Abstract

PURPOSE:To improve the operability of a command input system by writing the contents of a command history buffer in to an external storage when the command executing frequency is coincident with the command execution prescribing frequency. CONSTITUTION:The executed commands are written into a command history buffer 12 and then it is checked whether the command executing frequency is equal to the prescribed command execution prescribing frequency or not. When the coincidence is secured between both frequencies, a command history file of the buffer 12 is written into an external storage. Then a command is sent to a command analyzing means 31. The command analyzed by the means 31 is processed by a command processing means 30. Thus the commands can be selected and inputted as long as these commands are used once in the past even if a command is partly forgotten or a long or complicated command is frequently used.

[Problem to be Solved by the Invention] However, in the conventional command input method of a computer system, when a long command or a part of a complicated command is forgotten, it is necessary to consult Manual-C. Another problem is that even if long or complex commands are used many times, they must be entered from the keyboard each time.

The invention is equipped with a simple command input device that allows you to select and enter commands if you forget part of a command or use a long or complicated command many times if you have used the command in the past. The purpose is to provide a command input method for computer systems.

[Means for Solving the Problems] In order to achieve the above object, the command input method of the computer system of the present invention includes a command history buffer for storing executed commands as a command history file, and a system in a simple command input state. After displaying the command history file, selecting and executing the command, the executed command is written into the command history buffer, and the number of command executions is compared with the specified number of command executions, and when they are equal, the command history is displayed. It is equipped with a command call processing means for extracting the contents of the buffer to an external storage device.

[Operation] In the command input method of the computer system configured as described above, first, the mode switching means changes the system to a simple command input state. Next, use the input means to call up the command history file from the command history buffer.

Display on display means. Furthermore, a command is selected and executed using an input means. The executed command is first written to the command history buffer, and then checked whether the number of command executions at that time is equal to a predetermined number of command executions. When the number of command executions is equal to the specified number of command executions, the command history file in the command history buffer is written to the external storage device.

After the writing is completed, the command is passed to the command analysis means, analyzed, and then processed by the command processing tool Q.

Therefore, even if you forget part of a command, or if you use a long or complex command several times, if you have used that command in the past, you can select and input it.

[Example] An example of the present invention will be described with reference to the drawings. In addition, key points common to product drawings are given the same reference numerals.

The command history buffer F 712 (hereinafter translated as command buffer I2) stores executed commands in the command history buffer.
This is a buffer to record and store as files. f; RT4
．． The keyboard 5 serves as a display and input means in the same way as described in the prior art section, and the external writing/typing device 6 records executed commands as a command history file. The command call processing means 21 is connected to the reading means 22 and the output 1<
Means 23. Execution number changing means 24,
Exporting means 26. Command temporary holding means 27, fortune telling means 28. Command execution specified number of times memory 1u 29
, command processing means 30, and command analysis f-[Ω3I. Among these, the command processing means 30 and command analysis means 31 are the same as those described in the prior art. The read f-stage 22 receives the command call 1. output from the keyboard 5. - When you input No. 4, command buffer I
The command history file is read from 2 and displayed on the CRT 4. When the selection means 23 receives the selection signal output from the keyboard 5, it selects a command from the command buffer 12 and inputs it to the command temporary holding means 27. The execution number changing means 24 inputs an execution signal from the keyboard 5 and counts the number of command executions, and outputs an output signal to the command temporary holding means 27 to cause the command analysis means 31 to output the held command. Further, an output signal is also output to the intrusion means 28 to cause the command held in the command temporary holding means 27 to be written into the command buffer 12. Further, the counted number of command executions is output to the comparing means 25. Comparison 1925 compares the number of command executions output from the execution number changing means 24 with the prescribed number of command executions stored in the prescribed number of command execution times storage means 29, and outputs an output signal to the writing means 26 when the number of commands is too low. The contents of the command buffer 12 are output to the external storage device 6.

FIG. 2 is a schematic block diagram showing an embodiment of a computer system having a command input method according to the present invention.
The main body 1 is composed of a CPU 2 and a memory 3. The memory 3 includes an 0/S engineering area 8 that stores 0/S, and a command analysis program area 9 that stores a command analysis program.
, working area for storing text, data, etc.
O. A command buffer 12 for storing a command history file is provided. Each one stage constituting the mode switching means 20 and the command call processing means 21 is achieved by O/S, command analysis program working area 10, and CI U2 stored in the memory II.

FIG. 3 is a schematic diagram of the command buffer at initial setting. The number 0 is the number of the stored command, indicating that 200 commands can be stored. Also, the higher the number, the more recently written the command. Twenty commands are read out by the reading means 22 and displayed on the RT4.

Next, the operation will be explained according to FIG. FIG. 4 is a flowchart showing the command input method of the present invention. First, in step S, the system shown in FIG. 2 is initialized. During the initialization process, the command history file used when using the 0/S, command analysis program, and pre-concave system is loaded into the memory 11 of the main body 1 from the external device 6. In step S2, the state becomes ready for input, and a prompt is displayed on the screen of CR1'4. When a user wishes to use a simple command input device for inputting commands, a mode switching key (not shown) on the keyboard 5 is pressed. By pressing the moto switch key, the 0/S switches the system to the simple command input IR mode shown in FIG. 1. In step S4, the command call key (not shown) on the keyboard 5 is pressed. The command call signal is input to the read stage 22, and the 20 commands from the command buffer γ12 shown in FIG. 3 are displayed on the CBr4 for the first time. If the desired command is not found there, press the scroll key (not shown) on the keyboard 5. Then, the 20 example commands displayed for the second time are displayed on the CBr4. If it is not there, press the scroll key again. Assume that the target command is the 20th command for the second display, that is, the 40th command in the command history file stored in the command buffer 12. Step S.

Press the cursor key on keyboard 5 to move the cursor. When the position of the cursor is changed, the number 18 is inputted to the transfer means as a selection signal, and the command at the position of the cursor is stored from the command buffer 12 into the command temporary holding means 27. Therefore, when the cursor is moved to the beginning of the 20th command of the second display, the 40th command of the command history file is stored in the command temporary holding means 27. When the command selection is completed, the process advances to step S6 and an execution key (not shown) is pressed. When the execution key is pressed, an execution signal is input to the execution number changing means 24, and the number of command executions is increased by +1 each time the command is executed. In reality, the registers and arithmetic unit of the CPU 2 and the working area 10 of the memory 11 are used, and the constant corresponding to +1 and the previous command execution time are moved from the working area 10 to two registers, and the arithmetic unit The execution number changing unit 24 adds the result to the area storing the actual number of commands 11 and the previous command f:r, and holds the calculation result in one of the registers. The number of times is incremented by 1, and an output signal is output to the command temporary holding means 27 and the writing means 28. In step S7, the writing means 28 moves the 39th command in the command history file to the 40th command, and similarly moves the 39th command to the 40th command.
The commands are sequentially shifted, such as the 39th command, and finally the command stored in the command temporary storage means 27 is moved to the 1st command. In step S8, the command is recorded in the execution number changing means 24. The number of executions of a certain command is output to the comparing means 25. The comparing means 25 compares the prescribed number of command executions stored in the command execution prescribed number of times recording means 29 and the number of command executions. If the comparison results are the same, the writing means sets a writing signal level of 1". 26. In step S, the writing f stage 26 outputs the command history file stored in the command buffer 12 to the external storage device 6. After outputting the command decoy history file to the external storage device 6, S
Proceeding to IQ, the command stored in the command temporary holding means 27 is output to the command analysis means 31. The following commands are from command analysis 10jU31 to command processing means 3.
Passed to 0 and processed. When the command processing by the command processing means 30 is completed, the simple command 1: Input ready status is changed to 7.
L: Returns to normal command input state. As a result of the comparison in step S8, if the number of command executions is smaller than the specified number of command executions, a write signal level "0" is output to the write means 26. The writing means 26 does not output the command history file to the external storage device 6 when the writing signal is at level °°0''. If it is not used, that is, in the case of normal command input in which commands are assembled and input by pressing keys one by one from the keyboard 5 as in the prior art, the mode 1.0 conversion key is not pressed in step S3, and steps S, S3, and S6 are performed.
, sho are repeated to assemble the command, and then steps S6, Sl, S8, S9, and Sin are performed.

[Effects of the Invention] Since the present invention is configured as described above, it achieves the effects described below. 6. A command history buffer for storing executed commands as a command history file and a simplified system. Switch to a state where command input is possible. After the first step of mode switching, displaying the command history file, selecting and executing the command, write the executed command to the command history buffer, and then compare the number of executions with the specified number of times and when they are equal. Equipped with a simple command input device consisting of a command call processing means that writes a command history file to an external storage device, it is easy to use even if you forget part of a command, or if you use a long or complex command many times. However, if you have used that command in the past, you can select it and enter it.
This saves you the trouble of stopping work to manually look up forgotten commands, or of repeatedly entering long or miscellaneous commands.

In addition, the contents of the command history buffer are periodically written to an external storage device, so even if the command history file in memory is destroyed due to a power outage, it can be written to the external storage device before it is destroyed by initializing the system. The saved data can be used again as a command history file.
