The Yoix scripting language is ideal for building web applications. Implemented using Java² technology, the Yoix interpreter runs wherever Java runs. The Yoix language includes many features and constructs from both the Java and C languages. Because it uses Java technology, it is cross-platform, GUI-capable and both network and thread friendly, yet requires less coding than using Java directly. The interpreter can use URLs to access Yoix scripts via a web server. CGI interactions are equally simple. Though socket level communication methods are also available, robust and scaleable web applications can be constructed using straightforward, familiar client interactions with a web server. Such a model is being successfully used by AT&T for one of its fraud management systems, which is utilized 24/7 by hundreds of users at diverse locations. This paper briefly describes the Yoix language and focuses on its use as a tool for building web-based systems.
