Abstract

PURPOSE:To practice an operation by a corrected program every correcting time to efficiently correct the program without the impression of complicated ness by saving data inside the operational memory of a memory part when a processing mode is set to a program correcting mode. CONSTITUTION:When a processing mode is set to a program correcting mode, data inside an operational memory 5b is saved to a save memory 5c of a mem ory 5 by the save command means of a CPU 1, and on the other hand, it is judged which the input from a key input part 2 is the deleting or moving com mand of a program row or not by the discriminating means of the CPU 1. Then, according to the affirmation or the negation of discrimination, the dele tion, the movement of program data, the restorage of the data inside the save memory 5c to an operational memory 56 or the writing of the program data to an address where a program memory 52 corresponds are practiced. Thus, every modifying time, an operation can be practiced by the corrected program, the correction of the program can be practiced with confirming that the opera tion is correct more efficiently and without complication compared to a usual system.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to the correction of an arithmetic program for a desktop electronic computer that stores an arithmetic program written in a simple language consisting of numerical values and functions, and calculates numerical values and functions. Regarding the method.

<Prior art> In general, this type of desktop electronic computer has I, (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.

The flow of processing in a conventional desk computer is as follows:
For example, it is as shown in FIG. That is, when inputting an arithmetic program, as shown in FIG. 3(a), if it is determined in step Sl that there is a key input, it is determined in step S2 whether it is the end key or not, and if it is not the end key, step S3 is performed. At step S4, a human key is registered in the program, and at step S4, an input key calculation is executed, and the process continues by repeating the calculation at the same time as inputting the program line by line.

In addition, when modifying the input calculation program by deleting, inserting, or correcting it, as shown in FIG. 3(b), step Sl
Specify the line number you want to modify with l, display that program line in step S12, modify the program line using the key input section in step S13, and only modify the program contents. No calculations are performed. Furthermore, when executing an arithmetic program, as shown in FIG. 3(c), the program is read line by line from the storage unit in step S21, and if it is determined that the program is not at the end in step S22, the instruction of the read line is read out in step S23. Execute and repeat only the calculation without making any modifications to the program contents.

<Problems to be solved by the invention> However, with the above-mentioned conventional desktop computer, when making corrections,
Since calculations cannot be performed using the modified program, it is not possible to proceed with modification while checking the suitability of the modified program through calculations. If you try to do this, either switch the processing mode to program execution mode and check the suitability each time you make a correction or after all the corrections are completed, or switch the processing mode to input mode and change the line after the line to be corrected. The only way to check the suitability of the program is to input each line again using the keys.
n) The advantages of the method cannot be utilized and corrections become complicated;
The disadvantage is that it cannot be efficiently corrected.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it possible to perform calculations based on the modified program each time the calculation program of a desktop electronic computer is corrected, and to efficiently perform the calculations without creating a sense of complication by taking advantage of the more-learn method of the desktop computer. It is an object of the present invention to provide a method for modifying an arithmetic program of a desktop electronic computer by which the program can be modified.

Means for Solving the Problems In order to achieve the above object, the arithmetic program modification method of the present invention corrects the arithmetic program input from the key input section.
Store it in the program memory of the storage unit that contains the calculation memory, read it as necessary and perform calculations in the calculation processing unit,
In a desktop electronic computer that displays calculation results, etc. on a display unit, a save memory provided in the storage unit for saving data stored in the calculation memory, and when the processing mode is set to program correction mode, A save command means for saving data in the arithmetic memory to the save memory; a determining means for determining whether the input from the key input section is a command to delete or move a program line; When the determination is made, the program data stored in the program memory is deleted or moved according to the command, and the data in the save memory is re-stored in the calculation memory. comprising a correction means for writing an arithmetic program consisting of numerical values and functions inputted from a key input section to the corresponding address of the program memory, and executing an arithmetic operation using the corrected program while correcting the arithmetic program in a program correction mode; It is characterized by displaying the calculation results.

Function> Now, when the processing mode of the desktop electronic computer is set to the program correction mode, the save command means saves the data in the calculation memory of the storage section to the save memory. Next, when the operator inputs the contents of the program to be modified through the key input section, the determining means determines whether this input is an instruction to delete or move a program line. When the determination means makes a positive determination, the modification means deletes or moves the program data stored in the program memory of the storage unit according to the command, and stores the data in the save memory again in the calculation memory. On the other hand, when the determination means makes a negative determination, an arithmetic program consisting of numerical values and functions input through the key input section is written into the corresponding address of the program memory.

In this way, the corrected program is stored in the program memory of the storage section, and the data necessary for the calculation is stored in the calculation memory, and the calculation processing section uses these to store the first part of the program.
Executes calculations from the row to the current row and displays the calculation results on the display.

<Example> 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 the desktop electronic computer of the present invention, in which 1 is a C as an arithmetic processing unit that controls the entire computer according to a program and performs calculations.
PU, 2 is a keyboard for inputting numerical values and functions necessary for calculations and calculation programs, 3 is a CRT that displays the data input from this keyboard 2 and calculation results on the screen, 4 is for recording the above data and calculation results. A printer that prints on paper; 5 is a program memory 5a, CP that stores arithmetic programs input from the keyboard 2;
A RAM as a storage unit includes an arithmetic memory 5b including an arithmetic register and an arithmetic flag for storing data necessary during UL arithmetic, and a save memory 5c for saving data in the arithmetic memory.

6 is a ROM that stores fixed control and calculation programs and constants.

The above-mentioned keyboard 2 is used to write calculation programs written in a simple language consisting of numerical values and functions into the program memory 5a of the RAM 5 in order to control the operation of the calculator. A mode switch (not shown) is provided for switching between an M mode for execution and an A mode for executing arithmetic operations on the CPUI according to a read out arithmetic program. When the processing mode is M mode, the CPUI has a storage section 5.
A save command means for saving data in the arithmetic memory 5b to the save memory 5a, and a determining means for judging whether an input from the keyboard 2 is a command to delete or move a program line are provided. Further, when the determination means makes a positive determination, the CPU deletes or moves the program data stored in the program memory 5a in accordance with the command, and reloads the data in the save memory 5c to the calculation memory 5b. On the other hand, when the above-mentioned discriminating means discriminates no, an arithmetic program consisting of numerical values and functions input from the keyboard 2 is stored in the program memory 5a.
A correction means is provided for writing to the corresponding address.

A method for modifying an arithmetic program in the desktop electronic computer having the above configuration will be described below with reference to the flowchart shown in FIG.

When the processing mode of the desktop electronic computer is set to the program modification mode, that is, the M mode, the save command means of the CPU 1 saves the data in the calculation memory 5b including the calculation registers and calculation flags of the RAM 5 up to now in step Sl. is saved to the save memory 5a, and the program counter is initialized to 1 in step S2. Next, the CPU 1 waits for a key input from the keyboard 2 to modify the program in step s3, and if there is a key input, it is determined in step s4 whether or not it is an end key, and if it is an end key, step SI7 The program goes to step S5 to perform program input end processing and end the program, but if it is not the end key, the process goes to step S5. In step S5, it is determined whether or not the key input is a number. If the key input is a number, the process proceeds to step S6, where the number is stored in the numeric value memory, and then the process proceeds to step 816. If the key input is not a number, the process proceeds to step S7, where the key input is confirmed. Determine whether it is an arithmetic function. If it is an arithmetic function, step S8. Proceeding to S9, the function is written to the corresponding address of the program memory 5a of the RAM 5, and after the function calculation is executed, the process proceeds to step 816, while if it is not an arithmetic function, the process proceeds to step S1O.

In step SIO, the CPUI determining means determines whether the key input is a command to delete or move a program line, and if the determination is affirmative, the process proceeds to step St1, where the cput modification means is stored in the program memory 5a. Delete, insert, or move program data according to your instructions. Subsequently, the correction means re-stores (loads) the data in the save memory 5c to the calculation memory 5b in step S12.
As a result, the modified program is stored in the program memory 5a of the storage unit 5, and the contents of the calculation registers etc. necessary for the calculation are stored in the calculation memory 5b, so that the CPU
t is the first step of the program using these in step S13.
After executing the calculation from the line to the current line and incrementing the program counter in step S14, the process advances to step S16.

On the other hand, if it is determined in step SIO that it is the determining means of the CPU 1, the process proceeds to step S15 and is deleted.

After executing processes other than insertion and movement, the process advances to step S16. In step S16, the result of the calculation by the correction program is displayed on the CrtT3 and printed out on the printer 4, after which the process returns to step S3 in a state of waiting for key input.

As described above, according to the present invention including the embodiments described above, when modifying a program, the data necessary for the calculation stored in the calculation memory is temporarily saved to the save memory, and the program data stored in the program memory is deleted. After moving and adding data, the above data can be stored again in the calculation memory and calculations can be executed using the corrected program each time the data is modified.The advantage of the learn method is that the program can be created while confirming that the calculations are correct. You can take full advantage of it and modify programs efficiently without any clutter.

It goes without saying that the present invention is not limited to the above embodiments.

<Effects of the Invention> As is clear from the above description, the arithmetic program correction method of the present invention can be applied to a desktop electronic computer having a storage section having an arithmetic memory and a program memory, a key input section, an arithmetic processing section, and a display section. When the processing mode is set to program modification mode, the save command means saves the data in the calculation memory to the save memory of the storage unit, and the discrimination means determines whether the input from the key input unit is a command to delete or move a program line. Let them judge whether it exists or not, and confirm the judgment.

Depending on whether the program is correct or not, the correction means deletes and moves the program data, re-stores the data in the save memory in the calculation memory, or writes the program data to the corresponding address in the program memory. It is possible to execute calculations based on the modified program, and to modify the program much more efficiently and without any complication than in the past, while confirming that the calculations are correct.
