Abstract

PURPOSE:To effectively understand and produce programs by setting the center viewpoint in each program understanding process as a type of the designing information and displaying selectively the contents of the corresponding designing information. CONSTITUTION:When a command is inputted from a keyboard 4 to define the type of the designing information, a control part 1 sets the type of this information based on the defining information. Then the designated part of a program text stored in a main memory 5 is defined as a program component element and this program text is turned into a tree structure when a command is inputted to define a program component element. The contents of the program component element are set for each type of said designing information. When a command is inputted to display the relevant designing information to such a defined program component element, the contents of the designing information corresponding to the relevant type are displayed on a display 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a program creation device that can effectively understand the contents of a target program and create and edit the program.

(Prior Art) Recently, a program or text indicated by a character string is inputted from a keyboard, and this program or text is memorized and displayed on a display screen, and the program or text is communicated with a programmer in an interactive manner. Program creation devices that create programs are attracting attention.

However, in conventional devices, programs and texts usually consist of sources and programs necessary to operate the system and design information necessary to understand the contents of the program, and these are mixed together. For this reason, it is extremely difficult to refer only to design information in order to create/improve a program according to a problem, and as a result, there is a problem in that it is difficult to understand the contents of the program.

Furthermore, in general, understanding the contents of a program involves referring to the functions of the entire program, referring to the structures of individual programs that implement those functions, and even referring to the control structures within individual programs. Reference design information for programs from different perspectives. However, in conventional devices, design information is uniformly processed as an unexecutable annotation, as shown in FIG. 9, for example, and therefore design information cannot be selectively referred to depending on the purpose. As a result, there is a problem in that it is difficult to understand a huge program step by step from the outline to the details and from the whole to the parts.

(Problem that the invention attempts to solve) In this way, according to the conventional programming device.

It was difficult to refer only to the design information of the program, and it was also impossible to refer to it selectively depending on the purpose, so it was not possible to understand the contents of the program step by step.

−゛ The present invention has been made in consideration of these circumstances, and its purpose is to effectively understand and edit the contents of a program while referring to program design information from various viewpoints. The object of the present invention is to provide a highly practical program creation device that can perform the following tasks.

[Structure of the invention]

Measures to solve problem C) The present invention is a program represented by an input character string.

means for storing text; means for defining the program and text as program components for each set of program descriptions; means for defining types of these program components; and means for defining the program components for each type. means for defining the position of the program component; means for defining an output format for the position of the program component for each type; and means for selectively outputting the position of the program component according to the output format. This is a characteristic feature.

(Operation) “The present invention defines a program and text indicated by an input character string as program components for each set of program descriptions, and creates a tree structure of the program and text using these program components, and The design information of the constituent elements is defined in correspondence with each stage of program understanding.Then, the selected design information of this tree-structured program is displayed and output. .

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of an apparatus according to an embodiment of the present invention.

A control unit 1 consisting of a microprocessor etc. is equipped with input/output units such as a display 2% printer 3 and a keyboard 4,
Programs and texts input by characters from the keyboard 4 are sequentially stored in the main memory 5. At the same time, the control section 1 displays the program and text using the display 2.

The control unit 1 creates and edits a target program and text according to the control flow shown in FIG. 2, for example.

The processing in this control section 1 will be explained.

When a command is entered from the keyboard 4 (step a
), the command is first analyzed (step b,
c,...,f). And if the input command is text input (step b).

A program consisting of a string of characters that is then input.

The texts are sequentially stored in the main memory 5 (step g). Furthermore, the command-processed text is displayed on the display, and step h) the first command input is waited for.

On the other hand, if the input command defines the type of design information (
Step C), the type of design information is set according to the definition information (step i). The types of design information can be defined as (1) those that explain the functions of the program, (II) those that describe the structure of the program, (lii) those that describe the control structure of the program, and (1v) those that describe the data. It is done.

If the input command indicates a definition of a program component (
In step d), the designated portion is defined as a program component, and the program and text are structured into a tree structure (step j). Furthermore, the contents are set for each type of design information in the program component (step k).
. This definition of program components is performed by dividing, for example, an input program or text into a plurality of hierarchies, and for each set of program descriptions in each hierarchy.

When a command to display the design information of the program component defined in this way is input (step e), the type of design information is specified by a subsequent input (step t). , the same content of design information corresponding to this type is displayed on the display 2 (step m).

Incidentally, when the input command instructs to output a program or text to the printer (step f), the program description of the component is output to the printer 3 (step n).

That is, when the program and text shown in FIG. 3 are input from the keyboard 4, this program and text are first displayed on the display 2.

The content of this program is to calculate the sum of data entered on the keyboard and display the result on the display. The definitions of program components and their design information will be explained below.

First, there are two sub-routines (line numbers 100-14o).

Line numbers 200 to 250) are each defined as a group of program components. In addition, line number 100~
The processing content of the description 140 is to perform keyboard input. The descriptions with line numbers 200 to 250 are for displaying the total input data.

Next, the main routine (line numbers 10 to 70) that calls the above two subroutines is defined as a program component. ,This main ,routine is defined above the above two sub ,routines in the tree structure.

The main routine and the two sub-routines are internally divided into separate program components, line numbers 30 to 60, line numbers 110 to 1) 0, and line numbers 210 to 210.
~230 is defined. The processing contents of the descriptions in line numbers 30 to 60 are to repeat the processing of the entire program and construct a repeating control structure in line number 60. The processing content of lines 110 to 1)0 is to repeat keyboard input (based on FOR, NEXT syntax), and lines 210 to 230 are to obtain the sum by repeated calculations. The three program components newly defined here are defined in the tree structure as lower-level components of the program component containing each of them.

FIG. 4 shows the text of the program that has been structured into a tree structure in this way. Once tree structuring is completed, design information will be set for each program component. The design information is defined only for related program components for each of the above types of data: (1) Program functions (1) Program structure (lli) Program control structure (1). The main routine and two sub-routines are targeted for setting design information regarding program functions. For the sub-routines with line numbers 100 to 140, the design information "data input from the keyboard" for functional explanation is set. Similarity, sub line numbers 200-250.

For the routine, "Display output sum of input data" is set. Because the main,routine calls two sub,routines.

The design information for the function explanation is set as an expression "calculate the sum" that summarizes the two design information, and represents the function of the entire program.

In the case of program structure, the objects are a main routine and two subroutines. Here, the position of program components in the program structure is set. ``Program Structure Level'' for the main routine and ``Program Structure Level'' for the two subroutines.
"Second level of program structure" is set as design information of the structure explanation.

In the case of a control structure, its classification (branch, repeat) is set between program components.

In this example, the design information "repetition control structure" is set as follows.

Between O line numbers 10 to 70 and line numbers 30 to 60, O line number 1
00 to 140 and line number 110 to 1) O line number 20 between 0
In the case of data between 0 to 250 and line numbers 210 to 230, the purpose of use (definition, storage, reference) is set. Here, ``XDATA'', which is the most important data used in FIG. 3, will be explained. “XDATA”
The program using , the text is line number 10,1
20,220, so the minimum program component line numbers containing each are 10 to 70. Line numbers 110 to 1)01 and line numbers 210 to 230 are subject to setting. For these three program components, design information that describes the purpose of data use O "Area definition" C line numbers 10 to 70) O "Input data storage" C line numbers 110 to O "Input data storage""Reference" (line numbers 210 and up) are set respectively.

The above is the process of defining program components and setting design information based on this definition. Here, the program and text are arranged in a tree structure in three hierarchical levels, but the number of hierarchical levels is determined depending on the content of the program.

By the way, with this device, by inputting the above-mentioned command,
One selection of design information required at each stage of program understanding is displayed. FIGS. 5 to 8 show examples of the display screens.

Thus, according to this display method, it is possible not only to know the program description of the program component that is the target of content understanding, but also to understand the design information that corresponds to the central viewpoint at each stage of program understanding. By referring to , it becomes possible to easily understand the positioning of the program components.

In other words, it has great practical effects, such as greatly aiding the understanding of program contents.

Note that the present invention is not limited to the embodiments described above. For example, the definition of program components.

It should be determined according to the program.

Furthermore, the program components defined at - degree are further added to the layer 1-+. It is also possible to construct a more detailed tree structure.

Further, the present invention can process databases and texts. In this case, it becomes possible to refer to the contents of the database from various viewpoints. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

〔Effect of the invention〕

Thus, according to the present invention, the central viewpoint at each stage of program understanding can be set as the type of design information, and the contents of the design information corresponding to this can be selectively obtained.
It becomes possible to understand and create programs in an interactive format extremely effectively. In other words, while understanding the entire tree-structured program and text, it is possible to refer to the design information of the program components according to the purpose, which is of great practical use, such as greatly assisting in understanding the program contents. This produces a certain effect.
