Abstract

PURPOSE:To improve the processing efficiency by regenerating the state of a screen position or a cursor position in response to the loading of a document file onto a main memory to represent the working process of a document which was the object in the previous operation. CONSTITUTION:A display control mechanism 7 receives a display request from a main control mechanism 5 and displays document data on the X-th to N-th rows of a document memory 8. Then a cursor is displayed at the position of the Y-th character. Both X and Y show the contents of a register 9 obtained when a display is requested. The register 9 holds the position information on the memory 8 for the display data which the document data is displayed at a display part 2. When the document data is supplied from a keyboard part 3, the data is set to the corresponding memory area at and after the cursor position through the mechanism 5. A medium part 4 stores document files 10 and 11, and the document data obtained files 10 and 11 are finally stored, and copied together with the contents of the register 9, i.e., the position information obtained in a store mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention has a media unit that stores a plurality of document files, and a document memory area on a main memory that imports one document file to execute document creation work. In a document processing system that includes a processor section, a keyboard section, and a display section, when the document file is transferred between the media section and the document memory, the position of the document data to be displayed on the display section in the document file is determined. The present invention relates to a document switching control method in a document processing system in which information is also added and transferred, and document data according to the position information can be displayed on a display unit.

[Prior art and problems]

Figure 1 shows an overview of the configuration of the document processing system.
The figure is a diagram illustrating a conventional document switching control method. In the figure, 11d is a processor section, 2 is a CRT display section, 3 is a keyboard section, 4 is a media section, and M is a document memory.

In FIG. 1, a processor section 1 is a so-called logic control section excluding I10, and has a document memory (storage area) for storing a document being handled or created. The CRT display section 2 displays part of the document data on the document memory M, and the keyboard section 3 is used to input the document data and command information (commands) necessary for document handling and editing.

The media section 4 is a recording medium that stores a group of document files, and includes a floppy Δ disk, a node disk, a bubble, etc., and is read and written by the processor section 1. One document file is loaded into the document memory M on the main memory of the processor section 1, and the text is written, deleted, or modified through the processing mechanism of the processor section 1.

Therefore, when a document file is handled by the processor section 1, its contents change one after another depending on the operations performed on the main memory (this document file is referred to as the current document file). The same file inside has not changed. The current document file can be saved in a display window (such as the screen of a CRT display) or a window (Wi
When handling a large number of documents, the window position is moved up and down so that the required line is displayed approximately in the center, and editing processing is performed.

Generally, when creating and referencing documents, work is often done while referring to and writing on multiple documents at the same time. For example, you can refer to a part of document A, then add an item to the part of document B, go back to the original reference to the document, look at the next information, and then add an item to the part of document B. The work progresses by adding to the additional section, and so on. Here, operations on the additional section and the reference section involve adjusting the specific window position of those document files, and also the operation of the document A.
When proceeding from reference to document B addition or vice versa, the task of switching the current document file is required. This process of switching the current document file is divided into two phases: (1) registering the current document file in the medium and deleting the old version; and (2) loading the document file to be switched onto the main memory (illiterate memory).

In conventional document processing systems, when the document file to be switched is loaded from the media to the main memory during the switching operation of the current document file, the document file is usually displayed unconditionally from the beginning. . Therefore, as shown in FIG.
When reproducing (■) from the document memory M, it is necessary to search for the previously referenced window by giving a command to scroll or change the display position from the beginning. When a document has been stored for some time or is accessed frequently, it is a burden for the operator to remember exactly the line or character position last processed; Returning to the original state requires many complex operations and mental labor.

[Purpose of the invention]

The present invention is based on the above considerations, and is based on the ability to mechanically reproduce the working process of a previously manipulated document as the document file is loaded onto the main memory. The object of the present invention is to provide a document switching control method in a document processing system that can reduce operational burden and improve processing efficiency.

[Structure of the invention]

To this end, the document switching control method in the document processing system of the present invention includes a media section that stores a plurality of document files, a processor section that inputs one document file into a document memory area on the main memory and executes document creation work. A keyboard section for inputting document data and command information to the processor section.

and a document processing system comprising a display unit that displays part of the document data in the document memory, wherein the processor unit is configured to maintain a display position that holds position information on the document memory of the document data to be displayed on the display unit. means, a display control mechanism for controlling display of document data on the document memory on the display section according to position information held in the display position holding means, transfer of document files between the media section and the document memory; The document file transfer mechanism has a main control mechanism that performs overall control based on the document data and command information input from the keyboard section. When transferring a document file to and from the document memory, when storing the document file on the document memory in the media section, and when importing the document file from the display position media section together with the document file, K is.

The device is configured to import the document file into the document memory and also import the position information and set it in the display position holding means to mechanically reproduce the display in the previous state of use. It is characterized by:

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a diagram showing the configuration of one embodiment of the present invention, and FIG. 4 is a diagram explaining the flow of document file switching display control. In FIG. 3, ■ to 4 indicate those corresponding to FIG. 1, and 5 is the main control mechanism.

Reference numeral 6 indicates a document file read/write mechanism, 7 a display control mechanism, 8 a document memory, and 9 registers %10 and 11 a document file.

The present invention allows you to specify one document switching (by giving one command). First, the document that has been processed so far (current document file) is moved to one display position (for example, Karnl position)% of the window's document position. It is stored in the media section along with the position information, and the newly specified document is subjected to import processing into the main memory.

The third embodiment shows the configuration of an embodiment of the present invention that has the function of setting the window for the imported document based on the position information of the display position and the window position.
It is a diagram.

In FIG. 3, the main control mechanism 1 updates the document data being handled and its display data through the document memory 8% register 9, the display control mechanism 7, etc. based on the data received from the keyboard section 3, and The document file data in the media section 4 is updated through the file read/write mechanism 6 to realize the contents of the operator's instructions. The document file read/write mechanism 6 receives an instruction from the main control mechanism 6 to transfer a document file between the media section 4 and the document memory 8, and executes the instruction.

In response to the display request from the main control mechanism 5, the display control mechanism 7 displays the document data from the The control is performed so that it is displayed at the Y-th character position. Here, register 9 at the time of the X and Y display request
The contents of the register 9 are as follows:
The document memory 8, which holds position information on the document memory 8 of display data used when displaying document data on the display section 2, stores documents that are being handled or created. This is a storage area on the main memory that stores , and is much larger than the displayable area normally controlled by the display control mechanism 7. When one document data is inputted from the keyboard section 3, the data is set in the corresponding memory area after the Kanle position through the main control mechanism 5. On the other hand, the media section 4 contains multiple document file formats.
゜11 is stored, and the document file 10. ．． 11, the contents (position information) of the register 9 at the time of storage are copied together with the document data when the file was last stored.

Next, document file switching processing will be explained. First, it is assumed that the document file AdE has been loaded into the document memory 8 and is to be edited, and the control mechanism 5 selects the command [Switch the current document to file B] from the keyboard section 3. When the main control mechanism 5 receives the IB order meaning 1
It divides into the following steps and executes the commands using the lower control mechanism under its control.

■ Request the document file read/write mechanism 6 to write the current document file. As a result, the document file read/write mechanism 6 reads the old version (
In other words, if the current document file A is already registered, that file)
Check whether there is a
.

Then, the new version of the current document file A is taken out from document memo 1-8, registered in media 4, and written out.

At this time, the contents of register 9 are also stored.

(2) Furthermore, it instructs the one-document file read/write mechanism 6 to read the new document file B. As a result, the 1-document file read/write mechanism 6 locates the document file 11 on the medium 4, and first takes in the 1-document body and sets it in the document memory 8. After that, the location information of the document (X,
Y) is also fetched and set in register 9.

(2) Next, a display instruction is given to the display control mechanism 7. As a result, the display control mechanism 7 reads the contents X from the register 9,
It is known that the first character of Yi fetch 1 display data is located at the address on the document memory 8 corresponding to the beginning of the Xth line.

Then, N lines of document data from that address are displayed. At this time, the cursor moves from the beginning of the displayed N lines to Y
Set to half moon character.

■ When the display according to (■) above is completed, the register 9 is read, the address of the current character (the character where the input key is placed) of the current document file is stored, and it is prepared for the next data or command from the keyboard section 3. .

The value of register 9 is the display window movement command (scroll command)
etc., through the main control unit 5. Also,
When inputting one character of document data, etc., it is set (rewritten) to the address of the document memory 8 at the current character position.
The value of Y in register 9 is incremented by 1 and a display command is given.

FIG. 4 shows the flow of document file switching display control.

■ Upon receiving a request for document A as the first file,
Load the sentence gA from the media unit 4 into the document memory 8 as the current document file, and set the window based on the window position information Z,. Aim the line at line ZA of the document file, and position the cursor on the screen at the character position of 9 months, counting from the character at the top left of the screen.

■ Various operations are applied to the loaded current document file as a handling file, and the window position changes rapidly.

(2) If it becomes necessary to write part of document B at window position λ, yA', then a document switching command is issued and document B is requested as a new document.

■ Due to the document switching command, the latest document A (current document file) on the document memory 8, which has not undergone any changes, is stored in the medium 4, and at the same time, the old document file Aold that had been in the medium 4 is stored. will be deleted.

(2) Next, the requested document file B is loaded onto the civilized memory 8 from within the medium 4, and window settings are performed based on the window position information 4*j7B in the same manner as in (2) described above.

■ Then, the required operation is performed on document B.

At this point, document B becomes the current document file.

■ The operation on document BK ends at window position χd,9, and a document switching command to document 1 A is issued in order to restart the work on the previously handled document from the same location.

(2) Thereafter, the document switching command is executed in the same manner as in (2) and (2) described above, and the window setting for document A is realized in the state immediately before the statement 1: switching command according to the previous (2) is executed.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, even if the operator has forgotten what kind of work process the document that was the target of operation was in before, the state of the screen position and the carnage position can be checked. Since the information is reproduced, it can be recalled easily and document creation work can be facilitated. Unfortunately, the information that cannot be reproduced on the screen is recorded in a file on the media, so please turn off the power, give up the right to use the system to someone else, leave the system, wait for a while, and then restart the work. Even if you want to restart, you only need to remember the file name. Thus, according to the present invention,
In document creation work in which a large number of documents are referred to here and there at the same time and parts are filled in, the operational burden of document switching can be reduced and work efficiency and operability can be greatly improved.
