Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment of the present invention will be described using an interactive text editor 100 as an example of a device.

The interactive text editor 100 according to the embodiment of the present invention creates a text 301 using a code system that uses functional characters to distinguish between 1-byte codes and 2-byte codes in a character string in which 1-byte codes and 2-byte codes are mixed. Text reading means 1 to store in reading text buffer 201
01, a character string storage means 102 that stores in the buffer the 1-byte and 2-byte codes stored in the text buffer 201 by this text reading means 101, and the 1-byte and 2-byte codes stored by this character string storage means 102. a character string editing means 103 for editing the text using functional characters and storing the edited code in an editing buffer 204; and a display means 104 for displaying the edited code stored by the character string editing means 103 on a display 302; First code buffer that temporarily holds 1-byte code (1-byte code buffer) 20
2 and a second code buffer (2-byte code buffer) 203 that holds a 2-byte code are separately provided, and the 1-byte code of the text 301 stored in the text buffer 201 is stored in the character string storage means 102 as the first code buffer. The 2-byte code is transferred to the second code buffer (1-byte code buffer) 202, excluding function characters.
Bytecode buffer) 203 is provided.

Text writing means and other means not directly related to the present invention are omitted.

Text reading means 101 reads text 301 and stores it in text buffer 201.

The character string storage means 102 manually stores the text buffer 201 stored by the text reading means 101 while distinguishing it into a 1-byte code buffer 202 and a 2-byte code buffer 203.

The character string editing means 103 edits the 1-byte code buffer 202 and the 2-byte code buffer 203 stored in the character string storage means 102 and stores them in the editing buffer 204.

The display means 104 displays the editing buffer 204 stored by the character string editing means 103 on the display 302.

Next, the operation of the interactive text editor 100 according to the embodiment of the present invention configured as described above will be explained. FIG. 2 is a flowchart showing the flow of the operation.

The interactive text editor 100 stores the text in the text buffer 201 using the text reading means 101 when the text 301 is manually inputted and activated (step 501).

Next, manually read the text stored in the text buffer 201 one digit at a time (step 502), and check whether the character is a 1-byte code or a 2-byte code (step 503).
, determine whether it is a 1-byte code or a 2-byte code (step 504), if it is a 1-byte code, store it in the 1-byte code buffer 202 (step 505), and if it is a 2-byte code, store it in the 2-byte code buffer 203). Step 506), the end of the text is determined (step 507), and the character string storage means 102 is activated.

Next, check from the beginning of the 1-byte code buffer 202 (
Step 508) It is determined whether a character other than a blank space is stored.Step 509). If a character other than a blank space is stored, the character is stored in the editing buffer 204.Step 510
), otherwise it is checked from the beginning of the 2-byte code buffer 203 (step 511), and it is determined whether or not anything other than a blank space is stored (step 512), and if it is, the function characters KI and KO are stored in front. Correct the character while maintaining consistency with the stored character and store it in the editing buffer 204 (step 513), otherwise store a blank space in the editing buffer 204 (step 514), for the number of digits stored in the editing buffer 204. Shift the digit position of each buffer (step 515), determine whether the 1-byte code buffer 202 is finished (step 516), and if it is not the end, return to step 508; if it is the end, edit the buffer 202 The process ends at step 517).

Next, the status of each buffer is shown in Figure 3 (a), (b), (C
), (6), and (e).

A text buffer 31 is input and stored separately in a 1-byte code buffer 32 and a 2-byte code buffer 33,
When the 1-byte code buffer 32 and the 2-byte code buffer 33 are edited and displayed in the editing buffer 34, a character string 35 appears on the display 302.

This makes it possible to access the character string at the digit position on the display from the buffer at high speed.

〔Effect of the invention〕

As explained above, the present invention makes the digit position on the display the same as the digit position on the buffer in an interactive text editor, so that the character on the display This has the effect of increasing the speed of accessing columns.
