Charlie presented the following sessions:

RPG! It's Alive with New TreasuresCharlie

“New” RPG Free Form enhancements? Well sure, but that happened at 7.1. Time marches on and so do the enhancements. Today’s RPG is living, vibrant and ever-evolving, keeping pace and meeting the requirements and needs of TODAY’S programming community.

If you haven’t been keeping up you are missing out on the many new treasures that will not only improved the readability of your code but also the reliability. Long live RPG!

Putting the Pedal to the Metal for RDi

Need a crash course on seeing if RDi is right for you (hint – it is) but can’t commit an entire day on a workshop? In this session we will cover the key points of Eclipse navigation, source code editing, program debugging and graphical screen and report design. Even after only one session you will see how a modern workbench is where you need to be using to stay in the game of application development.

The less frequent RDi FAQs - More stuff to know!

RDi is a game changer and continues to improve how developers are maintaining and developing their applications everywhere. And with the breadth of functionality there is almost never enough time to answer all of the questions at our sessions. Here we will go through some of the most challenging and obscure questions and provide live demonstration to answer them. Let’s learn together how RDi can further your productivity in ways you never thought possible.

XML and JSON REST Web Services for Everyday RPG and SQL Consumption

A web service extends your applications in a way that no traditional programming can. They allow you to get real time information for almost any requirement. We’ll discuss what web services are, how they function and how you can begin using them on your own system. Get step-by-step instructions on the entire Web service process from receiving an XML or JSON document to successfully parsing its information to a display or database file.

See working RPG code of an XML parsing program and watch how we consume a RESTful web service. Updates include i7.1 SQL enhancements which make consuming web services a snap. This session includes source code to get started using dynamic Web services today!

RPG on the Move: Mobilize Your i

Choices and challenges in the world of mobile applications

Mobile applications are the hot topic of the day and your old RPG green-screen skills and tools are just not going to make the grade. In this session Paul discusses some of the factors you have to consider when embarking on the development of your first mobile applications.

Topics to be covered include:

  • Design considerations for mobile - from F-keys to touch sensitivity
  • Platform options - iPad? iPhone? Android? Blackberry? Tablets?
  • Local processing or server/browser based?
  • Can you do it with RPG? And what are your other language choices

Introduction to AJAX for RPG Programmers

Although it has been around for a number of years Asynchronous JavaScript and XML (AJAX) has suddenly become a hot topic. What is all the fuss about? What relevance does AJAX have for the RPG programmer?

AJAX provides a means of having a web page communicate with a server, either synchronously or asynchronously. Combined with CGI programming techniques (CGIDEV2 is used in the presentation), you now have a means of dealing interactively with a web page i.e. changing the contents of a web page without having to re-write the whole page.

And best of all, it is already installed on every PC, all you have to do is use it!.

In this session you will learn:

  • The background to AJAX
  • How it works
  • Examples of how to use it

I Didn't Know You Could Do That With SQL

You have started to master SQL but you have a sneaky suspicion that there might be more to it.

In this session you will learn valuable and time saving techniques with SQL that let you avoid writing code. You will learn how to use SQL Subquery or Subselect in an SQL SELECT, INSERT, UPDATE, DELETE or CREATE TABLE statement to reference multiple tables without having to do a join of the tables involved. You will see how to use CASE and UNION statements, Common Table Expressions (CTEs) and where to use Full Outer Join and Hidden Time Stamp columns.

This session is based on the SQL function available in V5R4, V6R1, and V7R1 of OS/400 or i5/OS, assumes you have a basic understanding of relational database concepts and SQL.

Externalizing Database Processing in RPG IV

One of the major considerations for the ongoing modernization of applications is how to make functionality accessible to multiple interfaces. But no matter how the application interfaces may change (green screen, web, client server, mobile phones etc.) or how data may arrive on the system (FTP, EDI, XML etc.) you can be sure that all of the data is going to end up in a database.

Externalized database processing provides a means of encapsulating database access. This session discusses why you may want to externalize database processing in RPG IV and how to do it.
