Abstract

PURPOSE:To dump out the contents of data including a wrong part due to a verifying error by setting freely a desired position to start a verifying operation and the verifying length between the sequential file and volume for execution of the verifying operation and outputting the position of the verifying error to a display device and a printer. CONSTITUTION:A floppy disk F or a hard disk E is provided together with a display device C, a keyboard D, a printer G, and a controller which controls these component parts. The controller sets the verifying start positions of two files to be verified and the verifying length with the input of a command, etc., of a user received via the keyboard D. Then the controller carries out the verifying operation. When a verifying error occurs, the data on the wrong part is added to the address of a relative position to the verifying start position. These added data and address are dumped out to the device C or the printer G. Thus it is possible to optionally set the verifying start position and the verifying length and also to verify two parts of the same file.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data verification device, and more particularly to a data verification device between (within) two sequential files or volumes.

[Conventional technology]

Conventional data verification devices scan sequential files or files from the beginning position between volumes.
Verification could only be performed on a volume basis, and it was not possible to arbitrarily set the verification start position within a file or volume, set the verification length arbitrarily, or verify two parts within the same file. .

[Problem to be solved by the invention]

The conventional data verification device described above can only verify files and volumes from the beginning of sequential files and volumes. Whether the existing data β are the same,
Furthermore, if you want to know the difference between these two pieces of data, there is a drawback that you have to dump out the parts containing these data parts from each file and visually inspect them.

[Means to solve the problem]

The helify device of the present invention is composed of a floppy disk or hard disk, a display device, a keyboard, and a control device for controlling the printer. In order to determine whether verification has been executed,
The control device has 2ffli! to be verified by the user inputting commands from the keyboard, etc. Set the verification start position and length of the two files, and execute the verification between the files using the set start position and length of the two files. If a verification error occurs, the data of the difference and the verification start will be executed. An address of the relative position from the position is added, and a dump is output to the display device or printer.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention.

Program H reads data from hard disk E and floppy disk F into areas A and B by manual input from keyboard 2, displays this on display WC, and outputs it to printer G.

Next, 11 examples of specific methods will be explained using FIGS. 2(21) to 3(c).

First, the program I reads the file C to be verified into verification areas A and B by input parameters and meter designations from the keyboard D.

This content is displayed on the display device C as a relative position from the beginning of 16 by I minutes as shown in FIG. Confirm and set command input from the keyboard as the two verification start positions as shown in FIG. 2(b).

Similarly, the length is also set as shown in FIG. 2(c).

Next, the positions of the two set positions on the two areas are stored and calculated programmatically, and the program executes verification for the set length between the two areas. When a verification error occurs, as shown in FIG. 3, the content including the relative position from the verification start position and the difference thereof is dumped and output to the display device and printer for 16 bytes.

〔Effect of the invention〕

As explained above, the present invention enables verification to be executed by setting the desired verification start position and length between (within) sequential files and volumes.
If a verification error occurs, the location will be displayed on the display device,
This has the advantage that it is possible to output the data to a printer and output the data contents including the different parts as a dump.

Claims (1)

[Claims] It consists of a floppy disk or hard disk, a display device, a keyboard, and a control device that controls the printer, and it determines where and how much of the data in a sequential file or volume on the floppy disk or hard disk is verified. Therefore, the control device sets the verification start position and length of the two files to be verified by the user's command input from the keyboard, and also uses the set start position and length of the two files. Verification between files is executed, and if a verification error occurs, the data of the difference and the address of the relative position from the verification start position are added and dumped to the display device or printer. Data verification device.
