The magnetic disk device 3 stores a form layout for each attribute of a data set, a program for causing the processing unit 6 to perform a predetermined process, and a format description used when creating a format description. At the time of creation, a description table or the like in which a description described in association with the data name is registered in association with the data name is stored.

The processing unit 6 has a function of checking whether or not the format of the file stored in the memory 2 by the input control unit 1 is the HDF format, and a case where the format of the file stored in the memory 2 is the HDF format. Is a function for extracting the contents of data elements predetermined according to their attributes from each data set in the file, the contents of the data elements extracted from each data set, the attributes of each data set, Has the function of creating print data for a format description based on the form layout defined in the above and the contents of the description table, and outputting the print data to the printer control unit 4.

The printer control unit 4 has a function of controlling a printer (not shown) in accordance with print data output from the processing unit 6 to create a format description.

Next, the operation of this embodiment will be described.

When creating a format description, the user uses the operation unit 5 to specify a file (HDF file) for which the format description is to be created.

When a file is specified, the input control unit 1 inputs the contents of the specified file and stores it in the memory 2 (S21 in FIG. 2).

When the contents of the file are stored in the memory 2, the processing unit 6 sends the file
It is checked whether it is a format (S22).
The HDF format file is as shown in FIG.
It is composed of a header, a DD block, and a data element. Since “NCSA” is set in the header,
Whether or not the file is an HDF format file can be checked based on whether or not “NCSA” is set in the header.

If it is determined that the format is not the HDF format (S23: NO), the processing unit 6 displays an error on a CRT (not shown) provided in the operation unit 5 (S28), and informs the user. Notifies that the file specification is incorrect.

On the other hand, when it is determined that the format is the HDF format (YES in S23), the processing unit 6
Step 24 is performed.

In S24, H stored in the memory 2
Attention is focused on one data set in the DF file, and its attribute is identified. Here, as shown in FIG. 3, one data set includes a plurality of DDs sandwiched between the DDH and the next DDH, and data elements indicated by the respective DDs. The first data element shown in FIG. 3 includes five DDs and five data elements pointed to by the five DDs. Also, each DD is Tag,
Ref, Offset, and Length, and the attribute of the data set can be identified based on the combination of the tags of the DDs in the data set. That is, in S24, the attributes of the data set are identified based on the tags of a plurality of DDs existing in the data set of interest.

When the attribute of the data set is identified in S24, the processing unit 6 extracts the contents of the data element which is predetermined according to the attribute among the data elements existing in the data set. The description registered corresponding to the data name of the data set is taken out from the description table in the magnetic disk device 3, the contents of the data element extracted from the data set, the description taken out from the description table, and the attributes of the data set Are stored in the magnetic disk device 3 in association with each other (S25). For example, when the attribute of the data set is “A”, the contents of all data elements in the data set are extracted, and when the attribute is “B”, only the contents of some data elements in the data set are extracted. Processing such as extraction is performed according to the attributes of the data set. Here, the process of extracting only the contents of some data elements is performed, for example, on a data set including image data (it is possible to determine whether or not such a data set is based on an attribute). Is what is done. The location of the data element from which the content is extracted is determined by Offset, Leng in the DD.
It can be easily obtained based on th.

Now, for example, the five DDs shown in FIG.
Assuming the first data set composed of five data elements, the following processing is performed.

In S24, the processing section 6 identifies the attribute of the first data set. Now, for example, it is assumed that the attribute of the data set is “A” first.

If the attribute of the data set is "A", as described above, the contents of all data elements in the data set are extracted.
Is the content "Sa" of the five data elements shown in FIG.
ttelite "," 1 "," char "," 4 ",
“SAT” will be extracted. Further, in S25, a description (hereinafter, referred to as “satellite name”) registered in the description table corresponding to the data name “Satelite” is acquired, and the attribute “A” and the content of the data element “Satelite” are acquired. , "1", "char",
“4” and “SAT” are associated with the description “satellite name” extracted from the description table and are stored in the magnetic disk device 3.

When the processing in S25 is completed, the processing unit 6
It is determined whether an unprocessed data set exists in the HDF file (S26).

If it is determined that there is an unprocessed data set (S26: YES), the same processing as described above is performed by focusing on one of the unprocessed data sets (S24, S25). .

On the other hand, if it is determined that there is no unprocessed data set (S26: NO), a format description creation process is performed (S27).

In the format description creation process in S27, the processing section 6 performs the following process.

First, as shown in the flowchart of FIG. 4, attention is paid to one of the attributes of a plurality of data sets (S4).
1).

Next, a form layout and storage data corresponding to the above attributes are obtained from the magnetic disk device 3 (S
42, S43) Further, print data is created for the format description based on the acquired form layout and the stored data, and the created print data is output to the printer control unit 4 (S44). Upon receiving the print data from the processing unit 6, the printer control unit 4 causes a printer (not shown) to print the print data. This allows
The part related to the above attribute of the format description is printed.

Thereafter, the processing section 6 determines whether or not there is an unprocessed attribute (S45). Then, when there is an unprocessed attribute (YES in S45), one of the unprocessed attributes is noted, and the same processing as described above is performed (S45).
41 to S44). On the other hand, when it is determined that there is no unprocessed attribute (S45: NO), the process ends.

FIG. 5 is a diagram showing an example of a part of the format description created as described above (an example of a print result relating to a certain attribute). The description in the first description line of the format description shown in FIG. 5 corresponds to the first data set shown in FIG. 3, and the data name is “Satelite”, the number of data is “1”,
The data type is “char”, the size is “4”, and the content of the data is “SAT”. The description “satellite name” indicates that the content of the data set is a satellite name.

FIG. 6 is a block diagram showing an example of the hardware configuration of the format manual creating apparatus shown in FIG. 1. The computer 61, the recording medium 62, the storage device 63, and the operation unit 64 It is configured.
