The data are developed to image data corresponding to pixels of the display 14 to be inputted to the memory 18.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a character display control device that allows a specified character string to be displayed within one line without spanning two lines.

2. Description of the Related Art Recently, devices called word processors have been commonly used to create documents.

When creating a document using this word processor, if the number of characters entered manually exceeds a set number of characters, the display is controlled so that the excess characters are automatically displayed on the display with a new line.

Problems to be Solved by the Invention However, when such control is performed, it can be said that it is significant in terms of improving input efficiency, but it is also important to display character strings with one meaning in an easy-to-read manner. There are still difficulties in this aspect.

In other words, a character string with a certain meaning, such as the name of something, may be displayed over two lines, so
There is a problem in that it is not easy to create documents that are easier to read.

The present invention has been made in view of such conventional problems, and aims to provide a character display control device in which a designated character string is displayed within one line.

Means for Solving the Problems To achieve the above objects, the present invention provides a setting means for setting arbitrary character strings manually entered into one group, and a storage means for storing the character strings set by the setting means. and,
When searching for a character string stored in the storage means from among human-generated character strings and displaying the character string, display control determines the end of a line so that the character string is displayed on the same line. It is characterized by having a means.

The character strings set into one group by the effect setting means are stored in the storage means. When displaying the character string stored in the storage means on a display medium such as a display or paper, the display control means determines the end of a line so that the character string is displayed on the same line. .

Therefore, since the set character string is always displayed within one line, it is possible to create a document that is easier to read.

Embodiments Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a schematic configuration diagram of a character display control device of the present invention. The CPU 10 is instructed to input arbitrary characters or to edit the input characters. Specifically, a keyboard 12 as shown in FIG. 2, an image buffer 16 for temporarily storing character data to be displayed on the display 14,
A display memory 18 that stores character data of an image buffer 16 to be displayed on a display 14 is connected. The image buffer 16 is a buffer having the same size as the display memory 18, and the arrangement of characters displayed on the display 14 is changed by changing the character data in the image buffer 16. The display memory 18 is a memory whose address corresponds to the address of the display 14, and the character data in the display memory 18 is displayed on the display 14 in the stored arrangement.

Characters entered manually from the keyboard 12 are displayed on the display 14 in the following manner. First, C
When character data is output from PU10 to the image buffer 16, the image buffer 16 stores this character data. When an editing command related to display is issued from the keyboard 12, this editing is performed in the image buffer 16.
This is done for character data within. This character data is developed into image data corresponding to each pixel of the display 14 and input to the display memory 18. The display 14 displays image data stored in the display memory 18.

The character display control device of the present invention operates as shown in the flowcharts shown in FIGS. 3 to 5, but before explaining the flowcharts, the general operation will be explained.

For example, the following characters are input, and in order to make the text easier to read, the character string "International Society" is specified not to be displayed across two lines (hereinafter referred to as word wrap).

) is displayed on the display 14 and printed as follows.

If the character string ``is input'' and the display shown above is displayed, the characters of the international community will be displayed over two lines, resulting in an ugly document. Here, if the characters ``International Society'' are specified and word wrap processing is performed, the display on the display 14 will be as shown below, and the characters ``International Society'' will be displayed on the same line.

- If there is a blank space below, first display the document on the display 14 and press the function key 12A (F) of the keyboard 12 shown in FIG.
4) When you press , a menu screen for word wrap processing is displayed on part of the document. This menu screen is as shown below (step 1).

word wrap processing This creates a very readable document.

The outline of the processing when word wrap is actually specified is as above, but next we will explain in more detail how the above processing is carried out based on the flowcharts from Figure 3 onwards. explain.

The flowchart in FIG. 3 is a process that is performed when the word wrap described above is specified.

Then, based on this menu screen, the user sets the search characters (in the above example, "international society" is entered manually), search direction, and search range (9 Japanese groups), and then presses the keyboard 12. Press the execution key 12B or the cancel key. At this point, the setting data for each item set on the menu screen is stored in the buffer (step 2). If the execution key is pressed in step 2, a search for the character string specified in the search character field will begin, but this search will not match the search target specified in the search direction and search range fields on the menu screen. The processing is performed on the character data stored in the image buffer 16 from the beginning of the document. Specifically, the processing is performed as follows.

The character data for one character stored in the image buffer 16 consists of one byte (8 bits) of an attribute that determines the attribute of the character, and one character that specifies the type of character.
It consists of a byte (8 bits) and 2 bytes (16 bits).

For example, for half-width alphanumeric characters, the attribute is xxox xxxx, and the character is xxxx xxxx.

The underlined half-width alphanumeric characters have attributes XXIX XX0O and characters xXXx xxxx.

The half-width kana characters are atorihutoka, xXIX xXOl, and character power, oxxx xxxx.

The full-width left character is Atrihyutoka, xXIX xxlX, and the character power is oxxx xxxx.

The full-width right-hand characters are Atrihyutoka, xxIX xXIX, and the characters are determined to be IXXX XXXXX. still,
The above bit O indicates OFF, 1 indicates ON, and X indicates either is acceptable.

Therefore, the search for the character string specified in the search character item is performed by comparing the character data that constitutes the character string against the input character data (step 3). When such a comparison is performed and the designated character string is retrieved (step 4), processing is performed to set this character string in the Japanese group. To put it simply, this Japanese group setting is done by setting the attributes of each character that makes up the character string to be unique to the Japanese group. Specifically, this is done as follows.

The JIS code for each country in the international community is 39.
71, but since this character is a double-width character, this J
The IS code is divided into two, 39 and 71. Since this JIS code is a character, the characters of this character are (OXOO39) and (OXOO71). When adding full-width left (OX2200) and full-width right (OX2280) as attributes to this, the character data of the national character becomes 0X22390X22F1. Similarly, the characters at the end are 0X223AOX22DD.

The character data of the company character is 0X223COX22D2.
The character data for the character of the society is 0X22320X22F1. When setting the item in step 2, if you set the character string "International Society" as a Japanese group, change the attributes representing each character from (OX2200) to (OX2300) if it is full-width left. For full-width right, from (OX2280) to (OX2380)
, respectively. Therefore, if the character string "International Society" is set to the Japanese group, the character data for the country character is 0X23390X23F1, the character data for the character is 0X233AOX23DD, and the character data for the company character is 0X23390X23F1. , 0x233COX23D2, and the character data of the characters of the society are changed to 0X23320X23F1, respectively. In this way, the international community character strings set are set as a Japanese group and can be distinguished from other character strings (step 5). Next, check the end of the line that contains the character string set as this Japanese group. Since the subroutine flowchart for checking the end of a line is shown in FIG. 4, the detailed process for checking the end of a line will be described later (step 6). As a result of this line end check, if it is determined that the line end should be changed (step 7), the line is re-separated (step 8), and the line end of the next line is checked (step 9). That is, from step 6 to step 9
In the processing, word wrap processing and prohibition processing will be performed. If it is determined in step 7 that there is no need to change the end of the line, the process returns to step 3 and the character string search process is restarted from the next character data. Further, in the judgment in step 4, if the search for all character data to be searched is completed, the character data in the image buffer 16 is sent to the display memory 18 and the screen is redisplayed (step 10).

The flowchart in FIG. 4 is a flowchart for checking the end of a line after word wrapping is performed as described above.

Before explaining the operation of this flowchart, an outline of the end-of-line check will be explained. First, the condition for the end of a line is a word break. This check starts with the last data in the row and proceeds toward the beginning of the row. This end-of-line check ends when a word break is found or when there is no break even after reaching the beginning of the line. This word break is basically a space, a tab, or a place where different types of characters are connected, such as between the ``u'' and ``工'' in ``Aiu Nio,'' for example, ``Processing''. There are three cases where full-width characters and full-width characters are connected, such as between ``dokoro'' and ``ri'' in ``.'' In other words, for half-width alphanumeric characters and half-width kana, consecutive character strings of the same type are 1
In double-width characters, one - character is one word.

In the word wrap process of the present invention, an exception is made to the definition of words using double-byte characters. The same can be said of the prohibition process. The prohibited characters in the prohibited process include characters prohibited at the beginning of a line and characters prohibited at the end of a line. Non-first-line characters are characters that cannot be placed at the beginning of a line, such as "," or "
. ” and “)”. In addition, end-of-line prohibited characters are characters that should not be placed at the end of a line, such as r cannot be used as a line separator.

Therefore, in the prohibition processing, a character prohibited at the beginning of a line is treated as one word, and a character prohibited at the end of a line is treated as one word, together with the word immediately following it.

In the word wrap process of the present invention, the double-byte characters of each character string set as a Japanese group are
As described above, since attributes different from those of other double-width characters are set, processing is performed so that the double-width character string set as the Japanese group is regarded as one word. Therefore, when word wrap processing is performed, a line break will not occur in the middle of the set character string.

First, the CPU 10 checks whether or not character data for which the end of the line has not been checked is stored in the image buffer 16 in the line searched in step 3 (step 20).
), if there is character data remaining that has not been checked at the end of the line, extract the character data. This character data is extracted in order from the end of the line to the beginning of the line (step 21). If the extracted character data is a break in an English word, this is the end of the line and the process returns to the main routine (step 22); if it is a full-width left, then the process returns to step 21 and the character data that is one character before the character data extracted in step 21 is returned to. Extract the data and perform the above processing. The reason for processing this way is that when the full-width left side reaches the end of the line, it separates from the full-width right side and no longer becomes a character (Step 2
3). Next, it is determined whether the following character is a prohibited character at the end of the line, but if the character data after the character data is a prohibited character at the end of the line, this cannot be made the end of the line, so the process returns to step 21 and is extracted again in step 21. Then, the character data immediately before the character data that has been retrieved is extracted (step 24). Furthermore, even if the retrieved character data is in the right half of the prohibited character at the end of the line, this cannot be made the end of the line, so return to step 21 and retrieve the character data immediately before the character data retrieved in step 21 again. (Step 25). If the retrieved character data is not the last character data set in the Japanese group, the previous character data is retrieved and the above processing is performed in the same manner as above.

This process is performed because the middle of the character string set in the Japanese group is not set as the end of the line (step 26). If the character data after the extracted character data is full-width left (step 27) or full-width right, this is the end of the line and the process returns to the main flowchart and ends (step 28). The characters that are processed up to step 27 are full-width right-hand or half-width characters that are not subjected to the prohibition process and are not in the Japanese group. In the case of full-width right, it applies to a combination of full-width characters and two full-width characters, and in the case of half-width, it applies to characters of different types connected. Processing up to step 28 is performed only in the case of full-width characters that are not subjected to Kinsoku processing and are not in the Japanese group, but since the character data at the end of this case is half-width characters, different types of characters are concatenated. It applies to what you have. If none of the conditions are met, the process returns to step 20, where it is checked whether unchecked character data remains in that line, and if so, one of the character data just checked in that line is checked. The previous character data is extracted and the end of line check process as described above is performed. If there are no lines remaining, the process returns to the main routine and ends the line end check process.

In a sentence like the one mentioned above, if you check the end of the line of the displayed character string after setting "International Society" to the Japanese group, the end of line check process will actually be performed as follows.

First, extract the character data of the right half of the character "Country",
A check is performed on this character data. In this case, the character ``Kuni'' is in the Japanese group, and the left half of the character ``Kai'' after it is also in the Japanese group, so it will not be at the end of the line. Then, a check is made on the left half character data of the character "country" which is the previous character data. This character data also does not end at the end of the line because of the full-width left-hand condition. Furthermore, the character data of the right half of the previous character data, "te", is extracted and a check is performed on this character data.

This meets the condition that the following character data is full-width left, so this is the end of the line. As a result of this check process at the end of the line, the line changes at ``te'' and the lines up to ``through the provision of reliable products and services'' are set to the -th line. Then, the second line is created by re-separating the character data after that. Then, a check process for the end of the second line is performed, but in this example, neither prohibition process nor word wrap occurs from the new second line onwards. After the above processing is performed, the following will be displayed on the display 14.

The character strings subjected to word wrap processing in this manner can be printed with their right ends aligned by performing uniform printing processing as shown in the flowchart of FIG.

The process of this flowchart is started by pressing the print key provided on the keyboard 12.

First, it is determined whether the first line contains a word-wrapped character string, and if the word-wrapped character string is not in that line, normal printing is performed (step 30). .31). On the other hand, if the word-wrapped character string is on that line, it is determined whether there is a newline code on that line (step 32).
. If there is a line feed code, send one line of character data to the printer as is; if there is no line feed code, calculate the distance of the blank space from the end of the line to the rightmost character.Step 33) The calculated distance is divided into minute spaces (step 34), and the divided spaces are distributed to character data corresponding to -digits, so that characters are printed at equal character intervals (step 35). Then, one line of character data that has been processed in this way is sent to the printer (
Step 36), proceed to the next line and repeat the processes from step 30 to step 38 until there are no unprinted lines, and when all lines have been printed, the process ends (steps 37 and 38).

When such uniform printing processing is performed, display 1
The character string displayed in 4 after Wardler-Tsubu processing is
When printing out, the following is displayed.Although this uniform printing process is automatically performed when word wrap processing is being performed, there is a case where the operator manually specifies the uniform printing. It may be.

In this way, by allowing any character string to be set in the Japanese group, the end of the line will be automatically determined and displayed on the display, and when printed, it will be printed evenly, making the document very easy to read. It can be easily created, and this function is particularly useful when the input document has been re-edited.

Note that this word wrap function may be used in combination with the replace and search functions. For example, if the replace and search functions can be used together, it will be possible to replace a specified string with another string and set it in the Japanese group at the same time, further improving usability. It turns out.

Effects of the Invention As is clear from the above explanation, according to the present invention, specified character strings can be displayed on the same line.
You can create very readable documents.
