The public interface of a service program consists of the names of the exported procedures and data items that can be referenced by other ILE objects. In order to be exported from an ILE service program, a data item must be exported from one of the module objects making up the ILE service program.
The exports list is used to specify the public interface for a service program. A signature is generated from the procedure and data item names listed in the binder language. This signature can then be used to validate the interface to the service program.
As long as the public interface is unchanged, the clients of a service program do not have to be recompiled after a change to the service program.
