Abstract

PURPOSE:To execute a character string in an external file without especially inspecting the character string by storing only the character string whose effect is confirmed by practically executing it by a console control in a data processor. CONSTITUTION:Since a key inputted character string and a response to the character string from the host side are displayed on a CRT (e), the operator can judge a character to be successively key inputted. When the key inputted character string is effective, the operator depresses a function key to be a specific key for storing the inputted character string in an external storage device. A data analyzing part (b) receives a control code indicating the output of the external storage device and outputs the contents of an input data buffer indicated by an old input data buffer pointer c2 to a disk (g), so that only the character string recognized at its effectiveness by practically executing it is stored in the disk (g).

Description

TECHNICAL FIELD The present invention relates to a console control system, and more particularly to a console control system when a data processing device requires fixed input.

Conventionally, in this type of console control system, all input commands are stored as a history file in an external storage device such as a disk device. With this conventional console control method, unnecessary commands and
Since even the commands for which an operation error occurred will be stored in the history file, if the command input device is switched to an external storage device and execution processing is performed, there is a drawback that even the erroneous commands will be executed.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a console control scheme in which only valid command sequences are stored in an external history file.

Structure of the Invention The console control method according to the present invention includes a key input means,
An input data storage means for storing key-input character data and an external storage control means for writing the character data stored in the storage means into the external storage means in response to an external command are provided. The external command is generated by a key input means when the operator determines that the written character data is valid.

Example Hereinafter, the present invention will be explained in detail using the drawings.

The figure is a system block diagram showing an embodiment of the present invention.

Keyboard a is used to enter data, etc., and the data analysis section analyzes the key-input data and stores it in the input data storage section C if it is normal character data, and outputs control if there is control data. It calls the section d and the disk control section f.

The input data storage unit C includes, for example, two input data buffers c3. c4, and new and double input data buffer pointers cl and c2 that indicate which input data buffer is to be accessed.

According to instructions from the data analysis section, the data stored in this input data buffer is transferred to disk g, which is an external storage device, via disk control section f.
The stored data can be similarly transferred to the input data buffer.

The output control section d displays the data in the data storage section on the CRT display e according to instructions from the data analysis section and passes the data to the transmission/reception control section h. The transmission/reception control section has an R8232C interface function and is capable of transmitting and receiving data with host i.

Next, the operation of the present invention will be explained with reference to the drawings. First, when an operator inputs a character using the keyboard a, the character is sent to the data analysis section. Here, in the initial state, the new input data buffer pointer C1 points to the input data buffer C3, and the multiple input data buffer pointer C
Assume that 2 points to input data buffer C4. Therefore, the data analysis section uses the new input data buffer pointer C.
Stores the key-input character in the input data buffer pointed to by 1. At this time, if the key-input character is a line feed character, the end code NULL is further stored in the input data buffer, the contents of the new input data buffer pointer C1 and the contents of the double input data buffer pointer C2 are replaced, and the output is controlled. Transfer control to section d.

The output control unit d outputs the contents of the input data buffer pointed to by the multiple input data buffer pointer C2 to CTRe and passes it to the transmission and reception control unit.The transmission and reception control unit is R3232.
The data received from the output control unit d is transmitted onto C.

Next, the response of the data sent from the host is R3232C
When the signal is sent through the interface, the transmission/reception control unit receives it and outputs it on the CRTe.

Here, since the character string input by key and the response from the host to the character string are displayed on the CRTe, the operator can determine the character to input by key next.

If the string you typed is valid,
The operator presses the function key, which is a special key for storing input character strings on the external storage device, and the data analysis section receives a control code that instructs output to the external storage device, and stores the input string in the multi-input data buffer. The contents of the input data buffer pointed to by pointer C2 are output onto disk g.

By repeating the processing up to this point, only character strings that have been actually executed and recognized as valid will be stored on the desk g.

Next, when the operator desires to execute the character string stored on the disk, the operator presses a function key, which is a special key for switching the character string input device from key a to disk g. Then, the disk control section f reads out the character string one character at a time from the disk g and sends it to the data analysis section. The following processing is the same as when characters are input from 1r-a.

Through the above processing, only character strings that have been actually executed and confirmed to be valid are stored on disk g.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, only character strings that have been actually executed and confirmed to be valid during console control of a data processing device are stored in an external file.
The effect is that strings in external files can be executed without special verification.
