The Data File Tools enable you to create record layout and segment layout files using Open PL/I structures. The Data File Editor and IMS Database Editor use these layout files to present records or segments a a formatted data item view that enables easier editing.
When you compile a PL/I program for debug, Enterprise Developer creates an output file containing the PL/I structures that are required as input for the Record Layout Editor and the Segment Layout Editor Data File Tools, which use the information to map PL/I data item types to the COBOL data item types used by the Data File Editor and IMS Database Editor Data File Tools. The output file is added to your Enterprise Developer project, and has a .adt file extension.
