Description

[Detailed Description of the Invention] [Summary] In a conversion method that converts character string data including a character code and a control code into a character data string to which an address on the screen is added, a new line code is added in correspondence with the character code. When a line feed code is detected in the above character string data, this line feed code is added to the character code before this line feed code, and unnecessary line feeds are removed by placing the line feed code at the beginning of the line. I tried not to get caught.

[Industrial application field]

An address that indicates the horizontal and vertical coordinates that specify the position on the screen in order to display character string data (hereinafter referred to as text data) consisting of a control code including character codes and line feed codes on a display or printer. This article relates to a method of converting the text into character data added to each character code.

[Conventional technology]

Text data consists of character codes, which are the minimum data necessary to display character information on the screen, and control codes such as line feed codes, and such text data can be displayed on the screen in the desired display format. In order to display the text on the screen, the position on the screen is added to each character code that makes up this text data to convert it into a character data string for screen display.

[Problem that the invention seeks to solve]

In this text data, line feed codes that indicate intentional line breaks are also placed in the code string of the text data regardless of the display position on the screen, so the codes that make up this text data are predetermined. When converting into a character data string for screen display, a line feed code is placed at the beginning of the line, and a line feed is performed at the beginning of the line, resulting in a blank line on the screen.

In other words, Fig. 2(d) shows an example when the text data shown in Fig. 2 (al) is arranged sequentially at the character display positions on the screen. Then, the next line feed code R becomes the starting position of the next line, this line is broken at the beginning by this line feed code R, and the next character code Ck is displayed on the next line, and in the end, this line feed code is placed at the beginning of the line. The located line will be displayed as a blank line on the display or as a result of printing.

Measures to solve problem C] In addition to the address on the screen that is added to the character code, a line feed code can be added, so that when a line feed code is detected in character string data, the previous character Added a newline code to the code and converted it to a character data string.

To specifically explain the principle of the present invention with reference to FIG.
a) is text data, fbl is a character data string converted from this text data according to the present invention, and (81
In the text data shown in the figure, C1, C2...
. . cj, Ck . . . Cn are character codes, and a line feed code R is inserted between the character codes Cj and Ck.

This text data is converted to generate the character data string shown in the fbl diagram, and the value X on the horizontal axis and the value on the vertical axis on the screen that displays the character specified by this character code corresponds to each character code. y is added to these character codes, and according to the present invention, a line feed code indicating a line feed can be added corresponding to these character codes.

Then, this line feed code is added to the character code Cj that precedes this line feed code R in the text data, and this line feed code is further deleted from the character data string to perform character filling.

[For production]

According to the present invention, when data converted to a character data string as shown in FIG. When the line feed code R is added corresponding to this character code, a line feed is performed, but a line feed is not added to the character code Ck located at the beginning of the next line because no line feed code is added. , so there are no blank lines.

〔Example〕

FIG. 2 shows an embodiment of the present invention, in which input text data is applied to a buffer memory 1 that latches one character code or control code, and a line feed code detector 2. When no code is detected, the character code is stored in the character code storage area of the memory 3 such as the first-in-first-out memory from the buffer memory, and at the same time the processor 4 calculates the display position of the character specified by this character code.
The position X on the horizontal axis and the position y on the vertical axis on the screen are stored in the position storage area.

When the line feed code detector 2 detects a line feed code in the text data, the line feed code is stored in the line feed code storage area of the memory 3, but at this time, the line feed code before this line feed code delayed by l code period is stored in the buffer memory. Since the character code and its display position are stored in the character code storage area and position storage area, this line feed code will be stored corresponding to the character code before this line feed code in the text data. .

In this embodiment, when a line feed code is detected, the buffer memory 1 is cleared and this line feed code is deleted from the character code string of text data, and the existence of this line feed code is also transmitted to the processor 4 to It is configured so that no error occurs in the calculation of the display position.

In addition, this memory has a color signal storage area so that a color instruction signal from the processor is stored in the memory 3 corresponding to each character in order to specify the color of the characters displayed on the display. A memory is further provided, from which character codes, display positions, line feed codes, and color signals are simultaneously read out and used for display on a display or the like.

It should be noted that the present invention is not limited to the above-described processing by hardware, but it is clear that it can also be executed by processing by software.

〔Effect of the invention〕

According to the present invention, even if a line feed code in text data comes to the beginning of a line on the display screen, an unnecessary line break is not performed, so the screen on the display or the printed screen becomes significantly easier to see, and it can also be misunderstood. It is possible to achieve a special effect in which such a situation does not occur.
