Description

[Detailed description of the invention] <Industrial application field> The present invention relates to word processors.

<Conventional technology and its problems> In word processors, etc., the key codes of a series of keys pressed by the user are stored as they are in RAM, etc., and when the user wants to perform the same operation, the key code string (hereinafter referred to as procedure) is used. The method of calling and executing is already in practical use.
However, in the conventional system, only the same operations can be executed again, so it is not possible to make a decision midway through a procedure and change the operation based on the result of this decision.

<Object of the Invention> The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a word processor that can add a judgment function to a procedure.

<Means for Solving the Problems> The word processor of the present invention is a device for inputting and editing characters based on the cursor position, and includes a keyboard, a text memory for storing input character strings, and the keyboard. a character input editing section that stores character codes input from the text memory and edits character strings in the text memory based on editing instructions from the keyboard; a key buffer that stores key codes; and a key buffer that stores input from the keyboard into the key buffer. a registration control means for storing in the key buffer a key code corresponding to a series of key operations for inputting and editing, and storing a judgment code input from the keyboard, a comparison condition, and predetermined processing information; sequentially reads out the key codes and supplies them to the character input editing section, and in response to detecting the code content of the judgment code, determines whether or not the character at which the cursor of the text memory is located corresponds to the comparison condition; The present invention is characterized in that it includes a reading control means that executes processing according to the processing information when the conditions are met and supplies a subsequent key code to the character input editing section.

<Embodiment> FIG. 1 shows the basic configuration of a word processor of this embodiment. Reference numeral 1 denotes a keyboard, which includes a judgment instruction key, a re-execution key, a character input key, and a command key. 2 is a CPU, and 3 is a display device such as a CRT. A key storage buffer 4 stores key codes corresponding to key inputs on the keyboard 1. 5 is a text buffer that stores input character strings. A pointer 6 designates a character corresponding to the cursor on the screen of the text buffer 5, and also designates a key code of the key storage buffer 4.

FIG. 2 shows the structure of the keyboard 1. 11 is a command key for instructing cursor movement, backward movement, etc., 12
13 is a character input key for inputting characters, and 13 is a judgment instruction key for instructing to make a judgment in a processing procedure. 14 is a re-execute key, and when this re-execute key 14 is pressed, the process corresponding to the series of key codes stored in the key storage buffer 4 is executed. 15
is a start/end key, which instructs the key storage buffer 4 to start and end storing the key code.

The operation will be explained below.

Characters input from the keyboard 1 are stored in a text buffer 5. Processing corresponding to the command input by the command key 11 is executed by the CPU 2. For example, when moving the cursor, the pointer 6 is changed. When you press the start/end key 15,
Key codes for subsequent key inputs are stored in the key storage buffer 4. When the start/end key 15 is pressed again, storage of the key code into the key storage buffer 4 is stopped. When the rerun key 14 is pressed, the key code string stored in the key memory buffer 4 is
The CPU 2 reads the key code string, and the CPU 2 executes processing corresponding to this key code string.

When keys are inputted sequentially from the keyboard 1, a step number is displayed on the screen of the display device 3 at the same time as the key code is stored in the key storage buffer 4, as shown in FIG. 3, for example. Then, when the judgment instruction key 13 is pressed at a step that requires judgment,
A window for inputting judgment content as shown in FIG. 4 is displayed on the screen, and in accordance with this window, a comparator such as "greater than or equal to" or "less than", and comparison content of letters and numbers are input. This content is not stored in the text buffer 5, but is stored in the key storage buffer 4 as a suitable internal code. It is also possible to input only the judgment instruction key 13 during key input, display the content of the procedure on the screen, and input the comparator and comparison content when modifying the procedure.

When the start/end key 15 is pressed, the pointer 6 is set to the first step of the key storage buffer 4, and the pointer 6 is raised each time a key code for a subsequent key input is stored in the key storage buffer 4. In the case of a determination key, it is changed to the storage code inside the key storage buffer 4, stored at once, and the pointer 6 is raised. When the start/end key 15 is pressed again, the end code is stored.

When the rerun key 14 is pressed, the pointer 6 is
The key code is read from the key storage buffer 4 with the first step. The key codes are sequentially read out, and if it is not a judgment code, the key code is output as is, and the pointer 6 is raised. If it is a judgment code, the content of the key code following it is judged, the pointer 6 is changed according to the result, and the process jumps to the changed step. If it is an end code, output of the key code is stopped at that point.

Here, a procedure for extracting data on only women from an address book as shown in FIG. 5 will be explained. FIG. 6 shows the contents of the key storage buffer 4 in this case.

The key code “0001” in step 4 means judgment of the character at the cursor position, “1100” in steps 5 and 7 is an identification code surrounding the variable-length character strings to be compared, and “2161” in step 8 means “if they are equal, "000C" in step 9 is a code indicating step number 12 to jump to.

In steps 4 to 9, it is determined that ``if the character string at the cursor position is ``woman,'' the process jumps to step 12. If the character string at the cursor position is "male", that line is deleted in steps 10 and 11. In other words, the man's data will be deleted.

The key code “0002” in step 12 means to judge whether the cursor position is at the end of the sentence.
13 "0001" is a code indicating the jump destination step number 1. At steps 12 and 13, "If the cursor is not at the end of the sentence, jump to step 1"
This is the judgment. If the judgment result is the end of the sentence, the procedure ends.

With the above processing, only the woman's address book remains on the screen.

<Effects of the Invention> As explained above, according to the word processor of the present invention, the registration control means sequentially stores key operations input thereafter based on instructions from the operator, and performs the same key operation again. In this case, the previously stored key operation is read out and the predetermined key operation is performed based on the judgment code comparison, so in the process of performing a series of key operations, for any series of key operations, It is possible to re-execute the process without performing any key operations. Furthermore, if a partially different key operation is performed under conditions such as a predetermined position or a predetermined character, this fact can be registered, and when the predetermined position or predetermined character conditions are met at the next readout, the specified content key operations can be performed. These functions are particularly effective when editing a document that has been created once. In addition, it is possible to output a key code according to the judgment in this way, and procedures with a wide range of applications can be performed, improving functionality.
