This means that COBOL as a language now, has full access to the.net Framework classes and functions in the same way as other languages.

As COBOL is migrated to the.net environment, COBOL applications build to intermediate language code in the same way as other Microsoft.NET languages. These services will be accessed either directly from languages such as Microsoft C#, Microsoft Visual Basic.NET or from extended COBOL code. In essence, with this approach the traditional business processes encapsulated in the COBOL business logic are exposed as services. Where such an interface can be defined, it is possible to continue to reuse the existing procedural business logic and access it from other applications in the enterprise either through Web services, or by modernizing the user interface through which the application functionality is accessed. When extending an application, it is necessary to provide a means (or interface) to access the business functions that are to be extended. The ease with which an application can be extended will, in part, depend on the structure and nature of the existing application itself.

However, when migrating existing code into the.net Framework, it is often with a view to extending the use of the application. A large percentage of this code can be reused in the.net Framework migrating, providing existing application functionality as managed code. Most existing applications contain a large volume of traditional COBOL business logic combined with SQL or VSAM/ISAM data access code.

COBOL applications can now be developed with Microsoft Visual Studio 2005 for deployment into the.net Framework, existing procedural COBOL code can be reused, while Micro Focus and Visual Studio tooling can be used to extend such applications, exposing COBOL business processes as Web services or adding a.net Windows Form or WebForm interface to an existing COBOL application. In this paper, we will discuss how Micro Focus helps to extend and modernize COBOL applications reusing existing code within the Microsoft.NET architecture.

1 Such business needs translate into challenges for IT managers and architects such as how to extend the reach of existing applications to new users through the web, how to integrate COBOL applications with other applications across the enterprise, and how to provide a productive development environment to motivate and retain COBOL programmers. They want to: 1) reduce cost, but not at the expense of value, 2) reach more customers, 3) offer more flexible channels through which their services can be delivered, and 4) reduce complexity within the organization. IT leaders have many concerns and businesses have a short list of imperatives.

This provides a variety of options for enhancing and extending existing systems. 1 Introducing Micro Focus Net Express to Develop and Extend COBOL Applications White PaperДў Abstract This paper will introduce the capabilities of Micro Focus Net Express that allows COBOL to operate within the.net environment.
