Abstract

In a data processing or word processing application, it is often desirable to duplicate files for archival or backup purposes. In the duplicate file task, however, it is possible to have a source file with one field being longer than the maximum length of the corresponding field in the destination file. When duplicating files, records which have a field longer than the maximum length of the corresponding field in the destination file cannot be copied. It is therefore necessary to inform the user which record is not copied. A solution to this problem is to put the records that cannot be copied into an error file. The error file has the same format as the source file. The operator can display or print the error file after the completion of the duplicate file task.

Duplicate Error File Generation for Illegal Records

In a data processing or word processing application, it is often desirable to duplicate files for archival or backup purposes. In the duplicate file task, however, it is possible to have a source file with one field being longer than the maximum length of the corresponding field in the destination file. When duplicating files, records which have a field longer than the maximum length of the corresponding field in the destination file cannot be copied. It is therefore necessary to inform the user which record is not copied. A solution to this problem is to put the records that cannot be copied into an error file. The error file has the same format as the source file. The operator can display or print the error file after the completion of the duplicate file task. The operator then has the choice of modifying the error file or updating the maximum length of the destination file. If the operator chooses to update the maximum length of the destination file, the operator can then try to duplicate the error file into the destination file again. In many cases because of constraints of forms and other requirements, the operator's choice will be to modify the error file rather than update the maximum length of the destination file. Once the error file has been modified, the operator can again try to duplicate the file into the destination file.
