JSON (JavaScript Object Notation) is quickly becoming an important document format for business data interchange, so what's the best way to process it from RPG? JSON provides the same benefits as XML, but is smaller (and so transmits over a network more quickly) and is much more efficient than XML to work with in web applications. Naturally, this means that your RPG business applications need to learn how to speak JSON in order to talk to many of the newer web services or exchange data with many tech-savvy business partners. In this session, Scott will explain how the open source YAJL tool can be used from an RPG program to process JSON with the DATA-INTO opcode, directly with YAJL's API and generate JSON with YAJL.

Learning Objectives:


1. Basic introduction to JSON format
2. How to generate a JSON document in RPG with YAJL
3. How to read a JSON document in RPG with DATA-INTO
4. How to read a JSON document in RPG with the YAJL API
