JPS63245738A - Automatic correcting system for data item with undefined program - Google Patents

Abstract

PURPOSE:To execute efficient debugging work by automatically correcting an error considered due to a miss of a partial character in an item into a similar reserved word or a data definition item in the analysis of a source program. CONSTITUTION:A syntax error correcting processor 25 selects a vocabulary the most close to an undefined system vocabulary from information in a text line having an error stored in an error text storing file 13 and a system vocabu lary stored in a system vocabulary storing file 12, and when a decision ratio is more than a fixed value, the text is corrected by data in the file 12 and the corrected text is stored in a corrected text storing file 15. If the decision ratio is less than the fixed value, the text is stored in an uncorrectable text storing file 16. Then, a text replacing processor 27 corrects data in a text stor ing file 11 based on the information of the files 15, 16 and stores the corrected data in a corrected source program text storing file 17.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an automatic correction method for program undefined data items;
In particular, it relates to a method for automatically correcting program undefined data items when a source program is analyzed by a compiler.

[Conventional technology]

Traditionally, when a compiler analyzes a source program,
The compiler performs a syntax check based on reserved words owned by the compiler and data definition items declared in the source program, and outputs messages regarding items that appear other than those as undefined items. Therefore, even if the message is a misspelling, the operator checks the message at the peak of the season, re-corrects the source program, and compiles it again.

[Problem that the invention seeks to solve]

With the conventional method described above, simple mistakes (such as misspellings)
Even so, it is necessary to perform the same work over and over again, and there is a problem in that efficiency and operability are poor in debugging work.

An object of the present invention is to automatically correct some characters in an item that are considered to be incorrect when analyzing a source program to a similar reserved word or data definition item, thereby making debugging work more efficient. The object of the present invention is to provide an automatic correction method for program-undefined data items.

[Means for solving problems]

The automatic correction method for program undefined data items of the present invention includes a syntax analysis processing means for extracting undefined items of the program in program analysis processing, and defining the program undefined items extracted from the syntax analysis processing means as system terms. an error correction processing means for extracting an optimum value from the data area name, a text replacement means for replacing the optimum value extracted from the error correction processing means in a text, and an error state of the source program replaced by the text replacement means. and an error state determination processing means for analyzing the error state.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. In the figure, a text storage file 11. is used as an external storage device. System terminology storage file 12.

have. Further, as processing devices, a syntax analysis processing device 21, an error state determination processing device 22. Program data area name storage processing device 23. Error text storage processing device 24. Syntax error correction processing device 25° Data definition error correction processing device 26. It is configured to include a text replacement processing device 27 and an end processing device 28.

In the above configuration, the text storage file 11 is a file that temporarily stores the loaded source text program 10, and the text data stored in this file is used as the original data when correcting the text using automatically corrected text lines. The used and modified text data is stored in the modified source program text storage file 17. The system terminology storage file 12 is a file in which reserved words possessed by the compiler and terms defined by the system are stored. The error text storage file 13 is a file in which text lines with errors and error contents are stored, and corrections are made to this data. The data area name storage file 14 is a file that stores data area names defined by the source program, and is referenced when correcting text with an error. The modified text storage file 15 stores text modified by the modification process. The unmodifiable text storage file 16 stores text lines for which modification processing was attempted but were determined to be unmodifiable. Furthermore, the syntax analysis processing device 21 performs a grammatical check on the source program and sends the error text to the error state determination processing device 22, and also sends the data area name defined in the program via the program data area name storage processing device 23. It is stored in the data area name storage file 14. The error state determination processing device 22 examines the error line and its detailed contents from the sent error text, stores the information in an error text storage file via the error text storage processing device 24, and
It is determined whether the error text is a corrected source text that has already been processed by the present invention, and if it has been corrected, the details of the error before correction, the correction location, the correction content, and further correction are performed via the final processing device 28. Subsequent error information and the like are output as an analysis result list 30. The syntax error correction processing device 25 uses the error text storage file 13
Pattern matching is performed with the contents of the system terminology storage file 12 as error information stored in the system terminology, and it is determined whether correction is possible based on the specified discrimination rate.If correctable, the error location is corrected based on the system terminology. It is a device that performs The data definition error correction processing device 26 performs pattern matching on the error portions that could not be corrected by the syntax error correction processing device 25 with the data area names registered in the data area name storage file 14, and achieves a specified discrimination rate. This device determines whether the error can be corrected based on the data area name, and if it is correctable, corrects the error location based on the data area name. The text replacement processing device 27 is a device that changes the source program stored in the text storage file 11 by using modified text lines, and stores the modified text in the modified source program text storage file 17 as modified text.

Next, to proceed with the explanation of the operation shown in FIG. 1, first, the source text program 10 is stored in the text storage file 11. Next, the syntax analysis processing device 21 performs a grammar check. At that time, the data area name declared in the program is transferred to the program area name storage file 14 by the program data area name storage processing device 23.
is stored in On the other hand, the source program whose syntax has been checked by the syntax analysis processing device 21 is judged by the error state determination processing device 22 as to whether it is corrected text data or raw text data. For example, the analysis results are output by the termination processing device 28 as an analysis result list 30. In this case, the system processing ends above, but if it is raw text data, the error text storage processing device 24 processes only the text line with the error into the error text storage file 13.
is stored in Then, the syntax error correction processing unit 25
Information on the text line with the error stored in the error text storage file 13 and system terminology storage file 1
Detect undefined system terms from the system terms in 2.
Furthermore, the system term closest to this undefined system term is selected, and if the discrimination rate is above a certain value, the text is corrected using the data in the system term file 13 and stored in the corrected text storage file 15. . If the discrimination rate is below a certain value, this text data is compared with the data stored in the data area name storage file 14 by the data definition error correction processing device 26, and is compared with the closest data as described above. If the discrimination rate between is equal to or higher than a certain value, the data is corrected to the data in the data area name storage file 14 and stored in the corrected text storage file 15. If the discrimination rate is below a certain value, the text is stored in the unmodifiable text storage file 16 as an unmodifiable text. Next, the text replacement processing device 27 executes the modified text storage file 15. After modifying the data in the text storage file 11 based on the information in the non-modifiable text storage file 16, the data is stored as modified text data in the modified source program text storage file 17, and the syntax analysis processing device 21 is again controlled. It is passed and processed repeatedly.

Note that the above discrimination rate may simply be a ratio between a predetermined number of characters and the number of matching characters.

[Effects of the Invention] As explained in detail above, the present invention extracts undefined items in a source program and automatically replaces them with what is considered to be the optimal value when analyzing a source program in a program analysis processing device. Since simple entry errors are automatically corrected, there is an effect that the manual correction work of the source program can be greatly reduced.
