S67: The character string comparing section 24 determines whether or not the number of blanks in the survey file is the same as the number of answers extracted in the result file. If it is determined that the number of blanks and the number of answers in the survey file are the same (YES), the process proceeds to step S69, and if they are different (NO), the process proceeds to step S68.

S68: The character string comparison unit 24 adds (appends) a message indicating that the extraction has failed to the end of the result storage file stored in the storage device control unit 23, and at the same time, sends the message from the output control unit 22 to the display 5 And the process proceeds to the processing S69.

S69: The storage control unit 23 receives the comparison end notification from the character string comparison unit 24, and the storage control unit 2
3 clears the saved result storage file name and transmits an end notification to the input control unit 21. Thus, the input control unit 21 prepares to receive the next file name to be compared, and transmits an end notification to the output control unit 22. The output control unit 22 displays on the screen of the display 5 a message prompting the user to input the survey file, the answer file, and the result storage file name from the keyboard 3 and performs processing S
Return to 61.

In all of the cases (1) to (7), the character string comparing section 24 can extract the characters entered in the answer column of the answer file. This makes it possible to extract characters written in the answer column more reliably.

The number of characters to be compared before and after the answer column of the answer file and the survey file can be up to the first character of the column and up to the line feed code after the answer column. It is appropriate to use 5 to 6 characters in consideration of efficiency.

[0105]

As described above, according to the present invention, the following effects can be obtained. Characters entered in the entry (answer) column of a text file handled by the information processing device can be automatically extracted.

Even when the answer entry field of the answer file is enlarged, characters entered in the answer entry field can be extracted. Even if characters before and after the answer column in the answer file are missing, the characters entered in the answer column can be extracted.

Even if there are extra characters before and after the answer column in the answer file, the characters entered in the answer column can be extracted. Even when the two-byte and one-byte relationships do not match in the survey file and the answer file, the character string entered in the answer column can be extracted.

Even if the character code in the survey file is different from the character code in the answer file, the character example entered in the answer column can be extracted. If the number of answer columns in the survey file is different from the number of answers extracted from the answer file, this fact is displayed or stored to indicate an extraction error to the user.
