Abstract

PURPOSE:To freely write a registering command to an operational program by a simple key operation by providing a program discriminating means to judge whether each row of the operational program stored in a memory part consists of a function or a numeric value and the function. CONSTITUTION:It is judged by the program discriminating means of a CPU 1 whether each row of an operational program which is inputted from a key input part 2 and is stored in a memory part 5 consists of a numeric value and a function or not. Then, when it is discriminated to be affirmative, the practicing of the row is stopped till the numeric value or a stop-ending is inputted, and on the other hand, when it is discriminated to be negative, the practicing of the row is continued and a numeric value input command is described by an optional numeric value and the function. Thus, the input key for the exclusive use of registering is not needed, a numeric inputting command can be written in the operational program freely by a small number of inputting keys and a simple key operation, and the operation can be practiced smoothly with registering arbitrarily by the operational program.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for inputting numerical values into a programmable desktop electronic computer which is used not only to calculate numerical values and functions but also to reserve television programs.

<Prior art> In general, a desk computer with a program is L (Lear).
In n) mode, an arithmetic program written in a simple language consisting of numerical values and functions input from the key input unit is stored in the storage unit, and in A (Auto) mode, the arithmetic program is read out, and the arithmetic processing unit executes the arithmetic program according to the arithmetic program. It automatically performs calculations and outputs the calculation results to a display section or a printing section.

Conventionally, numerical input commands can be written into the arithmetic program written in a simple language by pressing a dedicated numeric key provided as one of the function keys in the key input section in L mode. This is done by writing the corresponding code into the program, but when the above arbiter instruction appears in the program line read in A mode when the program is executed, the program waits until a numerical value is input. Execution has stopped.

<Problems to be Solved by the Invention> However, the above-mentioned conventional desktop electronic calculator requires a dedicated numeric key in the key input section in order to write a numeric instruction in the arithmetic program, and its operation is time-consuming. up,
This has the disadvantage that the increased number of keys makes key operations more complicated. Furthermore, in small models that are limited in the number of keys, the provision of a numeric key makes it impossible to mount another function key, resulting in a deterioration in the functionality of the computer.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it possible to freely write numeric (numerical input) commands into an arithmetic program with simple key operations, without requiring dedicated numeric keys as in the past, and with a small number of input keys. An object of the present invention is to provide a method for inputting numerical values into a desktop electronic computer with a program, which allows smooth calculations using the calculation program.

Means for Solving the Problems In order to achieve the above object, the numerical input method of the present invention provides a numerical input method of the present invention, in which a desk computer with a program has a key input section, a storage section, and an arithmetic processing section. is,
A program determining means is provided for determining whether each line of the arithmetic program stored in the storage unit consists of only a function or a numerical value and a function, and the program determining means determines that the program line consists of a numerical value and a function. When this happens, the execution of that line is stopped until a numerical value is entered from the key input section or the stop/end input is received, but when it is determined that the program line consists only of functions, execution of that line is continued. It is characterized by

First, when writing an arithmetic program, the operator uses the numeric keys and function keys of the key input section to write a program line consisting of arbitrary numbers and functions in the case of a numeric input command, or to write a program line consisting of arbitrary numbers and functions in the case of a numeric input command. writes program lines consisting only of functions to the memory unit one after another. In this case, numerical input commands are written using arbitrary numerical codes and function codes instead of codes using conventional numeric keys.

Next, when reading out the arithmetic program and executing the arithmetic operation, the program determining means determines whether each line of the read out arithmetic program consists of a numerical value and a function. If a numerical value is manually entered from the key input section or a stop end input is input after stopping the operation, the calculation will be restarted using that value or the value written in advance in the program, while if it is determined that it is not possible, the execution of that line will be restarted. continue. In this way, each time the calculation moves to a program line consisting of numerical values and functions, execution is stopped once, and after confirming or replacing numbers, execution is resumed to ensure smooth processing.

<Implementation 1> Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments.

FIG. 1 is a schematic block diagram showing an embodiment of a desktop electronic computer with a program according to the present invention, where l is a CPU as a calculation processing unit that controls the entire computer according to a program and performs calculations, and 2 is a calculation and calculation program. 3 is a CRT for displaying the data and calculation results entered from the keyboard 2 on the screen; 4 is a printer for printing the data and calculation results on recording paper; 5 is a printer for printing the data and calculation results on recording paper; A storage unit comprising a program area 5a for storing the calculation program input from the keyboard 2, a calculation-related memory 5b for storing data necessary during calculation by the CPU 1, and a save area 5c for saving data in the calculation-related memory. RAM
, 6 is a ROM that stores fixed control and calculation programs and constants.

The operation of the calculator is written into the program area 5a of the RAM 5 in a simple language consisting of numerical values and functions, and calculations are made using the CPUI according to the mode and the above-mentioned calculation program that has been read out. A mode switch (not shown) is provided for switching to mode A for executing the process. The above CP
U1 is provided with program determining means for determining whether each line of the arithmetic program read from the program area 5a of the RAM 5 consists of numerical values and functions when the operation mode is the A mode. And the CPUI is
When this program determining means determines Yes, the execution of the line is stopped until a numerical value is input by pressing the numeric keys on the keyboard 2 or a stop end input is received by pressing the Enter key, while when the program determining means determines No. , to continue execution of that line.

FIG. 2 shows an example of storing an arithmetic program in the program area 5a of the RAM 5. This calculation program consists of five lines #001 to 005, and each line is
It consists of a numerical value section 7a, a function section 7b, and a flag 7c. The flag 7c becomes 1 when the row consists of numerical values and functions, and becomes 0 when it consists of only functions. The calculation contents of this program are #001
Add the constant 123 three times to ~003 and add #00 to this result.
The constant 3 is multiplied by 4.005.

The numerical input method in the programmable desktop electronic computer having the above configuration will be described below with reference to the flowchart shown in FIG.

First, in writing an arithmetic program (not shown in the flowchart), the operator sets the mode switch of the keyboard 2 to L mode, and sequentially writes each line of the arithmetic program into the program storage area 5a of the RAM 5 using the numeric keys and function keys. . In other words, if the program line is a numeric input instruction, select an arbitrary constant and function (see #001, 005 in Figure 2), and if the program line is not a numeric input instruction, include only the function (#002 in Figure 2).
-004) are written respectively. Then, the flag 7c in each row is automatically set to 1 or 0. in this case,
Numerical input commands are written using existing numeric keys and function keys instead of using dedicated numeric keys as in the past, so there is no need for space for numeric keys, and the number of public function keys can be increased. It also has the advantage of eliminating the need to press numeric keys frequently, improving the functionality and key operability of the calculator.

Next, in executing the calculation program shown in the flowchart, the operator sets the mode switch of the keyboard 2 to A mode. Then, in step Sl, the CPU reads out the arithmetic program stored in the program storage area 5a of the RAM 5 line by line, and in step S2 judges whether the read line is the last line or not. The process proceeds to step S12 to end the program execution, while if it is determined that it is not the last line, step S12 is executed.
Proceed to step 3. In step S3, the program determining means of the CPU 1 determines whether each line of the read arithmetic program consists of a numerical value and a function, that is, whether the flag 7c (see FIG. 2) is 1. The CPU proceeds to the numerical input mode loop of steps 84 to s9, while if the CPU determines no, it proceeds to step SIO and executes the function calculation for that line. In the loop of the numerical input mode, the CPU 1 temporarily stops execution of the line in step S4, and in step S5 determines whether there is any key input from the keyboard 2. If there is, the CPU 1 proceeds to step S6 to press the key. Determine whether numerical input is done manually. If it is determined that the manual input of the keys is a numerical input, the process proceeds to step S7, where the numerical input is replaced with a numerical value given in advance in the program line, and the process returns to the state of waiting for manual input of the keys in step S5, while If it is determined that the manual input is not a numeric input, the process proceeds to step S8, and it is determined whether there was a manual input of the enter key to cancel the execution stoppage. Then, if there is no enter key, step S5
Returns to the state of waiting for key input, and if there is input key input, the process proceeds to step 9 to complete the process of storing the number in that program line, and then proceeds to step SIO to use the input number to store the number in that line. Resume mental calculation. Finally, when the calculation for that line is finished, the next program line to be read is specified in step Sll, and then the process returns to the first step St.

The flow of execution of the above calculation program will be specifically explained with respect to the program shown in FIG. 2 as follows. The calculation content of this program is "123 + At this time, the numerical value r123J given in advance during the program is displayed on the CRT 3 as shown in the upper part of FIG. Here, if the enter key is input without inputting a number, it is judged as affirmative in step S8, and the above-mentioned numerical value r123J is used for the calculation in step SlO.
．． If 5J is entered manually, it is judged as positive in step S6, and the numerical value is replaced in step S7 to set number r4.
．． 5J is displayed on the CRT 3, and then the enter key is pressed, the first line is executed in the form of "r4.5+". next,
The 2nd to 4th lines are read out sequentially as [+, +, XJ, and these lines are determined to be negative in step S3, and immediately the calculations are executed sequentially in step SIO, and the calculation results at this point are As shown in the middle of Figure 4 <rl is not displayed on CRT3
It is 3.5 (4,5x3)J. Finally, the fifth line "3=" is read out, and in the numerical input mode of steps 84 to S9, only the enter key was pressed manually as shown in the bottom row of Figure 4, so the numerical value "3=" given in advance in the program was read out. 3"
is used for the calculation in step SIO, and after the final calculation result r40.5(13,5x3)J is displayed on Cr(T3), the program execution ends in step S12.In this way, the calculation When running a program, each time a program line consisting of a numeric value and a function that represents a numeric input command is read, execution of that line is temporarily stopped, the digits are confirmed or replaced using the numeric keys or the enter key, and then the digits are Since the used calculation is restarted, the program can be executed smoothly as before.

The simple language for writing the calculation program of the present invention is
The functions are not limited to those of the embodiment, but also include r+, X,
= Not limited to J. Furthermore, it goes without saying that the numerical input method of the present invention is applicable not only to desk-top electronic calculators for calculating numerical values and functions, but also to program reservation devices for video tape recorders and menu reservation devices for microwave ovens.

<Effects of the Invention> As is clear from the above description, the numerical input method of the present invention is applicable to a desk computer with a program having a key input section, a storage section, and an arithmetic processing section. The program determining means determines whether each line of the arithmetic program stored in the unit consists of numerical values and functions. The execution of the line is stopped until the line is reached, but when it is determined that it is not, the execution of that line is continued.The numeric input command is written using an arbitrary number and function, so you can use the input key only for numeric values as in the past. It requires a small number of input keys, and with simple key operations, numerical manual commands can be freely written into the calculation program, and the calculation program can be used to perform calculations smoothly while inputting arbitrary numbers. can.
