Controlled by the card interface 7 and the FD controller 9, data can be loaded and saved. The key interface 11 determines a key pressed on the keyboard 10 and converts the key into data corresponding to the key. The keyboard 10 is composed of various character keys and various function keys. In the present embodiment, in particular, in the present embodiment, a “start of line indent setting key”, a “end of line indent setting key”, an “indent release key”, a “column set key”, a “column set automatic”. It has a creation key, a column automatic release key, and the like. B is an address bus and a data bus.

In the following description, various display examples are shown. In these display examples, for example, as shown in FIG. 5, “A, B, C...
The mark referenced by 1 refers to the cursor, the mark referenced by M2 refers to a space (blank character), the mark referenced to M3 refers to an input prohibited area, the mark referenced to M4 refers to a line feed mark, and the mark referenced to M5. The mark referred to indicates a head-of-line indent mark, the mark referred to by M6 indicates a head-of-line indent mark, and the mark referred to by M7 indicates a de-indent mark.

Also, the broken lines as shown in FIG. 6 to indicate the boundaries of areas having different formats, and the mark referred to by M8 as shown in FIG. 9 represents a column mark. Further, as shown in FIG. 11, the area sandwiched between the two cursors represents the area designated as the area,
The dashed line as seen in FIG. 12 represents a page boundary.

FIGS. 5 and 6 show examples of display for realizing indentation at the beginning of a line and indentation at the end of a line according to the present embodiment (the number of characters per line is set to 10 characters). However, in the following description, the one-character erase key deletes one character at the position of the cursor and fills the subsequent sentences forward, and the backward key is one at the position of the cursor.
The next character is deleted by one character, and the following sentence is shifted forward.

The character input mode is an insert mode. When a key is input, a character or control mark corresponding to the key is displayed at the cursor position, and characters and control marks after that position are moved backward. Shall be.

FIG. 5 shows the original sentence. In this state,
When the cursor is moved to the first column of the third line and the space key is input once and the indent key of the line is input, the first line indent is set at the second column as shown in FIG. The second digit and the second digit are input-forbidden areas.

Here, for example, when the space key is input once at the first digit of the third line in the state of FIG. 5, one blank character is inserted, and the subsequent characters and the indent mark at the beginning of the line are set to 1
Move right by characters. Therefore, the position of the indent column at the beginning of the line is changed to the third digit.

Alternatively, in the state of FIG.
When the one-letter erase key is input once at the digit, the blank character at that position is deleted, and the subsequent characters and the indent mark at the beginning of the line move one character to the left. Therefore, the indent position at the beginning of the line is changed to the first digit. As described above, in this embodiment, the position of the indent column at the beginning of the line can be easily changed.

Next, in the state of FIG.
If you move to the column and enter the end-of-line indent key, the end-of-line indent is set to the ninth digit as shown in FIG. Become.

Next, when the cursor is moved to the ninth digit on the sixth line in the state shown in FIG. 5 and the indent release key is pressed, the state shown in FIG. 5 is obtained. Then, all the lines become an input-inputtable area (in the present embodiment, all the head indents and the head indents set before that position are released by the indent release key).

In the state shown in FIG. 5, the ninth digit after the third line is an input prohibited area. However, special characters and symbols such as punctuation marks, line feed marks, and indent release marks are input due to prohibition processing. Make it possible. FIG. 6 shows an example in which the sentence format (number of characters per line, character size, etc.) is changed on the fifth line.

In FIG. 6, when the cursor is moved to the third column and the first column, and the space key is input once and the indent key at the beginning of the line is input, the state shown in FIG. 6 is obtained. In the state of FIG. To enter the end-of-line indent key, the state shown in FIG. 6 is obtained. As described above, the line indent and the line indent become invalid after the line whose format is changed.

Further, in this embodiment, the indentation column position at the end of the line is not easily changed by editing work on the line where the indentation mark at the end of the line is inserted, and the indentation column position at the end of the line is easily changed when the operator thinks it is necessary. It shall operate as follows so that it can be changed.

In the state shown in FIG. 5, the cursor is moved to the 3rd line, 3rd column to 3rd line, 8th column, and a one-character delete key is input. When the back key is pressed, one character is deleted and the following text is moved forward, but the end-of-line indent mark does not move its position.

In the state of FIG. 5, when the cursor is moved to the third line and the ninth column (the position of the indent mark at the end of the line) and the backward key is pressed, the indent mark at the end of the line moves forward by one character and is there ( The third line, 8th column) character is the next line (4 lines 3
Digit), and from the fourth line onward, the 8th digit to the end of the line are input prohibited areas.

In the state shown in FIG. 5, when the cursor is moved to the third line and the ninth column (the position of the indent mark at the end of the line) and the one-character erase key is inputted, or the cursor is moved to the third line and the tenth column and the backward key is inputted. The end-of-line indent mark is erased, and the end-of-line input prohibition area for the third and subsequent lines disappears (return to the state of FIG. 5).

In the state of FIG. 5, when the cursor is moved to the third line and the third column to the third line and the eighth column and a character is input, the character is inserted at the cursor position, and the subsequent text is moved backward, but the end of the line is displayed. The indent mark does not move its position.

In the state of FIG. 5, when the cursor is moved to the third line and the ninth column (the position of the indent mark at the end of the line) and a character is input, the character is inserted at the cursor position, and the indent mark at the end of the line is moved backward. After the line, only the tenth line is a line end input prohibition area. FIG. 15 is a flowchart showing an operation when a one-character erase key is input to realize the above-described operation (in the case of a backward key input, the position to be erased is different by only one character. In the case of input, only the difference between deletion and insertion is omitted, so the flowchart is omitted).

First, when the one-character delete key is input, it is determined in step S1 whether or not there is an end-of-line indent code at the cursor position. If there is, the process proceeds to step S2, and if not, the process proceeds to step S4. In step S2, the line end indent code is deleted from the text data, and the setting of the line end indent is released. In step S3, since the end of line indent has been canceled, the display screen after the cursor position is rewritten by the conventional method, and the process of deleting one character ends. On the other hand, in step S4, the character or control mark at the cursor position is deleted from the text data.

In step S5, the cursor is moved to the next character. In step S6, it is determined whether or not there is an end-of-line indent code at the cursor position. If there is, the process proceeds to step S7; otherwise, the process proceeds to step S8.
In step S7, the end-of-line indent code in the sentence data is replaced with the next character of the code.
Proceed to 8.

In step S8, it is determined whether or not there is a line feed code at the cursor position. If there is a line feed code, the process proceeds to step S9; otherwise, the process returns to step S5. In step S9, the display on the display screen is rewritten according to the sentence data changed by the processing, and the processing of deleting one character is completed.
As described above, the indentation at the beginning of a line and the indentation at the end of a line can be easily realized.

Next, a method of creating a two-column sentence according to the present invention will be described. 7 to 9 show display examples of creating a two-column sentence (the number of characters per line is set to 10 characters). In this example, 2
Although a column system is used, a multi-stage system such as a three-stage system or a four-stage system can be realized by repeating the same procedure.

FIG. 7 shows the original sentence. In this state,
When the cursor is moved to the third line and the fifth column and the end-of-line indent key is input, the state shown in FIG. 7 is obtained, and from the third line onward, the region from the fifth column to the end of the line is a line end input prohibited area. Next, when the cursor is moved to the third line and the sixth column in the state of FIG. 7 and the indent key at the beginning of the line is input, the state of FIG. 7 is obtained, and the third and subsequent lines are in the fifth and sixth columns. It becomes an input prohibition area. In the state of FIG. 7, the third line and the sixth column are the input prohibition area, but the indent of the line can be input.

Next, in the state of FIG. 7, when any character or symbol is input in the input enabled area on the third row and the seventh digit,
The 10th line, 3rd column newline mark is changed to an indent release mark. Also, in the state of FIG.
After moving to the column and inputting the indent release key or the multi-column key, the text after the first digit on the sixth line in FIG.
After moving to the first digit, the state shown in FIG. 8 is obtained. From the sixth line onward, the area from the beginning of the line to the sixth digit is a line entry prohibited area.

FIG. 8 shows the case where the indent release key is input, but the subsequent operation is the same when the column key is input. When the cursor is moved to the fifth row and the fifth column in the state shown in FIG. 7 and the indent release key is input, the state shown in FIG. 7 is obtained.
When you enter the beginning of a line indent key to move to the line 6 digit,
As shown in FIG. 8, the text after the indentation mark is poured after the indentation mark at the beginning of the line.

Next, in the state of FIG. 8, when the cursor is moved to the fourth row and the eleventh column and the indent release key is input,
In the state shown in FIG. 9, the indentation at the beginning of the line is released from the sixth line onward, and all digits become an inputtable area (the indentation at the end of the line has already been released by the previous indentation release).
The same result can be obtained as shown in FIG. 9 by moving the cursor to the fifth row and the fifth column in the state of FIG. 7 and inputting a column key instead of inputting the indent release key.

The difference between the case where the indent release key is input and the case where the column key is input will be described below. In the case of the indent release key, a line feed function is included as in the conventional indentation of the line indent, but in the case of the column key, the line feed function is not included. Also, when editing such as insertion / deletion of a character at the front of the mark, the indent release mark moves forward and backward, but the column mark does not normally move. In the same way as in the case of the end-of-line indent mark, it moves to the left only when the backward key is pressed at the position of the mark, and moves to the right only when a character is input at the position of the mark.

FIG. 9 shows the operation in the case of the indent release mark. In the state shown in FIG.
When the character is moved to the digit and the one-character erase key is input, the character at the fourth digit in the fifth row is erased as shown in FIG. 9, and the indent release mark moves one character to the left. In addition, it does not affect the text after that (the third column and the seventh column and the sixth line and the first column and the subsequent columns).

FIG. 9 shows the operation in the case of a column mark. When the cursor is moved to the fifth row and the fourth column in the state of FIG. 9 and the one-character erase key is input, as shown in FIG. The character is erased to the fourth column and the fifth column, but the column mark does not move, and the character at the third column and the seventh column has moved to that position. To operate as described above, use the indent release key when changing columns at the end of one sentence, and use the column mark when changing columns in the middle of a sentence. good.

The above operation will be described with reference to the flowcharts of FIGS. FIG. 16 and FIG. 17 are flowcharts of the operation when the line indent key is input. When the indent key at the beginning of the line is input, it is first determined in step S1 whether or not the place where the key is input is within the input prohibition area. If it is not within the area, the process proceeds to step S2. If it is within the area, (step S15) Proceed to).

In step S2, a line head indent code is inserted into the text data stored in the RAM at the position indicated by the current cursor. The line head indent code is the same as the conventional line head indent, and is distinguished from the line head indent code for creating a multi-column sentence.

In step S3, an indent mark at the beginning of the line is displayed at the cursor position on the display screen (in the example of FIG. 5, the second digit of the third line). Note that the same mark as the head indent mark in the display examples of FIGS. 5 to 9 is used. In step S4, the set digit position of the line indent is stored in the RAM2. In step S5, the sentence data is displayed on the display screen from the column position of the line indent to the line end.

However, if an indent release code appears on the way or the sentence data ends, step S
6. The process proceeds to step S7 to perform processing. If an end-of-line indent code appears, display processing is performed according to the display flowcharts shown in FIGS.

In step S6, if an indent release code appears, the process proceeds to step S12. In step S7, it is determined whether or not the sentence data has been completed, and if so, the process of inputting the indent key at the beginning of the line ends. In step S8, it is determined whether or not the current display target line is the bottom line of the display screen, and if so, the process of inputting the indent key at the beginning of the line ends.

In step S9, the line to be displayed is moved to the next line. In step S10, it is determined whether or not the sentence format has been changed in the current display target line. If the sentence format has been changed, the process proceeds to step S13, and if not, the process proceeds to step S11.

In this embodiment, when the format is changed, it is assumed that format information is inserted at the beginning of the format change line in the text data. In step S11, a line head input prohibition mark is displayed from the line head to the line head indent setting digit, and the process returns to step S5.

On the other hand, if there is an indent release code in step S6, the process proceeds to step S12, but the process proceeds to step S12.
In step 12, an indent release mark is displayed on the display screen, and the process proceeds to step S13. In step S13, indent cancellation processing such as erasing the setting of the line indent digit position is performed.

In step S14, since the remaining text has been deindented, display processing is performed according to the conventional method, and the processing at the time of inputting the indent key at the beginning of the line ends. On the other hand, if it is determined in step S1 that the position is within the line end input prohibition region (such as the third row and sixth digit in FIG. 7), the process proceeds to step S15.

In step S15, it is determined whether there is an indent release code or a column code after the end-of-line indent code. If there is (in the case of FIG. 7), the process proceeds to step S17. If not, the process proceeds to step S17. In such a case, the process proceeds to step S16.

In step S16, the line indent code and the number of digits set at the beginning of the line are inserted at the end of the sentence data, and the flow advances to step S18 (the contents of the sentence data in FIG. 7 are as shown in FIG. 10). In step S17, a line head indent code and a line head indent set number of digits are inserted after the indent release code or the column code (the sentence data in FIG. 7 is input at the time when the line head indent key is input, as shown in FIG. 10). Become).

The line head indent code is a line head indent code for creating a multi-column text, and is distinguished from the line head indent code according to the conventional method. Also,
It is assumed that a number indicating the digit position at which the line indent is set is inserted at the same time as the position following the line indent code.

In step S18, the text after the end-of-line indent mark is displayed in accordance with the display flowcharts shown in FIGS. 19 to 22, and the process at the time of inputting the head-of-line indent key ends. FIG. 18 is a flowchart of the operation when the indent release key is input. When the indent release key is input, first, in step S1, RA
The indent release code is inserted at the position indicated by the cursor in the text data in M2. In step S2,
Displays an indentation mark at the cursor position on the display screen.

In step S3, it is determined whether or not the end of the sentence data is the line indent code (and the number of indent digits at the line beginning). If so, the process proceeds to step S4 (in the case of FIG. 7). If not, the process proceeds to step S5. In step S4, the line indent code and the line indent number at the end of the sentence data are moved to the position next to the indent release code (FIG. 7).
Therefore, when the indent release key is input at the fifth row and the fifth column, the sentence data is as shown in FIG. 10).

In step S5, display processing is performed after the end-of-line indent mark in accordance with the flowcharts shown in FIGS. 19 to 22 (FIG. 8). FIGS. 19 to 22 show flowcharts for displaying a sentence in which the line indent is set on the display screen.

Hereinafter, these flowcharts will be described with reference to the display example of FIG. In the following description, the first column of the two-column sentence (“U” on the third line in FIG. 9 to “F” on the fifth line) is the second column of the sentence (“G” on the third line in FIG. 9). "~
“N” in the fourth line) is called a sentence. Since the first and second lines in FIG. 9 are not columnar sentences, they are displayed by a conventional method.

Next, after displaying the first to fourth digits on the third line, there is a line end indent code, so a line end indent mark is displayed in step S1. In step S2,
The column position of the line end indent is stored in the RAM 2. In step S3, an indent release code or a column code is searched for the text data after the line end indent code.

In step S4, it is determined whether an indent release code or a column code is found, and if found, the process proceeds to step S5, and if not found, the process proceeds to step S9. In step S5, step S3
It is determined whether the data next to the indent release code or the column code found in the above is the line indent code, and if so, the process proceeds to step S6, and if not, the process proceeds to step S9. In this case, the display processing is performed when the line indent is set as shown in FIG. 7 but not in a two-column system as shown in FIG. 7).

In step S9, an input prohibition mark is displayed until the end of the line, and in step S10, the display target line is moved to the next line. In step S11, it is determined whether or not the sentence format has been changed. If so, the process proceeds to step S20, and if not, the process proceeds to step S12.

In step S12, it is determined whether or not the line indent is set. If it is set, in step S13, the input prohibition mark is displayed up to the set digit, and the process proceeds to step S14. Proceed to step S14. In step S14, the next sentence data is displayed up to the indent set digit at the end of the line. In step S15, it is determined whether or not the next sentence data is an indent release code.
Go to step S8, otherwise return to step S9.

If there is an indent release code in the process of displaying one sentence of a sentence in step S14, the process proceeds to steps S17 and S18 at that time to perform processing. In step S18, an indentation cancellation mark is displayed, in step S19, an input prohibition mark is displayed up to the end of the line, in step S20, indentation cancellation processing is performed, and in step S21, the remaining text is displayed by a conventional method, and the processing ends.

On the other hand, in step S6, the required number of input prohibition marks is displayed to the right of the end-of-line indent mark up to the line-indent mark display digit (in the case of FIG. 9, the line-end indent set digit is immediately adjacent to the line-end indent). , No entry prohibition mark). In step S7, an indent mark at the beginning of the line is displayed, and (step S2
Proceed to 2). The line to be displayed is the line at the end of line indent setting, and the display digit is the digit stored in the data following the line indent code.

In step S22, it is determined whether there is a sentence that has not been displayed. If so, the flow advances to step S23 to display sentence 2 until the end of the line. If not, the flow advances to step S24. In step S24, it is determined whether or not the indentation at the beginning of the line has been canceled. If the indent has not been canceled, the process proceeds to step S25, and if it has been canceled, the process proceeds to step S26.

In step S25, a blank character (or some control mark) is displayed until the end of the line.
The process proceeds to step 29 (this is for the case where the indentation at the beginning of the line has not been canceled as shown in FIG. 7 but no character has been input to the text). In step S26, the input prohibition mark is displayed until the end of the line, and the process proceeds to step S30. (This is a case where there is no sentence because the indentation at the beginning of the line has been canceled as in the fifth line in FIG. 9, but there is a sentence. Because of that).

In step S30, it is determined whether or not the end of line indent has been released. If it has not been released, the process proceeds to step S30. If it has been released, the process ends.

On the other hand, from step S22 to step S23
If the process proceeds to step S27 to display the sentence 2, the process proceeds to step S27 to determine whether the next data is an indent release code. If it is determined in step S27 that the code is an indent release code, the flow advances to step S28 to perform processing for releasing the indentation at the beginning of the line and display an indent release mark, and then the flow advances to step S29.

If an indent release code appears during the display up to the end of the line in step S23, the process proceeds to steps S27 and S28 at that point to perform a line indent release process. In step S29, it is determined whether or not the next data is an end-of-line indent code. If the next data is different (step S31), the process proceeds to the next line, and if so, the process is performed (step S1).
(If there is an end-of-line indent code, there is a possibility that the sentence is a three-column sentence, so the process returns to step S1 and repeats the process recursively.)

In step S31, it is determined whether or not the current line to be displayed is the bottom line of the display screen. If so, the display process is terminated.
Proceed to 2 to move the display target line to the next line. In step S33, it is determined whether there is text data,
If there is, go to step S34; otherwise, go to step S37. In step S37, it is determined whether or not there is text data. If there is, the process proceeds to step S38, and if not, the display process ends.

In step S38, the input prohibition mark is displayed from the beginning of the line to the indent setting digit at the beginning of the line (from the first digit to the sixth digit in the sixth line in FIG. 8), and the process returns to (step S22). On the other hand, in step S34, the sentence is displayed up to the indent set digit at the end of the line. In step S35, it is determined whether or not the next data is an indent release code. If so, the process proceeds to step S23; otherwise, the process proceeds to step S39.

In step S36, a line end indent release processing is performed, and the flow advances to step S39 (hereinafter, it is assumed that there is no sentence). If an indent release code appears during the display in step S34, the process proceeds to step S35 / step S36 at that point to perform line end indent release processing.

In step S39, an input prohibition mark is displayed up to the indent setting digit at the beginning of the line (step S22).
Return to By performing the processing according to the above-described flow, a sentence in which both the indent at the end of the line and the indent at the beginning of the line are mixed can be displayed on the display screen. In other words, it is possible to easily create a multi-column sentence.

Next, automatic column creation according to the present invention will be described. In the following description, the area designation means to designate a certain range in a sentence. However, since this is a known technique, a detailed description is omitted. FIG. 11 and FIG. 12 are display examples for explaining this function. FIG.
When the area is specified from the 3rd line, 1st digit to the 5th line, 11th column and the column setting automatic creation function key is entered, the number of columns and the number of characters in the inline input prohibited area are called. By answering, the result as shown in FIG. 11 is automatically obtained. In this display example, the number of columns is 2, and the number of characters (column spacing) in the in-line input prohibition area is 2.

If the page changes halfway, for example, if the page changes between the fourth and fifth lines in FIG. 11, a different result as shown in FIG. 12 is obtained. FIG.
3 is a flowchart for automatically creating a column. Step S
In step 1, it is determined whether or not an area has been designated. If so, the procedure proceeds to step S3. If not, the procedure proceeds to step S2, where the area is designated, and then the procedure proceeds to step S3.

In step S3, it is determined whether or not the format has been changed in the designated area. If so, the flow proceeds to error processing in step S4, and if not, the flow proceeds to step S5. In step S4, error processing such as displaying an error message is performed, and the process ends. If the format is changed in the middle, a correct result cannot be obtained unless special processing is performed.

In step S 5, the operator inputs the number of columns from the keyboard 10. In step S6, the number of characters in the in-line input prohibited area is input from the keyboard 10. However, since at least two indentation marks must be displayed, at least one full-width character is used (when the indentation mark is half-width). Step S
In step 7, the number of digits in one column is calculated by the following formula (if not divisible, the remainder is stored in the RAM 2 and the decimal part is rounded down). (Number of characters in one line-Number of characters in input prohibited area in line x (Number of columns)-1)
{Number of Column Sets} In the example of FIG. 5, four digits are obtained from (10-2 (2-1)) ÷ 2.

In step S8, a line end indent is inserted into a place where the number of digits calculated in step S7 is obtained (in the example of FIG. 11, the third row and the fifth digit) (FIG. 11).
State). In step S9, the process of inserting a line head indent is performed as shown in the flowcharts of FIGS. 16 and 17 in a place where the number of characters in the in-line input prohibition area is satisfied (in the example of FIG. 11, the third column, the sixth digit). .

In step S10, the number of the line where the indent release code is to be inserted is calculated by the following formula (if it cannot be divided, the decimal part is rounded up). In the example of FIG. 11, the total number of rows in the area is from the third row to the tenth row, as shown in FIG.
$ 2 results in four rows.

In step S11, in the case of the number of lines obtained in step S10, it is determined whether or not a page does not protrude in the middle, and if not, the process proceeds to step S13.
If it does, the process proceeds to step S12 (in FIG. 11,
If the page changes between the fourth and fifth lines, the result of FIG. 12 is obtained instead of FIG. 11).

In step S12, the number of lines is reduced so as not to protrude from the page.
2 and the process proceeds to step S13 (in FIG. 11, when the page changes between the fourth and fifth rows, the number of rows is two). In step S13, the location of FIG.
As shown in the flow chart of FIG.

In step S14, it is determined whether or not the processing for the number of columns has been completed.
The process proceeds to step S5, and if not, returns to step S8. In step S15, if there is a remainder in step S7, a line end indent is inserted so that an input prohibition region is formed at the end of the line by the number of remaining characters. In step S16, an indent release code is inserted at the end of the area. Step S17
Then, if it is determined in step S11 that the page runs off, the process proceeds to step S18, and if not, the process ends.

In step S18, the number of lines that have been reduced in order to protrude the page in step S12 is newly set,
It returns to step S7. As described above, a sentence as shown in FIG. 11 or FIG. 12 can be automatically created simply by designating the area and inputting the number of columns and the number of characters in the in-line prohibited area.

Next, automatic column release will be described. Automatic column clearing means that if there is a columnar text as shown in FIG. 13, if a range is specified and executed, the columns within the range are released and the results shown in FIGS. What you can get. FIG. 13 shows the result when the entire range from the first line to the tenth line in FIG. 13 is designated. Similarly, FIG. 13 shows the first to fifth lines in FIG.
3 shows the result when the sixth to tenth lines are designated, and FIG. 14 shows the result when the fourth to seventh lines are designated.

The reason why the line feed mark is attached to the end of the fourth line in FIG. 13 and FIG. 13 is that the indent release mark on the tenth line and the fifth column in FIG. 13 has been changed to a line feed mark. If a column mark is used instead of the indentation mark, a line feed mark is not added. FIG. 24 and FIG. 25 are flowcharts for realizing automatic column release. In this embodiment, the keyboard 1
It is assumed that when a column automatic release function key set on the input unit 0 is input, the automatic column release processing is started.

In step S1, it is determined whether or not an area has been designated.
If yes, go to step S3. In step S2, the area specification is the entire range of the columnar text (in the example of FIG. 13,
The first line to the tenth line) are set to be designated as an area, and the process proceeds to step S4. In step S3, it is determined whether or not the area is specified in the entire range of the columnar text. If so, the process proceeds to step S4, and if not, the process proceeds to step S4.

The flow from step S4 is a flow for automatically canceling the entire range of columns. In step S4, the end-of-line indent code (the fifth digit in the first line in the example of FIG. 13) is deleted from the text data in the area. In step S5, the indent code at the beginning of the line (the sixth digit in the first line in FIG. 13) is deleted from the text data in the area.

In step S6, it is determined whether the last (first row, fifth column in FIG. 13) of the first column in the area is a column code or an indent release code. If it is an indent release code, the process proceeds to step S7. In step S7, the indent release code is changed to a line feed code, and the process proceeds to step S9.

In step S8, the column code is deleted, and the flow advances to step S9. In step S9, the indent release code (10th line, 9th digit in FIG. 13) at the end of the second sentence in the area is changed to a line feed code. In step S10, the display screen is rewritten to the screen of the final result, and the process ends.

As described above, steps S4 to S1
By the processing of 0, for example, from the first row in FIG.
When the area is specified up to the line and the column automatic release is executed, a result as shown in FIG. 13 can be obtained. On the other hand, after proceeding to step S3, in step S11, is an area specified in the upper part of the column text (including the indent mark at the end of the line and the indent mark at the beginning of the line, but not including the column mark and the indent release mark)? , Whether the area was specified at the bottom (including the column mark / indent mark, but not the end-of-line indent mark / head-of-line indent mark) or in the middle (line-end indent mark /
It is determined whether an area has been designated at the line indent mark (between the column indent mark and the column mark / indent release mark), and step S12, step S16, and step S2 are performed, respectively.
Proceed to 2.

In step S12, the digit position of the line end indent and the digit position of the line indent are stored in the RAM 2. In step S13, the same processing as in steps S4 to S8 is performed, and the entire column text is released. In step S14, using the column positions of the line end indent and the line indent stored in step S12,
The column automatic creation process similar to the flowchart shown in FIG. 11 is performed on the line following the designated area (the sixth line in FIG. 13) and thereafter. In step S15, the display screen is rewritten to the screen of the final result, and the process ends. As described above, by the processing of steps S12 to S15, for example, FIG.
Therefore, when the area is specified from the first line to the fifth line and the column automatic release is executed, the result as shown in FIG. 13 can be obtained.

On the other hand, if it is determined in step S11 that an area has been designated at the bottom of the columnar text, the process proceeds to step S11.
In step 16, a column code is inserted at the end of the first sentence on the first line of the designated area in the sentence data (fifth row, fifth column in FIG. 13) (provided that the last data is a line feed code). In this case, the line feed code is changed to the indent release code without inserting the column code.)

In step S17, the indent code at the beginning of the line (the sixth digit in the first line in FIG. 13) in the text data is moved to the position next to the column code. In step S18, the column code (10th line, 5th column in FIG. 13) is deleted (however, if not the column code but the indent release code is used, the indent release code is changed to a line feed code). .

In the step S19, the end of the second row of the text on the specified line in the text data (5 in FIG. 13).
Insert the indent release code at line 11 (column 11). In step S20, the last indentation code of the text data (9th line, 9th digit in FIG. 13) is changed to a line feed code. In step S21, the display screen is rewritten to the screen of the final result, and the process ends. As described above, by the processing of steps S16 to S21, for example, FIG.
Therefore, if the area is specified from the sixth line to the tenth line and the column automatic release is executed, a result as shown in FIG. 13 can be obtained.

On the other hand, if it is determined in step S11 that an area has been designated in the middle of a multi-column sentence, the column position of the line indent and the column position of the line indent are stored in the RAM 2 in step S22. Step S2
In step 3, a column code is inserted at the end of the first sentence on line 1 of the designated area in the sentence data (3rd line, 5th digit in FIG. 14) (however, if the last data is a line feed code). In this case, the line feed code is changed to the indent release code without inserting the column code.)

In step S24, the indent code at the beginning of the line (the sixth digit in the first line in FIG. 14) in the text data is moved to the position next to the column code. In step S25, an indent release code is inserted at the end of the second row of text on the specified line in the text data (3rd line, 11th column in FIG. 14). In step S26, the column code (10th row, 5th column in FIG. 13) is deleted (however, if the indent release code is used instead of the column code,
Change the indentation code to a line feed code).

In step S27, using the column positions of the line end indent and the line indent stored in step S22, a column automatic creation process similar to that shown in the flowchart of FIG. 11 is performed. (8th line)
It will be done later. In step S28, the display screen is rewritten to the screen of the final result, and the process ends.

As described above, by performing the processing in steps S22 to S28, for example, when the area is specified from the fourth line to the seventh line in FIG.
The result as shown in FIG. 14 can be obtained. As described above, a multi-column text (mixing with no column and the number of digits can be freely set) can be automatically created and released.
