Abstract

PURPOSE:To attain a display where a corrected character string can be distinguished from others by adding automatically the attribute information to show that the correction is given to a character string after this string is changed in a change mode of character strings. CONSTITUTION:In an editing mode the input of a key is carried out through an input part 14 and a CPU 10 decides the type of the key. then the editing process is branched into each job according to the type of the key. For instance, an inserting process is carried out when an insertion key is operated. In this insertion mode the character codes supplied from the part 14 are stored in an input buffer 26. When an execution key is operated to show the end of input of characters, the contents of the buffer 26 are put into the character data stored in a document buffer of a document memory part 28. Then the result of this editing is displayed at a display part 20. Here a corrected area display key is operated and display a corrected area with high luminance.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to the g-to system in information equipment such as Japanese word processors having a document creation function, and in particular, the modified portions are not modified. The present invention relates to a method for displaying modified parts in a manner that allows them to be distinguished from other parts.

E. Prior art and its problems] Conventionally, in an information device such as a Japanese word processor that has a document creation function, when document data stored in an external storage device, etc. is read out and edited. Correspondence data can be modified using functions such as , deletion and insertion. However, in this case, it is difficult to distinguish between the modified character string and the original (unmodified) character string on display. Therefore, even when the user wants to reconfirm only the corrected character string, he or she has to search for the corrected character string in the document displayed on the display device.゛[Objective of the Invention] The present invention has been made in view of the above points, and it is possible to distinguish, on display, a character string that has been modified and a character string that has not been modified, when document data is edited. The purpose of this invention is to provide a method for displaying modified parts in a manner that allows users to obtain the corrected information.

[Summary of the Invention] In order to achieve the above object, the present invention automatically adds attribute information indicating that a modification has been made to the changed character string when a character string is changed. , when a request is made to display the seven modified sentences separately from other strings, it is possible to distinguish only the strings with the above attributes from other strings. The feature is that it is displayed on the screen.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows its configuration, and 10 is a central processing unit (
12 is a program storage section. The program storage section 12 is a RAM or ROM, and the programs stored therein are executed by the CPU10 to control each section. 14 is f! for character keys and deletion, insertion, etc. This is an input section including an 8th set key for instructing the set. The input unit 14 also has a "modified part display" key for instructing to display the character string of the modified part separately from other parts.

16 is a display memory, 18 is a display control section, and 20 is a display section. The display memory 16 has a character code section and an attribute information section for each character to be displayed on the display section 20. When a character code is written in the character code section of the display memory 16 and an attribute is written in the attribute information section, the display control section 18 writes the character code to the position on the display section 20 corresponding to the write address. In addition to displaying the corresponding character shape, it is also possible to instruct high brightness display in the RI information section according to attribute information.

22 is a printing control section, and 24 is a printing section.

These are for printing documents.

26 is an input buffer, and 28 is a document storage section.

The input buffer 26 is a RAM, and the input buffer 26 is a RAM.
The character code input from 4 is stored. The document storage unit 28 is for storing document data in order to save created documents. Further, the document storage section 28 is a document buffer in which document data currently being created or edited is stored. (not shown).

30 is a work area. This work area 30 is a RAM and contains various pointers used when executing the above program.

The operation of the device having such a configuration will be explained below with reference to FIG. That is, FIG. 2 shows the display screen of the display section 20, and FIG. 2(a) shows document data successively output from the wording storage section 28. In this state, if the character string "Aiu" is inserted at the cursor position (indicated by an underline "-" in the figure), the result will be as shown in (1) in the figure. Furthermore, move the cursor to the same figure (C
) If the three characters are corrected to rXYZJ from the position shown in (d) of the same figure, the result will be as shown in (d).

Here, when the "display corrected part" key of the input section 14 is operated, the corrected part is displayed with high brightness (indicated by the diagonal line in the figure), for example, as shown in FIG. 4(e).

Such an operation will be further explained using the flow chart of FIG. In this case, it is assumed that you are already in edit mode. That is, when a key input is made from the input unit 14 (step 5T301), the type of the key is determined and the process branches to step 5T302> and each editing process.

The following will explain the case of insertion as an example. That is, when the "insert" key is operated, the process branches to insertion processing. In this insertion process, first, when a character code is input from the input section 14, it is input into the input buffer? 26 (step 5T303).

Here, when the ``execute J'' key indicating the end of character input is operated, the contents of the input buffer 726 are inserted into the document data in the document buffer of the document storage section 28 (step 5T304).

Then, the editing results are displayed (Stellaf S-30
5).

Also, the key input in step 5T301 above is “
If it is the "Display modified portion" key, the modified characters are displayed with high brightness (step ST'306).

Before going into details of each step, the structure of the document data in the document buffer of the document storage section 28 will be explained in the fourth section.
This will be explained using figures. That is, as shown in the figure, information for one character in the document buffer 32 is composed of two words, the first word being attribute information and the second word being a character code. 1
A word consists of 16 bits. The character code is J
Expressed in fsc6226. Generally, underlining, shading, etc. are added as attribute information, but for the sake of simplicity, here, for simplicity, it is assumed that such information is not provided and only the modification attribute is provided.

Figure 5 shows the structure of the above attribute information.
When is "1", the character to which this attribute information is added is
Indicates that the character has been modified. Further, when bit O is "0", it indicates that the character to which this attribute information has been added is a character that has not been modified.

Generally, word processors have functions such as line breaks and page breaks. Also in this example, JISC6
Either set a special code in the code area outside the 226 kanji code and store this code in the character code area of the document buffer 32, or set a line break or a line break in the empty bit of the attribute information.
By providing bits to express page breaks, etc.,
Although these functions can be realized, the explanation of these functions will be omitted for the sake of brevity.

Next, each step in FIG. 3 will be explained using the case of insertion as an example. The above step 5T303, ie, character input processing, is shown in rough detail in the flow chart of FIG. However, in the figure, IRP.

IWP is the above work IA! 30, IRP is a pointer for reading the contents of the input buffer 26, and IWP is a pointer for writing the character code input to the input buffer 26.

That is, the input buffer 26 is cleared using IRP and IWP as the start address of the input buffer 26 (Stellaf S
Ding6o1). Then, a kanji code is input by key input (step 5T602). Here, if the "execute" key instructing execution of the insertion process is operated (step 5T603), the character input process is ended. ``If it is not the execution J key, it is a character code, so set that code to the address indicated by the contents of JWP (step 5T604), and increment JWP (
Step 5T605).

The above step 5T304, ie, the insertion process, is shown in more detail in the flow chart of FIG. However, in the figure, TPD, TPS, and LDP.

Each STP is a pointer for transferring document data. CUR indicates the address of document data corresponding to the cursor position indicating the insertion position. ATBtJ
F and CDBUF are buffers for temporarily storing attribute information and character codes during the process of editing a document. DSIZE indicates the length (word count) of the current document data.

That is, the transfer destination pointer (TPD) is set to the document buffer 32.
The final address is set to R (step 5T701), and the transfer source pointer (TPS) is set to the final address of the document data. That is, TPS is set as the start address of the document buffer 32, DSIZE is added to it, and the address obtained by subtracting "1" is set in TPS (step 5T702). Then, the transfer is repeated while TPD and TPS are decremented until the attribute information and character code of the cursor position (CUR) are transferred. That is, if the address set in TPS is smaller than the address set in CUR (step 5T703), data at the address indicated by the contents of TPS is transferred to the address indicated by the contents of TPD (step 5T704). Then, TPD and TPS are decremented (step 5T705).
, the process returns to step 5T703. This step 5T7
03 to 5T705, the data in the document buffer 32 in the state shown in FIG. 8(a) is changed to the state shown in FIG. 8(b).
Transferred as shown in .

If the address set in TPS becomes equal to the address set in CUR (step 5T703), the read pointer (LOP) and write pointer (STP) are initialized. That is, set the address set in CUR to STP (step 5T706), and set T to LDP.
An address that is "1" larger than the address set in the PD is set (step 5T707). by this,
Both pointers are set as shown in FIG. 9(a).

In this state, it is checked whether or not there is an unprocessed character code in the input buffer 726. That is, I.W.
Check whether the address set in P is greater than the address set in IRP (step 5T
708).

If there is an unprocessed character code, is it an attribute information buffer? (A
Set r (0001)t 6 J in TBUF),
The code read from the input buffer 726 is then set in the character code buffer (CDBUF) (step 5T709). At this time, the value set in ATSUF is
This attribute indicates that there has been a modification. Then, the read pointer IRD is updated (step 5T710), and the length of the document data (DSIZE) is updated (step 5T211).

Further, if it is determined in step 5T708 that there is no unprocessed character code, the read pointer (LDP
), and set them in ATBUF and CDBUF, respectively (step 5T7).
12). After that, update LDP (Stellaf S-71
3).

Through the above steps, attribute information and character codes are set in ATBUF and CDBUF, respectively. Next, write the contents of ATBUF and CDBUF using the write pointer (S
TP> position (step 5T714), !
The inclusion pointer is updated (step 5T715). Then, it is checked whether the read pointer has exceeded the end of the document data (Stellaf S 716), and if it has not, the process from step 5T708 onward is repeated, and if it has exceeded the end, the process ends.

For example, "A" is stored in the input buffer 26.

Assuming that character codes for the three characters "i" and "u" are included, the states of the document buffer 32, STP, and LOP when these character codes have been processed are shown in Figure 9 (b).
).

When the input buffer 26 becomes empty, the document data is transferred in steps 5T712 and 5T713, and the state of the document buffer 32 when the process ends in step 5T716 is shown in FIG. 9(C). It becomes like this.

As described above, the character code in the input buffer 726 and the modified attribute information automatically added to the character code are inserted into the original document into the document data.

Furthermore, in step 5T305, that is, the display process, since the result of the insertion process is present in the document buffer 32, the editing result is displayed on the display section 20 accordingly.

The above step 5T306, that is, the correction part display process is a process that is started by operating the "display correction part" key of the input section 14, and is a process that is started by operating the "display correction part" key of the input section 14, and is a process that is started by operating the "display correction part" key of the input section 14. High-intensity display of characters in
Characters with unmodified attribute information have low I! Display in i degrees.

The above explanation took the case of insertion as an example, but deletion,
The same applies to corrections, etc., so no particular explanation will be provided.

In this way, when editing document data, insert.

When a correction is made using a function such as deletion, attribute information indicating that the correction has been made is automatically added to the correction part, and when a request to display the correction part is made, the above attribute information is automatically added. Only the corrected character strings that have been added are displayed in a high-intensity display, etc., making it easier to check the corrected parts, which has the effect of discovering correction mistakes.
At the same time, the labor burden on the operator can also be reduced.

In addition, in the above embodiment, a "modified part display" key is provided,
By operating this key, the modified parts are displayed in high brightness, but for example, when the key to instruct the end of document editing (referred to as the "End" key here) is operated, the modified parts are automatically displayed. It may also be highlighted.

In addition, in the above embodiment, attribute information indicating that there is a modification is added to the modified part, but if this is cleared when registering the document, the next time the same document is edited. In some cases, you can highlight only the parts that were corrected at that time.

[Effects of the Invention] As detailed above, according to the present invention, when document data is edited, a modification is made so that a character string that has been modified and a character string that has not been modified can be distinguished in terms of display. A location display method can be provided.
