Abstract: A file update processing apparatus which enables execution of an intended file processing in accordance with the description contents of a correspondence slip and a generation table without requesting a system engineer to design a file processing program when a general person in charge who understands specific items required for a file in execution of daily operations sets predetermined items in the correspondence slip and the generation table so as to match his own business contents. When an original book registration slip, a journalizing table, and an expansion table are input from an input unit, an input processor registers them in correspondence with data files. A file processor generates a record on the basis of items set in the original book registration slip and items generated on the basis of the generation tables and updates the data file on the basis of this record.

Abstract: Partial forms constituting parts of a slip or the like are stored in a printing apparatus side. A partial form corresponding to the type of data output from a computer is read out, and the data is overlaid with the partial form to be printed. One slip is formed by combining a plurality of partial forms. Therefore, a slip can be formed in accordance with the number and type of data, and data can be properly fitted in a form and printed. A large variety of types of forms can be printed in accordance with the type or the like of data to be printed.

Abstract: All the combinations of upper-level parent parts and lower-level child parts constituting parent-to-child relationships in the structure of the parts are registered in a predetermined file in advance. When an arbitrary upper-level parent part is designated, all the child parts which are associated with the parent part are extracted by referring to the file. It is then determined whether a combination of parts including each extracted part as a parent part is present or not. If it is present, the referring operation is repeated again by setting each extracted child part as a parent part. When it is determined that a combination is not present, a corresponding child part is output.
