Net.Data Language Environment Guide

Creating a New Language Environment

Before you decide to create a new language environment, determine if the IBM-supplied language environments that are shipped with Net.Data satisfy your needs. If you decide to create a new language environment, then you must complete the following two steps:

1. Build a DLL or shared library that implements the set of language environment interface routines you want to provide. The dtw_execute() interface must be provided, and all interfaces provided must match exactly the prototypes defined in the dtwle.h C language header.

   Also, all interfaces must be made externally available from the DLL or shared library so Net.Data can call them.

2. Determine your ENVIRONMENT configuration statement, then add it to the Net.Data initialization file. See "Configuring a Language Environment" for details.

Adding an ENVIRONMENT configuration statement to the initialization file is a simple matter of editing. However, the first step, building a DLL or shared library, is more complex.
