JPS62100861A - Control system for character input position in character editing process - Google Patents

Abstract

PURPOSE:To obtain quickly a character input enable position by retrieving a retrieving direction storing table which is decided by the type of the control code and the retrieving direction of the character input position and performing an editing job. CONSTITUTION:The character data supplied from an input device 11 is transferred to an editing job processing means 12. The means 12 transfers all input character data on the line having an input request to an input position control means 13 together with the information on the digit position to be supplied next in case no designation is particularly given. The means 13 checks whether or not a control code exists at the corresponding digit position. If the control code exists, a retrieving direction table 14 is retrieved from said control code and the retrieving direction of the present character to obtain the retrieving direction of the next character. At the same time, the propriety for input of character data is checked and this checking result is delivered to an editing job processing means 12. As a result, the means 12 edits the input character data and displays the character data supplied to a screen display device 15 at an appropriate position.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is used in an information processing system and relates to controlling the position of character input in character editing processing.

``Prior art'' Conventionally, character input position control in character editing processing has been performed by representing the current character input position with only one row and column 7.
A method was used in which the information was updated according to the input of characters.

"Problems to be Solved by the Invention" In the conventional character input position control method described above, the input position is represented by only one digit in a row, so a control code exists in the process that involves editing one character, and the control code contains If character input is not allowed, or if the input position of the character needs to be corrected to a specific position rather than the next line or column depending on the type of control code, the character that has already been entered can be It is necessary to search for possible input positions by sequentially determining each character from the line and column position, which has the disadvantage that the search process is time consuming and complicated.

"Means for Solving the Problems" The character input position control method in the character editing process of the present invention is based on two elements: the character search direction and the type of control code to search for the next character input position. Prepare a search direction table that stores information indicating the next search direction, and when a character is input, all character data control codes in the line containing the last input character are input, and if there is no specification, the next Determine whether or not there is a control code at that position from the digit position information to be input, and if there is a control code, refer to the above search direction table using that control code and the character search direction up to that point, and calculate the result. The search direction is determined by

"Example" FIG. 1 is a block diagram showing the entire embodiment of the present invention.

Character data input by the input device 11 is first passed to the editing work processing means 12. The editing work processing means 12 inputs all character data that has been input in the line requested by the input position control means 13 and the digit position to be input next (in this example, the digit position of the previous input) unless otherwise specified. digit to the right)
Pass the information. The input position control means 13 determines whether or not there is a control code at the relevant digit position, and if it is a control code, the search direction table 14 is determined based on this and the current character search direction.
is searched, the search direction of the next character is determined, and whether input is possible or not is determined, and the result is passed to the editing work processing means 12. Based on the results, the editing work processor 1iQ12 edits the input character data and displays the input character data on the screen display device 15 at an appropriate position. The above is the overall flow of operation.

Next, the structure of the table 14, the procedure for searching it to obtain the search direction for the next character input position, and determining whether input is possible will be explained using a specific example.

Here, as a control code, we will take up a control code that generates a frame 21 on the display screen as shown in FIG. 2A.
A control procedure for inputting characters 22 as shown in FIG. 2B will be described below.

In table 14, "["-"1"]""L"" is taken as a vertical element as a control code to generate a frame, as shown in FIG. 3, and the horizontal element is used to search for a character input position. The directions are "Top", "Bottom", "Right", and "Left".The next search direction is arranged in the table 14 corresponding to each vertical and horizontal element.For example, if the vertical element is "" and the current If the search direction for is “left”, then the next search direction for it (=
``Bottom''.

The current state is shown in Figure 4A, and the last input character data is the rightmost character of the first line in frame 21.
Suppose that character data of "F" is then manually entered from the input device 11.

At the time when the input of the previous character data 'E n is completed, the search direction for the next character input position is "right". The editing work processing means 12 passes the character data input so far in the line containing the character "E" and the digit position to be input next to the input position control means 13. The input position control means 13 determines whether or not there is a control code at that digit position,
In this example, since there is a control code 1'' and the search direction is ``right'', the search direction table 14 is searched and ``down'' is obtained as the next search direction.

This search direction "down" and the information that cannot be entered because the digit position is a control code are processed by the editing work processing means 1.
Return to 2. The editing work processing means 12 passes all the character data and control codes of the line one line below from the search direction "bottom" to the input position control means 13 again. In the input position control means 13, there is a control code "1n" in the digit position in this row as well, and the search direction is "down", so from these, the search direction table 14 determines the search direction "left" and the information that input is not possible. is returned to the editing control processing means 12. Since the editing work processing means 12 cannot input the digit, it shifts the digit position by one character to the left and passes control to the input position control means 13 again.The input position control means 13 inputs the passed digit. If there is no control code at the position, the search direction is left as is and information indicating that input is allowed is returned.

In addition, in the editing work processing means 12, when the search direction becomes 6 right and input is possible, a character is input in that digit position, but until then, the search direction remains 6 left, and the editing work processing means 12 is input. The control reciprocates with the position control means 13, and when the leftmost control code "1" is found, the search direction becomes "right", and then the search result for "right" can be input, and the search direction is "right". The editing work processing means 12 obtains the information "" from the input position control means 13, inputs "F" into that digit position, and displays the data on the screen display device 15 as shown in FIG. 4B. In this way, the character data “F” is converted to “El”.
It is not entered next to (to the right of) ``, but to the right of 1'' on the next line.

In this way, in this invention, information indicating the position of the first A' of the characters to be inputted one after another is inputted by setting the cursor, but after that, simply inputting the characters to be inputted one after another results in the control code position ( It automatically determines that it is 2, changes the line, and also automatically determines the first input position, and displays the input character there.

"Effects of the Invention" As explained above, according to this invention, the input position can be
A table storing search directions determined from the type of control code and the search direction of character positions is used, and editing work is performed by searching this table, so input possible positions can be quickly determined. By selecting the vertical and horizontal elements of this search table, it is possible to apply it to complex editing processing.
