Abstract

PURPOSE:To prevent a modifying character string from being divided at the time of shifting a line as the result of editing a document. CONSTITUTION:When a modifying character string (including a control code) exceeds the area of the number of characters in a line in a developing buffer 7 for storing a code string to be changed by document edition, the whole modifying character string is shifted to the next line in order to prevent the character string from being divided.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation device capable of adding various modifications to arbitrary characters in a document.

0002

2. Description of the Related Art Generally, a document creation device is provided with a function for adding various modifications to arbitrary characters in a created document. The contents of the modification include, for example, font (outlined, italic, rotated, mirror image, etc.), font size, shading, equal allocation, and the like. Setting of these character decorations is performed by specifying the starting point and ending range of the character string in the document. Strings with modifications (modified strings) are displayed with different attributes from other characters (for example, highlighted), or a symbol indicating the content of the modification is displayed on the guide line on the screen when the cursor is positioned. By doing so, it can be recognized on the display screen.

[Problem to be Solved by the Invention] When editing a document (inserting, deleting, copying, moving, etc.), the modified character string set by specifying a range is changed like other character strings according to the editing of the document. The display position etc. will be changed. For example, if you insert a character before a modified character string, the modified character string will be backed up in sequence just like other character strings. When the end of the line is reached, the line is sequentially moved back character by character to the next line. That is,
The qualified string specified in the range is split at the end of the line and the beginning of the next line.

[0004] However, a modified character string whose modification is set by specifying a range is originally meaningful when the string is continuous, so when it is divided at the end of a line and the beginning of a line, characters (spaces) are It was necessary to edit the modified strings by inserting them so that they were continuous.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a document creation device that does not divide modified character strings due to line crossing.

[0006]

[Means for Solving the Problems] The present invention provides a document creation device capable of displaying arbitrary characters in a document with various modifications. a determining means for determining whether or not the number of characters in one line is exceeded as a result of editing the document; The character string position changing means for moving the character string is also provided.

[0007]

[Operation] According to this configuration, as a result of document editing (character insertion, deletion, copying, etc.), the character string displayed in one line is changed, and consecutive characters with the same modification are added. If part of a column (modified character string) exceeds one line, the entire modified character string is moved to another line to maintain the original continuous character string state.

Next, the operation of this embodiment will be explained.

[0018] Here, an explanation will be given using enclosing rules (enclosing an arbitrary character string with predetermined ruled lines) as character decoration. first,
The procedure for setting enclosing borders will be explained.

First, when modifying a character, with the cursor moved to the beginning position of the character string to be modified, an instruction is given from the keyboard 16 to start setting the character modification (for example, "character modification"). (by pressing a key). As a result, a screen for specifying the range of character modification as shown in FIG. 2 is displayed on the display 18. On this screen, “
The character at the cursor position when the "Character Modification" key is pressed is displayed using other attributes (reverse, etc.), and the "Character Modification" key is pressed.
Where until? Display the "Specify the range and press the Select/Enter key" guide.

[0020] Here, when the cursor is moved to the last character position of the character string to be modified and the "Select/Execute" key is pressed, the modified character string is confirmed and a list of character modification items is displayed. is displayed as shown in FIG. Note that here, it is assumed that "good" is specified as the qualifying character string.

From the list of items, by moving the cursor to the character modification item to be selected and pressing the "Select/Execute" key, the contents of the modification can be arbitrarily specified. Here, when "0 enclosing rule" is selected, a list of enclosing rules for selecting the type of enclosing rule is displayed as shown in FIG. 4.

From the list of enclosing rules, an arbitrary enclosing rule can be specified by moving the cursor to the enclosing rule to be selected and pressing the "Select/Execute" key. Here, when one enclosing rule is selected, as shown in FIG. 5, the enclosing rule is added to the modified character string and displayed.

A ruled line surrounding a character string as shown in FIG. 5 can be created in the same shape on the display screen in ruled line creation mode or figure creation mode. However, in this case, editing of the document is not linked; for example, when a character is inserted, only the display position of the character string is changed, the position of the enclosing rule is not changed, and the character string is not modified. On the other hand, Figure 2~
In the case of character decoration (enclosing rule) set according to the procedure shown in FIG. 5, the display position of the enclosing rule is changed in conjunction with editing of the document, in accordance with the change in the position of the modified character string.

[0024] Next, the enclosing lines that are linked to the modified character strings when editing a document will be explained with reference to the flowchart shown in FIG. As shown in FIG. 5, when enclosing rules are set, the code is developed in the development buffer 7 as shown in FIG. That is, character codes are stored sequentially from the beginning of the line, and control codes indicating that the character string is to be modified are stored before and after the modified character string. Here, a control code indicating the start of the enclosing rule is stored before the character code for "good", and a control code indicating the end of the enclosing rule is stored after the character code for "i". When displaying a document, enclosing rules are also displayed based on the control code stored in the expansion buffer 7.

First, an instruction to edit a document is input (step S1). Here, by pressing a predetermined key on the keyboard 16, editing contents such as character deletion, insertion, and movement are instructed. Accordingly, the contents of the expansion buffer 7 are sequentially changed and the display screen is changed.

For example, as shown in FIG. 8, assume that a space is inserted with the cursor positioned before a modified character string. Every time an instruction to insert a space is given from the keyboard 16, a space code is stored in the expansion buffer 7 at a position corresponding to the cursor. Then, each time the contents of the expansion buffer 7 are changed, it is determined whether the enclosing rule end control code exists in the line area where the enclosing rule start control code is stored (does it not exceed the number of characters in one line)? (Step S2). In addition, when making this determination, RAM4
document format data (not shown) stored in a predetermined area of
Data indicating the number of digits in one line is referenced.

If the control codes for the start of the enclosing rule and the end of the enclosing rule exist in the area of the same line of the expansion buffer 7, the display is performed in accordance with the code stored in the expansion buffer 7 (step S4). ). Therefore, if the insertion of spaces is repeated in the state shown in FIG. 8, the display will be performed in the same way as when editing an unqualified character string until the state shown in FIG. 9 is reached.

Furthermore, if a space is inserted with a modified character string at the end of a line as shown in FIG. In step S2, it is determined that the enclosing rule end control code does not exist in the row area in which the enclosing rule start control code is stored.

In this case, the control code for starting the enclosing rule (including the character code) is moved to the next line area of the expansion buffer 7, and the prohibition code is stored instead (step S
3). As a result, as shown in FIG. 10, the entire modified character string (including the enclosing rule) is moved to the next line, and a screen is displayed in which a prohibition mark corresponding to the prohibition code is inserted at the end of the line.

[0030] In this way, if part of the modified character string crosses the end of a line due to document editing, the entire modified character string is moved to the next line, so the modified character string is not divided and is kept in the continuous state that it should be. can be kept.

[0031] In the above embodiment, the case of enclosing borders was explained as the character decoration, but other character decorations (
It can also be applied to uniform layout, font, font size, shading, etc.).

[0032]

As described above, according to the present invention, when a character string displayed in one line is changed as a result of document editing and a part of the modified character string exceeds one line, The entire modified string is moved to another line to avoid crossing over, so the original continuous string state is maintained.
