In order to make it easy to understand, an outline of cursor movement control at the time of performing search / replacement processing for replacing all words with other words in the entire sentence will be described.

FIGS. 3 (a) to 3 (e) show the operation of the search key 7 and the LCD.
9 is a search / replace setting screen format data displayed on the display 11.

The number of characters of the search (search) character string and the number of characters of the replacement (replacement) character string can be input up to a maximum of eight characters. A field for displaying the input character string is called a setting item field.

When the search key 7 is operated, the cursor 30 is displayed after the setting item name "SEARCH?" As shown in FIG. When "Abc" is entered as a search character string, "Abc" is displayed in the setting item column as shown in FIG.
Is displayed, and the cursor 30 is displayed at the position next to the character "c".

Next, when the cursor moving (right) key 6 is operated to input a replacement character string, the cursor 30 is moved to the state shown in FIG.
Is displayed next to the setting item name "REPLACE?" When the character string "Bba" is input, "Bba" is displayed in the setting item column as shown in FIG. 3D, and the cursor 30 is displayed at the position next to the character "a".

After that, repeat the same operation to set item name "PAGE
"1" in the setting item column corresponding to "?", And the setting item name "L
"10" is entered in the setting item column corresponding to "INE?".

With the above operation, each data setting for the search / replacement process is completed, and the entire text from the 10th line on the first page of the text data specified by the operation of the execution key 8 is replaced with the character string "Abc". Everything is replaced by the string "Bba".

In FIG. 3D, when the cursor movement (left) key 6 is operated a plurality of times, the cursor 30 changes from the character "a" to the character "a".
.. Are displayed at the positions of “b”..., And the input characters can be corrected.

Next, a cursor movement control routine in the search / replacement process performed by the control device C of the electronic typewriter will be described with reference to the flowchart of FIG.

When the power is supplied to the typewriter, this control is started, and initial settings such as resetting of a search / replace mode flag are performed in step S1 (hereinafter, simply referred to as S1 and other steps are similarly handled). . Next S2
In S1, S2 is repeated until a key is input, and when a key is input, the process proceeds to S3.

In S3, it is determined whether or not the search and replace mode flag is set based on the data in the search and replace mode flag memory 27 of the RAM 20, that is, whether or not the search and replace mode is set. The process proceeds to S4 when No.

In S4, it is determined whether or not the operated key is the search key 7, and if it is not the search key 7, the process shifts to S19, the process corresponding to the operated key is executed, and the process returns to S2. When the search key 7 is operated in S4, the process proceeds to S5. In S5,
The search / replace mode flag is set, and the search / replace mode is set. In the next S6, a setting screen for the search / replacement process is displayed on the LCD display 11, and the process returns to S2. (See FIG. 3 (a).) S7 to S12 are steps for writing the input data into the line buffer 21 and sequentially moving the display position of the cursor 30. In S7, it is determined whether or not the character key 4 has been operated. If it is determined that the character key is not 4, the process proceeds to S13, and if it is the character key 4, the process proceeds to S8.

In S8, data input based on the data of the cursor position pointer 24 is written to the line buffer 21.
In this case, the main CPU 14 outputs the input data to the display CPU 10 via the interface 13, and the CPU 10 outputs this data to the LCD display 11, so that characters corresponding to the data are displayed.

In the next S9, it is determined based on the search / replace setting screen format data of the ROM 15 and the data of the cursor position pointer 24 whether or not the currently input setting item column is full. If it is not full, shift to S10. In S10, cursor display position memory
1 is added to the value of 23, and in S11, a cursor is displayed based on the data in the cursor display position memory 23,
Return to S2.

Steps S2 to S3 and S7 to S11 are repeated, input data is sequentially written to the line buffer 21, and the display position of the cursor 30 is sequentially moved and displayed. Then, when the predetermined number of characters is input in the setting item column, it is determined as Yes in S9, and the process proceeds to S12. In S12, the first value of the next setting item column is set in the cursor display position memory 23 based on the search / replace setting screen format data, and in S11, the cursor 30 is displayed based on the data in the cursor display position memory 23. And returns to S2.

S13 to S14 and S10 to S12 are steps for moving the display position of the cursor 30 by operating the cursor movement key 6.
In S13, it is determined whether or not the operated key is the cursor move (right) key 6. If the cursor is not the cursor move (right) key 6, the process shifts to S15.
In the case of, the process proceeds to S14.

In S14, based on the data in the line buffer 21 and the data in the cursor position pointer 24, it is determined whether or not there is data in the moving direction of the cursor 30.
After S11, the cursor 30 moves sequentially in the direction specified by the cursor movement key 6 and returns to S2. When there is no data, the cursor 30 is displayed at the first character position of the next item setting column via S12 / S11. And returns to S2. (See FIGS. 3 (b) and (c)) And S2 to S3 and S7 to S12 and S2 to S3 and S13 to S14 and S10
Steps S12 to S12 are repeated, and desired data is set in all the setting item columns displayed on the LCD display 11. (See FIG. 3 (e).) Further, S15 to S18 are steps for executing a search / replacement process. In S15, it is determined whether the operated key is the execution key 8 or not. Since it is a key operation that is not necessary for search and replacement processing, an alarm is displayed on the buzzer, alarm lamp, etc.
The process returns to S2, and shifts to S16 when the execution key is 8.

In S16, the data in each setting item column is written into the predetermined memories 25 and 26 based on the search / replace setting screen format data and the data in the line buffer 21. At this time, for example, the data in the search setting item column is written into the search word memory 25, and the data in the replacement setting item column is written into the replacement word memory 26.

In the next S17, in the specified text data,
A search / replacement process for sequentially replacing all character strings corresponding to the data in the search word memory 25 with character strings corresponding to the data in the replacement word memory 26 based on the data in the search word memory 25, the data in the replacement word memory 26, and the like. Is executed. In the next S18, the search / replace mode flag is reset, and the process returns to S2.

As described above, when there is no data in the cursor movement direction specified by the operation of the cursor movement key 6, the cursor 30 is displayed at the head position of the other setting item columns. Input can be performed quickly and easily, and the operability of the cursor movement key 6 is improved.

Although the above embodiment describes the cursor movement control in the search / replace processing, the present invention sets a print format having setting items such as a left margin, a right margin, a pitch feed, a tab position, and a line space in the memory mode. It is needless to say that the present invention can be applied to such cases.

Further, the above embodiment is an LCD display 1 capable of displaying two lines.
Although the electronic typewriter provided with 1 has been described, the present invention can be applied to a word processor or the like having a CRT screen.
