Abstract

PURPOSE:To facilitate the reuse of a data inputted early by storing an input data in an input history storage means sequentially and displaying the list of the input data on a display means. CONSTITUTION:When a specific input comes from a keyboard 2 or a mouse 3 to display the input data as the list, a history display control circuit 10 reads the content of a buffer number register 9a of a history management circuit 9 and the content of the line buffer from the start to the end is indicated sequentially and the input data stored in the history memory 8 is entirely read out and displayed on a CRT 5 in the format of the list. In order to reuse the data inputted early, when the part of the inversion display is moved to a desired position, the keyboard 2 or mouse 3 is operated to apply the input of the end of selection.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an information processing apparatus that can refer to the history of data (including commands) previously input from input means such as a keyboard.

(b) Conventional technology Normally, in an information processing device equipped with a communication means and used as a terminal device, when a key on a keyboard, which is an input means, is pressed, code data corresponding to that key is sent to a host computer. The combiator on the host side that receives the code data sends the code data back to the information processing device on the terminal side, and the key input by the operator is displayed (input echo) on a display means such as a monitor display. In information processing devices such as workstations and personal computers where input means (keyboard) and display means (monitor display) are treated as a single console, code data is taken in from the keyboard and displayed on the display within the system. It is.

In such information processing devices, input means (keyboard)
Enter the string that becomes the command from , and start working on the system (
It is common to have the system perform information processing (processing of information).

By the way, it is possible to memorize previously input command strings in order as a command history and refer to the stored command history to re-enter (reuse) previously input commands. There are things that are.

To reference and select from the history, for example, if you press a specific key on a line where you want to enter a new command, the commands previously entered on that line will be displayed in order according to the key press, and the desired command will be displayed. You can do this by typing the command as it appears (usually by pressing the Enter or Return key), or by typing the command (string) that displays the history, as in the UNIX operating system. This is done by displaying a list of command history with numbers attached to it on the display, and inputting the number attached to the desired command.

(c) Problems to be solved by the invention However, when referring to the history and selecting from the history using the method described above, in the former case, it is not possible to view the history of previously input commands all at once. I can't do it,
You have to trace the desired command one by one, and in the latter case, you have to enter the command (character string) to display the command history and the number attached to the desired command. Operability was poor.

The present invention has been made in view of the above problems, and provides an information processing device that can display a list of input history and quote previously input character strings from the list display with a simple operation. It is.

(D) Means for Solving Section Groups The present invention provides a display means for displaying data, an input means for performing at least key input, and input data of character strings input from the input means by pressing keys. an input history storage means for sequentially storing input data; and a history management means for controlling the position of the input data in the input history storage means;
and history display control means for displaying input data stored in the input history storage means on the display means, wherein the history display control means displays information on the display means in response to a specific input from the input means. The history of input data stored in the input history storage means is displayed as a list, and when one input data is selected on the display means by the input means from the displayed history list of input data, the selected one is displayed. This is an information processing apparatus in which input data is input from the input means.

(E) The input data inputted from the action input means are stored in the input history storage means in order, and a list of input data stored in the input history storage means is displayed on the display means according to a specific input from the input means. Since one input data is selected on this display means, previously input data can be easily reused.

(f) Example FIG. 1 is a schematic diagram of an embodiment of the apparatus of the present invention.

Display data stored in the display memory (6) is displayed on the CRT (5) under the control of the display control circuit (7) according to the control circuit (1).

When the control circuit (1) receives data input from the keyboard (2) (a code corresponding to a key press),
The data is displayed on the CRT (5) by the display control circuit (7).
(However, only data that can be displayed) is displayed as an input echo.

(8) is a history memory as an input history storage means, and data input from the keyboard (2) and sent to the display control circuit (7) as data to be displayed on the CRT (5) is stored in the history management circuit as a history management means. (9) was also sent,
It is stored in the history memory (8) via this history management circuit (9).

(lO) is a history display control for displaying a list of input data stored in the history memory (8) on the CRT (5) in response to a specific input from the keyboard (2) or mouse (3). This is a history display control circuit as a means.

FIG. 2 shows a schematic configuration diagram of the history management circuit (9) and the history memory (8). The history memory (8) is composed of a 1"lFO format line buffer, and stores input data in units of input lines (one row level).

The history management circuit (9) has a buffer number register (9a) indicating one line buffer in the history memory (8).
) and a character position register (9) indicating the character position in the line buffer indicated by the buffer number register (9a).
b). From the control circuit (1) to the keyboard (
The input data by pressing the key in 2) is sent to the history management circuit (9).
), the history management circuit (9) inputs the line buffer of the history memory (8) indicated by the number register (9a) into position I indicated by the character position register (9b). The stored data is stored and the value of the character position register (9b) is updated (+1).

When the end of one-line input is input (often by pressing the enter key or return key), the control circuit (+) sends that code (referred to as an end code) to the history management circuit (9), and the history management After storing the end code in the position indicated by each register (9a) (9b) of the history memory (8), the circuit (9) changes the contents of the buffer number register (9a) to a value indicating the next line buffer. Update and clear the contents of the character position register (9b).

Note that if the value of the buffer number register (9a) has already reached the preset number of line buffers in the history memory, the input data will be replaced by - line buffers, and the input data that was input one before will be , the oldest input data is deleted, and the newest input data is stored in the last line buffer.

Suppose now that a key is pressed on the keyboard (2), data is input, and the data is displayed on the CRT (5) as shown in FIG. 3A. At this time, the data input from the keyboard (2) is as shown in the history memory (8) shown in Fig. 2, as shown in the history memory (8) shown in Figure 2. ), which is stored in the history memory (8).
