There are ways to turn green-screen applications into more current and useful web-based applications, or allow for sharing with other applications. These methods offer value by building on the logic embedded in green-screen applications, rather than requiring source-code changes or screen-scraping.

Modernization approaches that use the application logic can be vastly more powerful, efficient, and easier to maintain than screen-scrapers. This paper is intended to debunk some common myths about modernization technologies, and demonstrate what advanced modernization strategies can enable you to do compared with more traditional approaches.
