This companion to "e-RPG: Building AS/400 Web Applications with RPG" includes new techniques and functions to make e-RPG programming easier and more powerful than ever before. Not only does it provide the knowledge needed to create fully functional Web applications using OS/400 and RPG, but it also offers a thorough introduction to the Integrated Language Environment (ILE). Operators learn about using embedded SQL for easier and more effective queries, using e-RPG as Perl for OS/400, debugging information for e-RPG and JavaScript, and creating dynamic Web page changes. Users are also introduced to XML and handheld device programming through Wireless Markup Language (WML) and Handheld Device Markup Language (HDML) examples.
