Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to control of command input in an electronic computer system, and more particularly to a control method that takes into account facilitation of command input.

(Background of bJ technology In a computer system, an operator issues commands by operating keys on the system's console, operator console, or interface called a terminal device (hereinafter collectively referred to as the terminal device). A commonly used method is to input a command, the computer system executes the processing specified by the command, and displays the result on a display device of a terminal device or the like.

In such a system, in addition to preparing appropriate commands and displaying appropriate displays, it is important to ensure that command input is easy and that erroneous specifications are unlikely to occur. This is an important matter for improving.

(C) Prior Art and Problems In the above-mentioned system, the operator often repeatedly inputs the same or only partially different commands during a certain task.

For example, in a system that controls the execution and debugging of a program, if you want to see the value of a variable in the program at every break in program execution, for example, the command "rllRITE A" that specifies the display of variable A will be used many times. If we also look at the value of variable X at the same time, we will see a command that differs only in the variable name from the above, such as "1ITE

In such cases, it would be convenient to be able to use a command once entered repeatedly with a simple operation. In addition, it is thought that input errors will be reduced if the number of input key operations is reduced, but no suitable method has been provided in the past.

Conventionally, as a method to reduce the number of command keys,
There is also a method of registering a command or a string of multiple commands and calling it manually using a key with a relatively short registered name, but since it is necessary to register it in the system in advance, the requirements in the above cases is not adequately satisfied.

(d) Purpose of the Invention Accordingly, the purpose of the present invention is to reuse previously input commands as they are or with partial modifications without the need for registration or other operations and with a simple recall operation. The purpose of this invention is to provide a command input control method that makes it possible.

Tl1) Structure of the Invention The object of the present invention is to provide a computer system having a function of executing commands input by an operator from a terminal device, a means for storing the commands, and a means for storing the commands; This is achieved by the command input control method of the present invention, which comprises means for displaying a command stored in the command storage means on the terminal device, and means for processing the displayed command or a command obtained by modifying the displayed command as an input command. Ru.

That is, when a command input by an operator is executed, a function is provided to automatically store the command in the computer system, and the stored command is displayed on the terminal device by simple manual key designation. Since the original or modified version is processed as a command similar to the command entered manually, the operator does not need to be particularly conscious of registration, etc., and can reuse previously entered commands. .

(f) Embodiment of the invention FIG. 1 is a block diagram of a system according to an embodiment of the invention. The main body of the computer system consists of a normal central processing bag W1 and a main storage device 2, to which a terminal device 3 such as a keyboard/display device for inputting and displaying commands by an operator is connected via a control device 4. be done. Hereinafter, the present invention will be described in detail regarding the case where program execution and debugging are performed in the system shown in FIG.

2 is loaded into the main memory 2 and the central processing unit 1
FIG. 2 is a diagram conceptually explaining a program, control information, etc. executed by the computer. When performing the above-mentioned execution debugging, as is well known, for example, a program 10 of a debugging system is loaded into the main storage device 2 and executed, and a program to be debugged 11 is executed under the control of the program.

As is well known, the debug system 10 holds debug control information 12 input from the terminal device 3 prior to execution of the program to be debugged 11, and executes the program to be debugged while monitoring it. When execution advances to the address of the debugged program specified in 12,
This is a program that has a function to perform controls such as stopping the execution and displaying the stop address etc. on the terminal device 3.

For example, in such a state where the execution of the program to be debugged is stopped, the debug system 10 performs control according to commands input from the terminal bag W3. Commands input in this case include displaying the value of a variable in the program to be debugged (the WRITE command in the example above), assigning a value to a variable, starting execution from a specified address, and others.

Input from the keyboard of the terminal bag W3 is held by the control device 4, and characters, numbers, symbols, etc. are displayed on the display device. They can be modified on the display surface by the operator's keystrokes.

When a specific key (hereinafter referred to as the F1 key) is pressed manually on the terminal bag W3, the control device 4 stores the input information held in the main storage device 2.
The debug system 10 receives this and executes it if it is a command.

At this time, the debug system 10 transfers the command from the input buffer 13 to the command stack 14 and stores it. For example, the command stack 14 stores one command in one term, and is a continuous storage area composed of an appropriate number of terms. When a new command is input, the final product pointer 15 is updated to the next term, and the corresponding term is Store commands in terms.

In this way, when commands are stored in all the entries in the command stack 14, commands input afterward are stored again from the first entry, and previously stored commands are sequentially erased. Therefore, the command stack 14
Only the most recent input commands up to the number of terms are kept on the stack.

When the operator wants to use a previously entered command,
Input a specific key (hereinafter referred to as the F2 key). When the debug system 10 detects the input of the F2 key, it places the contents of the final product pointer 15 in the display pointer 16, and copies the command of the item pointed to by the display pointer 16 on the command stack 14 to the output sofa 17. The control device W4 reads out the output buffer 17, holds it, and displays it on the display of the terminal device 3.

When the F2 key is input again, the debug system 10 updates the contents of the display pointer 16 to point to the previous item, and transfers the command held in the item pointed to by the display pointer 16 to the terminal device 3 in the same manner as before. In this way, each time the C2 key is input in succession, the input commands - times before are sequentially switched and displayed.

The control device W4 controls the commands received from the buffer 17 and displayed in the same manner as if they were input from the keyboard of the terminal device 3. That is, the operator can modify the displayed commands by manually pressing the keys as described above. Further, when the C1 key is input, the control device 4 passes the displayed command to the debug system 10 via the input/output buffer 13 of the main storage device 2.

Debug system 10 processes and executes this command in the same manner as normal input, and also advances final product pointer 15 and stores the command in the final product of command stack I4.

In the above explanation, depending on the F2 key's strength, the previous commands are displayed sequentially starting from the most recently input command, but it is also possible to switch the displayed commands from the oldest command to the most recent command, or Even if an item of the command stack 14 can be specified by a combination of a key and, for example, a numeric key, this does not detract from the gist of the present invention.

Furthermore, in the above explanation, it is assumed that the command stack I4 and the related pointers 15 and 16 are located in the main memory W2 and are controlled by the debug system 10, but the command stack 14 and its control functions are controlled by the control device. It may be provided in W4. Any of these changes can be easily implemented by analogy with those skilled in the art from the above description.

(Effects of the Kozue Invention As is clear from the above explanation, the present invention provides a function that automatically saves input commands and allows them to be reused. This speeds up command input operations and prevents input errors. This has a significant industrial effect of reducing the amount of electricity and increasing the utilization efficiency of the computer system.
