Abstract

PURPOSE:To shorten a command procedure processing time by executing analytical processing prior to the arrival of a command procedure execution request and preliminarily converting each command to intermediate language. CONSTITUTION:A command preprocessor 2 analyzes a command procedure 1 and forms a command intermediate language 3. A command shell 4 executes command processing based on the formed command intermediate language 3. At the time of arrival of the command procedure execution request, only the intermediate language may be executed and the command procedure processing time can be shortened correspondingly to the unnecessary time of command analysis.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a command procedure processing method that can speed up processing time.

(Prior Art) A command procedure is a character string file that describes a plurality of processing instructions (hereinafter referred to as commands) for a computer.

Generally, commands are processed by a program called a command shell. A command shell analyzes the input command and, if it is normal, executes the specified process.

A command is a language used when humans interact with a computer, and in that sense it is different from what is normally called a program.

If you create a command sequence as a command procedure in advance, by giving the command procedure name to the command shell instead of the command name, the registered command sequence will be automatically executed, making the operator's input operation more efficient. can do well. In particular, the more commands registered in a command procedure, the more time and effort it takes to input commands.

In recent years, with the enhancement of command functions, it has become possible to implement desired processing by using command procedures instead of creating programs, and this is becoming increasingly used.

As shown in FIG. 5, conventionally, command shell processing has been performed using an interpreter method.

That is, sequentially from the command procedure file)
The commands are read out one by one (step 501) and their contents are analyzed (step 503).

If the syntax of the command is normal (step 504 YES)
), executes the process instructed by the command (step 505).

If the syntax of the command is incorrect (step 504 NO)
, outputs an error message (step 506).

By repeating the above process, all commands are processed.

(Problem to be Solved by the Invention) However, in such a conventional command procedure processing method, when a command 10 procedure execution request arrives, a process of analyzing the instruction contents of each component command, and an analysis process are performed. There is a problem in that the processing time becomes long because both the processing and the processing for realizing the action corresponding to the instruction contents are performed.

An object of the present invention is to shorten command procedure processing time in this type of computer.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention realizes a process of analyzing the instruction contents of each constituent command and an operation corresponding to the analyzed instruction contents. In the command procedure processing method, each command is converted into an intermediate language by performing the analysis process before a command procedure execution request arrives, and when the command procedure execution request arrives, It is characterized by realizing the instruction content based on an intermediate language.

(Operation) According to such a configuration, since the analysis process is completed when a command procedure execution request arrives, the processing time can be shortened by that much.

(Embodiment) FIG. 1 is a block diagram showing the configuration of a first embodiment of the present invention.

In the figure, a command procedure 1 is the same as the conventional one, and is composed of a command sequence for giving processing instructions to the computer.

The command preprocessor 2 analyzes a command procedure and generates a command intermediate language.

Command intermediate language 3 indicates a command intermediate language generated by command preprocessor 2.

The command shell 4 executes command processing using the generated command intermediate language.

Next, the operation of this processing method will be systematically explained with reference to FIGS. 2 and 3.

First, the operator creates a command procedure 1 that instructs the desired processing using a text editing program installed in the computer.

Next, specify command procedure 1 and start command preprocessor 2.

When the command preprocessor 2 is activated, one command is read from the command procedure file (step 201), as shown in FIG.

If reading is performed normally (step 202 YES)
, the command is analyzed (step 203).

As a result of the analysis, if the grammar is normal (step 204YE)
S), the command is translated into an intermediate language (step 2
05) is saved to a file (step 206).

The above operations (steps 201 to 206) are repeated until the last command in the command sequence (step 202>).

During this time, if a syntax error is found in the command, an error message is output (step 207). In this way, before a command procedure execution request arrives, analysis processing is performed and each command is converted into an intermediate language in advance. That's why I keep it that way.

Next, when an execution request arrives, a command shell is started. Then, as shown in FIG. 3, the command intermediate language is read from the file (step 301),
If the reading is normal (step 302 YES)
, the process specified in the command intermediate language is executed (
Step 303).

The above process is repeated until all command intermediate languages are read out (step 302: NO).

In this way, the command preprocessor selects the program to execute the command, checks the parameters, etc. at the translation stage, so the command shell can concentrate on the desired processing.

As a result, whereas the conventional interpreter method analyzes and executes a command procedure when a command execution request is made, in this embodiment, only execution is required, so the command procedure execution time is increased accordingly. Can be shortened.

Next, FIG. 4 is a block diagram showing the configuration of a second embodiment of the present invention.

In this embodiment, the command procedure can be executed either directly or via a command intermediate language.

In the figure, the same components as those in the first embodiment are designated by the same reference numerals, and the explanation thereof will be omitted.

The advantage of the interpreter method is that if you change a command procedure, you can immediately execute it.

Therefore, in this embodiment, in addition to the method using the intermediate language shown in the first embodiment, the conventional interpreter method is combined, so that the interpreter method can be used at the command procedure creation stage and the command preprocessor method can be used at the operation stage. ing.

Therefore, the command shell 4a is provided with the ability to process both command procedures and intermediate languages.

This requires a function to determine whether the specified file is a command procedure or command intermediate language.

To do this, the suffix of the file name should be "PPO" for the command procedure and "INT" for the command intermediate language.
You can use a method of identifying the file name, such as by using the file name, or a method of adding information inside the file to determine whether the command procedure is a command intermediate language.

[Effects of the Invention] As is clear from the above description of the embodiments, according to the present invention, when a command procedure execution request arrives, it is only necessary to execute the intermediate language, so command analysis is no longer necessary. Therefore, the command procedure processing time can be shortened.
