Client and Server Examples for z/VSE Batch

This document describes the examples provided for the COBOL Wrapper for z/VSE Batch. All examples here can be found in the EntireX directory examples/RPC under UNIX and Windows. Alternatively, you can download the full set of z/VSE COBOL examples from Software AG's customer service site Empower. In Empower, choose Products > Download Components. The examples are provided as AWS tape EXAMPLE.AWS. The tape contains source code and the corresponding objects and phases, ready to run. This document covers the following topics:
