Abstract

PURPOSE:To reduce the burden of the users and to simplify the correction of data by converting automatically the data attribute and setting it to a data record. CONSTITUTION:When the contents of the data record of a data file 2-1 are corrected, a main program 1-1 reads the relevant data record out of the file and sends it to a transfer buffer 11 to call out a data correction program 3. Then the program 3 inputs a correction parameter 4 including the correction data described in the correction start position, the corrected data length and the prescribed data attribute and the converted data attribute through an input means 31. The parameter 4 is analyzed by an analyzing means 32, and the attribute of the corrected data is converted by an attribute converting means 33. Then the corrected data are set by a setting means 34 at the part equivalent to the length of the corrected data and distant from the correction start position of the data record included in the transfer buffer 11. The program 1-1 rewrites the corrected data record in the original part of the file 2-1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data correction device for correcting the contents of data records in a data file.

[0002]

2. Description of the Related Art Generally, in an information processing system, various data files having different file organization methods exist.
Further, the data stored in the data record of the data file also contains data having various data attributes such as characters and binary-coded decimal numbers. Therefore, when the contents of the data record of the data file are modified, conventionally, the function of reading and writing the data record according to the file organization method corresponding to each data file, and the modification separately prepared by the user Create a data correction program with the function of setting correction data in the data record read from the data file according to the correction information including the correction data including the location information and the data attribute that match the data attribute of the data record to be corrected. , The data file is corrected using this data correction program.

[0003]

Although it is possible to correct the data record of the data file by the method described above, there are the following problems.

Since the user needs to create modified data having the same data attribute as the data attribute of the data record to be modified, the data cannot be modified without some knowledge and experience. Also, the working time becomes longer.

Since a data correction program having a correction data setting function in addition to a read / write function must be created for each data file, the scale of the program increases as the number of data files increases.

The present invention has been made in view of the above circumstances, and an object thereof is to enable a person with little knowledge or experience to easily modify a data file and to provide a function of actually modifying the data. The main purpose is to enable the correction unit to be shared to correct a plurality of data files.

[0007]

In order to achieve the above-mentioned object, the present invention is a data correction device for correcting the contents of a data record of a data file, and a correction unit for correcting the data record and a correction target from the data file. And one or a plurality of upper parts for writing back the corrected data record to the data file, the correction start position and the correction data length. An input means for inputting a correction parameter including correction data described by a predetermined data attribute and a converted data attribute, and an analyzing means for analyzing the correction parameter input by the input means,
Attribute conversion means for converting the attribute of the data, and based on the analysis result by the analysis means, from the correction start position of the data record read by the upper part to the portion for the correction data length, by the attribute conversion means Setting means for setting the correction data obtained by converting the data attribute of the correction data into the converted data attribute.

[0008]

In the data correction device of the present invention, when the content of the data record of a certain data file is to be corrected, the upper part created according to the file organization method of the data file is the data record to be corrected from that data file. The data is read out and passed to the correction unit. In the correction unit, the input means inputs the correction parameter including the correction start position, the correction data length, the correction data described by the predetermined data attribute, and the converted data attribute, and analyzes it. The means analyzes the input correction parameter, and the setting means, based on the analysis result, changes the data attribute of the correction data to the portion corresponding to the correction data length from the correction start position of the data record by the attribute conversion means. The modified data obtained by converting the above to the converted data attribute is set. Then, the upper part writes back the data record corrected by the correction part to the original part of the data file.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of a data correction device of the present invention is a data file 2-
1, 2-2, a main program 1-1 provided for the data file 2-1, a main program 1-2 provided for the data file 2-2, and a plurality of these main programs It is composed of a data correction program 3 commonly provided for 1-1 and 1-2, and a correction parameter 4 given to this data correction program 3.

The main program 1-1 is a data file 2-
The main program 1-2 constitutes the upper part that performs the main processing when the data is modified, and the main program 1-2 constitutes the upper part that performs the main processing when the data of the data file 2-2 is modified, and passes each inside. It has buffers 11 and 12.

The data correction program 3 is held in the delivery buffer 11 or the delivery buffer 12 of the calling main program 1-1 or main program 1-2 by being called from the main program 1-1 or main program 1-2. A correction unit for making a correction based on the correction parameter 4 on the data record being recorded is configured.

The data correction program 3 includes an input means 31 for inputting the correction parameter 4 and the correction parameter 4.
Analysis unit 32 for analyzing the data, attribute conversion unit 33 for converting the attribute of the data, and an instruction from the correction start position indicated by the correction parameter 4 of the correction target data record based on the analysis result by the analysis unit 32 with the same parameter. Setting means 34 for setting the correction data obtained by converting the data attribute of the correction data of the correction parameter 4 by the attribute conversion means 33 into the data attribute after conversion designated by the parameter in the portion corresponding to the generated data length. ing.

FIG. 2 shows an example of the correction parameter 4 for one record. In the figure, P = 25, LEN = 4, V
= 2, DAT = 246 is a set of parameters for one correction point, P = 40, LEN = 5, V = 1, DAT =
CITY1 is a set of parameters for different correction points,
E indicates the end of the correction parameter.

Here, the value of P is the transfer buffers 11 and 1.
2 is a parameter indicating the beginning of a correction location by the number of leading bytes from 2, the value of LEN is a parameter indicating how many bytes length from that location is modified, DAT is correction data described by a predetermined data attribute, V The value of indicates the data attribute after conversion.

FIG. 3 shows an example of what data attribute of the correction data described in the correction parameter 4 is converted into correction data according to the value of V. As shown in the figure, when V = 1, the original data attribute of the modified data is converted to the data attribute of “character”, and when V = 2, it is converted to the data attribute of “decimal number”, V = 3
In the case of 4 and 5, binary evolution 1 defined by Kobol 1
COMP-1, COMP-2, COMP- which are 0-base numbers
Converted to a data attribute of 3.

Here, the original data attribute of the correction data is uniquely determined by the system that created the correction parameter 4. That is, the code obtained when the numeric key or character key of the keyboard is pressed has the data attribute unique to the input system, and the data attribute is not always the data attribute set in the data record to be corrected. Although not done, in the present invention, the correction data is created by the data attribute itself when the user inputs it from the keyboard or the like, and is automatically converted into the corresponding data attribute when setting it in the data record. This significantly reduces the burden on the user.

FIG. 4 is a flow chart showing a processing example of the main programs 1-1 and 1-2, FIG. 5 is a flow chart showing a processing example of the data correction program 3, and FIG. 6 is a view showing a correction example of the data record. The operation of this embodiment will be described below with reference to the drawings.

For example, consider modifying a data record in the data file 2-1 as follows. 4 bytes starting from the 25th byte from the beginning 24 in decimal
Correct to 6. The 5th byte from the 40th byte from the beginning is the character
Correct to 1 ”.

In such a case, the user creates the correction parameter 4 as shown in FIG.
Start -1.

As shown in FIG. 4, the started main program 1-1 first opens the data file 2-1 (S1), and reads the data record to be corrected after the head portion of the internal transfer buffer 11. (S2). Then, the data correction program 3 is called (S3).

The data correction program 3 first uses the input means 31 to set a set of parameters (P = 25, LEN = 4, V = 2, DAT = 24) of the correction parameter 4 shown in FIG.
6) is input (S11), and the analysis unit 32 causes the correction position,
The correction length, correction data, and data attributes after conversion are analyzed (S12). At this time, for example, P = ○○ 25 (○
Even if it is "blank", it is not an error and it is recognized as P = 25 so that the user can input parameters in a free format.

Next, the data correction program 3 converts the data attribute of the correction data "246" by the attribute conversion means 33 into a decimal data attribute according to V = 2 (S1).
3). Then, according to P = 25 and LEN = 4, the modified data “246” after conversion is set in 4 bytes starting from the 25th byte from the beginning of the delivery buffer 11 (S1).
4). Here, if the corrected data length after conversion is shorter or longer than the byte length of the setting destination, the standard data transfer processing rule is followed. That is, when the length is short, the data is right-justified and 0 is put in the remaining portion. On the contrary, when the length is long, the lower digit is given priority and set.

When the data correction program 3 finishes the correction at one place, it judges whether or not all the correction parameters 4 for the data record have been processed (S15), and if the processing is completed, the operation is ended. If the processing has not been completed, the process returns to step S11 and the above-described operation is repeated. Therefore, in the case of the correction parameter 4 in FIG. 2, next (P = 40,
LEN = 5, V = 1, DAT = CITY1) is processed, and then E is detected and the operation is ended.

By the above-described operation being performed by the data modification program 3, the content of the data record to be modified stored in the delivery buffer 11 is modified to the modification content as shown in FIG. 6, for example.

When control is returned from the data correction program 3 to the main program 1-1, the corrected data record in the transfer buffer 11 is written back to the original location of the data file 2-1 (S4). Then, it is determined whether or not all the data records to be modified have been processed (S5). If all the data records to be corrected have not been processed, the process returns to the process S2 to repeat the above process, and if all have been processed, the data file 2-
1 is closed (S6), and the process ends.

In the case where a plurality of data records in the data file 2-1 are to be corrected and the correction contents are different, the correction is made in the same order as the data records read by the main program 1-1. The parameters 4 are arranged side by side, and the data correction program 3 is configured to input the correction parameter for the next one record each time it is called.

[0028]

According to the data correction device of the present invention described above, the following effects can be obtained.

The user does not need to create the correction data with the data attributes at the time of setting in the data file, but simply inputs the correction data composed of numbers, characters, etc. from the keyboard to create the correction parameters including the correction data. All you have to do is make it easy for beginners to modify the data.

Since the correction part is shared by a plurality of upper parts,
The overall scale becomes smaller.

The modification contents can be dealt with by modifying the modification parameters and there is no need to modify the program.
