Abstract

PURPOSE:To prevent the break of files, by providing a table, through which a file name is used to index a volume name or a volume name is used to index a file name, and displaying that different files are disignated to the same volume and allowing the operator to discriminate whether this designation should be permitted or not. CONSTITUTION:Index tables I1 and I2 are used to index file names F1-Fn and volume numbers V1-Vn, and a control statement for files F1-Fn of a file device 3 is inputted to a magnetic tape 4 through a control card 1. By indication DISP in the last field of the control statement, information indicating that new files to be registered are designated to the same volume is added if they are designated to the same volume. Cards are read 2, and files F1-Fn are transferred successively to an area 10 of a memory 6, and a discriminating part 8 uses the table I2 to check whether files are designated to the same volume or not, and the check result is displayed on a device 12 through a controlling part 7. Thus, the operator discriminates whether the processing should be permitted or not, and he indicates transfer continuation or cancel by a keyboand 13 to prevent the break of files.

Description

[Detailed Description of the Invention] The present invention! When using magnetic tape as a file medium.Regarding the file catalog registration method.

When registering a file in a catalog* (registering information related to the location of the file), the conventional method has a means to check for errors in which the same file is registered twice. This is because there is no means to check IK9 registered in the same volume specified by a file.

If a magnetic tape with different files specified for the same size is used from the beginning of the magnetic tape for outputting another O file, the i* file that has already been registered will be deleted. However, there is a drawback that the catalog registration is not deleted and remains. Therefore, when creating a catalog f#, it is necessary to input (*request) to register different files in the same volume. If we adopt a method that leaves it up to the judge.

This makes it possible to prevent different files from being registered in the same policy.

The present invention has focused on the above points, and aims to provide a file catalog registration method that prevents errors in file catalog registration. In a catalog registration method having a register in which a file name and a volume name corresponding to the file are registered by inputting a control statement including specified data, the volume name is indexed by the file name. 1st
a second index table for indexing the file by the volume name; an f stage for determining whether the volume name of the designated data is appropriate; and displaying the results of the determining means. and a display means, and when different FIs are specified in the same polyme in the specification data of the FI & record control statement, the information of the same polyme is displayed on the display section. This is a file cataloging method.

Hereinafter, nine aspects of the present invention will be explained with reference to the drawings. The drawings are six block diagrams illustrating one embodiment of the present invention.

1 is a control card, 2 is a card reader, 3 is a 7-isle storage, 4 is a magnetic tape, 5 is an escape device, 6 is a memory, 7 is a control section, 8 is a discrimination section, and 9 is an abnormality processing section.

! The registered file name and information related to its location (volume number, etc.) are registered in the register 11 on the i1 page.

1, and I are tables for checking double registration of files registered in this registration 1111. 0 Index table I is a table that uses file names F, ~Fn as indexes, and index table II is a table that uses volume names as indexes. This is a table whose index is Mu, V, and Mu, and the latter index table, ■, has been newly retired.

In the drawing, file ゛(F,

When the catalog is referenced and stored, the control statement is manually written using the control card l. At the end of Mk of the control statement of control card l, DISP = (NIC

This means that the files registered in i11' have the same polygon.

Check by. If there are files that specify the same volume, the control section 7 outputs and displays the file name on the display section 12. When this display tjL9 operator accepts this same volume designation (not -), he presses the Gt key on the keyboard 1300. The OK decoder GO sent to the keyboard 1300 causes the control unit 7

Activate Ihada-dokoro #A section 9 to end the Ihaku.

As described above, the present invention allows magnetic tape to be used as a button 17. - In the system used as a system, when files are in the same volume, the information specified in the -m is displayed on the display section, and the suitability of the information is left to the operator's judgment.S This allows the retention period of the file to be set. This has the advantage of preventing file damage in cases where it is difficult to do so.
