Abstract

PURPOSE:To facilitate the easy definition of a file and to decrease the file definition errors by supplying the data needed for file definition and collating the data with the contents of a data item dictionary memory part. CONSTITUTION:An input part 1 is connected to an input check part 2, and the part 2 is connected to a processing part 4. While a data item dictionary memory part 3, a converting part 5 and a file definition storing part 6 are connected to the part 4. The data supplied from the part 1 are checked by the part 2 and given to the part 4. The part 4 collates the input data with the contents of the part 3 to produce the file definition and registers this definition to the part 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to program control in a data processing device, and particularly to a file definition method in a program.

(Prior Art) Conventionally, file definitions in programs have been defined either directly within the program or by reusing files previously defined in other parts.

(Problems to be Solved by the Invention) The former method has disadvantages in that it takes time and effort to create a file definition, and there are many errors in the created file definition. In addition, the latter method has the disadvantage that it is necessary to create and prepare in advance what is expected to be necessary, and that scalability is low.

An object of the present invention is to eliminate the above drawbacks by inputting data necessary for a file definition and comparing it with the contents of a data item dictionary storage unit, thereby making it possible to easily generate error-free file definitions. The objective is to provide a structured file definition method.

(Means for solving the problem) The file definition method according to the present invention includes an input check section,
It is configured to include a file definition storage section, a data item dictionary storage section, a processing section, and a conversion section.

The input check section is for checking input data describing data items before inputting them.

The file definition storage section is for registering file definitions.

The data item dictionary storage section stores contents including at least a general name, a data name, and a data size.

The processing section is for determining whether or not the data added to the input checking section is the same as the file definition registered in the file definition storage section or the contents of the data item dictionary storage section.

The conversion unit stores the file definitions determined to be the same by the processing unit in the header data area, and sequentially stores the contents of the data item dictionary storage unit in the corresponding positions in the file definition storage unit. It is for performing conversions.

(Example) Next, one embodiment of the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment for implementing the file definition method according to the present invention.

In FIG. 1, 1 is an input section, 2 is an input check section, and 3 is an input section.
is a data item dictionary storage unit, 4 is a processing unit, 5 is a conversion unit, 6
is the file definition storage.

In FIG. 1 showing an embodiment of the present invention, an input section 1 is connected to an input check section 2. As shown in FIG. The input checking section 2 is connected to the processing section 4, and the processing section 4 is connected to the data item dictionary storage section 3, the conversion section 6, and the file definition storage section 6.

FIG. 2 is an explanatory diagram showing a description example of data items input from the input section 1. FIG. 8 is an explanatory diagram showing an example of the format of data input to the conversion unit 6 and the file definition storage unit 8.

In FIG. 1, from the input section 1, data (a) to
When (C) is input, the input checking section 2 also performs a check in the first step. In the second step, the data (a
) is added to the processing unit 4, the file definition storage unit 8 determines whether the data is registered data, and the conversion unit stores the data in the data area shown in FIG. 8th
In step, the data (b) checked by the input checking section 2 is sent to the data item dictionary storage section 3 via the processing section 4, and it is determined whether or not the same data (b) exists there. . The data (
If data b) exists, the contents of data (b) are sent to the conversion unit 5 via the processing unit 4, and the data item Nn(
n=1°2, . . . n).

On the other hand, in the fifth step, if data (b) does not exist in the data item dictionary storage section 3, data (C) is input from the input section 1. Data (e) is input check section 2
The information is checked by the processing section 4, registered in the data item dictionary storage section 5 via the processing section 4, and stored in the same manner as in the fifth step. In the sixth step, the eighth to fifth steps are repeated until end data is input. In the seventh step, the data corresponding to FIG. 8 stored in the conversion section 6 is registered into the file definition storage section 6 via the processing section 4.

The contents of the file definition storage section 8 described above in this embodiment are used as file definition statements when creating a program.

(Effects of the Invention) As explained above, in the present invention, by inputting data necessary for file definition and comparing it with the contents of the data item dictionary storage section, file definition is facilitated. Since errors are reduced, file definitions can be easily generated if data similar to that input in the data item dictionary storage unit is registered, and errors in programs can be prevented. be.
