Abstract

PURPOSE:To easily remove an error in input commands without re-inputting the input commands newly when the format of the input commands is wrong by indicating the wrong portion with a cursor and correcting the wrong portion on a displaying screen by means of a correcting means. CONSTITUTION:In a computer system commands inputted in a command input process 101 and checked in a command checking processing 102. When the abnormality of a command is decided 103 in the processing 102, a cursor is moved to the wrong portion of the command displayed on a displaying screen in a cursor moving processing 106 in accordance with an error message output 105. In accordance with the cursor indication, the wrong portion of the command is corrected in a command re-inputting processing 107 without re-inputting the input commands newly. Thus an error in input commands can be removed easily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a command input processing method, and particularly to a command input processing method in which a command including parameters is input while referring to a display screen.

[Conventional technology]

Conventionally, this type of command input processing method inputs the command from the input device according to the command format specified by the computer system, executes the process corresponding to the command if the command format is correct, and displays the command if the command format is incorrect. An error message is output to the device, etc., and the command is input again from the beginning.

[Problem that the invention seeks to solve]

In the conventional method described above, if the input command is incorrect, the command must be input from the beginning, which is very cumbersome, and the command format is complicated because the error location of the command cannot be immediately determined. This has the disadvantage that it takes a lot of time to analyze errors.

[Means for solving problems]

The method of the present invention is a command input processing method in which a command including parameters is input by referring to a display screen from an input device of a computer system, and if the format of the input command is incorrect, the erroneous part of the command is The present invention is characterized in that it includes means for pointing out by displaying a cursor, and means for correcting the command error portion on the display screen.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a flow diagram showing one embodiment of the present invention.

In FIG. 1, 101 is a process of waiting for command input and performing command input (hereinafter referred to as command input process);
102 is a process for checking the normality of the input command format and contents depending on the case (hereinafter referred to as command check); 103 is a process for determining the command check result and branching to a normal route or an abnormal route (hereinafter referred to as □) ), 104 is execution of processing corresponding to the input command, 105 is error message output processing when a command check is abnormal, 106 is cursor movement processing to display the error part of the command, and 107 is a command that prints on top of the command. 108 is an escape process that cancels the command re-input and inputs a new command.

FIG. 2 is an example of a screen image on a display device for explaining the operation of this embodiment.

201 is a display screen 202 and 206 is a mark indicating a command input request to the operator; 203 is a command and a command parameter (hereinafter referred to as a command); 204 is a slant for executing the input command; 205
207 indicates an error message that is output when the input command is incorrect, and 207 indicates the error part in the command format.

When a computer system performs some processing, first, in command input processing 101, a command input request mark 202 is displayed to prompt the operator to input a command from an input device. When the operator inputs a command 203 in command input processing and subsequently inputs a slant 204 specifying command execution, command check 1 is executed.
02 processing is performed. Depending on the result of command check 102 in determination 103, the process branches to normal processing or abnormal processing.

If it is normal, execute the command for the corresponding process 10
Perform step 4 and finish.

If it is abnormal, an error message 205 is displayed on the display screen 201 by the error message output 105. Since the command check 102 has revealed the erroneous part of the command, the cursor is moved to the erroneous part 207 of the command by cursor movement 106. Next, command re-input processing 107 is performed. In command re-input processing 107, the error portion 207 where the cursor is located is corrected and the command is executed again.

When the user wishes to cancel this command re-input process 107 and input a new command, a new command input request mark 206 is displayed by escape 108, and the processes subsequent to command input process 101 are executed. Further, when the command re-input processing 107 is desired to be utilized, the processing after the command check 102 is performed.

〔Effect of the invention〕

As explained above, according to the present invention, if an input command is incorrect, the erroneous part of the command can be immediately identified by the cursor position. Since there is no need to re-enter the command, even if the command format is long or complex, it has the effect of eliminating the trouble associated with eliminating input errors.
