Abstract

PROBLEM TO BE SOLVED: To relate two desired files and select those two files in a lump. SOLUTION: Respective files are stored on a floppy disk(FD), and each file has attribute information and serial number information as its header information. When the file name and attribute of a file to be generated newly are inputted (step S1), the inputted file name and attributes are stored in a RAM (step S2), and files having attributes matching the inputted attribute are attracted from the FD (steps S3-S9) and each of the extracted files are stored in a RAM (steps S10-S13).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file control device for controlling a plurality of files.

[0002]

2. Description of the Related Art Conventionally, in a document processing device such as a word processor, a created document is saved as a document file in an external storage device such as a floppy disk and can be recalled later.

In such a document processing apparatus, when a large document is created, it may be partially saved as a plurality of files. Further, depending on the type of the document processing device, it is not possible to create a document of a predetermined amount or more due to the capacity of the document data area of the internal memory. Therefore, it is inevitable that the documents will be created separately and different Some have to be saved as files.

When one of the plurality of files saved in this way is called, the desired file name is selected from the list of file names.

[0005]

However, when one document is divided into a plurality of files and saved, it takes time to know how the respective files are connected, and the connection is difficult to understand. There was a problem.

[0006] The reason for this is that when a file is called, only a list of file names is displayed, and there is no information indicating the connection of files.

An object of the present invention is to associate two desired files with each other so that the two files can be collectively selected.

[0008]

The means of the present invention sets a concatenation setting means for setting concatenation of two files and a concatenated file name common to the two files for which concatenation is set by the concatenation setting means. It is characterized by further comprising: a file name setting means; and a management means for connecting and managing the two files for which the connection is set by the connection setting means with the connection file name set by the file name setting means.

Therefore, two desired files can be associated with each other and the two files can be collectively selected.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram showing a configuration of a file control device of an embodiment, and a reference numeral 11 is a CPU that controls the entire control. 12 is an IPL (initial program loading) program executed by the CPU II,
The ROM stores IOCS (input / output control system) programs, character patterns, and the like. 13 is a program area 13a, a buffer memory frame area 13b, and a work area 1
3c, document data area 13d, file name / attribute area 1
3e, etc. is a RAM.

Reference numeral 14 is a keyboard for inputting data, and 15 is a keyboard control section for controlling the keyboard 14. Although not shown in the drawing, the keyboard 14 has a "table of contents creation" key for instructing the creation of a table of contents file as described later.

Reference numeral 16 is a video RAM (VRAM) in which a document data to be displayed on a display unit 17 such as a CRT is developed, and 18 is a display control unit for controlling the display unit 17 according to the display data of the VRAM 16. Reference numeral 19 is a printer for printing out document data, and 20 is a RAM 1
3 is a printer control unit that outputs the document data in 3 to the printer 19. Reference numeral 21 is a floppy disk (FD) as an external storage device for storing a document file, a table of contents file to be described later, and 22 is an external storage control unit for accessing the disk 21.

Next, the operation of the file controller having such a configuration will be described. It is assumed that documents such as those shown in FIGS. 2A to 2F are stored in the FD 21 with file names such as “description 1”, “description 2”, and the like. In this case, in each document, the index “·” is attached to the item that should be the item of the table of contents. Further, in each file, attribute information and serial number information are stored as header information.

Here, by operating the "create table of contents" key of the keyboard 14, the flowchart of FIG. 3 is started and a table of contents file is created. That is, first, the file name (the name of the newly created table of contents file, for example, "Chapter 1"
Etc.) and attributes (attributes indicating the target for creating a table of contents file) are input (step S1). For example, "Chapter 1" is input as the file name and "Chapter 1" is input as the attribute. The input file name and attribute are stored in the file name / attribute area 13e of the RAM 13 (step S
2).

When the file name and the attribute are designated in this way, one file is read from the FD 21 (step S3). Then, the attribute information of the called file is compared with the attribute information stored in the file name / attribute area 13e of the RAM 13 (step S4). If the attributes match (step S5), the file name of the file, The attribute information and serial number information are written in the buffer memory area 13b of the RAM 13 (step S6). This operation is repeated for all files (step S
7). As a result, as shown in FIG. 4, in the buffer memory area 13b, the file name, the attribute information of the file having the attribute of "Chapter 1" input in the above step SI as the attribute indicating the target of creating the table of contents file, Serial number information is stored.

When the above operation is performed for all files in this way, the information stored in the buffer memory area 13b of the RAM 13 is rearranged in the order of serial numbers (step S8). Next, one file is read from the FD 21 according to the file names arranged in the order of serial numbers (step S9), and the item with the index "." Is searched from the read file (step S10).
Then, the retrieved item is stored in the work area 13c of the RAM 13 in association with the file name of the currently read file (step S11). Such processing is repeated for all the files specified by the information stored in the buffer memory area 13b (step S12). By repeating such a process, as shown in FIG.
The searched item and the file name of the file including the item are stored in association with each other.

When the processing for the last file with the serial number is completed, the work area 1 of the RAM 13 is completed.
The contents of 3c are stored in the FD2 as a table of contents file with the file name (for example, "Chapter 1") input in step S1.
1 (step S13).

When the table-of-contents file is created in this way, the table-of-contents file is automatically read from the FD 21 and displayed on the display unit 17. Therefore, only by designating an item, the file in which the item exists. Can be easily realized by reading out and displaying.

Further, FIG. 5B shows the above step S1.
Then, as the newly created table of contents file name, "Chapter 2"
Indicates a table of contents file created when "Chapter 2" is input as an attribute indicating the target of creating a table of contents file.

[0020]

According to the present invention, the concatenation of two files is set, the concatenated file name common to the two files is set, and the two files are concatenated and managed by the concatenated file name. The two files to be associated can be associated with each other and the two files can be collectively selected.
