Abstract

PURPOSE:To enable a user to freely use the commands with customization by converting a command train proper to the user and inputted through a terminal into a standard command train by a pre-command interpreter and then analyzing the command train by a command interpreter respectively. CONSTITUTION:A user registers previously the relation between a command train proper to the user and its corresponding standard command train to a pre-command interpreter 3 of an electronic computer 1. Then the user inputs these command trains through a terminal 8, and a terminal input/output part 2 of the computer 1 receives the command trains. Then the interpreter 3 converts the command train proper to the user and inputted through the terminal 8 into a standard command train. Meanwhile a command interpreter 4 analyzes the standard command train and selects and starts a command processor 5 corresponding to the requested processing out of a command processor group 6. Thus the user can freely input the commands in a customized format.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pre-command interpreter method in an electronic computer system.

[Conventional technology]

Computer systems that are connected to terminals via communication lines and that fulfill requests from users by inputting commands from the terminal generally include a command interpreter that analyzes commands and executes processing that corresponds to the commands. Equipped with multiple command processors.

By the way, since command interpreters are used for general purposes, the commands that can be input are standardized, so users can perform the desired processing according to the specified formal command input format. It was used to enter a command string to perform the command.

[Problems to be Solved by the Invention] As mentioned above, in conventional computer systems, users were able to perform desired processing by combining standardized commands. Since commands must be input according to the specified input format, the command input method can be customized if you want to input a fixed pattern for each application, or if you want to input commands in a personal format. It had the disadvantage of being inflexible and unable to respond to people's requests.

The present invention has been proposed in view of the above points, and its purpose is to provide a pre-command interpreter system that allows users to freely customize and use commands.

[Means to solve the problem]

In order to achieve the above object, the present invention includes: a terminal input/output unit that performs input/output with a terminal; a pre-command interpreter that converts a user-specific command string input from the terminal into a standard command string; and a command string. It is equipped with a command interpreter that analyzes the command, and a command processor that executes processing corresponding to the command.

[Operation] In the pre-command interpreter method of the present invention, the terminal input/output unit performs input/output with the terminal, and the pre-command interpreter converts a user-specific command string input from the terminal into a standard command string. Then, the command interpreter analyzes the command string, and the command processor executes processing corresponding to the command.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a computer system to which the pre-command interpreter method of the present invention is applied.

In FIG. 1, a terminal 8 is connected to a computer 1 via a communication line 7, and these constitute a computer system. The computer 1 also includes a terminal input/output unit 2 that performs input/output with the terminal 8, a pre-command interpreter 3 that converts a user-specific command string input from the terminal 8 into a standard command string, and a command string. It includes a command interpreter 4 that analyzes commands, a command processor 5 that executes processing corresponding to commands, and a command processor group 6 that is a collection thereof.

FIG. 2 shows an example of the operation of the above embodiment, and the operation of the embodiment will be explained below with reference to FIGS. 1 and 2.

The user registers in advance in the pre-command interpreter 3 of the computer 1 the relationship between the user-specific command string and the corresponding standard command string.

For example, a standard command string represented by jklm, n, o, p, q is associated with user-specific command strings such as abc d, e, f. Note that the registered contents can be changed at any time.

Thereafter, as shown in FIG. 2, when the user inputs a command string, for example, abc d, e, f, from the terminal 8, the terminal input/output section 2 of the computer 1 receives the command string.

The terminal input/output unit 2 determines whether or not the user has registered the pre-command interpreter 3, and if so, passes the received command string to the pre-command interpreter 3. If it is not registered, it is passed directly to the command interpreter 4 as usual.

The pre-command interpreter 3 that has been passed the command string,
The command string is analyzed, and in this example, since the corresponding command string is registered, the standard command string jklm, n, o, p, q corresponding to that command string is passed to the command interpreter 4. Note that if the corresponding command string is not registered, it is passed directly to the command interpreter 4.

The command interpreter 4 to which the standard command string is passed analyzes the command string, selects and activates a command processor 5 corresponding to the requested processing from the command processor group 6.

The activated command processor 5 executes the corresponding process (command) and passes the execution result to the terminal input/output unit 2.

The terminal output unit 2 returns the passed execution result to the terminal 8.

〔Effect of the invention〕

As explained above, in the pre-command interpreter system of the present invention, the user can input commands in a freely customized format. This has the effect of greatly improving usability when it is desired to input commands in a free form.
