[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indent control method for indenting the beginning position of a line of a text being created in a text processing apparatus to indent the text.

[0002]

2. Description of the Related Art Conventionally, when a document is processed such that a part of a sentence is indented while a series of sentences is being created, and then the indent is released and the indent is performed again, the indent amount is increased for each indent. It is set. Therefore, an indent amount different from the previously set indent amount is erroneously set, and a sentence is created with an unsightly arrangement.

Further, when the indent is released, the indent start point is moved to the beginning of the line or to the beginning of the indent point at the local point, and the cursor needs to be moved to the beginning of the line again. ,
Since it was just an instruction to release from the indent mode, it was necessary to give a line feed instruction or a cursor movement instruction after the mode was released.

[0004]

[Object] An object of the present invention is to provide an indent control system for a text processing device, which prevents an operation error and completes a beautifully created state.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a sentence produced in accordance with the present invention. Text A without indentation on one page
Is printed or displayed, the indent amount is set at the position b1, the sentence B is displayed or printed with the indentation left, and then the indent is released at the position b2 and a line feed is performed at the same time. As a result, the sentence C is printed or displayed without being indented. Then, when indenting and printing or displaying sentence D again, sentence B
Is indented by the same indent amount as. After the end of the sentence D, the indent is released and the line feed is performed at the position d1, and the sentence E is displayed or printed without indenting. In this way, after setting the indent amount l of the sentence D to be indented first, after that, the same indent amount d is set.
You can indent sentence D with. Therefore, sentences B and D are indented and a beautiful finish is obtained.

FIG. 2 is a block diagram of an embodiment of the present invention. The keyboard switch 1 includes a character input key 11 and a plurality of control keys 12 operated to instruct editing. The control key 12 includes an indent key 13 for instructing an indent, an indent cancel key 14 for canceling the indent control, and a function key 15 for instructing another control prior to the operation of the indent key 13. The function key 15 can be changed so as to perform other control operations in combination with other control keys. From this keyboard device 1, a character code corresponding to the operated character input key 11 or a related code and a code related to the control key 12 are generated and given to the processing circuit 2. The processing circuit 2 performs edit control according to the edit control program stored in the read-only memory 3. This editing control program includes a program for performing indent control according to the present invention. The random access memory 4 is input from the character input key 11,
A text buffer 41 that stores edited text data;
Indent buffer 4 that stores the indent amount indented by the indent key 13 for each setting instruction
2, a line character number counter 43 that counts the number of characters input in a line, and pointers 44 and 45 that are used when reading or writing data in the indent buffer 42.
And the flag 4 set when the function key 15 is operated.
7 and an area for storing other various buffer flags used for editing control.

The recording control of the printer 6 is performed by the control circuit 5, and the text data in the text buffer 41 is printed and recorded to create a text. A display device 8 such as a cathode ray display device is controlled by a display control circuit 7. The display control circuit 7 is a memory 71 for storing data to be displayed.
In the display memory 71, the data in the text buffer 41 and the characters input at the time of input by the character input key 11 are stored.

Next, the operation according to the operation of the keyboard device 1 will be briefly described. The text to be created is input by operating the character input keys 11. When indenting the sentence B as shown in FIG. 1, a desired indentation amount is obtained. A character or a space character is input, and then the indent key 13 is operated. In general,
Enter a space character for the left margin of horizontal writing. After that, when the sentence B is input, the position designated by the indent key 13 is set as the head of the line, and the sentence starts from this position.

When the sentence C is input again at the original position, that is, the left margin, the indentation cancel key 14 is operated at the position b2, the indentation is canceled, and a line feed is performed. Is printed or displayed. After that, in order to print or display the sentence D by indenting the same indent amount as the sentence D, the function key 15 is operated, and then the indent key 13 is operated. Therefore, the data indicating the previous indent amount is automatically read, and the sentence D is indented by the same indent amount and displayed or printed.

Referring to FIG. 3, in inputting a sentence, first, in step 100, the character input key 11 is operated, and then a character is input. The input character code is stored in the text buffer 41 in step 101, and the display memory 7 is stored in step 102.
1 is stored, so that the input character is displayed on the display device 8. In step 103, the content of the line character number counter 43 is incremented by 1 and counted. This operation is repeated each time each character is input, and the sentence buffer 41 shown in FIG. 8 enters the storage state.

One line of text is input, and the line character number counter 43 reaches the preset number of line characters, or the control key 12 is pressed.
When the line feed key included in is operated, step 110 of FIG. 5 is executed. Line feed data is sentence buffer 4
1 stored in step 111, and step 1
In 12, the line feed data is stored in the display memory 71, whereby the display device 8 displays a symbol indicating that a line feed should be made. In step 113, the line character number counter 43 is reset. In step 114, the data at the position corresponding to the content P1 of the pointer 44 of the indent buffer 42 is read, and it is determined whether the data is blank (Null). In the initial operation, the content P of the pointer 44
1 is blank, and "0" indicating blank is stored in the store area of the indent buffer 42 at the address I0 in the storage state shown in FIG. This generally allows the start of text creation to be entered from the left margin 1 in horizontal writing. Step 1 of FIG.
Since the content of the pointer 44 is blank at 14, the operation ends. In this way, the text buffer 41 stores the text as indicated by reference numeral 41a for displaying or printing the text A in FIG. This store area 41a
At the end of, the line feed key included in the control key 12 is operated.

The operation for indenting and operating the sentence B shown in FIG. 1 will be described (FIG. 6). The operator operates the space character key included in the control key 12 to input the space indicated by the reference mark SP in the store area 41b by the indent amount as shown in FIG. Then, the indent key 13 is operated. Step 13
Operation 5 is performed. In step 131, it is determined whether the content F of the flag 47 is "1". If not, the process proceeds to step 132, and the content of the line character number counter 43 is incremented by 1. In step 133, the indent code I is stored in the storage area 41c of the text buffer 41. In step 134, the symbol code of the indent is stored in the display memory 71, and the display device 8 displays that it is the indent. In step 135, the content P1 of the pointer 44 is incremented by 1. In step 136, the data of the line number counter 43 is stored in the corresponding position of the indent buffer 42, for example, I1 (see FIG. 9). In this embodiment, "2" is stored in the store area of the address I1. Then, the sentence is input starting from the indented start position. When a line feed instruction is issued, the operation of step 115 described above is executed. In step 114, the content P1 stored in the pointer 44 of the indent buffer 42 stores the position I1 and is not blank, so the procedure moves to step 115. As a result, the input position of the display memory 71 is skipped by the data stored in the indent buffer 42, or the blank I5 is stored.

To set the next sentence C to the left position without indenting as shown in FIG. 1, the indent releasing key 14 is operated at the indent releasing position b2. As a result, the operations after step 160 in FIG. 7 are executed. In step 161, the text buffer 41
The code corresponding to the indentation cancel key 14 is stored in, and the content P1 of the pointer 44 is incremented by 1 in step 162. In step 163, a blank is stored in the position corresponding to P1 of the indent buffer 13. In step 164, the display memory 71 stores the indent removal symbol code and the line feed code. Step 165
Then, the line character number counter 43 is reset. In this way, at the time of subsequent text input, the text C having the left margin at the beginning of the line is created without being skipped in step 115. The blank space skipped above is formed on each line of the sentence C.

An operation of indenting the sentence D by the indent amount as in the case of the sentence B will be described. It is assumed that the indent amount of the sentence D is 3, "3" is stored in the position I3 of the indent buffer 42, and the content P1 of the pointer 44 indicates the position I5. Prior to operating the indent key 13, the function key 15 is first operated. This causes the content F of the flag 47 to be set to logic "1" in step 121 as in step 120 of FIG. After that, when the indent key 13 is operated, the process moves from step 131 to step 140 in FIG.
The content P1 of the pointer 44 is transferred to the pointer 45 and becomes the content P2 of the pointer 45. Indent buffer 42
Whether the position I4 indicated by P1 of is blank is step 1
In step 142, the content P1 of the pointer 44 is decremented by 1 in step 142. Step 141
If a blank is detected in step 14,
Moving to 3, the content P2 of the pointer 45 is incremented by 1 and the position I5 is stored. P1 of indent buffer 12
The position I3 indicated by is transferred to the position I5 indicated by the content P2 of the pointer 45. Therefore, the data "3" is stored in the position I5 in step 143. The position I5 representing the content P2 of the pointer 45 is transferred to the pointer 44 in step 145 and then
In step 146, the line number counter 43 is set to a value corresponding to the data "3" at the position indicated by P1 in the indent buffer 42. In step 147, the text buffer 4
The space character corresponding to the line number buffer 43 and the indent code after that are stored in 1 and step 1
Similarly, the space character and the symbol code are stored in the display memory 71 at 48. Then, in step 149, the content of the flag 47 is reset, and the indent operation is completed. In this way, in the sentence buffer 41, the sentence B is stored in the store area 41, and the sentence C is stored.
After being stored in the store area 41F, the store area 41G
Three blanks are stored in. In the position I5 of the indent buffer 42, "3" is stored as in the position I3.
In this way, the indentation amounts of the sentence B and the sentence D are also "3", and it is impossible for the present invention to set the indentation amount erroneously as in the above-described prior art.

[0015]

As described above, according to the present invention, by operating the indent cancel key for instructing cancellation of indent control, the indent cancel control code is inserted into the text data in which the cursor is positioned and automatic line feed is performed. Since the cursor is positioned at the left margin position on the next line, the line feed operation after releasing the indentation is not required, and paragraphs can be edited easily using the indent function, and beautiful sentences can be created.
