In a document processing system equipped with a display section, a keyboard section, and a display section, when a document file is transferred between a media section and a document memory, position information in the document file of document data to be displayed on the display section is stored. The present invention relates to a document switching control method in a document processing system in which document data is added and transferred, and document data according to the position information can be displayed on a display unit.

[Conventional technology and problems]

FIG. 1 is a diagram showing an outline of the configuration of a document processing system, and FIG. 2 is a diagram explaining a conventional document switching control method. In the figure, 1 is the processor section and 2 is the processor section.
CRT display section, 3 is keyboard section,
4 represents a media section, and M represents a document memory.

In FIG. 1, the processor section 1 is a so-called I/
Document memory (storage area) which is a logical control unit excluding O and stores the document being handled or created.
have. The CRT display section 2 displays some document data on the document memory M, and the keyboard section 3 is used to input document data and command information (commands) necessary for document handling and editing. A media section 4 is a recording medium for storing a group of document files, such as a floppy disk, hard disk, bubble, etc., which is read and written by the processor section 1. One document file is
The document 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 the document file is being handled by the processor section 1, it is in the main memory;
The contents of the document file change one after another depending on the operation (this document file is referred to as the current document file), but at this time the same file in the media 4 remains unchanged.
The current document file is sufficiently larger than the display window (such as the screen of a CRT display) or window, and while the document is being handled, the position of the window can be moved up or down,
Editing processing is performed so that the required line is projected approximately in the center.Generally, when creating and referencing documents, work is often done while referring to and writing in multiple documents at the same time. For example, refer to a certain part of document A, then add an item to a certain part of document B, return to the original reference part of document A, look at the next information, and then add an item to a certain part of document B. The work progresses by adding to the previously added section, and so on. here,
Operations on the addition section or reference section involve adjusting the specific window position of those document files, and when proceeding with the operation from document A reference to document B addition or vice versa, switching of the current document file is required. comes in. This process of switching the current document file is divided into two phases: registration of the current document file in the media, deletion of the old version, and loading of the document file to be switched onto the main memory (document memory).

In conventional document processing systems, when a document file to be switched is loaded from the media onto the main memory by switching the current document file, the document file is normally displayed from the beginning unconditionally. Therefore, as shown in FIG. 2, when the current document file is once stored ( ) from the document memory M to the media section 4 and then reproduced ( ) from the media section 4 to the document memory M again, scrolling or It was necessary to give a command to change the display position and search for the window that was previously referenced. When a document has been stored for some time or is accessed frequently, it is quite a burden for the operator to remember exactly the line or character position that was last processed, and it is generally Returning it to working condition requires quite complex operations and mental labor.

[Purpose of the invention]

The present invention is based on the above considerations, and includes:
The work process of the document that was previously being manipulated is automatically reproduced as the document file is loaded into main memory, reducing operational burden and improving processing efficiency. The purpose of this invention is to provide a document switching control method in a document processing system that can perform the following steps.

[Structure of the invention]

For this purpose, the document switching control method in the document processing system of the present invention has a media section that stores a plurality of document files, and one document memory area on the main memory.
A document comprising a processor section that takes in one document file and executes document creation work, a keyboard section that inputs document data and command information to the processor section, and a display section that displays part of the document data in the document memory. In the processing system, the processor unit includes a display position holding unit that holds position information on the document memory of document data to be displayed on the display unit, and a display position holding unit that holds position information on the document memory of document data to be displayed on the display unit; A display control mechanism that controls displaying the above document data on the display section, a document file transfer mechanism that transfers document files between the media section and the document memory, and input from the keyboard section. The document file transfer mechanism includes a main control mechanism that performs overall control based on document data and command information, and the document file transfer mechanism transfers the document file between the media section and the document memory. When storing the above document file in the media section, the position information held in the display position holding means is also stored together with the document file in the media section, and the document file is stored from the media section onto the document memory. When importing the document file, the document file is imported into the document memory, and the position information is also imported and set 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]

Embodiments 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.
The figure is a diagram illustrating the flow of document file switching display control. In FIG. 3, 1 to 4 indicate those corresponding to FIG. 1, 5 is the main control mechanism,
6 is a document file read/write mechanism, 7 is a display control mechanism, 8 is a document memory, 9 is a register, 1
0 and 11 indicate document files.

In the present invention, by specifying document switching (giving one command), first, the document that has been processed so far (current document file) is displayed, the display position (for example, the cursor position), and the position information of the window position on the document are displayed. The newly specified document is stored in the media section along with the newly specified document to be processed into the main memory.
Then, window settings are performed for the imported document based on the position information of the display position and window position. FIG. 3 shows the configuration of one embodiment of the present invention having these functions.

In FIG. 3, the main control mechanism 1 uses the data received from the keyboard section 3 to store a document memory 8,
It updates the document data being handled and its display data through the register 9, display control mechanism 7, etc., updates the document file data in the media section 4 through the document file read/write mechanism 6, and realizes the contents of the operator's instructions. It is. The document file read/write mechanism 6 receives an instruction to transfer a document file between the media section 4 and the document memory 8 from the main control mechanism 6, and executes the instruction. Upon receiving a 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, X and Y are the contents of the register 9 at the time of the display request, and the register 9 is the content of the display data stored in the document memory 8 that is used when the display control mechanism 7 displays the document data on the CRT display section 2. It holds location information. As mentioned above, the document memory 8 is a storage area on the main memory that stores the document being handled or created, and is usually much larger than the displayable area controlled by the display control mechanism 7. When document data is input from the keyboard section 3, the data is set in the corresponding memory area after the cursor position through the main control mechanism 5. On the other hand, a plurality of document files 10 and 11 are stored in the media section 4, and the document files 10 and 11 contain the document data at the time when the file was last stored, as well as the content (position) of the register 9 at the time of storage. information) has been copied.

Next, document file switching processing will be explained. First, it is assumed that the document file A is loaded into the document memory 8 and is to be edited. At this point, the main control mechanism 5 inputs a message from the keyboard section 3 that means "switch the current document to file B." Upon receiving the command, the main control mechanism 5 divides into the following steps,
It executes commands using the lower control mechanism under its control.

The document file read/write mechanism 6 is requested to write the current document file. As a result, the document file read/write mechanism 6
Check whether there is an old version in the media section 4 (that is, if the current document file A is already registered, that file), and if it exists, transfer it to the media section 4.
Delete from inside (in this case, document file 1
0). Then, the new version of the current document file A is taken out from the document memory 8, registered in the media 4, and written out. At this time, the contents of register 9 are also stored.

Furthermore, a document file read/write mechanism 6
Instructs to read new document file B. As a result, the document file read/write mechanism 6 finds the document file 11 on the medium 4 and first takes in the document body and sets it in the document memory 8. Thereafter, the document position information X, Y is also fetched and set in the register 9.

Next, a display instruction is given to the display control mechanism 7. As a result, the display control mechanism 7 takes out the contents X and Y from the register 9 and displays the first display data.
Document memory 8 whose character corresponds to the beginning of the Xth line
Find out at the address above. Then, N lines of document data from that address are displayed. At this time, the cursor is set to the Y-th character from the beginning of the displayed N lines.

When the above display is completed, register 9
The address of the current character (the character on which the cursor is placed) of the current document file is stored in preparation for the next data or command from the keyboard section 3.

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

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

When a request for document A is received as the first file, document A is loaded from the media section 4 into the document memory 8 as the current document file, and window settings are performed based on window position information x _A and y _A. In other words, the window position that is set immediately after loading is set by aiming the first line of the screen at line _xA of the document file, and counting the cursor position on the screen from the character at the top left of the screen.
y Align to _{the A} -th character position.

The loaded current document file is used as a handling file, and various operations are applied to it.
The window position also changes rapidly.

If it becomes necessary to write to a part of document B at window positions x' _A and y' _A , a document switching command is issued and document B is requested as a new document.

By the document switching command, the latest document A (current document file) on the document memory 8 that has undergone various changes is stored in the media 4, and at the same time, the old document file Aold that has been in the media 4 is stored.
will be deleted.

Next, the requested document file B is stored in the document memory 8.
from within the media 4, and perform window settings based on the window position information x _B and y _B in the same manner as 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 B is performed at window position x′ _B ,
The process ends at _y'B , and a document switching command to document A is issued in order to restart the work from the same part of document A that was handled last time.

Thereafter, the document switching command is executed in the same manner as described above, and the window setting for document A is realized in the state immediately before the previous document switching command was executed.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, even if the operator forgets what kind of work process was performed on the document that was the target of the previous operation, the state of the screen position and cursor position can be changed. Since the information is reproduced, it can be recalled easily and document creation work can be facilitated. In addition, since the information for screen reproduction is recorded in a file within the media, it is important to leave the system by turning off the power or temporarily giving the right to use the system to someone else.
Even if you resume work after a period of time,
All you need to remember is the file name. in this way,
According to the present invention, it is possible to reduce the operational burden of document switching and significantly improve work efficiency and operability in document creation work in which a large number of documents are referred to here and there and filled in at the same time. can.
