DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device having a document processing function, for example,
The present invention relates to a document display method that enables a document processing device to display character data of arbitrary lines within a document all at once.

[Conventional technology]

Conventionally, regarding document display in a document processing device, it is common to display character data sequentially based on page and line information of the document.

[Problem to be solved by the invention]

The above-mentioned prior art can display character data only in the order of pages and lines.

Therefore, when related or noteworthy descriptions are scattered throughout the document, in order to create a document while referring to them, there is a limit to the number of lines that can be displayed at one time, so scrolling, etc. There was a problem in that it was necessary to frequently perform key operations to change the display position of the document.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document display method that makes it possible to collectively display character data in any line within a document.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a first storage means for storing page and line information of a document to be displayed on a display device, and a page and line information stored in the first storage means. and a first control means for reading character data corresponding to the read page and line and displaying the character data corresponding to the read page and line on the display device. means for instructing information on whether or not to display the information, and a second means for storing the instructed content.
A storage means is provided.

Further, a second control means is provided for rewriting the contents stored in the first storage means based on the contents stored in the second storage means.

The second control means stores page and line information for the knee row in the first storage means for a row whose contents stored in the second storage means is information indicating that the content is to be displayed on the display device. The contents of the first storage means are rewritten by writing to the above.

The first storage means and the second storage means can be realized, for example, as a table provided in a data memory of hardware constituting the information processing apparatus.

For example, in the former case, the page number and line number of the document to be displayed are set to 1.
The latter is a display line management table that stores data indicating whether or not the lap line is to be displayed on the display device for each line of the document.

Further, the instruction means may, for example, provide a display/non-display key on the keyboard of the hardware constituting the information processing apparatus, position the cursor on the line to be specified, and display/hide the display/hide key.
This can be achieved by pressing the hidden key.

Further, the first control means and the second control means can be realized, for example, by a CPU of hardware constituting the information processing apparatus executing a control program. This control program is stored, for example, in a program memory of hardware that constitutes the information processing device.

It goes without saying that the present invention can be configured as part of the functions of an information processing device such as a personal computer or workstation that has a document processing function, but is particularly suitable for document processing such as a word processor that exclusively creates and edits documents. Effective when applied to equipment.

[Effect]

The first control means reads page numbers and line numbers of the document written in the first storage means (screen management table), and displays character data corresponding to the read page numbers and line numbers on the display device. indicate.

When the non-display key is input, the instruction means detects the page number and line number at the coordinates where the cursor is located, and stores the detected page number and line number in the second storage means (display line management table). The instruction means rewrites the information corresponding to the line number to information indicating that it is not displayed.Furthermore, when the display key is input, the instruction means
The page number and line number of the coordinates where the cursor is located and the page number and line number of the coordinates immediately below the coordinates where the cursor is located are detected, and the two detected page numbers and rows are displayed in the display line management table. Rewrite the information corresponding to the page number and line number between the numbers with information indicating that they are to be displayed.

The second control means rewrites the contents of the screen rental table based on the contents of the display line management table. In other words, for the row that the contents of the display row management table above indicate to display, the page number and row number of the knee row,
Write to the above screen management table.

Since the first control means displays the character data on the display device based on the rewritten screen management table, the character data could only be displayed based on the order of pages and lines of the document. Character data from any line in a document can be displayed all at once.

FIG. 4 is a diagram showing the structure of a table used in this embodiment.

In FIG. 4, 401 is a screen management table, and 402 is a display line management table.

The screen management table 401 stores page numbers and line numbers of documents to be displayed on the display device 105, and has the number of records equal to the number of lines that can be displayed on the screen.

The display line management table 402 stores data indicating whether or not to display each line of all pages in a document.

Screen management table 401 and display line management table 40
2 are both stored in the data memory 104.

Next, the operation of this embodiment will be explained.

FIG. 2 is a flowchart showing the operation of this embodiment.

When the hide key is input from the input device 101, the CPU 402 detects the page number and line number of the document from the coordinates where the cursor is located on the screen of the display device 105, and stores them in the data memory 104. Temporarily memorize (step 201).

Subsequently, the CPU 102 detects the corresponding storage position in the display line management table 402 from the page number and line number stored in the data memory 104 in step 201 (step 202).

Next, the CPU 102 rewrites the data in the display line management table 402 (step 203).
This is to write data indicating the person who is not to be displayed into the storage location detected in step 202.

Next, the CPU 102 sets the writing position of the screen management table 401 to the top position of the table (step 204).
, After step 205, the screen management table 401 is rewritten.

First, the CPU 102 reads the page number and line number stored in the screen management table 401 from the writing position in the screen management table 401 (step 205).

Next, the CPU 102 detects the corresponding storage position of the display line management table 402 from the page number and line number read in step 205, and sets it as the read position of the display line management table 402. (Step 206).

In step 207, the CPU 102 reads data from the read position of the display line management table 402 and determines whether to display the data.

If the data read in step 207 indicates that the data is not to be displayed, the CPU 102 performs the process in step 209, and if the data read out in step 207 is data that indicates that the data is to be displayed, the CPU 102 executes the process in step 208 before performing the process in step 209. I do.

In step 20g, the CPU 102 performs step 206
