This document covers the following topics:


Natural for Ajax

Using the new product Natural for Ajax, you can create rich internet applications which use the Ajax (Asynchronous JavaScript and XML) technology. These rich internet applications use the Natural Web I/O Interface. This interface is available on UNIX and mainframe platforms only. The language extensions which have been made for this purpose (such as the new statement PROCESS PAGE) are listed in the remainder of these Release Notes.

A new example library, SYSEXNJX, is available for Natural for Ajax.

For detailed information on the installation and usage of Natural for Ajax, see the new Natural for Ajax documentation.
