M-Business Anywhere Web Edition Pro combines all of the features of Web Edition Standard, plus support for JavaScript and the M-Business client extension API. JavaScript adds the ability to provide a more interactive experience on a page by adding business or navigation logic to pages and forms, creating robust, two-way Web applications. The M-Business client extension API allows you to write C code that integrates closely with the M-Business Client binaries, with the ability to access any hardware features that are software-controllable. Most of the M-Business client extension API is also accessible from JavaScript.
