Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic label name generation system, and particularly when a program is created using parts.
The present invention relates to a label name automatic generation method in which a label name that is unique in a program is created and incorporated when a component using a label name in a description is quoted multiple times.

[0002]

2. Description of the Related Art Conventionally, a method of preparing a set of processing descriptions defining a certain processing procedure in advance as software parts (hereinafter simply called parts) and creating a program by quoting these parts is a program. Is widely used to facilitate the creation of. In this case, the same label name (identification name given to a specific process description for facilitating branching, etc.) cannot be used in duplicate in the same program due to the restrictions of the programming language, and the same in the same program. Considering that there is a high possibility that a part will be quoted multiple times, the description using the label name is not performed in the part, or the edit information written as an argument of the call statement is written in the program of the part expansion destination. A general method is to devise the description inside the component so that a unique label name is generated based on it.

[0003]

The above-described conventional method of making and using the parts has the following problems.

First, if the label name is not used during the description of the part, it is not possible to easily branch to an arbitrary place, so that the free use of the programming language is restricted when creating the part, and the same. Since the process description is described in multiple places in the same part, it becomes large-scale and complicated. To avoid this, if the parts themselves are divided into small-scale processing units, it is inconvenient because it is necessary to quote a large number of the divided parts. In addition, if a large number of parts are created, the relationship between the parts and other aspects will increase. The rate of making mistakes also increases.

Secondly, when editing information is given from the outside to generate a unique label name, in addition to the original process description for developing in the program, the editing information given from the outside with respect to the label name generation is added. It is necessary to describe in the part the process of receiving the label and the process of generating the actual label name from the received edit information. Therefore, a certain amount of ingenuity is required when creating a component, which is a burden on the component creator. Further, since the editing information given from the outside is different for each part, it is necessary for the program creator who uses the part to manage the editing information and avoid duplication of label names.

An object of the present invention is that a program creator can freely quote a part only by the part name without being aware of the label, and a part creator can easily create a part using a label during description. It is to provide an automatic name generation method.

[0007]

According to the automatic label name generation method of the present invention, a program development support system for creating a program by quoting a prepared part consisting of a group of process descriptions defining process procedures. At
Temporary label name search means for determining the type of the variable by searching the temporary label name from the part including the temporary label name consisting of the fixed part and the variable in the description, and the total number of times of use of all parts in the same program To store the total component usage information table, the usage information table for each component that stores the usage count information for each component in the same program, and the total component usage information table and usage by component by detecting the component call statement in the program Corresponding from the total component use information table or the component-specific use information table corresponding to the component name and variable type information from the temporary label name search means, and component information setting means for setting the number-of-uses information in the information table, respectively. Variable value returning means for extracting the number-of-uses information, information on the fixed part from the temporary label name searching means, and the variable value returning means It is constituted by a label generating means for generating a unique label name by combining the usage count information in the program from the stage.

[0008]

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The automatic label name generation system of this embodiment is shown in FIG.
As shown in FIG. 2, a part 1 in which a description of a temporary label name including a fixed part and a variable is included and the description is expanded in the program by being quoted from the program, and a description of the temporary label name is extracted from the part 1. Then, the provisional label name search means 2 for analyzing the components of the provisional label name to determine the type of the variable, the total component use information table 4 for storing the use count information of all the components in the same program, and the same program The usage information table 5 for each part that stores the usage frequency information for each part in the component, and the usage frequency information is set in the total component usage information table 4 and the usage information table by component 5 each time a component call statement in the program is detected. The component information setting means 6 to be updated, and the total component usage information table 4 or the components corresponding to the component name and variable type information from the temporary label name retrieval means 2. Variable value returning means 3 for extracting the corresponding usage count information from the usage information table 5, and a program in which the usage count information from the variable value returning means 3 is reflected in the variable in the temporary label name from the temporary label name search means 2. And a label name generating means 7 for generating a unique label name.

FIG. 2 is a flow chart showing the flow of processing of this embodiment. The operation of each unit in FIG. 1 will be described below with reference to FIG.

First, the user reads and prepares the component 1 prepared so that the temporary label name consisting of a fixed character string and a variable becomes a unique character string in the component from a component library or the like (step 21).

Next, in the process of expanding the description of the component in the program created by quoting the component, when the call statement of the component described in the program is recognized (step 22), the component information setting means 6 Sets the total number of times of use of all the parts in the program to the total parts use information table 4 and updates them each time (step 23). At the same time, the number of times of use for each part is set in the part-by-part usage information table 5 and updated based on the part name of the part to be quoted shown in the call statement (step 2).
4).

Next, the part 1 for which the quotation is instructed is read (step 25), and the temporary label name search means 2 searches for and extracts the temporary label name described in the part, and the components of the temporary label name. And the variable type return information to the variable value return means 3, and the description image of the fixed character string and position information of the variable embedded in the fixed character string to the label name generation means 7 (step 26). Here, the variable that can be described in the temporary label name together with the fixed character string is either the total usage count value of the component in the same program or the usage count value of the relevant component in the same program.

Next, the variable value returning means 3 refers to the total component usage information table 4 or the component-specific usage information table 5 according to the variable type information passed from the temporary label name searching means 2, and refers to the variable value for the variable. Is returned to the label name generating means 7 (step 27).

Finally, the label name generating means 7 is obtained by the variable value returning means 3 and the description image of the fixed character string analyzed by the temporary label name searching means 2 and the embedded information in the fixed character string. A unique label name is generated based on the variable value (step 28) and is expanded in the program together with other descriptions in the part (step 29).

FIG. 3 shows a specific example in which a temporary label name in a part is quoted by a program to generate a unique label name. When a label is used in a part, a fixed character string “PAT1-LBL” is used as indicated by reference numeral 31.
-"And a variable"& SYSGCCN "that indicates the total number of times the parts have been used
A temporary label name composed of T "is defined as a unique character string in the part.

When this part is expanded in the program by the automatic label name generation method of the present invention, the fixed character string is expanded as it is, but the variable reflects the total number of uses of the part in the program, and the first part A unique label name is generated using the value "1" for quotation and the value "2" for the second part quotation as the value of the variable "&SYSCNTNT".

That is, if the first citation of this part is the first part citation in the program, the expanded label name is "PAT1-LBL-" as shown by reference numeral 32.
1. However, if the second reference to this part is the third reference as a program with reference to another part in the middle, as indicated by reference numeral 33, “PAT1-LBL-3. "It becomes.

If the temporary label name is composed of a fixed character string and a variable indicating the number of times of use for each part, the numerical value added after the fixed character string in the second citation in the example of FIG. Becomes "2" instead of "3". Which one is used as a variable depends on the selection of the component creator, but if a variable that represents the total number of times a component is used is used, the temporary label name of the same fixed character string is used between multiple components. However, since it is expanded as a unique label name, there is an advantage that no trouble occurs.

[0021]

As described above, according to the automatic label name generation method of the present invention, the program creator who cites a part needs to consider the label name even when the same part is developed a plurality of times in the same program. However, if a part name is specified and quoted, a unique label name is automatically generated and developed for the same program, so that there is an effect that parts can be freely quoted.

Further, when a description is made by using a label in a part, the description can be made in the same format as usual only by using a temporary label name to which a variable is added, so that a control error may occur due to the description. There is little, and there is an effect that improvement of maintainability can be expected.
