The EntireX documentation contains the following Natural-related topics:
Common integration scenarios: Calling your Natural server subprograms from the Integration Server Adapter Service or a Web
service client; calling an Integration Server Service or a Web service from a Natural application. 
More info
The Natural Wrapper allows you to develop Natural client applications that access
RPC-based server components, and to create Natural RPC server skeletons you can use as a basis
to write a Natural RPC server that can be accessed by RPC clients. More info
The Software AG IDL Extractor for Natural extracts a Software AG IDL definition
from a Natural source in a Natural project in Eclipse, or from an object
within a Natural RPC environment. More info
The EntireX Java Wrapper for Natural allows you to generate EntireX Java client
interface objects from Natural subprograms in a NaturalONE project in Eclipse.
The generated Java client interface objects can be used by Java application developers
to access Natural server components, using EntireX/Natural RPC. More info
The Adapter Services Wrapper for Natural enables webMethods Integration Server to call Natural subprograms.
The interface of the Natural subprograms is extracted and connections and adapter services are generated in
Integration Server. More info
The EntireX Web Services Wrapper for Natural allows you to develop Web Services that access Natural
server components, using EntireX/Natural RPC. More info
EntireX Broker ACI Programming from the perspective of progamming language Natural.
The ACI control block definition is located in file NATDEF of the supplied application (SYSETB). More info
The RPC-ACI Bridge enables RPC-based client applications to be used with ACI servers. See Writing RPC Clients for RPC-ACI Bridge in Natural and Writing ACI Servers for the RPC-ACI Bridge in Natural
