Together with Studio Enterprise Edition for UNIX you receive a group of components called Server Enterprise Edition for UNIX. Its purpose is to provide a shell that sits on top of your operating system, providing the same environment on different operating systems. This enables you to port COBOL applications easily from one operating system to another.
Server Enterprise Edition provides additional facilities as described in earlier sections. The environment provided for COBOL by Server Enterprise Edition can be compared to that provided for Java by a Java application server.
