 exists, so the program data with the additional information 12 is added. The program operation is stopped when it is read. Then, the error line and a message indicating the cause of the error are displayed on the display unit 9.

That is, the program executing means 4 has a double safety assurance function for detecting forgetting to correct the program data which has become an error when the program is loaded, in addition to the normal program executing function.

If the information processing method and the information processing apparatus configured as described above are used, the external device 1 such as a host computer is used.
Even if program data including a statement not defined in the information processing device is input from the program storage memory, the program data including this error is attached with specific additional information 12 that regards this program data as one message. Written to 5.

Therefore, unlike the conventional apparatus, even if an error is detected in the program loading process, the program loading process is not interrupted. Therefore, even if the program is not compatible, the whole program can be loaded, and most of it can be used as it is by editing it later.

Further, it becomes possible to retrieve the program data of each line written in the program storage memory 5 using the additional information 12. Therefore, the error contained in the program data is not corrected at the time of loading the program but can be once stored in the program storage memory 5, and then the program data including the error can be collectively retrieved to be corrected. Therefore, the operator does not need to be present during the program loading period. In addition, since the error can be surely corrected later, the reliability of the program executed after the error correction can be improved.

[Effects of the Invention] As described above, in the information processing method and the information processing apparatus of the present invention, when an error is detected in the program data of each input line, the error is detected at a predetermined position in the program data including this error. An error is compulsorily corrected by indicating that this program data contains an error and adding specific additional information that regards this program data as one message. Therefore, even if program data containing an error is mixed in the program input from the outside, the program can be continuously loaded without the intervention of the operator. Further, by using the additional information, the error can be retrieved and corrected later. Therefore, the operation can be performed with the correct program, and the burden on the operator can be significantly reduced.
