Abstract

PURPOSE:To make work for generating a program at every concrete conversion example unnecessary by storing in advance information of a conversion format of a file in a conversion table. CONSTITUTION:A conversion control part 4 fetches converting information by one piece each from a conversion table storage part 3 having a conversion table in which several groups of an input column position (a), an input column number (b), and delimiter information (c) are arranged, and sends (a) and (b), and (c) to an input processing part 2 and an output processing part 5, respectively. Whenever (a) and (b) are received through a transmission line 10, the processing part 2 sends the contents of a designated position in an input buffer to the processing part 5. The processing part 5 puts in the contents of a data which is sent, by delimiting them by said (c). When the data comes not to be sent through the transmission line 10, the contents of an output buffer are written in an output file.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a file conversion method, and particularly to a file conversion method for converting a file format suitable for one use into a file format suitable for another use.

[Conventional technology]

Conventional file conversion methods deal with this by creating a program for each specific example.

[Problem that the invention seeks to solve]

Therefore, in the conventional file conversion method described above, a program must be created for each specific example of conversion, which has the disadvantage of increasing the cost of creating the program.

[Means for solving problems]

The file conversion method of the present invention includes an input processing section, an output processing section, a conversion table storage section, and a conversion control section.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention.

The file conversion method shown in Figure 1 uses fixed format files (
It converts files whose positions are fixed (fields are fixed) into variable format files (fields are separated by delimiters and arranged in arbitrary lengths).

The input processing unit 2 inputs records from the input file 1 through the data transfer path 7 code by code. Conversion control unit 4
takes out the conversion information one by one from the conversion table storage unit 3 through the data transfer path 9. As shown in Fig. 2, the conversion table is made up of several sets of ICs lined up with input input ram position a, input column number b/, delimiter information, input column position a, input column number b, and delimiter information. This is a set of delimiter information C. Every time the conversion control unit 4 takes out a set of conversion information, it sends the input column position a and the input column number to the input processing unit 2 through the data transfer path 8 to the data transfer path 12.
The delimiter information C is sent to the output processing section 5 through. Each time the input processing unit 2 receives the input column position a and the input column number from the data transfer path 8 for each input record, it transfers the contents of the specified position in the input buffer through the data transfer path 0. It is sent to the output processing section 5. The output processing unit 5 stuffs the data contents sent through the data transfer path 10 into the output buffer while delimiting them with the delimiter information C sent through the data transfer path 12. When no data is sent through the data transfer path 10, the contents of the output buffer 7 are written to an output file through the data transfer path 11.

〔Effect of the invention〕

The file conversion method of the present invention has the effect of making it unnecessary to create a program for each specific conversion example by storing file conversion format information in a conversion table.
