PURPOSE:To quickly perform the read-in processing of a source file by referring to a multi-byte code existence identifier to discriminate the presence/absence of character data of a multi-byte code in each text record at the time of the read-in processing of the source file. CONSTITUTION:Text records 10 each of which has a multi-byte code existence identifier 11 where data, which indicates whether the text record includes character data of a multi-byte code or not, is recorded are stored in a source file 1 and if the text record 10 stored in the source file 1 includes character data of the multi-byte code, a source file output means 2 records this inclusion in the multi-byte code existence identifier 11 and outputs the text record 10 to the source file 1. If the multi-byte code existence identifier 11 indicates that character data of the multi-byte code does not exist in the text record 10, a source file reading-in means 3 reads in the text record 10 from the source file 1 without discriminating whether data of one byte in the text record is a constituting element of character data of multi-byte code or not.
