[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information processing apparatus for editing a document, and more particularly to an information processing apparatus that performs batch erasure to the beginning or end of a line.
[0002]
[Prior art]
In recent years, the processing capability of a CPU (Central Processing Unit) has been improved, and the processing speed of information processing apparatuses has been steadily improving. Along with this, there is a growing demand for improved operability of software such as editing processing.
[0003]
FIG. 32 is a diagram illustrating an example of an editing screen in a conventional information processing apparatus.
When the display length of one line exceeds the displayable range of the editing screen, the part exceeding the displayable range is not displayed (see FIGS. 33A and 33B), or is displayed folded on the next line. (See FIG. 33 (c)). In FIG. 33C, “/” at the end of the line indicates that the display is folded. When the display length of one line is specified (when the display length of one line is smaller than the displayable range of the edit screen), the portion exceeding the display length of one line is regarded as the character data of the next line. It was considered and displayed (refer FIG.33 (d)).
[0004]
FIG. 33 is a diagram showing batch erasure processing in the line end direction in the editing processing system using the editing screen described above. FIGS. 33A to 33C show batch erasure in the direction of the end of the line when a portion exceeding the displayable range is not displayed when the length of one line exceeds the displayable range of the edit screen. . When the cursor is at the position “a” (FIG. 33 (a)), if batch erasing is performed in the direction of the end of the line, other character strings are deleted leaving the last line feed mark on the line (FIG. 33 (b)). )). Further, when the cursor is at the position of the line feed mark (FIG. 33 (b)), if erasing is performed in the direction of the end of the line, the following lines are moved up by one line (FIG. 33 (c)).
[0005]
FIGS. 33 (d) and 33 (e) show the direction of the end of the line when the display length of one line exceeds the displayable range of the edit screen and the portion exceeding the displayable range is folded and displayed on the next line. Batch erase is shown. When the cursor is at the position “a” (FIG. 33 (d)), if a batch erase is performed in the direction of the end of the line, only the line feed mark on the next line is left and the character string displayed by wrapping is deleted. (FIG. 33 (e)).
[0006]
FIGS. 33 (f) and 33 (g) show collective erasure in the end-of-line direction when the display length of one line is defined. When the cursor is at the position of “A” (FIG. 33 (f)), if batch erasing is performed in the direction of the end of the line, only one line is erased and the following lines are moved up one line at a time (FIG. 33 ( g)).
[0007]
FIG. 34 is a diagram showing batch erasure processing in the line head direction in the editing processing system using the editing screen described above.
[0008]
FIGS. 34 (a) and (b) show collective erasure in the direction of the line head when the portion exceeding the displayable range is not displayed when the length of one line exceeds the displayable range of the edit screen. . When the cursor is at the position of “ka” (FIG. 34 (a)), if a batch erasing is performed in the direction of the beginning of the line, all character strings before “ka” are erased (FIG. 34 (b)).
[0009]
34 (c) and 34 (d) show the direction of the head of the line when the display length of one line exceeds the displayable range of the editing screen and the portion exceeding the displayable range is folded and displayed on the next line. Batch erase is shown. When the cursor is at the position of “ka” (FIG. 34 (c)), if the entire line is erased in the direction of the beginning of the line, all the character strings before “ka” are erased, and the next line is moved up one line. It is displayed after “ka” (FIG. 34D).
[0010]
FIGS. 34 (e) and 34 (f) show collective erasure in the direction of the line head when the length of one line is defined. When the cursor is at the position of “ku” (FIG. 34 (e)), if batch erasing is performed in the head of the line, all character strings before “ku” are erased, and the character string after “ku” is 1 It is displayed on the line (FIG. 34 (f)).
[0011]
The following inventions are disclosed as related technologies of this type.
In the invention disclosed in Japanese Patent Laid-Open No. 60-102688, the document area of the display screen is divided into a control code dedicated area and a character area to perform editing processing.
[0012]
In the invention disclosed in Japanese Patent Application Laid-Open No. 60-103387, a line feed mark or a page break mark is handled in the same manner as other characters, thereby inserting a line feed mark or a page break mark at an arbitrary position on the display screen. , And can be deleted.
[0013]
In the invention disclosed in Japanese Patent Laid-Open No. 1-234968, when a character string such as a word or the like is connected by a hyphen over two lines, the word or the like is erased collectively by a one-key operation.
[0014]
In the invention disclosed in Japanese Patent Laid-Open No. 4-47448, when new data by column editing exceeds the set format area, the data is stored and an identification mark is displayed at the right end position of the screen.
[0015]
[Problems to be solved by the invention]
As described above, when the display length of one line exceeds the displayable range of the editing screen, the batch erasure in the line end direction or the line head direction when the portion exceeding the displayable range is not displayed is shown in FIG. ) To (c) or as shown in FIGS. 34 (a) and 34 (b), character strings that are not displayed on the display screen are also erased together. Accordingly, even character strings that are not intended by the operator may be deleted.
[0016]
When the display length of one line exceeds the displayable range of the edit screen, batch erasure in the line end direction or the line head direction when the portion exceeding the displayable range is folded back to the next line and displayed is shown in FIG. As shown in (d) and (e) or FIGS. 34 (c) and (d), the number of characters from the position of the cursor to the actual end of line or the actual beginning of the line is the apparent end of line or the beginning of the line on the screen. Therefore, even a character string that is not intended by the operator may be deleted.
[0017]
Further, when the display length of one line is specified, batch erasing in the end direction of the line is performed once when one line in the document extends over two lines on the display screen as shown in FIG. Subsequent lines are moved up one line at a time by batch erasure (see FIG. 33G). However, when one line in the document is one line on the display screen, only the line feed code at the end of the line remains after one batch erasure, and the subsequent lines are not carried forward. Therefore, the operation could not be unified.
[0018]
The inventions disclosed in the above Japanese Patent Laid-Open Nos. 60-102688 and 60-103387 do not describe batch erasing in the end-of-line direction or in the start-of-line direction. I can't.
[0019]
In addition, the invention disclosed in Japanese Patent Laid-Open No. 1-234968 includes a description about collective erasure. However, the target of batch erasure is a word or the like connected with a hyphen, and there is no description about erasing a line. Also, there is no mention of the relevance to the display screen by batch erasure.
[0020]
Furthermore, the invention disclosed in Japanese Patent Laid-Open No. 4-47448 describes a case where new data by column editing exceeds the set format area. However, it does not describe how the processing is performed when batch erasing in the line end direction or line head direction is performed.
[0021]

Position specifying means for designating, when the display length of one line of document data exceeds the displayable range of the display means, folding means for causing the display means to wrap and display the next line, and position specifying means When there is an instruction to erase from the specified position to the end of the line, the character string from the specified position to the end of the line is erased except for the character string returned to the next line by the return means. IncludingThe processing means deletes the character string other than the character string returned to the next line by the return means in the character string from the designated position to the end of the line when the delete instruction is given. Inserts a line feed code just before the character string wrapped to the next line
[0038]
The character string up to the cursor before erasure and the character string returned to the next line by the wrapping means are divided by the line feed code, so the part before and after the erased character string becomes clear, and the operability of the subsequent editing work improves.
[0043]
Claim7The information processing apparatus described in the above item specifies a storage means for storing document data, a display means for displaying the document data stored in the storage means, and a position in the document data displayed on the display means Specified by the position specifying means, and when the display length of one line of the document data exceeds the displayable range of the display means, the return means for returning the display line to the next line and displaying it by the position specifying means If there is an instruction to delete from the specified position to the beginning of the line, if the position specified by the position specifying means is on the next line that has been folded, the line from the specified position to the beginning of the next line is deleted. Including processing means forHowever, if there is an erasure instruction, the processing means erases the specified line from the specified position to the beginning of the next line if the position specified by the position specifying means is on the next line. A line feed code is inserted immediately after the character string that is not returned by the return means.
[0046]
Since the character string after the cursor before erasure and the character string that is not folded by the folding means are divided by the line feed code, the erasure of the erased character string becomes clear and the operability of the subsequent editing work is improved.

DETAILED DESCRIPTION OF THE INVENTION
[Embodiment 1]
FIG. 1 is a block diagram showing the configuration of the information processing apparatus according to Embodiment 1 of the present invention.
[0053]
The information processing apparatus includes a CPU 1 for executing programs, a RAM (Random Access Memory) 2 for storing various data, a ROM (Read Only Memory) 3 for storing control programs and fixed data, and a printer controller 4. , Printer 5, HD (Hard Disk) controller 6, HD 7, mouse interface 8, mouse 9, display device 10, display controller 11, pen 12, pen interface 13, keyboard 14, key interface 15, FD (Floppy Disk) 16, FD controller 17, IC card 18, IC card interface 19, pen tablet 20, pen tablet interface 21, OCR (Optical Character Read) r) interface 22, and a OCR23.
[0054]
The HD 7, FD 16 and IC card 18 are controlled by the HD controller 6, FD controller 17 and IC card interface 19, respectively, and data can be loaded / saved. The key interface 15 discriminates the key pressed on the keyboard 14, converts it into key data corresponding to it, and outputs it. Further, the mouse interface 8 and the pen interface 13 determine the coordinates on the screen of the display device 10 designated by the mouse 9 and the pen 12, respectively, convert the coordinates into XY coordinates, and output them. In addition, the pen tablet interface 21 determines the coordinates input to the pen tablet 20, converts them to XY coordinates, and outputs them. Further, the OCR interface 22 converts the image data read by the OCR 23 into bitmap data and outputs it.
[0055]
FIG. 2A shows a displayable range in the first embodiment. An inner rectangular area indicates a displayable range in the display device 10. The width of the outer rectangular area indicates the display length of one line. The amount of scrolling between the characters at the left end of the document line and the characters actually displayed at the left end of the screen is the line head scroll amount.
[0056]
FIG. 2B shows the relationship between the document buffer, various pointers, and flags. The document buffer is a storage area that is set in the RAM 2 and stores character data in the document. The cursor pointer is a storage area for storing a pointer that is set in the RAM 2 and indicates which character on the screen the cursor is on. The erasure start pointer is set in the RAM 2 and is a storage area for storing a start pointer for erasing character data from the document buffer. The erasure end pointer is set in the RAM 2 and is a storage area for storing an end pointer when erasing character data from the document buffer.
[0057]
An erase start pointer SAVE is a storage area that is set in the RAM 2 and temporarily stores the erase start pointer. The flag that is not deleted outside the display range is a storage area that is set in the RAM 2 and stores a flag for controlling whether or not to erase a character string that is not displayed on the display device 10 beyond the displayable range. is there. The flag that is not deleted outside the display range is set in advance. When 00H is stored, the character string that exceeds the displayable range is deleted, and when FFH is stored, the portion that exceeds the displayable range. Indicates that will not be deleted.
[0058]
The flag 2 not to be erased outside the display range is set in the RAM 2 and displays a message on the display device 10 as to whether or not to erase the character string that is beyond the displayable range and is not displayed on the display device 10. This is a storage area for storing information on whether or not to instruct deletion. When 00H is stored, the character string is erased. When FFH is stored, it indicates that the character string is not erased.
[0059]
The flag that does not erase the return line is set in the RAM 2. When the display length of one line exceeds the displayable range, the character string that exceeds the displayable range is displayed on the next line, and the line from the cursor to the end of the line is deleted. This is a storage area for storing information as to whether or not to erase the character string displayed on the next line when an instruction to do so is issued. When 00H is stored, the character string is erased. When FFH is stored, it indicates that the character string is not erased. The flag that does not erase the folded line is not used in the first embodiment, but is used in the second embodiment to be described later.
[0060]
FIG. 3 is a flowchart showing a processing procedure when erasing in the line end direction or line head direction in the first embodiment.
[0061]
First, an instruction from the operator is waited (S100). An instruction from the operator is given by the mouse 9, the pen 12, the keyboard 14, or the pen tablet 20. If there is a line end direction erasure instruction (S101, Yes), the process proceeds to S104, and the line end direction erasure process is performed. When there is no line end direction deletion instruction (S101, No), the process proceeds to S102 to determine whether or not there is a line end direction deletion instruction. When there is an instruction to delete the head of a line (S102, Yes), the process proceeds to S105, and a process of deleting the head of the head is performed (S105). On the other hand, if there is no instruction for deleting the head direction (No in S102), the process proceeds to S103, and after returning to other processes, returns to S100 to wait for an instruction.
[0062]
4 and 5 are flowcharts showing the processing procedure of S104 in FIG. First, the cursor pointer is set to the erase start pointer (S201). If the cursor pointer is on the line feed code (S202, Yes), the next position of the line feed code is set in the erasure end pointer (S204), and the character data from the erasure start pointer to the erasure end pointer is deleted. (S219) The screen after erasure is displayed (S220). That is, only the line feed code is deleted, and subsequent lines are moved up one line at a time.
[0063]
If the cursor pointer is not on the line feed code (S202, No), it is checked whether or not the flag not to be erased outside the display range is FFH (S203). If the flag not to be erased outside the display range is not FFH (No in S203), the line feed code position appearing after the cursor pointer is set in the erase end pointer (S219), and the character data from the erase start pointer to the erase end pointer is deleted. Then, the interval is filled (S220), and the screen after erasure is displayed (S220). That is, the part from the cursor position to before the line feed code is deleted.
[0064]
If the flag not to be erased outside the display range is FFH (S203, Yes), the cursor pointer is set to the erase end pointer (S205). If the size obtained by subtracting the head scroll amount from the display length from the beginning of the line to the erase end pointer is smaller than the screen size in the digit direction (S206, No), the erase end pointer is shifted by one character toward the end of the line (S208), and again from the beginning of the line. The size obtained by subtracting the head scroll amount from the display length up to the erase end pointer is compared with the digit-direction screen size (S206). This process is repeated, but if a line feed code appears in the middle, the process proceeds to S220. When the size obtained by subtracting the line head scroll amount from the display length from the beginning of the line to the erasure end pointer is larger than the screen size in the digit direction (S206, Yes), the operator is asked whether or not to erase the character string that exceeds the displayable range. A message is displayed (S207), and an instruction from the operator is awaited (S209). FIG. 9 shows an example of this message. When the outside of the display range is erased by an instruction from the operator (S210, Yes), the process proceeds to step S212.
[0065]
If the instruction from the operator does not erase outside the display range (S210, No), FFH is set in the flag 2 not erased outside the range (S211), and the character data from the erase start pointer to the erase end pointer is deleted. (S212). Changes in display on the screen at this time are shown in FIG. 6 or FIGS. 10 (a), 10 (b) and 10 (d). When the insertion of line feed is set (S213, Yes), a line feed code is inserted at the position where the cursor pointer is (S214). The change in display on the screen at this time is shown in FIG. When it is not set to insert line feed (S213, No), screen display is performed without inserting a line feed code (S215). When FFH is set in the flag 2 that is not erased outside the display range (S216, Yes), the erasing in the line end direction is terminated.
[0066]
When the flag 2 not to be erased outside the display range is not FFH (No in S216), it is determined whether or not the character string to be erased is temporarily displayed (S217). When the character string to be erased is temporarily displayed (S217, Yes), the screen is displayed for a predetermined time (S218). Then, the line feed code position is set in the erasure end pointer (S219), the character data from the erasure start pointer to the erasure end pointer is deleted, the gap is cleared (S220), and the screen after erasing the character string is displayed (S221). . That is, the process from the cursor position to the line feed code is deleted and the process is terminated. The change in display on the screen at this time is shown in FIG.
[0067]
If the character string to be erased is not temporarily displayed (S217, No), the line feed code position is set in the erase end pointer (S219), and the character data from the erase start pointer to the erase end pointer is deleted. The screen after erasing the character string (S220) is displayed (S221). Changes in the display on the screen at this time are shown in FIGS.
[0068]
11 and 12 are flowcharts showing the processing procedure of S105 in FIG.
[0069]
First, the cursor pointer is set as the erase end pointer (S301). If the cursor pointer is at the beginning of the line (S302, Yes), the process is terminated as it is. If the cursor pointer is not at the beginning of the line (S302, No), it is determined whether or not the flag that does not erase outside the display range is FFH. If the flag not to be erased outside the display range is not FFH (S303, No), the line head position is set to the erase start pointer, and the cursor pointer position is set to the erase end pointer (S322). The character data from the erase start pointer to the erase end pointer is deleted and paused (S323), and the erased character string is displayed on the screen (S324).
[0070]
If the flag not to be erased outside the display range is FFH (S303, Yes), the cursor pointer is set to the erase start pointer (S304). If the line head scroll amount is 0 (S305, No), the line head position is set to the erase start pointer, and the cursor pointer position is set to the erase end pointer (S322). Then, the character data from the erasure start pointer to the erasure end pointer is deleted to pause (S323), and the erased character string is displayed on the screen (S324).
If the line scroll amount is larger than 0 (S305, Yes), the display length from the line head to the erase start pointer is compared with the line scroll amount. If the amount of scroll at the beginning of the line is smaller than the display length from the beginning of the line to the erase start pointer (S306, Yes), the erase start pointer is substituted into the erase start pointer SAVE (S308), and the erase start pointer is shifted by one character in the direction of the line. (S310). Then, the display length from the beginning of the line to the erase start pointer is compared with the amount of scrolling at the beginning of the line. This process is repeated, and if the amount of scroll at the beginning of the line is greater than the display length from the beginning of the line to the erasure start pointer (No in S306), a message is displayed asking the operator whether to erase the part beyond the displayable range. (S307) and waits for an instruction from the operator (S309). FIG. 16 shows an example of this message. If the instruction from the operator is to erase out of the display range (S311, Yes), the process proceeds to step S313.
[0071]
If the instruction from the operator is not to erase out-of-range (S311, No), FFH is set in the flag 2 not to be out-of-range erased (S312). Then, the value of the erase start pointer SAVE is substituted for the erase start pointer (S313), and the character data from the erase start pointer to the erase end pointer is deleted, and the interval is skipped (S314). Changes in display on the screen at this time are shown in FIG. 13 or FIGS. 17 (a), 17 (b) and 17 (d). When setting with line feed insertion (S315, Yes), a line feed code is inserted at the position where the cursor pointer is located (S316), and the line is inserted next to the line feed code where the cursor pointer is inserted (S317), and a line feed code is inserted. The completed character string is displayed on the screen (S318). The change in display on the screen at this time is shown in FIG.
[0072]
If it is not set to insert line feed, the process proceeds to step S318, and the erased character string is displayed on the screen (S318). Next, when FFH is set in the flag 2 that is not erased outside the display range (S319, Yes), the erase in the head of the line ends.
[0073]
If the flag 2 not to be erased outside the display range is not FFH (No in S319), it is determined whether or not the character string to be erased is temporarily displayed (S320). When the character string to be erased is temporarily displayed (S320, Yes), the screen is displayed for a predetermined time (S321). The change in display on the screen at this time is shown in FIG. If the character string to be deleted is not temporarily displayed (S320, No), the process proceeds to step S322. Changes in the screen at this time are shown in FIGS. Next, the line head position is set in the erase start pointer, and the cursor pointer is set in the erase end pointer (S322). Then, the character data from the erasure start pointer to the erasure end pointer is deleted to pause (S323), and the erased character string is displayed on the screen (S324).
[0074]
With the above processing, the operator can delete only the character string displayed on the display device 10, and the range that is not necessary is not deleted by mistake. Further, by inserting a line feed code, the front and back of the erased character string become clear, and the operability is improved. Further, when the operator deletes a character string that is not displayed on the display device 10, the operator can delete the end of the line or the beginning of the line while checking the deleted range. Furthermore, since it is confirmed with the operator whether or not the character string that is not displayed on the display device 10 is to be erased, the erasure can be canceled even if there is an erroneous operation by the operator.
[0075]
It is also possible to program the processing described above and record the program on a medium.
[0076]
[Embodiment 2]
Since the hardware configuration of the information processing apparatus in the second embodiment is the same as that of the information processing apparatus in the first embodiment shown in FIG. 1, detailed description will not be repeated. Also, the document buffer, various pointers and various flags shown in FIG. 2B and the processing procedure shown in the flowchart of FIG. 3 are the same, so detailed description will not be repeated.
[0077]
18 and 19 are flowcharts showing the processing procedure of S104 in FIG.
[0078]
First, the cursor pointer is set as the erase start pointer (S400). If the cursor pointer is on the line feed code (S401, Yes), the next position of the line feed is set in the erase end pointer (S403), and the character data from the erase start pointer to the erase end pointer is deleted to pause ( In step S416, the erased character string is displayed on the screen (step S417). That is, only the line feed code is deleted.
[0079]
If the cursor pointer is not on the line feed code (S401, No), it is determined whether or not the flag that does not delete the return line is FFH (S402). If the flag for not erasing the return line is not FFH (No in S402), the position of the line feed code is set in the erase end pointer (S414), and the character data from the erase start pointer to the erase end pointer is deleted to pause ( In step S416, the erased character string is displayed on the screen (step S417). That is, the part from the cursor position to before the line feed code is deleted.
[0080]
If the flag for not erasing the folded line is FFH (S402, Yes), the cursor pointer is set to the erasure end pointer (S404). If the display length from the beginning of the line to the end of the line is smaller than the screen size in the digit direction (S405, No), the position of the line feed code is set in the erase end pointer (S414), and the character data from the erase start pointer to the erase end pointer is deleted. Then, the interval is filled (S416), and the erased character string is displayed on the screen (S417). That is, the part from the cursor position to before the line feed code is deleted.
[0081]
If the display length from the beginning of the line to the end of the line is greater than the digit direction screen size (S405, Yes), it is determined whether the display length from the beginning of the line to the cursor pointer is greater than the digit direction screen size (S406). If the display length from the beginning of the line to the cursor pointer is larger than the screen size in the digit direction (S406, Yes), the position of the line feed code is set in the erase end pointer (S414), and the character data from the erase start pointer to the erase end pointer is stored. After deletion, the interval is cleared (S416), and the erased character string is displayed on the screen (S417). That is, the part from the cursor position to before the line feed code is deleted.
[0082]
If the display length from the beginning of the line to the cursor pointer is smaller than the digit direction screen size (S406, No), the display length from the beginning of the line to the erase end pointer is compared with the digit direction screen size (S407). If the display length from the beginning of the line to the erase end pointer is smaller than the screen size in the digit direction, the erase end pointer is shifted by one character toward the end of the line (S409). Then, the display length from the beginning of the line to the erase end pointer is compared with the screen size in the digit direction again (S407). This process is repeated, and when the display length from the beginning of the line to the erasure end pointer becomes larger than the screen size in the digit direction, a message is displayed asking the operator whether or not to erase after the return displayed on the next line (S408). Waits for an instruction from the operator (S410). An example of the message at this time is shown in FIG. If the instruction from the operator is to erase after the return (S411, Yes), the line feed code position is set in the erase end pointer (S414), and the character data from the erase start pointer to the erase end pointer is deleted. After the interval (S416), the erased character string is displayed on the screen (S417). That is, the part from the cursor position to before the line feed code is deleted. Changes on the screen at this time are shown in FIGS.
[0083]
If the instruction from the operator is not to be erased after the return (S411, No), the character data from the erase start pointer to the erase end pointer is deleted and a gap is made (S412). The changes on the screen at this time are shown in FIGS. 23 (a), (b) and (d). When the setting with line feed insertion is set (S413, Yes), a line feed code is inserted into the cursor pointer (S415). When the setting with line feed insertion is not set (S413, No), the erased character string is displayed on the screen. (S417). FIG. 20 shows a change on the screen when no line feed code is inserted, and FIG. 21 shows a change on the screen when a line feed code is inserted.
[0084]
24 and 25 are flowcharts showing the processing procedure of S105 in FIG.
[0085]
First, the cursor pointer is set as the erase end pointer (S500). If the cursor pointer is at the beginning of the line (S501, Yes), the process ends.
[0086]
If the cursor pointer is not at the beginning of the line (S501, No), it is checked whether or not the flag that does not erase the folded line is FFH (S502). If the flag for not erasing the return line is not FFH (No in S502), the line head position is set in the erase start pointer, and the cursor pointer is set in the erase end pointer (S513). Then, the character data from the erasure start pointer to the erasure end pointer is deleted and paused (S515), and the erased character string is displayed on the screen (S518).
[0087]
If the flag that does not erase the return line is FFH (S502, Yes), the cursor pointer is set to the erase start pointer (S503), and the display length from the beginning of the line to the cursor pointer is compared with the screen size in the digit direction (S504). If the display length from the beginning of the line to the cursor pointer is smaller than the screen size in the digit direction (S504, No), the position of the beginning of the line is set as the erase start pointer, and the cursor pointer is set as the erase end pointer (S513). Then, the character data from the erasure start pointer to the erasure end pointer is deleted and paused (S515), and the erased character string is displayed on the screen (S518).
[0088]
If the display length from the beginning of the line to the cursor pointer is larger than the digit-direction screen size (504, Yes), the display length from the beginning of the line to the erase start pointer is compared with the digit-direction screen size (S505). If the display length from the beginning of the line to the cursor pointer is larger than the screen size in the digit direction (S505, Yes), the value of the erase start pointer is substituted for the erase start pointer SAVE (S507), and the erase start pointer is one character in the direction of the line head. Shift (S508). Then, the display length from the beginning of the line to the erase start pointer is compared with the screen size in the digit direction (S505). If this process is repeated and the display length from the beginning of the line to the cursor pointer becomes smaller than the screen size in the digit direction (S505, No), a message asking the operator whether or not to erase before the wrapping displayed on the previous line is displayed. Display (S506) and wait for an instruction from the operator (S509). An example of the message at this time is shown in FIG. If the instruction from the operator is to be erased before returning (S510, Yes), the line head position is set to the erase start pointer, and the cursor pointer is set to the erase end pointer (S513). Then, the character data from the erasure start pointer to the erasure end pointer is deleted and paused (S515), and the erased character string is displayed on the screen (S518). Changes on the screen at this time are shown in FIGS.
[0089]
If the instruction from the operator does not erase after the return (S510, No), the value of the erase start pointer SAVE is substituted for the erase start pointer (S511), and the character data from the erase start pointer to the erase end pointer is deleted. Then, the interval is closed (S512). Changes in the screen at this time are shown in FIGS. 29 (a), (b) and (d). When setting with line feed insertion (S514, Yes), a line feed code is inserted at the position where the cursor pointer is located (S516), and after the line feed code where the cursor pointer is inserted (S517), The character string is displayed on the screen (S518). The change on the screen at this time is shown in FIG.
[0090]
If it is not the setting with line feed insertion (S514, No), the erased character string is displayed on the screen and the process ends (S518). The change on the screen at this time is shown in FIG.
[0091]
With the above processing, when the operator erases to the end or the beginning of the line, the apparent end of line or the beginning of the line on the display device 10 is erased. Can be prevented. Further, since the front and rear of the erased character string are divided by the line feed code, the front and rear of the erased character string become clear, and the operability of the subsequent editing work is improved. In addition, since the operator confirms whether or not to erase the next line that has been turned back or to erase the line before turning back, even if there is an erroneous operation by the operator, it is possible to cancel the deletion.
[0092]
[Embodiment 3]
Since the configuration of the information processing apparatus in the third embodiment is the same as that of the information processing apparatus in the first embodiment shown in FIG. 1, detailed description will not be repeated. Also, the document buffer, various pointers and various flags shown in FIG. 2B and the processing procedure shown in the flowchart of FIG. 3 are the same, so detailed description will not be repeated.
[0093]
FIG. 30 is a flowchart showing the processing procedure of S104 in FIG.
First, the cursor pointer is set as the erase start pointer (S601). If the cursor is on the line feed code (S602, Yes), the next position of the line feed is set in the erasure end pointer (S603), and 00H is set in the line feed insertion flag (S605). Then, the character data from the erasure start pointer to the erasure end pointer is deleted to close the gap (S611).
[0094]
If the cursor is not on the line feed code (S602, Yes), the cursor pointer is set to the erase end pointer (S604), and it is checked whether or not the line where the cursor is is a natural line feed (S606). If it is a natural line feed (S606, Yes), FFH is set in the line feed insertion flag (S607). If it is not a natural line feed (S606, No), 00H is set in the line feed insertion flag (S608).
[0095]
If the display length from the beginning of the line to the erasure end pointer is smaller than the one line size in the digit direction (S609, No), the erasure end pointer is shifted by one character toward the end of the line (S610). Then, the display length from the beginning of the line to the erase end pointer is compared with the size of one line in the digit direction. This process is repeated, and if the display length from the beginning of the line to the erasure end pointer is larger than the size of one line in the digit direction (S609, Yes), the character data from the erasure start pointer to the erasure end pointer is deleted to fill in ( S611).
[0096]
If FFH is set in the line feed insertion flag (S612, Yes), a line feed code is inserted into the cursor pointer (S613). The change on the screen at this time is shown in FIG. If 00H is set in the line feed insertion flag, the erased character string is displayed on the screen without inserting the line feed code into the cursor pointer (S614).
[0097]
With the above processing, when erasing in the line end direction is performed, a line feed code is inserted immediately before the folded character string, so that subsequent lines are not carried forward. Therefore, even if one line in the document is one line on the display device 10, the same operation as erasing up to the end of the line can be performed, and the operation can be unified.
