Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an interactive program processing method,
In particular, the present invention relates to an interactive program input processing method that determines whether a sentence is correct or incorrect each time it is input through an input means.

[Background of the invention]

In recent years, keyboards and displays have been used as data input and confirmation means, and in addition to inputting desired data from the keyboard, data can be input and processed in an interactive manner while referring to the input status or processing results displayed on the display. A system that performs this has been put into practical use.

The most well-known systems of this type are airline and railway seat reservation systems.
An operator performs reservation processing in an interactive manner while inputting reservation information through an input device.

Furthermore, as this type of system, a so-called interactive program input and processing system in which a program is created by sequentially inputting sentences, words, etc. constituting a program from an input device is being put into practical use.

In such conventional systems, errors in each input sentence can be detected. However, it is difficult to say that there is compensation as to whether or not the types of variables included in the input text match the types defined in the input text. In fact, it is presumed that conventional systems of this type have not yet reached this point.
The reason is that to determine type matching,
It is necessary to register the types of variables used, and when a new sentence is input, to compare it with the type of the already registered sentence. Moreover, registering and managing this type is extremely difficult. This is because it is considered to be difficult.

On the other hand, such interactive program input and processing systems are increasingly being required to be able not only to simply input sentences but also to freely delete inputted sentences. In this case, even if a type has been registered for a variable, if all sentences that use that variable are deleted, the already registered type must be deleted. Usually, variables are used in multiple sentences, so to cancel a registered type, it is necessary to examine all the input sentences, which takes a lot of time.
Moreover, the responsiveness of program input operations becomes significantly worse.

Therefore, in such a system, each
The system does not check whether the variable type is correct or incorrect when one sentence is input, but performs this type of judgment all at once after all sentences have been input, that is, after the entire program has been input. . Therefore, if the same variable is accidentally used in multiple types,
All sentences that use that variable must be checked and corrected. The number of man-hours required for program modification is 200 to 300 per day for a typical programmer.
It is considered to be about a line, so if there is an error in the use of a major variable type in a program that spans several thousand steps, it will take several hours to a day to correct it. Moreover, when there are many corrections, situations may occur where people forget to make corrections or end up re-editing what has already been corrected.

[Purpose of the invention]

Therefore, an object of the present invention is to eliminate the above-mentioned drawbacks, to easily determine the correctness of the constituent sentences of an input program, including the types of variables, and to reduce the number of man-hours required for correction. The object of the present invention is to provide a greatly reduced interactive program processing method.

[Summary of the invention]

Thus, the present invention is realized in an interactive program input and processing system that converts the constituent sentences of a program input through an input means such as a keyboard into internal code and stores the internal code. That is, it has a table that registers at least the names including variables used in sentences constituting the program and the frequency of use of the names, and the table is updated every time a new sentence is input from the input means. Search, determine whether the name in the text has already been used elsewhere, and if so, update the frequency of use of the name. On the other hand, if it is determined that the name has not been used elsewhere, the name is newly registered in the table. After that, the input program is converted into internal code. Also, when deleting a certain sentence, when the frequency of use of the name used in the sentence reaches a predetermined value, for example "0", the name is considered not to be used in other sentences. , the text will be canceled.

[Embodiments of the invention]

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

FIG. 1 is a diagram showing the configuration of an interactive program input and processing system for explaining an embodiment.
In this figure, the input display section 1 consists of a display 11 and a keyboard 12.
From 2, various data such as sentences constituting the program and function information are input. The display 11 also displays data entered from the keyboard 12 for confirmation,
The results of processing data from the processing unit 2, which will be described later, are displayed.

The processing unit 2 analyzes sentences input from the keyboard 12. If there is an error as a result of this analysis, a message is output to the input display section 1 and an error is displayed on the display 11. Here, the analysis of the input text can be easily realized using a technique used in a normal compiler, that is, according to the grammar of the programming language. On the other hand, if the analysis result is correct, the input text is converted into internal code. The text converted into this internal code is stored in the internal code buffer 3.

The processing unit 2 also performs processing for updating and canceling data in the table 4, which will be described later.

Table 4 is configured in memory,
The format consists of a counter section that holds the name contained in the text, its type, and the number of times the name is used.

Next, the processing operation of the system having such a configuration will be explained. First, the normal processing operation for input sentences will be explained with reference to the flowchart shown in FIG.

When a sentence is input from the keyboard 12, the processing unit 2 analyzes the input sentence according to the grammar of the language of the program. If an error is found as a result of this analysis, an error message is returned and the display 11 indicates the fact. Then, for example, guidance is displayed to prompt the user to input the text again.

On the other hand, if it is determined that the syntax of the input sentence is correct as a result of the above analysis, it is checked whether the name used in the sentence has already been registered in the table 4. If it is found by searching the table 4 that the item does not yet exist in the table 4, the name, its type, and the number of times it has been used (in this case, "1" because it is the first time) are registered in the counter section. On the other hand, if the name is already registered in Table 4, the type corresponding to the registered name is compared with the type used in the currently input text, and if they match, , it is assumed that the type corresponding to the name is normal, and the inside of the counter section is updated, that is, plus "1". On the other hand, when comparing the types, if the two do not match, it is determined that there is a mismatch error in the type corresponding to the name. The result of this judgment is sent to the display 11 and displayed accordingly. The operator looks at this, double-checks the type, and re-enters the text.

In this way, the processing unit 2 checks the syntax, the names including variables used in the syntax, and their types, and
The contents of table 4 are updated according to the check results. If the series of checks is correct, the input text is converted into an internal code,
The result is stored in the internal code buffer 3.

Next, processing operations when a text is deleted will be described with reference to the flowchart shown in FIG. When a command to be deleted and a sentence to be deleted are specified from the keyboard 12, the processing unit 2
extracts the internal code of the specified text from the internal code buffer 3. Also, from Table 4, the names used in the text and their related information are extracted. Then, set the contents of the counter section to “1”
At the same time as subtracting, it is checked whether the value of the counter section is "0" or not. If the value is other than "0", it indicates that the name is still being used in another sentence, so it is assumed that the process related to the name in Table 4 remains unchanged, that is, it is continuing. Only the internal code of the text is deleted from the internal code buffer 3. On the other hand, if the value of the counter section is "0", this means that there is no other text using that name, so the name and related information are deleted from Table 4. After processing this table 4, the internal code of the text is deleted from the internal code buffer 3.

〔Effect of the invention〕

As explained above, according to the present invention, each time a certain unit, for example, one unit of text is input, it is determined whether a name including a variable used in that text is correct or not, and as a result, it is determined whether the name is correct or incorrect. For example, since a correction operation such as re-input is prompted at that point, correction work can be performed each time. Therefore, the program can be executed immediately after all the sentences have been inputted, and the effort of checking all the sentences for correction work as in the prior art is saved, and the corrections do not lead to further errors. There will be no need to wake up.
