Abstract

(57) [Summary] [Purpose] At the stage when new data is input during editing, etc., only the display based on the input is performed, and unnecessary editing and rewriting work is not performed. [Structure] When a series of document data stored in a document memory 8 is edited such as inserting characters, the chaining of documents is different from the normal chaining structure based on the editing position. Chained with a special chaining structure,
At the editing position, the data before editing and the data after editing are separately stored and held. After that, when the edited contents are fixed and the normal chained structure is set, any one of the separately stored data is selected and returned to the normal chained structure.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data display method for newly inputting data displayed on a display screen.

[0002]

2. Description of the Related Art Recently, word processors to which various functions are added have been proposed in order to improve the editing function of word processors. For example, as a page management function, a function of displaying a previous page or a next page of a document displayed on a display screen so that a desired page can be called immediately is known. In document editing, the document proofreading or editing function is extremely important in order to adjust the appearance of the document and determine the arrangement of words. However, if the character string is corrected, added or deleted, the following There is a problem that the word arrangement on the page changes significantly.

[0003]

The above-mentioned problems will be described with reference to FIG. 6. In FIGS. 6 (a) and 6 (b),
Reference numerals 2 and 3 denote first to third pages on a display screen such as a CRT, 1a denotes a boundary between the first page and the second page, and 2a denotes a boundary between the second page and the third page. Is. Now, as shown in FIG. 6 (a), the sentence "The document has been edited." Is written on the last line of the first page 1 and the second line from the last line. four rows of text 2 _1, 2 _2, 2 _3, 2 _4, as the third-page 3 sentence 3 ₁ of two rows, 3 ₂ are described, for example, the cursor position indicated by "statement," " Insert string "
If the five characters are changed, the character "ta." That pops out from the last line of the first page 1 comes to the first line of the second page 2 as shown in FIG. 6 (b). The sentences 2 ₁ , 2 ₂ , and 2 ₃ from the 1st line to the 3rd line remain on the 2nd page, and the sentence 2 _{4 on} the 4th line moves to the 1st line on the 3rd page. That is, due to the proofreading such as addition or change of characters in the text, the boundary of the page has changed from that shown in FIG. 6 (a) before the editing or proofreading, and the arrangement of the characters on each page after the proofread position Is one or more lines off from the state before proofreading, so the number of pages and lines of the same character string before editing or proofreading are different from the document after editing or proofing, so when editing next There was a drawback that it was difficult to find the character string.

During this editing or proofreading, a rewriting process for sequentially shifting the character arrangement on each page after the proofreading position must be repeated every time the above editing or proofreading is performed. There was a problem that it took time to work and high-speed editing processing could not be performed.

Moreover, when editing such as inserting new data, the rewriting work based on this editing is performed on the document data itself in the original document memory. Therefore, after this rewriting, There was a problem that the document data before editing could not be restored.

An object of the present invention is to newly input data by making only display based on the input when new data is input in editing or the like, and avoiding unnecessary editing and rewriting work. When canceling data,
It is to be able to immediately return to the display state before data input.

[0007]

The means of the present invention are as follows. A data display method for newly inputting data to the data displayed on the display screen, wherein a series of data stored in a predetermined storage means is sequentially read and displayed on the display screen. When data is newly input at a position arbitrarily designated in the series of data displayed on this display screen by controlling the display, the newly input data is made to correspond to the designated position, and When the newly input data is stored and stored separately from the storage content in the storage means, the above-mentioned data is displayed at the display position corresponding to the designated position among the series of data displayed on the display screen. Display control is performed to display the separately stored data, and when returning to the state before the new data is input, the storage of the separately stored data is erased and Data display method being characterized in that so as to display control so as not to display the data displayed on the designated position on the display screen is.

[0008]

The operation of the means of the present invention is as follows. It is assumed that a series of data stored in a predetermined storage means is sequentially read and displayed on the display screen, and in this state, the series of data displayed on the display screen is arbitrarily selected. When data is newly input at the designated position, the newly input data is stored and held separately from the storage content in the storage means in association with the designated position and stored in the storage means. Data rewriting work, that is, updating work is not performed on the contents. Further, at this time, since it is necessary to display the data on the display screen, when displaying the newly input data, in the series of data displayed on the display screen, the data is displayed at the designated position. At the corresponding display position, display control is performed so that the separately stored data is displayed. After this, there is a case where it is necessary to cancel the data thus input, that is, there is a case where it is necessary to return to the state before the input of the new data. In that case, the storage of the separately stored data is erased, and the display control is performed so that the data displayed at the designated position on the display screen is not displayed.

Therefore, at the stage when new data is input in editing or the like, the input data is separately stored and held so as to be displayed at the display position corresponding to the input position. It is possible to avoid unnecessary editing and rewriting work for the means.

Further, after this, when newly input data is to be canceled, it is possible to immediately return to the display state before data input by simply deleting the contents of the separately stored data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. (1) Configuration FIG. 1 is a block circuit diagram of a word processor of the present invention. In FIG. 1, 4 is a key input unit, 5 is a key code analysis unit, and performs code analysis of a key pressed by the key input unit 4. On the basis of the key code given to the document edit control unit 7 and the document management unit 6, the document edit control unit 7 takes in the data from the document management unit 6 and the data in the document memory 8 and displays it through the display control unit 9. Document data is displayed at 10.

2 (a) and 2 (b) show the document memory 8 of the present invention.
3 shows a memory chain structure before and after editing / proofreading in FIG. Figure 2 (a) shows the chain structure before editing / proofreading.
Reference numeral 1 denotes a base pointer, and 12a, 12b, 12c, 12 having information for sequentially pointing to the next row block.
Information indicated by d and 12e is a line block in which one line of each sentence is a block unit and indicates the memory from the first line to the fifth line, and information indicating the base pointer 11 and the line next to each line block. 11a, 11b, 11c, 11d, 11
e and 11f sequentially connect the first line to the fifth line of the document in a chain form as shown by the arrows, and sequentially display the document as 1, 2, 3, 4, 5 lines on the display screen. Read and read.

FIG. 2B shows a structure in which a row is added to the row block 12b of the second row by inserting it in the chain structure before editing / proofreading described above. The same parts as those of FIG.
When the proofreading is performed, the editing / proofreading pointer 13 is created. The edit / correction pointer 13 has the head information 1 of the new block chains 14a, 14b, 14c after the edit / correction.
4X, new line blocks 14a, 14b, 1 after editing / calibration
4c has edit / correction start character position information 14Y, edit / correction new line blocks 14a, 14b, 14c edit / correction end character position information 14Z, and the beginning of the old line block chain 12b before edit / correction. Information 12X, edit
It has edit / correction start character position information 12Y of the old line block 12b before proofreading and edit / correction end character position information 12Z of the old line block 12b before edit / proofreading. Also, edit
The proofreading pointer 13 holds the leading edge information 12W of the next row block 12c which has no influence on the editing / proofreading.

Reference numerals 14a, 14b and 14c denote new row block chains, which are read and chained based on the information indicated by 14X, 14Y and 14Z. Incidentally, 11
c ', 11c "and 11c" are address information pointing to the next new block. Old line block chain 12
b is also read and chained based on the information indicated by 12X, 12Y, 12Z described above, and the row blocks 12c, 12d, 12e that have no influence on the editing / correction are chained by the information indicated by 12W. . Reference numeral 15 indicates row block end information. (2) Chain Operation The row block chain operation at the time of editing / calibration described above will be described with reference to the flowchart shown in FIG. First, when the edit / calibration start 16 is performed, the edit / calibration start position is input 17. Now consider the case where the second row is increased by two rows by the insertion. An edit / proof pointer is secured 18 in the memory of the document memory 8 and the edit / proof pointer 13 is set in the first row block 12a and the second row block 12b as shown in FIG. 2 (b).
Bond 19 between. Then, a new row block 2'is reserved 21 in the memory, the row block 2 is edited, and a new row block 2'is created 22. Thus, the new block 2'in which the character is inserted in the line block 2 is obtained in FIG. 2 (b).

Next, the row block 2'is connected to the edit pointer 23, and the detection 20 as to whether or not the edit end has been performed. If it is not the edit end, the line block 2 ″ that has increased as a result of the next character insertion is secured 21a in the same manner as above and the line block 2 ″ is the pointer of the line block 2 ′ of the preceding line together with the operation 22 of making a line block. Bind to. And such an operation 21a
23a to 23a are sequentially repeated to form a row block 2 "and are joined together. As a result, new row blocks 14a, 14b, 14c
Are held in memory. If the editing is finished, the block end information 15 is set 24 in the last row block indicated by the new row block 14c.

Next, the old block chain 1 that needs to be edited
The row block end information 15 is set 25 in the last row block of 2b. Next, the edit / proof pointer 13 points the old block 12b to the information 12X, 12Y,
Chain with 12Z etc. Further editing / proofing pointer 1
3 is set 27 to point to the row block 12c that has no effect on editing / proofreading, and editing / proofreading is completed 2
8. When the editing / proofreading is completed in this way, the memory block chain is completed as shown in FIG. 2B, and the document screen after editing / proofreading is controlled by the document management unit 6 shown in FIG. Take out and display.

In FIG. 3, the new block chain is set to 3 lines, but this is not limited to 3 lines, and the required number of times is set to 21.
Repeat a to 23a. In the above-described operation, the editing start position input 17 and the like is executed by being input from the key input unit 4. Incidentally, all of this execution is driven by an interrupt or the like. (3) Display Operation Next, the display when the display start command is input will be described with reference to FIGS. 4 and 5.

FIG. 4 shows a memory block chain structure after editing / calibration similar to FIG. 2 (b), and FIG. 5 is a flow chart for displaying the old and new block chains.

In FIG. 4, 29 is a display address pointer, and 30 is a display address pointer.
Is a flag for discriminating between old and new lines and is instructed from within the document management unit 6 shown in FIG. "1" is the new block 14a, 1
4b, 14c, etc. are selected, and "0" is a flag for selecting the old row block 12b, etc.

In FIG. 4, pointer information 11a, 11b, 11
c, 11c ', 11c ", 11c", 11d ... 11
The address added after f is "0" for the line information 31,
“1” indicates the edit / proof pointer information 32.

FIG. 5 is a flow chart of the display operation.
When the display start 33 is performed, the pointer 11 is set 34 for calculating the address of the row block 12a of the first row. When the setting is completed, the address calculation 35 of the next second row block is performed. In this case, the second line is replaced with the editing / proofreading pointer 13 and the search 36 for the line information "0" is "1". Is made. A flag is set so that the line information is "1" until the end of a new or old block is detected by detecting the editing proof pointer. Here, the detection 37 as to whether or not it is a new document is performed by the flag 30 from the document management unit 6. If "1" is set in this flag 30, it is considered that a new document is selected, and the new line block 1
The pointer address 11c 'of 4a is calculated 38, and it is detected 39 whether the new block is the end or not. If the new block is not the end in 39, the next pointer address 11c ″
Set the pointer for calculating
To do. Then, after line modification 41 (reverse printer, etc.) for display is performed, a new block 14 is displayed on the display screen of the CRT, etc.
The character display of the portion a, that is, the one-line screen display 42 is performed. Then, it is detected whether the one-screen display is the end. If it is not the end, 35 → 36 → 37 → 38 → 39 → 40
→ 41 → 42 is repeated on the new block 14b,
Each line of 14c is displayed. In addition, the last new bank block 1
In the display of 4c, when the row block end information 15 is detected in the new row block, a pointer set 44 is executed from the edit / calibration pointer 13 for calculating the address of the next row block. Then, the new block 14c is line-modified 41 and displayed 42.

Next, the row blocks 12c, 12d and 12e which have no influence on the editing / proofreading are 35 → 36 → 40 → 41 →
The lines are sequentially displayed one by one in the order of 42 → 43 → 35, the line block 12e detects the line block end information 15 (screen display end) 43, and the display operation ends 45. In the pointer set 44, the above-mentioned flag for ending the display of the new or old line is set to "0". By the flag "0", the display processing of the lines which have no influence on the editing / proofing is performed.

On the other hand, when it is detected that the document is the old document in the detection 37 of the new document or not (that is, if "0" is set in the flag 30), the edit pointer 13 is set to the old line block 12b.
Address calculation 46 is performed. Next, it is detected 47 whether it is the old block end, and if NO, 40 → 41 → 42
→ 43 → 35 → 36 → 37 → 46 → 47 The loop route is repeated. When the line block end information 15 is detected in the old block end detection 47, 47 → 44 → 41 → 4
After displaying the last old row block on the path of 2, the row blocks 12c, 12d, which do not affect the editing / correction on the path of 43 → 35 → 36 → 40 → 41 → 42 → 43, as described above,
Following 12e, these are sequentially displayed. Then, the row block end information 15 of the last row block 12e is detected and the process ends 45. (4) Document update operation To return the edited / proofreading document to the document before editing / proofreading, add a return address in the editing / proofreading pointer 13 and add a new block after erroneous editing / editing the proofreading pointer. The chains 14a, 14b and 14c are erased, the block 12b before editing / proofreading is directly chained to the portion where the editing / proofing pointer 13 is chained, that is, the row blocks 12c, 12d and 12e, and the editing pointer is deleted. . The result returns to the document before editing / proofreading shown in Fig. 3 (a). If the block chain before editing / proofreading is not required, the row block chain 12c before editing / proofreading,
It suffices to delete 12d and 12e, and directly chain the block chain after editing / proofreading to the document block to delete the edit pointer.

[0024]

According to the present invention, when new data is input in editing or the like, the input data is separately stored and held, and is displayed at the display position corresponding to the input position. Thus, it is possible to avoid unnecessary editing and rewriting work on the original storage means.

Further, after this, when newly input data is to be canceled, it is possible to immediately return to the display state before data input by simply deleting the contents of the separately stored data.
