Abstract

PURPOSE:To realize the uniform input of data regardless of the conversion of type of the data for production by a data producer, the write address and the array of boundaries intrinsic to a device containing a data file by providing a structure definition file to a data producing device. CONSTITUTION:The structure of data is edited and decomposed by reference to a structure defining file 8 of a data producing device 10. Thus the desired data structure can be easily obtained. When plural types of data structures are required, the file 8 is prepared for each desired data structure. Then the use of a specific file 8 is instructed by a data input device 1. Thus a data producer can perform the input of data based on the type of character data regardless of the conversion of type of the data for production, the write address and the array of boundaries intrinsic to a device containing the file 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data generation device that generates data to be stored in a data file.

[Prior Art] The types of data processed by computers are divided into, for example, character data and numerical data, and numerical data is divided into, for example, decimal format data, fixed-point format data, and floating-point format data, and decimal format data. For example, the data can be divided into zone format data and pack format data.

The data type stored in the data file is stored in a data structure that allows the program that uses the data to use the data as it is read from the file. On the other hand, the type of data input from a data input device is often character data.

FIG. 2 is a block diagram showing an example of the functions of each part in a conventional data generation device. In the figure, (1) is a data input device, (2) is a data generation section, (3) is a data display section,
(4) is a data display device, (5) is a data file, (
6) is data stored in file (5), and 7) is an example of the structure of data (6). Data generation device (20
) is (1).

It is composed of the functions shown in (2), (3), and (4).

The data generation section (2) writes the data input from the data human-powered device (1) into the data file (5), and the data display section (3) writes the data input from the data human-powered device (1) into the data file (5). The data read from (5) is displayed on the data display device (4). Further, in a normal case, data input from the data input device (1) will be displayed on the display device of the data input device (1).

The data structure (7) shown in Figure 2 is REAL type data, small data 4 bytes, NTEGER type data 2 bytes, CHARA
An example of 6 bytes of CTER type data is shown.

By the way, the type of data input from the data input device (1) is generally CHARACTER type data, and the data generation device (20) has m
For example, the decimal number 10
If you want to generate and store it in data file (5), 1
You must enter hexadecimal 00OA. Also, 2.
It is quite troublesome to input floating point format data of REAL type 5.9 Even if the data generation device (20) is provided with a function to convert the data type, it is difficult to know which type to convert from to which type. , it is necessary to give an instruction from the data input device each time, and furthermore, it is necessary for the data generator to input while being directly aware of the data address. needs to be taken into account, making the structure complex.

[Problems to be Solved by the Invention] As mentioned above, in conventional devices, in order to store data in a data file in a data structure that can be used by a program as is, a troublesome input operation is required. It is conceivable that the data file side has a data structure and the data generation device side interprets it, but in this case, the program that accesses the data needs to understand the structure, so special access is required. There is a problem of having to prepare a package.

Also, when displaying the generated data, since the data generation device does not have a data structure, the generated data is typically displayed in, for example, hexadecimal, making it difficult for the data generator to see where the data ends. There was a problem that it was difficult to confirm.

This invention was made in order to solve the above-mentioned problems in the conventional ones, and the data generator inputs data in the character data type, converts the data type to generate it, writes the write address, and inputs the data. The object of the present invention is to obtain a data generation device that can input data without being aware of the boundary alignment specific to the device in which the file exists.

[Means for Solving the Problems] In the present invention, a structure definition file is provided in the data generation device, the data generation section edits input data into a predetermined data structure by referring to this definition file, and the data display section edits input data into a predetermined data structure. We decided to convert the data structure into a display data type and display it.

[Operation] In this invention, a data structure is edited by referring to a structure definition file, and it is also decomposed, so it is easy to generate a desired data structure, which eliminates the need for multiple types of data structures. In such cases, it is sufficient to provide a structure definition file for each required data structure, and to instruct which definition file to use from a data input device.

[Examples] Examples of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram showing an embodiment of the present invention. In the figure, the same reference numerals as in FIG. 2 indicate the same or corresponding parts.
) is a structure definition file, and (10) is a data generation device according to the present invention.

In the apparatus shown in FIG. 1, parts having the same reference numerals as those in the apparatus shown in FIG. 2 operate in the same manner, and therefore, redundant explanation will be omitted.

The data generation unit (2) understands the structure of the data to be generated using the yi construction definition file (8), and the data input device (1)
) is edited to match the data structure (7) and written as data (6) in the data file (5). Further, the data display section (3) displays the generated data (6) as data I? by the structure definition file (8). Ia

to be displayed.

From the perspective of a data generator, for example, when generating data with data structure 7), it is generally assumed that character data is 2.5,
10. If you input ABCDEF, the data (6) edited in the data structure (7) will be generated, and the data (6) from the data display section (3) will be changed to 2.5, 10, etc. according to the structure, for example. It is easy to understand because it is displayed as ABCDEF, and intermediate data, such as data structure (7)
When generating data in I NTEGER*2 shown in , it is possible to give an instruction such as "10 of the second data" from the data input device (1), and to input information such as the address and boundary alignment of the data. can be entered without being conscious of it.

Furthermore, even if there are multiple types of data with various structures, it is sufficient to have multiple types of structure definition files and specify the number of structure definitions. Even in such cases, you only need to specify the number of the data structure.

[Effects of the Invention] As described above, according to the present invention, since the data generation device is equipped with a structure definition file, data type conversion, write addresses, and data files for data generation by a data generator can be performed. This has the advantage of being able to generate and read data, for example, character data, without being aware of device-specific boundary alignment.
