The Interface Mapper is the tool that enables you to define your service interfaces. You can define a service interface for a COBOL application from the COBOL source code. The service interfaces you define can cover a broad range – from those that provide access to a subset of the functions performed by your application, to interfaces that do more than your application in its original form. This is done by associating, or "mapping", the fields in your legacy application to the fields you create in the service interface.
The following topics describe the Interface Mapper and the operations you define with it.
