JPH0546604A - Determining system for line starting digit position in document editor - Google Patents

Abstract

PURPOSE:To easily input a document by moving the position of a cursor of a next line to the same position as the preceding starting digit position in the case that the input of a character code overflows the line end of a document text. CONSTITUTION:In a document editor, the character code is inputted on the cursor displayed by a cursor display means 1 by a key input means 2. That character code is set in a document buffer B by a buffer control means 3, and the character code is displayed on a terminal display screen C by a picture display means 4. In the case that the character code is a line end, a line starting digit determining means 5 compares the starting digit position of a present line with the starting digit position of the line inputted immediately before, and when the present line is the continuous line of the first one, it makes the digit position obtained by subtracting '1' from the starting digit position of the present line having become the line end the starting digit position of the next line. Besides, in the case that this line having become the line end is the continuous line, the starting digit position of the next line is made the starting position of the present line having become the line end. A cursor changing means 6 displays the cursor on the same digit position as the changed starting ditit position of the next line.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing system for a document editor, and more particularly to a line start column position determining system.

[0002]

2. Description of the Related Art In a conventional line start column position determination method using a document editor, a user operates a cursor movement key to determine a line start column position.

[0003]

In the above-described line start column position determining method for the document editor, the user operates the cursor movement key to determine the start column position of the line to be input. However, there is a drawback that the user needs many key operations.

[0004]

A line start column position determining method in a document editor according to the present invention is a cursor display means for displaying a cursor indicating a character input position on a terminal screen, and a user depresses a key on a keyboard. The key input means for inputting the character code generated by the pressed key, the screen display means for displaying the character code input by the key input means on the terminal screen, and the character code input by the key input means When the character code input exceeds the line end of the document text and the buffer management means to store in the document buffer, the start column position of the current line is compared with the start column position of the line entered immediately before to determine the continuation line. A terminal start position determining means for determining the starting position of the next line and a terminal screen for key input at the position of the position determined by the line starting position determination means. And executes a cursor change means for changing the cursor.

Embodiments of the present invention will now be described with reference to the drawings.

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

Cursor display means 1 of the document editor shown in FIG. 1 displays a cursor at a digit position where a character is to be input.

The key input means 2 allows the user to enter the keyboard K
Input the character code generated by pressing the key and press the character code by the buffer management means 3 in the document buffer B.
Set to.

The screen display means 4 displays the character code input by the key input means 2 on the terminal screen C.

When the character code set in the document buffer B is the end of line (step 5)
1) Compare the start column position of the current line of the document buffer B with the start column position of the line just input (step 52), and when the current line is the first continuation line, start the current line which is the end of the line. The digit position obtained by subtracting 1 from the digit position is set as the start digit position of the next line (step 53). If the line at the end of the line is a continuation line, the start column position of the next line in the document buffer B is the start column position of the current line at the line end (step 54).

The cursor changing means 6 displays the cursor on the terminal screen C at the same column position as the starting column position of the next line of the changed document buffer B.

As described above, when the input of the character code exceeds the end of the line of the document text, the start column position of the current line and the start column position of the line input immediately before are compared to determine the continuation line. By determining the starting column position of the next line, the cursor can be displayed at that position and the document can be easily input.

[0013]

As described above, according to the present invention, when the input of the character code exceeds the line end of the document text,
By comparing the start column position of the current line with the start column position of the line entered immediately before to determine the continuation line and determining the start column position of the next line, the cursor is displayed at that position and the document is displayed. It is possible to easily input the.

Claims (2)

[Claims] 1. A cursor display means for displaying a cursor indicating a character input position on a terminal screen, and a key input means for inputting a character code generated by the depressed key when a user depresses a key on the keyboard. A screen display means for displaying the character code input by the key input means on the terminal screen; a buffer management means for storing the character code input by the key input means in a document buffer; When the line end is exceeded, a line start column position determining means for comparing the start column position of the current line and the start column position of the line input immediately before to determine the continuation line and determining the start column position of the next line And cursor changing means for changing the cursor on the terminal screen so that a key input can be performed at the column position determined by the line start column position determining means. Row start digit position determination method in the book editor. 2. When the character code set in the document buffer is the end of the line, the line start column position determining means compares the start column position of the current line of the document buffer with the start column position of the line just input, When the current line is the first continuation line, the column position obtained by subtracting 1 from the start column position of the current line that has become the end of the line is set as the start column position of the next line, and when this line that became the end of the line is the continuation line, the above document 2. The line starting column position determining method in the document editor according to claim 1, wherein the starting column position of the next line of the buffer is set to the starting column position of the current line which is the end of the line.
