This tutorial guides you through using the Data File Editor and the Structure File Editor to create new data and structure files, and to view and update existing data files.
The demonstration application used in this tutorial consists of a data file and the COBOL source program that maintains it. The data file is a variable length sequential file, containing details of staff in three record types: employee, manager and executive. In this tutorial, you will: view the file formatted and unformatted; update records and apply layouts to them; and create and edit a new file.
