Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of controlling a display device for processing calculation formulas such as tables displayed on a display screen.

In conventional display devices, calculation formula processing is performed, such as performing calculations on each number in the nine tables displayed on the display screen according to a desired calculation formula, and displaying the result.
In some cases, a programmer creates a calculation program in advance, and then the end user uses that program to enter data and execute it. It was not possible to define the necessary calculation formula using the keyboard while referring to the display l1k1 screen.

The end of rounding is that if the calculation formula you need is not defined, you will need to request a programmer to create a program for that calculation. , it was very time consuming.

In addition, in order to define a calculation formula from an input device such as a keyboard, it is possible to specify a desired position in a table and perform operations on numbers at that position. When the shape of the table or the size of the frame within the table changed, it was necessary to redefine the calculation formula.

The object of the present invention has been made in view of the above-mentioned nine conventional problems, and is a display that allows calculation formulas to be directly defined from an input device such as a keyboard, without being affected by the shape of the fitting, the size of the frame, etc. The object of the present invention is to provide a method for controlling a device.

In order to achieve such an object, in the present invention, a frame field is recognized based on data representing the lines that constitute the frame field, and the position indicated on the display m1ii by a cursor or the like is the position of the recognized frame. Determine which field it belongs to, use it as an operand of the calculation, and define a p calculation formula using this operand and an operator input with a keyboard, etc.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of a display control device that implements the method according to the present invention, and FIG. 2 shows the configuration of an example of the keyboard and display device portions of FIG.

The device shown in FIG. 1 includes a keyboard 1. It is composed of a display device 2 consisting of CR and T, a CRT driver 3, a keyboard driver, registers 51 and 52, a central processing unit (CPU) 6, storage devices 71 and 72, a screen display adapter 8, a CG memory 9, and a screen buffer 10. has been done.

In addition, as shown in Fig. 2, the keyboard 1 includes a calculation key (CAL=?->101, a cursor movement key 102,
Operator key 10B, main value key ~104, constant key 10S1
Execution designation key 106, execution key 107, period key 1
08, a comma key 109, a semicone key 110, and a character key 111 are provided. These keys may be any keys as long as they have the functions described below. The display device 2 separately manages the screen buffer 10 shown in FIG. The register 51 in FIG. 1 stores the position of the cursor on the display device 2 in one row. Further, the register 52 stores a key code generated by the keyboard driver 4 when a key is pressed on the keyboard 1. The storage device 71 stores processing programs used in the present invention, and the storage device 72 stores the processing programs shown in FIG.

A data table shown in Figure 5 is stored.

The CG memory 9 generates characters to be displayed on the display device 2. Furthermore, the 1'vji buffer 10 is a memory corresponding to the display device 2, and by storing the address containing the character pattern in the CG memory 9 in the screen buffer 10, the screen display adapter 8 is connected to the display device 2. 2 Display characters on top. First, the CPU 6 controls each component device, controls the processing program, and controls the entire system.

FIG. 1s3 is a flowchart showing the overall processing flow of the present invention. When a key is input on keyboard 1, it is determined whether the mode is calculation formula definition mode or another mode (step 301) *If CAL key 10
If 1 has been input, the process proceeds to step 3.
Processing moves on to.

When the CAL key 101 on the keyboard 1 is pressed in order to shift to the formula definition mode, key codes generated by the keyboard driver 4 are stored in the register 52.

The CPU 6 refers to the key code in the register 52 and first reads the frame recognition program Dalam (FIG. 6, w) in the storage device 71.
Details are shown in Figure &7. ) (step 308);
Frame Zonada program line, total data in storage device 72 (4th
Details are shown in the figure. ), frame data (details shown in FIG. 5) are created and stored in the storage device 72. When the frame recognition program is completed, the CPU 6 runs the calculation formula definition program (details are shown in FIG. 8) (step 3).
04) In the calculation formula definition program, the cursor is set to 0 point in the definition area 202 of the display device 2, and the system is in a state of waiting for input of formula information. First, enter the formula name. Every time one character of the formula name is input, a key code is generated by the keyboard driver 4 and stored in the register 52. The calculation formula definition program determines the key code in the register 52 and stores the characters input before the comma as formula name information in the formula table in the storage device 72 (details are shown in FIG. 11). set. Further, the CPU 6 stores the CG memory address of each character pattern of the formula name in the address of the screen buffer 10 corresponding to the display position, and sends each character pattern to the CG memory 9 by the screen display adapter 8.
The image is taken out and displayed on the display device 2.

Here, the comma key 109 is used as a division symbol. In this example, KEI8AN is input as the formula name, and then comma key 109 is input. Next, as the scope of the expression, the direction of the definition expression, the number of expressions <),
Enter the number of intervals. Here, it is defined whether the calculations are executed continuously in the row direction and the column direction as the repetition directions, or whether calculations are executed every n times. In this example, <character key 凇 that indicates the line direction as the return direction, < 2 as the number of repeats, and 0 as the interval number.
(meaning of continuous execution) is entered. Each piece of information is stored in a table in the storage device 72 each time a comma key is input, similar to the formula name described above.

When the semicolon key 110 is input after the interval number is input, the interval number is set in the formula table in the memory device [72,
The cursor is set to the 0 point at the upper left corner of the display area 201, and the state waits for expression definition.

(9) If the expression is not to be executed multiple times, if the semicolon key 110 is input after inputting the expression name, the second definition wait state will be entered, and there is no need to input the expression multiple iteration information. Each formula information is displayed by the CPU 6 through a screen display adapter S at a display position in the definition area 202 in the same manner as the formula name.

Next, move the cursor, set the cursor within the round frame bounding the calculation operand, and input the calculation key 103.

The cursor position information is stored in the register 51 by CRT driver <7. The input key code corresponding to the nine arithmetic key 10B is generated by the keyboard driver 4 and stored in the Vjimeta 52. The CPU 6 extracts the cursor position information from the register 51 and stores it in the storage device 17.
2, determine which frame the cursor is in, take out the cursor frame data as an operand, and store it in the expression table in the storage device 72 along with the operator in the register 52. do. Also, edit the data name of the round bar data to be taken out, and enter the definition area 202 along with the operator.
Indicates the inner VcN. The display is the same as Nifuyu name, display position tV
By storing the address of the CG memory 9 with each character pattern in the sofa 10 (corresponding IT screen), b
, one is performed via the maw display adapter a. In this example, set the cursor to 0 point, input operator key 1 to L, 9: #-y set cursor to 0 point, and input operator key 1.
+ of 0B is input. The frame data name is edited into a round shape and displayed as RO2eU1 shown in the example of the display device 20 definition area 202C.

Here, Hiro next sets the cursor to 0, inputs the + operator key, and then inputs a constant. To input a constant, first input the constant key 105. When the constant key 10B is input, the corresponding key code d1 is generated by the keyboard driver 4 and stored in the raster 52. CPUG key in register 52;-
Refers to the code and waits for numeric key input. In addition, the character C and parentheses are displayed in the display position of the definition area 202 by following the screen display button 8. At this point, enter the numerical value key 104. When a constant is input, each character I (turn is inserted into position attc). When the IR value input is completed, the operator key 103
Enter. When the operator key is pressed manually, the CPU 6
Set the LL data in the expression table in the storage device 72. Also, closing brackets and operators are displayed. In this example, after inputting the constant key 105 and inputting the numerical value 160, the equal key of the operator key=103 is inputted. Next, in this example, the cursor is set to point [F] and the period key 108 is input. Period? -108
is input, the CPU 6 determines that the frame data including the cursor position is the result storage area, and stores the data in the storage device 7.
Data is set in the formula table in 2, and the system waits for the next calculation formula to be defined or executed. The cursor is again set below the zero point in the definition area 202.

Furthermore, when defining a calculation formula, the procedure after inputting the formula name is repeated.

The procedure for executing the defined calculations and the operation of each component device will be explained.

First, the cursor is set at the name of the calculation formula to be executed, and the execution designation key 106 is input.

The cursor position information is stored in the register 51 by the CRT driver 3, a key code corresponding to the execution designation key 106 is generated by the keyboard driver 4, and
is stored within. The CPU 6 looks at the key code in the register 52 and presses the execution designation key 1018 to
Step 305 in the figure) runs the calculation formula execution program (details are shown in FIG. 9). The calculation formula execution program searches the cursor position in the register 51 to find out which calculation formula in the formula table it corresponds to, and sets 01 in the execution designation area. At the same time, an execution designation mark is displayed in front of the line drawing name in the definition area 202 of the display device. The CPU 6 stores the CG memory address containing the display symbol pattern in the screen buffer 10 corresponding to the display position, takes out the display symbol pattern from the CQ memory 9 through the screen display adapter 8, and displays it. Do the following.

In the execution designation area, set the -'ivc number sequentially from 01 to the round face where the execution designation is made, and execute the calculation formula in the order in which the execution designation was made.Next, the execution key 107 is input. Then, using the calculation formula execution program], calculations are executed using the numerical data contained in each frame data, and the results are displayed neatly in the result storage. Needless to say, this data must be entered before executing the calculation formula.

The fourth @ shows an example of line data that constitutes a frame, that is, a table. In this embodiment, we will consider a case where the line data table is configured as shown in Figure 4. Any method may be used as long as the starting point and end point position information of the line can be obtained. *If data is necessary, a method of searching the screen to create line data is also acceptable. ζHere, line 11R/C (401
) (01 for vertical line C, 00 for horizontal line R), and an identification number ID (402) that indicates whether a - table is formed.
It is composed of starting point 8Y (403), starting point digit 5x (404), ending point EY (405), and ending point digit EX (406). For the identification number ID, set oot for independent lines, 01 for line data that forms one table, and set Hiro FF as the initial value, according to the data classification process shown in Figure 6. are doing.

In this example, we are talking about a rare case where there is only one table on the screen, but even if there are multiple tables on the screen, all you need to do is add the method to return the processing program shown below. , if the table -94 does not exist, all identification numbers IDs are set to 00, and in the frame recognition process, the frame data table shown below (Figure 5) is completely blank. Not set.

Note that the numbers represented by the fourth IQ are hexadecimal numbers.

FIG. 5 shows a frame data table set based on the line data in FIG. 4 and by the frame recognition process shown in FIGS. 6 and 7. Frame data table line row frame number LNO (
501), minimum row MN"B (502), maximality MXR(
S ova ), outer frame number CN0 (504), minimum column MMC (505), and maximum column MXC (606).

Next, the processing in each processing program shown in FIG. 3 will be described in detail.

FIG. 6 shows the geography of an example of a program that sets an identification number ID by referring to the line data shown in FIG. 4 among the frame recognition programs for the third cause.

First, as an initial setting, set the initial value FF to the identification number ID of the line data table in Fig. 4 (step 5 et
), gray, [1114/C in this line data table
is the horizontal line data OO and the identification number ID is the initial value FF.
In terms of li, find the horizontal line (the horizontal line that is also located above the gill) and set it as R(0), which is 70Sm data.If there are multiple horizontal lines with the smallest starting point property of 8Y, among them The smallest horizontal line data of the starting point digit SX (i.e.,
The horizontal line on which the moth is also located to the left on the screen) is set as R (ψ) (step 603).

Next, the identification number ID of the line data table is FF and the line type is R.
/C takes out the vertical line data 01 and checks whether it intersects with the horizontal line data of R(0) and is i (step 604).
. If there is no vertical line data intersecting with &(0>, 00 is set to the identification number ID of the horizontal line data R(0), and the process returns to step 602 (step 60
5). When vertical line data intersects with horizontal line data R(0), among those vertical line data, change the starting point digit SXO largest vertical line data (the stone vertical line placed furthest to the right on the screen) to C(
0) (step 606), and furthermore, among the horizontal line data other than R(0) that intersects C(O), the identification number ID
searches for the horizontal line data to marry with the initial value FF, and among those horizontal line data, the horizontal line data with the largest starting point property of 8Y (
The lowest horizontal line on ilJI is set to R(υ) (step 609). If there is no horizontal line data intersecting vertical line data C(0), horizontal line data R(
0) and the vertical line data C(0) to the identification number ID, and return to the process of step 602 (step 608
).

Next, set the smaller value of the starting point digit SX of the horizontal line data of %R(OJ and R(1) as RX (0), and set the larger value of the ending point digit EX as RXω. (0
) of the vertical line data is set to 8 Y t-CY (0) and the end point E Y t-CY (1) (step 61G
), RX(ω, RX(1), CX(Φ,
Considering that the dead area surrounded by CX (1) constitutes one table, find all the line data that crosses that area, and consider those - data to be the line data that constitutes the table. Set the data code IDVcOI (mochiro/vR(0), R(1), C(0)
(including line f-1), the process to do this is step 61
1 and 612. That is, in the horizontal line data whose identification code ID is the initial value FF, the starting point property SY is CY(0
) and CY (1), and the starting point digit sx is RX
(1)] is small (i.e., the right end of the area that is considered to be the table area in -improvement also has a starting point on the left side), and the end point digit EX is as large as R(0). Find out the call line data (i.e., considering the table area on both sides, indicating that the left side of the dead area also has an end point on the right side), and find out their! Set 01 to the line data identification number ID. In the vertical line data, the starting point digit 8X small line X (0) and RX (1)
In between, ap, and starting point property 8Y; CX(1)l is also small (in other words, it shows that the lower end of the area considered to be the upper and lower surface area of the − plane is also above), and the ending point property is also small. BY is also large by 0X(0)l (that is, the upper edge of the area considered as the table area on the − plane is also below the top edge). Find the Il line data (Step 611), and The identification number ID of the vertical line data is set to 01 (step 612).In this manner, the identification of the line data forming the table is completed.

Next, ivA is the 6th category in the 6th frame certification program in Figure 3.
This book shows six copies of an example of a program that sets the frame data shown in FIG. 5 based on the data forming the table obtained by the □ process in the figure.

First, as initial values, 0FFH is set in the areas BY and CX set in the frame data table of Figure 5 and the storage device (step 701).

As shown in Figure 4, the data tape λ has an identification number ID of 01.
is set, so step 70 extracts the line data.
2), starting point digit 5Xt-CX of vertical line data among them (
i) (l is from 0 to the number of data), and set the starting point property 8Y of the horizontal line data to BY(j) (j is from 0 to the number of data) (step 703).

Next, CX(i)' and RX(j) are sorted (step 704). Sorted data BYCD, CX(i)
If there is equal data among them, delete one of them. In other words, if RY(j)-RY(j+1), then Ry(j+1
), and if CX(i) = CX (51), then C
XH+1) is deleted (step 7o5).

Next, set the row data. Set j+1 (this is a frame number rounded starting from l) as the row frame number LNO (501) of the ji1th data, and set the row frame number LNO (501) to the row frame number LNO (501).
2), set BY(j), and set Y(j+1)-1 as the maximum digit MXR(503). -1 the largest digit and get i
This is because a horizontal line is displayed at the top of one cell of the display device (step 707). This process is R
Until the data of Y U) is exhausted, that is, BY(j
+1) is repeated until it becomes FP (step 706゜7
08).

Next, set the column data. The surrounding frame number CN0 (504) of the 1-i1th data is set to 1+1 (this is also rounded starting from l as the surrounding frame number).

CX (j) as the minimum digit MMC (SO5), maximum digit MX
Set 0X(i+1)-1 as C(511).

As with the frame data described above, the vertical line is displayed at the left end within one cell of the display device, so the maximum digit is -ed out (step 710). (steps 709, 711), thus completing the setting of data in the frame data table.

As a result of performing the processing shown in FIGS. 6 and 7 for the table shown in No. Lo@(2), an example of the column frame data table created is shown in No. 10#A■. In this embodiment, Underframe data and outer frame data are managed separately), instead of setting individual frames as data, each row and 9 columns are held as data, and the row data and column data can be combined when necessary. A method of configuring frame data is used. Therefore,
For example, in the 10th sharp turn, the first row of the outer frame from the 3rd to the 6th row is the 5th to the 7th row, but the rounding of the horizontal line data starting from the 9th digit of the 6th row, Underframe data 01 consisting of 5 lines m* like 10#A■ line frame data
The underframe data 02 consisting of the 6th and 7th lines are managed separately. Of course, how to take the overall frame accurately,
For example, it is possible to divide one frame data by the left shoulder and right coordinates of Y, but any method is fine as long as the frame detector is set. By inputting the CAL key 101 in the 20-chart that eliminates the tin salt procedure of an example of a calculation formula definition program, this Progera stand.

executes the process (step 801).

11 First, enter the name of the calculation formula in the calculation formula O identification and rounding, and if you want to calculate the calculation by the calculation formula you want to define, or move it back in the column direction, 1. After the formula name, enter the information - 1, i.e. the direction of <ba, the number of <backs, and the interval number indicating whether to execute continuously or at regular intervals. and input the semicolon key (step 1102). If the calculation is not to be repeated, input the formula name and then input the semicolon Φ-. When each piece of information is set as a delimiter), a comma key is used and each item is set at the storage position of the expression table shown in Figure 11. When the semicolon key is input, the process moves to expression definition (step 803).

Next, set the cursor within the frame that you want to use as the operand of the expression, and press Operator key 103, Constant key 105, or Period key 1.
08 is input (step 804).

The input key is operator key 103t+, I×S÷.

If = , < , )) (step g07),
The bone frame and outer frame data including the cursor position are extracted from the 5th FjAO frame data table, the frame data is constructed, and it is stored together with the operator in the expression table of Fig. 11, and simultaneously displayed on the screen (step 808).

The input key is constant key 10! If so (step 806)
, the state is waiting for numerical data, the numerical data is input,
When further operators are input, the number-data and arithmetic expression are combined into 1
Figure 1111 Stores in O-type table and displays on screen (
Step 809). If the input key is the key 1011, the frame data number that matches the cursor position is the bone frame in Figure 5.
Configure the outer frame data, and store this frame as a result storage frame in the formula table in Figure 11 along with a period.
jlkliji display is performed (step 810).

When a period is input and the data is set in the formula table shown in Fig. 11, an error check process is performed (step s11) to determine whether there is an error in the calculation formula (Stella 2812), and if there is an error, the error check is performed (step s11). The message is displayed (step 813), and if there is no error, the process ends.

Figure 9 shows the formula definition information t4 stored in the table in Figure 11 according to the processing of the formula definition program in Figure #I8.
In particular, it is a flowchart showing an example of processing of a calculation formula execution program that executes a calculation formula.

To execute a calculation formula, first set the cursor to the formula name position of the round calculation formula to be executed, and input the execution designation key 106 to define the calculation formula tm to be executed (
Steps 901 and 902).

When the execution designation key is input, a number (
The execution designation input order) is set, and an execution designation mark is displayed before the formula name of the calculation formula on the rIk1 screen. Execution determination can be performed for a plurality of calculation formulas (Stella 7'903).

Next, if the key to move to another mode is input (step 913), the switch to another mode O heat release (step 9
14). During input, - is the execution key, and we move on to the process of executing the calculation formula (step 904).

First, from the equation table shown in FIG. 11, the one with the smallest number among the calculation equations for which execution has been specified is extracted (step 905). In the equation, o<b return number information is set (step 906), and I=O is set as the initial value (step 907).

Until the value of ■ becomes larger than the number of repeats (step 9)
0 @ , ), execution processing ff1 (steps 909, 91
0) is returned (steps 908, 911).

The execution process m first searches for numerical data contained within the frame data of the defined calculation formula and performs the calculation (step 90G), and also searches the numerical data area corresponding to the result storage frame within the calculation formula definition information. The result is set in the file and displayed on the display device (step 910).

When the execution of one formula is completed, the next calculation formula specified for execution is executed. If there are no calculation formulas specified for execution (step 912), the process ends.

□Fuji 11 shows the calculation formula definition table. However).

This shows the format of each data set in the calculation formula information for each area expansion and prisoner of 0.0.

As described above, since the calculation formula is defined using frame data, the input device can directly input the calculation formula without being affected by the shape of the table or the size of the frame. It is difficult to define.
