Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a text screen display control method for displaying text on a screen display device.

Conventional technology The conventional method for displaying text on a screen is to display a continuous text area that fits on one screen from the beginning to the end of the line, and then move that screen between the beginning and end of the line. A control system was used that allowed the entire line of text to be seen.

Problem to be Solved by the Invention However, in the conventional text screen display control method described above, when the maximum number of characters in one line of text is greater than the maximum number of characters in seven lines on the screen, the next line after a certain line The disadvantage is that it is inconvenient to see the connections between texts because the terminal Δ portion of the previous line disappears from the screen when you try to see the beginning of the line.

The present invention has been made in view of the above-mentioned conventional circumstances.
SUMMARY OF THE INVENTION It is therefore an object of the present invention to overcome the above-mentioned drawbacks inherent in the prior art.

Means for Solving the Problems In order to achieve the above object, the text screen display control method according to the present invention specifies a text buffer storage means for storing text and a partial area of the text to be displayed on the screen. Display area designation storage means for storing information; display area designation means for designating a text display area; text/line character count storage means for indicating the maximum number of characters in one line of the text buffer; storage means for storing the number of characters per line on the display screen, storage means for storing the number of lines on the screen for indicating the number of lines on the display screen, display area designation, number of characters on 7 lines of text, screen 1
Create a screen display image of seven screens of text based on the number of line characters and the number of screen own lines, and if the area of text to be displayed is not one continuous area on the text buffer, 2
screen display image creation means for creating a screen display image by connecting two separate continuous text regions one after the other;
and screen display means for sending a screen display image to a screen display device for display.

EXAMPLE Hereinafter, a preferred embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention includes a text buffer storage means 1, a text/line character number storage means], a screen/line character number storage means 3, a screen white display line number storage means I1
The one-screen display image creation means j is composed of one-screen display means 6, display area designation means, and display area designation storage means t.

Referring to Figure 1, screen display image creation means! teeth,
Continuous text display possibility Semi-fixed section 11 This consists of a screen buffer front section creation section, a screen buffer rear section creation section n1, and an overall screen buffer creation section.

Referring to FIG. 3, the screen display means 6 is composed of a screen display image input section 3/ and a screen display image output section 3.

Next, the operation of the present invention will be explained with reference to the drawings.

Referring to Figures 2 and 3, you can see how to create a screen display image! (by the display area specifying means 7) specified display area specifying storage means L, number of characters per line of text storage means J, and screen 1
A screen display image is created in the screen buffer adder l by referring to the line character number storage means J and the screen white display line number storage means D, and is delivered to the screen display device B. At this time, the text continuous display possibility determination unit 1 selects the display start position (Xo, y (1) Q- and the text buffer 1 indicated by the contents of the text 1-line character storage means) indicated by the contents of the display area specification storage means j. Is it possible to create a screen display image on the screen buffer adder/top by extracting a continuous area of text from the display start position lI2 based on the maximum number of characters in a line and the number of characters per line on the screen indicated by the contents of the screen character count storage unit 3? The possibility of continuous display is impossible if a, <!, otherwise it is possible. Here, a is the display start position X in the line.
. This is the number of characters from to the end of the line, that is, the number of characters in seven lines of text, and the abscissa coordinate I0 of the display start position. If continuous display is possible, the overall screen buffer creation department review is displayed in the text buffer.The number of characters per screen line horizontally from the display start position axis.
A screen display image is created by copying the continuous area of the number of vertically displayed white lines on the screen to the screen buffer. If continuous display is not possible, first, the screen buffer front creation unit 3 creates a continuous area from the display start position "oeYO)II" horizontally to the end of the screen and vertically in a continuous area of the number of display lines on the screen. This corresponds to the diagonal lined area in the upper left of the figure.

Next, the face buffer rear creation department Kohiro moves a continuous area from the ('*yO) position of the text buffer storage means l horizontally to the number of characters a2 and vertically to the screen circle display line number to the right rear part of the screen buffer 7. Copy. a2 is the number of characters per line on the screen 1 - (text 1
Line character count Display start position horizontal coordinate X. ). This is a copy of the diagonally shaded area on the upper right of Map No. 1.

FIG. 3 is a re-display of the creation of the screen display image in FIG. 4 with the text buffer endlessly hidden.

Referring to FIG. 3, the screen display image input section 31 is a screen display image creation means! Screen buffer 4 created by (
/ Input the above screen display image, edit it for the screen display device by going to the screen display image output section 3, and send it to the screen display device for display.

Display images on the screen will be explained with reference to FIGS. 1, 7, and S. Assume that text as shown in FIG. 6 is currently stored in the text buffer.

If you want to see from the end of the third line to the beginning of the first line in Figure 6, the conventional method would display the text area surrounded by the dashed line in Figure 6, then display the text area surrounded by the dashed line. It will be displayed by scrolling. FIG. 7 shows the change in the display screen at that time.

In this way, when the face display moves to the beginning of the line, it is difficult to see the part of the sentence that precedes the part of the sentence at the beginning of the line, making it inconvenient to grasp the connection between sentences. Recognize.

On the other hand, in the text screen control method of the present invention, since lines are displayed endlessly as in the faS diagram, it is easy to grasp the connections between sentences.

In this example, we have explained how to display lines endlessly by displaying the beginning of the line following the end of the line. There is also a method of displaying the beginning of . The screen display image in that case is as shown in FIG.

2. In Figure 2, the display start position is used as an example of specifying the display area, but of course it may be the center position or the final position of the screen display image, and the present invention includes both of them.

As described in detail, according to the present invention, by displaying text endlessly on the screen in a direction parallel to the lines, the end of one line and the beginning of the next line can be displayed on one screen, and Since it is displayed in a close area on the screen, even if one part of the text cannot be displayed on one screen, the effect is that the context of the text from the end of a line to the beginning of the next line can be easily grasped. It will be done.
