Set to B. In this case, the cursor pointer becomes message length +1. Next, in block 13, it is determined whether there is an additional message. If this determination is Y, as in block 14, an additional message is set in the incoming cover sofa IB. On the other hand, in the case of N, block 14 is skipped. Note that in the first flow, f
= J addition message does not exist, so it will always be N.

Then, as in block 15, the display buffer LCD
To B, the additional message and the contents of the line buffer LB are combined using the maximum input characters. In this case, the display will show "Find word?" and a filled-in mark corresponding to the maximum number of characters that can be input, and the rest are spaces. For example, the display in this case is as follows. In addition,
indicates the cursor.

” Find word? 1llllllllllll
llalllll ”Here, if you input the character moon as in block 16, this character will be stored in the cover sofa.Next, when C0DE+F is pressed,
The input character "moon" is stored in a storage area as shown in block 17, and search processing is further performed as shown in block 18. Next, as in block 19, whether or not the previously inputted word to be searched is accurate is considered to be the presence or absence of an error, and it is determined whether or not there is an error. If this determination is N, a correct search is possible, so the result is displayed on the display section as shown in block 20, and then the flow is ended.

The results are, for example, the number of lines and sentences containing the word "moon" to be searched, and one example is the following display.

” 4<] any 5tar, The moon
”On the other hand, if the judgment of block 19 is Y, block 2
1, an error message is displayed on the display.

An example of this error message is as follows.

“<l moon ff1l!I!all-II NO
T FOIIND C>The error conditions in this case are that the word to be searched does not exist in the file and that the word to be searched is empty.

Then, as in block 22, press the escape key ES
It is determined whether or not C has been pressed. If this determination is N, this flow ends.

If this judgment is Y, block 1 will be displayed in response to pressing ESC.
Return to step 1 and repeat the flow from the second time onwards.

In the second flow when the escape key ESC is pressed, if the cause of the error needs to be corrected, the correction is made here. Now, the storage area LIIA stores the previous input content amount oon as an additional message, and block 15 stores the content of the search inquiry screen as shown below in the display buffer, and displays it again as shown below. displayed above the section.

” Find word ? moon 111111
1111111 "C0DE even after the third flow
Press +F to display the search inquiry screen.

” Find word 7 moon 1llil
When C0DE+F is pressed to search for a line containing 'moon' again on 'ffll1st', the search process is performed and, for example, the following display is obtained on the display.

” 1<J in the moon, But lo
ng", the search flow will start by repeatedly inputting C0DE+F, and the search process will be executed as many times as necessary.
Everything in the text is searched.

Next, a replacement mode for replacing the word searched as described above with some new word will be described.

Replacement (Rep) in the word processor according to the present invention
The processing operation for the (lace) command is executed as follows using a flow similar to that for the search. When you enter a replacement command (by pressing the code key C0DE and letter key R at the same time: hereinafter abbreviated as C'ODE+R), a replacement inquiry screen (Replace WoDE) will appear on the display.
rd? ) appears, at the same time 1 corresponding to the number of effective characters appears.
For example, 0 filled marks ■ are displayed as shown below.

” 1leplace word ?Il[1lllll
Here, as an example of explanation, an example in which the word "'Country" is replaced with "Naguchi on I+" will be described.

Then, press the key to input the word (old word) "Country" to be replaced. Then, similar to the inquiry screen for searching, the following display will appear.

”Replace word?Country
Next, press the carriage return key C/R, which also serves as the accept key, and a new word inquiry screen (New Word?) will appear.
For example, the following display will appear.

"New word ?■■--11118■--"
Then, press the new word "Nation" and get the following display.

"Neu word? Nation II■II
II ``Here, press the carriage return key C/R, and a screen will appear on the display asking whether you want to replace all words or just one word, as shown below.

"ReplceAll -Y/N?" Y means to replace all target words after the cursor position in the file, and N means to replace only one word after the cursor position.

Therefore, by pressing the character key Y or N and then pressing the carriage return key C/R, a predetermined operation is executed and the result is displayed. After that, it returns to the initial state.

The error conditions in this mode are that the word to be replaced does not exist, the replacement process resulted in memory overflow, and the word to be replaced is empty. In this case, an error message or Make announcements.

As described above, according to the word processor of the present invention, when an error occurs when inputting processing commands such as search and replace, by displaying the input content that caused the error,
The modification can be easily implemented. In addition, this correction does not have to be done entirely, but only a part of the error needs to be corrected, which improves usability.

Although the preferred embodiment has been disclosed, it will be apparent to those skilled in the art that many modifications and variations can be made within the scope of the invention.
