Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application in Business A] The present invention relates to a document processing device, and particularly to a document processing device that performs logical, calculation, etc. processing on numerical information and character information on a document storage means.

[Prior Art] Conventionally, in document processing devices equipped with this type of logic and calculation functions, the target range for calculation processing is determined by pressing a range key on numerical data in a table surrounded by ruled lines, etc. was specified, and the calculation result was output at the position indicated by the cursor.

[Problem to be Solved by the Invention] Therefore, in order for an operator to perform this type of calculation processing, the operator must specify the range to be processed and display the calculation result by moving the cursor key B before instructing execution of the calculation processing. There is a drawback that it is necessary to perform a complicated operation of specifying the output position.

[Means for Solving the Problems] The present invention is designed to identify numerical data in a table as a processing target based on the connection relationship of ruled lines extending to the right and bottom at the cursor position at the time of instructing execution of calculation processing. It determines the range that will be processed, and proceeds with logic and calculation processing row by row and block column (determined by the block next to the cursor row). By setting the rightmost block within the processing range as the output area for the calculation results, calculation processing can be executed without specifying the range in the above problem, and the complicated operations that were the drawback are eliminated. .

[Embodiment] The present invention will be described in detail below with reference to the drawings. 1st
The figure shows the overall configuration of the document processing device of the present invention. Here, 11 is a keyboard, which has a command start key, a command for instructing execution of calculation processing, and keys for instructing other processing necessary for character processing.

Reference numeral 12 denotes a CPU in the form of a microprocessor, for example, which performs control necessary for character processing according to processing procedures stored in a ROM 13. The ROM 13 is a memory that stores the processing procedures of the present invention performed by the CPU 2 shown in FIGS. 3 to 5.

The RAM 14 is a writable memory, including a document memory 14a1, a cursor register 14b, a leading display register 14C, a parameter register 14C, and a range register 1.
4d, one unit register 14e1 calculation result register 14f
and other memory areas 14g necessary for character processing. The document memory 14a stores character information based on character codes and information regarding the stored character information.

The cursor register 14b stores the cursor position.

The display head register 14c stores the character position of the first digit of the displayed line of the document memory.

Reference numeral 15 denotes a display device, on which, for example, document information of 20 columns x 3 lines and a cursor are displayed.

Reference numeral 16 denotes a path line for transferring address signals, data signals, and control signals necessary for controlling each section.

The operation of the embodiment configured as described above will be explained below.

When this device is powered on, it first proceeds to step S1 in FIG. 3 and initializes. In step S2, CP
U remains in the state of waiting for key input from the keyboard. If any key is input there, the process advances to step S3.
The CPU determines the manually entered key. As a result of the manual key determination, if the manually pressed key is a command start key, the process proceeds to step S4, and if it is another key that requires the characters IAM, the process proceeds to step S6. In step S4, it is determined whether the command has been entered manually. If it is a calculation command, the process proceeds to step S5 and calculation processing is performed. If the command is another command necessary for character processing, the process proceeds to step S6 to perform character processing. Calculation in step S5! In step A, first, in step 85.1, the parameters given during the manual command are set in the parameter register.

The given parameters include instructions for rounding up, rounding down, rounding off, etc. for the calculation result, and instructions for the number of digits for comma settings. If the given parameters are incorrect, an error is determined in step 35.2, and the process proceeds to step 35.9 for error processing. Once the parameters are set in the registers, step 35.
In step 3, the range to be processed is set. here,
By checking the connections of ruled lines extending rightward and downward with the cursor as the center, the range of calculation processing and the output area of the calculation results can be determined. For example, when calculating the vertical and horizontal totals for numerical data in a table, in Figure 2 (a), the dotted line (A) is the target of calculation processing based on the connection of the ruled lines that extend to the right and bottom with the cursor in the center. The range is 1
B) is the output area of the calculation results. In addition, dotted line (C)
Each part shown in is one column, and the following calculation process is executed based on the width of these columns. Similarly, Figure 2 (
In b), the dotted line <A) is the target range and the dotted line (B
) becomes the output area. In addition, in Figure 2 (C),
Since there is no connection relationship between the ruled lines extending to the right, no calculation processing is performed and an error message is displayed on the display. If the connection relationships such as ruled lines are incorrect, proceed to step 3 as an error.
From 5.4, proceed to step 35.9. If the processing target range has been determined correctly, processing in calculation processing is determined in step 85.5. For calculation processing to obtain totals in a table, such as horizontal total, vertical total, and vertical and horizontal total, the total processing is performed in step 55.6, and the results are stored in the result register. For calculations other than the sum, such as an average, the process proceeds to step 55.7, where other calculation processing is performed and the results are stored in the result register. As a result of calculation processing,
If an error occurs, the process proceeds from step 35.8 to step S5.9 to perform error processing. In either case, in step 35.10, the contents of the result register are displayed on the display based on the contents of the range register, whether the calculation process is carried out correctly or if error handling is carried out. In step S5.6, data for one car is first set in one unit register from the document memory in step S5.6.1. At this time, character data that cannot be calculated within the area (for example, in the case of calculation, characters A, A, KU, ;, -, etc.) are not cleared. For example, when calculating the horizontal total, one unit of data is the numerical data in the columns arranged horizontally in the same row in the target range in the table, and corresponds to A in FIG.

In addition, in the case of a vertical total, the numerical data is vertically arranged in the target range with the width of the first column, and corresponds to B in FIG. If an error occurs during data setting, such as when numerical data in a table contains an invalid character string or the sequence of numbers is incorrect, the process is stopped and steps S5.6.2 and S5.6. At 9, the error flag is set.
For those whose data has been set correctly, addition processing is performed based on the data set in step S5.6.3. If an error such as an overflow occurs during the addition process, an error is determined in step S5.6.4 and the process proceeds to step S5.6.9. If the addition process is completed correctly, processing is performed on the calculation result, such as rounding off and setting commas, in step S5.6.5. This processing is performed based on the parameter values set in step 35.1. The processed calculation results are stored and then output to the calculation result output area in step 556.6. This output area is obtained from the connection relationship of the ruled lines in step 35.3, and in the case of horizontal summation, the rightmost block within the processing range,
In the case of vertical total, it is the previous row within the IA filling range. In step S5.6.7, a check is made to see if the addition process has been completed for all units, and if it has been completed, the summation process is immediately ended.

If not, the same process continues from step S5.6.1 for the next unit.

[Other Embodiments] The means for determining a processing target in the present invention can be applied not only to calculation processing but also to data processing such as sorting, class selection, and so on. For example, in the case of Sow 1-, the data in the same block is based on the data in the cursor row, and by targeting the data after the cursor row, processing can be executed without the need to specify any range, as shown in Figure 7. (a) (b)
), reference data (A) (B) from the cursor position
However, the dotted lines (A') and (B'') are obtained as processing target ranges.The same can be said of select and class.

In the above example, we explained the direction to the right and bottom of the ruled line, but
A different direction of the ruled line is also fine.

[Effect] According to the processing flow shown above, the execution of logic and calculation processing can be performed by issuing an execution instruction without specifying any range. As described above, according to the present invention, when instructing the execution of logic or calculation processing, the operator can simply place the cursor on any ruled line extending in the table, and the desired logic or calculation result in the table can be obtained. It became possible to obtain
