Abstract

PURPOSE:To confirm the converting contents of a data converting device on a display screen by converting the input text data and producing the conversion data for conversion of an input file into an output file. CONSTITUTION:The input description contents are read out of an input file 11 and a parameter is detected. Then an input deciding function part 21 checks the detected parameter based on the data converted for decision of the input description contents. If the checking result is correct, the parameter is stored in a data converting device. In the same way, an output converting function part 22 receives the data consisting of the text data and including a desired irregular rule from an irregular rule definition file 24. Based on this data, the data converting data is produced for conversion of the file 11 into an output file 18. Then the output description is carried out based on the data converting data and the parameter detected out of the description contents. Thus the file 18 is produced.

EXAMPLES The present invention will be described in detail below with reference to examples.

FIG. 1 shows the basic configuration of a data conversion apparatus according to an embodiment of the present invention. In this data converter, the input file 11 is input to the input determination function unit 2
1 is input, and the input description is determined here. If there is no problem in the input description, it is input to the output conversion function unit 22, where predetermined data conversion is performed, and the output file 1
8 is created. Data necessary for determination is input to the input determination function unit 21 from the input determination definition file 23 composed of text data, and the data is converted here to determine the input description. That is, first, the input description is read from the input file 11 and the parameters are detected. Next, the detected parameter is checked using the data converted for input description determination. If the check result is correct, the parameter will be stored in the device.

Similarly, the output conversion function unit 22 is supplied with data describing desired conversion rules from the conversion rule definition file 24 composed of text data. Based on this data, data conversion data for converting the input file 11 into the output file 18 is created. An output description is performed using the data for data conversion and the parameters detected from the input description, and the output file 18 is created.

FIG. 2 specifically shows the flow of processing of the data converter shown in FIG. The input determination function unit 21 reads data for input determination from the input determination definition file 23 that defines the input determination. And
This is the input judgment data 2 of the format that has been used conventionally.
6 and the parameters in the input description 27 input from the input file 11 are checked. As such checks, there are various kinds of checks such as checking whether the default values can be omitted, in addition to checking whether the values are within the upper limit value or the lower limit value described above. What kind of check is required for the output file 18 The contents will differ depending on whether it is done. Depending on the output file 18, such a check of the input description may not be required.

If the result of the check is normal,
The detected parameter 28 is stored in the output conversion function unit 22. The output conversion function unit 22 reads out data for performing a predetermined data conversion from the conversion rule definition file 24, and converts this into conversion rule data 29 in a conventionally used format. Then, the stored parameter 28 is converted according to the conversion rule data 29. The conversion result is output to the output file 18.

FIG. 5 concretely shows the processing for creating the data conversion data similar to the conventional one from the conversion rule definition file in step S105 of FIG. First, the conversion rule for creating the current output file is read from the conversion rule definition file (step S201). A value N is prepared for sequentially processing the plurality of conversion rules and is initialized to "1" (step S202). In this state, first, the Nth conversion rule, that is, the first conversion rule here is extracted (step S203).

The extracted first conversion rule is stored in the first table as it is (step S204). Next, a search is performed in the first table, and if a control character string indicating "how to output" exists in this search, the extraction is performed (step S205). This control character string is set in the first control character string table (step S206). Since the remaining character strings in the first table are "character strings to be output", this is set in the first output table (step S207). In this way, the first
This means that three tables have been created for the conversion rule of.

Thereafter, the value N is incremented by "1" (step S208), and if the Nth conversion rule exists, that is, if the second conversion rule exists in this example (step S209; Y). Then, the process returns to step S203, and the table creating process is performed. When a table is created for all conversion rules read in step S201 in this way (step S209;
N), a series of work ends (end). After that, the output file 18 is created in the same manner as in the past, using the respective tables of “how to output” and “character string to be output” prepared for each conversion rule and the input file 11. become.

In the data converter of this embodiment, when the data for the desired output file 18 is read out from the input judgment definition file 23 or the conversion rule definition file 24 using the keyboard 43 or the mouse 42, the contents thereof are read. Can be viewed on the CRT 39, and its contents can be easily changed using the keyboard 43 or the like. Then, the contents can be registered for a new output file, and the changed contents can be immediately processed for creating the output file.

In the embodiment, the input judgment definition file 2
Since it is decided to check the data read from the input file 11 using 3, the error in the input file can be found and corrected, and the reliability of the output file 18 can be improved.

Further, in the embodiment, the conversion rule definition file 24
Data for creating a plurality of output files is stored in and can be selected with the keyboard 43 or the like. For this reason,
