Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an editor for displaying and editing a control structure of a program with graphic symbols.

In order to improve the productivity of program development, an instruction is represented by a graphic symbol to clarify the control structure of the program and to prevent errors in the control structure of the program. Since such an editor cannot store the graphic symbol program in a special format and therefore cannot be distributed as it is, it is desired to solve this problem.

[0003]

2. Description of the Related Art Conventionally, a distribution program described according to a language specification and a graphic symbol program in which a control structure of the program is expressed by graphic symbols are programs of different formats. For this reason, in general, when attempting to translate by a compiler, the graphic symbol program is first converted into a distribution program and then translated. On the contrary, when attempting to use or modify the distribution program, the distribution program is once converted into a graphic symbol program, which is displayed on the screen for creation or modification.

[0004]

As described above, conventionally, the control structure of a program is displayed as a graphic symbol program on a screen using a graphic symbol and is modified, or a graphic symbol program is created on the screen. , Was saved as a graphic symbol program. Also, if you want to use a distribution program written in the specifications of the programming language, you need to convert this distribution program to a graphic symbol program once each time and display the converted graphic symbol program on the screen to make corrections. , Change, etc. After correction or change, save this graphic symbol program. In the case of translation by a compiler, the saved graphic symbol program is once converted into a distribution program and then translated to create an executable module. Therefore, when trying to use the distribution program, each time the user needs to perform an operation instruction for converting the distribution program into the graphic symbol program and a conversion process for that, and once the conversion is performed, the screen is converted. When translating a graphic symbol program that has been modified or created above, it is necessary to perform an operation instruction for converting the graphic symbol program into a distribution program and the conversion process for that, and then perform the translation to create an executable module. However, there is a problem that the user requires an extremely complicated operation. Further, since the graphic symbol program is stored, there is a problem that the distribution property is poor and the version numbers of the graphic symbol program and the distribution program are different.

The present invention solves these problems.
The editor has a function to automatically convert the distribution program to a graphic symbol program and display it, and to automatically convert the edited graphic symbol program to a distribution program and save it. The purpose is to ensure easy distribution and to save the distribution by a distribution program.

[0006]

[Means for Solving the Problems] Means for solving the problems will be described with reference to FIG. In FIG. 1, the distribution program 11 is a program that does not have information of structural notation, and is a program described based on, for example, the convention of the programming language.

The graphic symbol program 12 is a program in which the control structure of the program is expressed using graphic symbols. In the conversion process 2, the distribution program 11 is converted into the graphic symbol program 1
It is converted into 2.

The conversion processing 3 converts the graphic symbol program 12 into the distribution program 11. Display processing 4
Displays the graphic symbol program 12 on the screen using graphic symbols.

[0009]

According to the present invention, as shown in FIG. 1, the distribution program 11 for which the conversion processing 2 is instructed is converted into the graphic symbol program 12, and the display processing 4 converts the converted graphic symbol program 1.
2 is displayed on the screen using graphic symbols, and the user edits (creates, corrects, etc.) this graphic symbol program 12 from the screen.
In response to this, the conversion processing 3 converts the edited graphic symbol program 12 into the distribution program 11 and stores it.

Therefore, the editor is provided with a function of automatically converting the distribution program 11 into the graphic symbol program 12 for display, and having a function of automatically converting the graphic symbol program 12 after editing into the distribution program 11 and storing it. It becomes possible to easily handle the distribution program 11 as the graphic symbol program 12 without being aware of it, and at the same time, it is possible to save the distribution program 11 and secure the distribution property. In addition, the distribution program 11
By storing the file in the above manner, it is possible to prevent the version number deviation between the conventional graphic symbol program and the distribution program.
