Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device, and more particularly to a character processing device for creating a sentence using control codes such as indent, tab, and even allocation.

[0002]

2. Description of the Related Art In a conventional word processor, when control codes that determine the layout of a document such as indentation, tabs, and even allocation are set in the text, those control codes are normally represented by symbols at the beginning of the input character string. It is configured to be displayed.

[0003]

However, the control code in the conventional word processor is convenient for confirming the editing state of the input character string, but on the other hand, if a large number of control codes are set, the screen becomes complicated. become,
There was a problem that it was difficult to find the necessary information on the screen. In particular, when a ruled line is input, it is not easy to distinguish between the control code and the ruled line, which is an obstacle to the ruled line input operation.

The present invention has been made in consideration of the above circumstances, and a mode in which all control codes are collectively replaced by spaces for display and a control code arbitrarily selected by an operator is replaced by spaces for display. (EN) A character processing device capable of providing a screen display as needed by having both the modes.

FIG. 1 is a block diagram clearly showing the basic structure of the present invention. In the figure, the present invention comprises means 1 for inputting character information, means 2 for converting the character information into word information, means 3 for storing the converted word information, and means 4 for displaying the converted word information. In the character processing device, a designation unit 5 that designates a specific control code among control codes such as indents and tabs that determine the layout of text, and a control code storage unit 6 that stores the designated specific control code, Selection means 7 for selecting collective deletion or selective deletion for the control code being displayed
When the collective deletion is selected, the displayed control code is replaced with blank information, and when the selective deletion is selected, the displayed control code that matches the control code stored in the control code storage means 6 is displayed. It is a character processing device comprising a display switching means 8 for replacing only the blank information with blank information. The input means 1 in the present invention is preferably composed of a keyboard, and the designation means 5 and the selection means 7 can be assigned to the keys arranged on the keyboard.

[0006]

According to the present invention, when the batch erase is selected in the state where the text with the control code is displayed, all the control codes being displayed are replaced with blank information (space). Further, when the selective deletion is selected, the control code stored in advance in the control code storage means 6 by the operator is checked, and only the displayed control code corresponding to the control code is replaced with blank information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail based on the embodiments shown in the drawings. The present invention is not limited to this. FIG. 2 is a block diagram showing the configuration of a word processor which is an embodiment of the present invention. In the figure,
Reference numeral 10 denotes a main body of the apparatus, which mainly includes a CPU 11, a kana-kanji conversion processing unit 12, a display switching processing unit 13, a storage unit 14, and an output control unit 15, which are bus lines 16
Are interconnected by. Further, the CPU 11 is provided with a keyboard 17 externally and a CR via the output control unit 15.
T18 is connected to each. The kana-character string input from the keyboard 17 is encoded and given to the CPU 11, and the kana-kanji conversion processing unit 12 converts the kana-kanji mixed sentence into a kana-kanji mixed sentence.

The storage unit 14 is composed of a RAM and comprises a display mode buffer 140, a display code buffer 141, and a control code table 142. The display mode buffer 140 includes control codes (for example, indent, tab,
Information regarding display conditions of a code for deciding the layout of sentences such as even allocation, line breaks, page breaks, etc. is stored in a flag. The contents of identification by the display mode flag are display of control code, display of control code, and display of designated control code only. Display code buffer 14
Reference numeral 1 stores a display code created as a result of character input and editing performed by the CPU 11 and the kana-kanji conversion processing unit 12, and character codes and control codes are stored in a mixed manner. The control code table 142 is for storing a control code arbitrarily designated by the operator.

In such a structure, first, FIGS.
The control code designation will be described with reference to the screen display example of. When "control code display setting" is selected from the display items in the condition setting mode, the window W1 is displayed as shown in FIG. If the control code display "required" is selected, all the control codes are displayed. When the control code “No” is selected, all the control codes are not displayed. When the control code display "designation" is selected, only the control code designated by the operator is not displayed.

Further, when the "input required area display" is selected, a control code indicating a range that cannot be input (for example, a dot symbol string displayed after a line feed code)
Is displayed as usual, and the control code is not displayed when "No" is displayed for the non-input area display.

When "specify" is selected in the selection of the control code display, the window W2 shown in FIG. 4 is displayed next, and the control code which is not displayed can be selected by inputting the control code which is not displayed from the keyboard 17. Can be specified. If an indent, a line feed, and a page feed code are designated here, the designated control code is displayed in the window W2 as shown in FIG. 5, and when the execution key is pressed, those control codes are stored in the control code table 142. Ends the control code specification.

Next, the control code display process will be described with reference to the flowchart of FIG. When an instruction regarding the display of the control code is input from the keyboard 17, the following processing is performed for each character with respect to the code stored in the display code buffer 141. That is, the flag stored in the display mode buffer 140 is checked, and if it is arbitrarily designated (step 20), then it is checked whether the display code is a control code (step 21).
If the result of the check is that it is a control code, it is checked whether the same control code as that control code is stored in the control code table 142 (step 22).
When the same control code is stored in the control code table 142 (step 23), the control code is replaced with a space code (step 24).

In the case of NO in step 21 and in the case of NO in step 23, characters are generated from the display code through the VRAM (VideoRAM) and the character generator, and are displayed on the CRT 18 as in the conventional case. If NO in step 20, it is determined whether the display mode is batch designation (step 25), and Y
If it is ES, it is judged whether or not the display code is a control code (step 26), and if YES, all the control codes are replaced with space codes (step 24).
If NO in step 26, the control code is displayed on the CRT 18 as in the conventional case.

In this embodiment, the control code is collectively or selectively replaced with the space code, but the display code buffer 141 stores the display code before the replacement with the space code. Therefore, it goes without saying that the screen can be restored to the state before the space code replacement.

[0015]

According to the present invention, the control codes can be collectively replaced by spaces and displayed, and only the control codes arbitrarily designated by the operator can be replaced by spaces and displayed. Therefore,
The operator can select only the control code to be displayed, which enables efficient table creation, document creation and editing without being confused by complicated control codes.
