Abstract

PURPOSE:To recognize data which is finally inputted and to prevent the unmatching of a data file at the time of restoration after power is disconnected by storing the number of reading data and a final write address at the time of inputting and processing data. CONSTITUTION:At the time of inputting data, at first, the number of valid records 33 is referred, and a data group (one slip data) in the data file 35, which is shown by the number of the valid records 33 are displayed in a display so as to wait for recognition. An input guidance is displayed in the display after a recognized input is accepted. When data is inputted, error check is executed, input data is written in the data file 35 shown next to the number of the valid records. Then, the number of the valid records is added and updated and the input guidance is displayed again in the display so as to wait for input.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an entry data file management method, and in particular, to verifying the validity of data when a computer power is cut off, which may occur during data input. Entries to keep - related to data file management methods.

[Conventional technology]

The conventional entry-data file management method of this type is as follows:
For example, when writing slip data to a file device, the length of the data to be written per slip and the file device depend on the usage efficiency of the file device, writing time, ease of use of the data written to the file device, etc. Although the lengths of the slip codes do not match and each slip is composed of a plurality of records, the number of valid records and the number of writable records in the file device are managed by the operating system of the computer.

[Problem to be solved by the invention]

In the conventional entry data management method described above, when one slip is stored in multiple records on a file device, after one slip is inputted on the input device, the computer is turned off while it is being stored in the file device. If a disconnection occurs, an error will occur in the number of valid records in the file device managed by the operating system and the number of inputted slips, and the document data may be partially stored in the file device. Sometimes this happens, and the form for restarting data entry becomes unclear.

[Means to solve the problem]

The entry-data file management method of the present invention includes an input means for checking the validity of data input by an input device in a data processing device and detecting an error, and a notification when an error is detected by the input means. a display means for displaying the message on the data display device; a means for writing the valid data at a position next to the last address of the valid data stored in the data file device for storing the valid data; Update the valid data last address to the address where the data was written,
and management information update means for storing the management information in the management information file device.

〔Example〕

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

FIG. 1 shows an embodiment of the present invention.
One embodiment of the present invention is a system comprising a data processing device 11, an input device 16, a display device 17, a data file device 18, and a management information file device 19 connected thereto. The data processing device 11 includes a display unit 12,
It has an input section 13, a data writing section 14, and a management information updating section 15, and realizes the functions of these sections.

The input device 16 is used to input nine characters, symbols, etc. (data), and is used to notify the input unit 13 of the input data. This input unit 13 inspects the validity (for example, check digit check) of the input data notified from the input device 16, and if invalid data is detected, a message to that effect is displayed on the display unit 12. Notify. The data writing section 14 writes valid input data into the data file device 19 from the position next to the valid data final address indicating section. The management information update section 15 updates the valid data final address instruction section to the final address of the data file device 19 written by the data writing section 14, and the 0 display section 12, which is to be written, If a valid record exists in the data file device indicated by the valid data final address, the message is displayed and notified to the display device 17 as the final input data. The data file device 18 is a device that stores valid data. The management information file 19 is stored in the data file device 1
This is a device that stores the final address of valid data within 8.

FIG. 2 shows a flowchart in this embodiment, and the third
The figure shows the file relationship of the device according to one embodiment of the present invention.6 This embodiment is a management information file, as shown in FIG. have.

Next, the operation of this embodiment will be explained using FIG. 3. First, in step 21, the number of valid records 33 is referred to, and it is determined whether or not there is already input data. When the number of valid records 33 is greater than or equal to zero, the number of valid records is 33.
The data group (one slip data) in the data file 35 shown by is displayed on the display and waits for confirmation by the operator.

This process makes it easy to confirm the final input data. After confirming the input, in step 24, data input guidance is displayed on the display. - On the other hand, when the number of valid records 33 is zero, data input guidance is displayed on the display in step 24. In step 25, the operator inputs data or inputs a termination instruction.

When a termination instruction is input, the operation is terminated. Step 27 checks the validity of the input data, and if an error is detected, an error message is displayed on the display (step 20), and the process goes to step 25.
If no error is detected, the process goes to the next step 28. In step 28, the input data is written to the data file 35 shown after the number of valid records 33 (+1st record).

In step 29, the number of valid records 33 is updated. If one input data consists of n data file records, n is added to the number of valid records 33. After the update, the process returns to step 24 again.

〔Effect of the invention〕

As explained above, the present invention manages the number of data input units after a power failure occurs during data input processing, so that when restarting, the last input data can be confirmed and the data file The above data also has the effect of preventing fraud from occurring.
