DATA EXCHANGE APPARATUS AND METHODS

Apparatus and methods for the exchange of data between files having different types. The apparatus includes means for reading a logical record from a source file and using the data contained therein in the production of a generic form in which data is represented as an arrangement of displayable characters and means for using the data represented in the generic form to produce a logical record for a destination file. The means for producing the generic form may further include means for inserting a user-defined code in the generic form to mark fields of the source file logical record. The means for producing the destination file logical record may then employ the user-defined code to produce corresponding fields in the destination file logical record. The apparatus may further include data viewing means which permits the user to view the generic form and interactively define fields therein. The means for producing the destination file logical record may then employ the field definition for the generic form to produce corresponding fields in the destination file logical record.
