This document covers the following topics:
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.
The new object type "adapter" is provided in this version. It is used to represent a rich GUI page in a Natural application. For further information on this object type, see Processing a Rich GUI Page - Adapter in the Programming Guide.
Natural (system commands, utilities, etc.) has been enhanced in order to support this new object type.
Note:
The EDIT command is not currently
supported for this new object type. A specific editor for objects of type
"adapter" is planned for a future version.
The following new Natural statement is provided in this version:
| Statement | Description |
