JPS63247847A - System for preserving input data history - Google Patents

Abstract

PURPOSE:To realize the use of the input data obtained in a preceding start state and also the use of the hitherto input data despite occurrence of the abnormality, by constituting a history holding device with a nonvolatile memory and preserving the input data. CONSTITUTION:The input data supplied from an input device 1 is stored in an input receiving part 2. Then this input data is delivered to an input data processing part 5 and also to a history writing part 3. The delivered data is stored in a nonvolatile history holding device 4. When the re-execution of a history is designated by the input data, the part 2 gives a read request to a history reading part 6. The part 6 reads the history out of the device 4 and delivers it to the part 5. The part 5 carries out the history processing when an input is received from the device 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a user interface in a computer system, and more particularly to a method for storing data history from a user.

[Conventional technology]

Conventionally, this type of input data history storage method was to store input data in a memory area secured by a certain application software.4For example, Unix (BSD version) csheLL
There is a history function in .

[Problem that the invention seeks to solve]

The conventional input data history storage method described above has the disadvantage that the input data history, that is, the history, is stored in a volatile memory, so that when the system is restarted, the input data history from the previous startup cannot be used.

[Means for solving problems]

The present invention includes a history writing section for writing input data inputted by an input data receiving section into a non-volatile history holding device, a history reading section for reading out the saved history for reuse, and a history reading section for reading input data and reading out the stored history. It has an input data processing unit that processes the history.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of the present invention. As shown in FIG. 1, input data input from an input device 1 such as a keyboard is received by an input data receiving section 2. The input data receiving section 2 passes the input data to the input data processing section 5 and also to the history writing section 3. The history writing section 5 stores input data in a nonvolatile history holding device 4 consisting of a battery-backed RAM or the like. When the input data specifies re-execution of the history, the input data receiving unit 2 uses the history reading unit 6.
Make a read request to. The history reading unit 6 reads the history from the history holding device 4 and passes it to the input data processing unit 5. The input data processing unit 5 executes history processing corresponding to a command or the like when an input is received from the device 1.

〔Effect of the invention〕

As described above, the present invention allows previously input data to be easily re-input by saving the input data. Furthermore, since the history holding device is non-volatile, the input data from the previous startup cannot be used, and even if the system or application program becomes abnormal, the input data up to that point can be used.
