Data processing apparatus for extracting and processing arbitrary records from a file

摘要

Disclosed is a data processing apparatus by which, when an output level is designated and code conditions indicating target items at the time of extracting an output record are designated in the desired order in association with a plurality of items to obtain a desired slip, records that match with a plurality of code conditions are read from a predetermined file and are output in the designated order in association with the output level. Therefore, records that match with a plurality of code conditions will be grouped into a hierarchical structure as specified by simply designating code conditions indicating the target items in association with a plurality of items at the time of extracting the output level and output records.
