These sessions relate to RPG IV and ILE.
If you were to write a new application in RPG, what would it look like? Or, what, potentially, would a modernized RPG application look like?
In this session, Paul takes you through the design and implementation of a modern RPG application - with lots and lots of code examples. Topics covered include...
One of the key questions is - how easy is it to integrate Watson into my existing RPG applications?
In this session we look at some of the way that RPG can connect with Watson (using the translation API) - and just how simple it is.
As well as looking at different methodologies, we will also discuss the advantages, and disadvantages, of the different approaches.
In this session, Paul discusses the what and why of standards and guidelines for modern RPG development. Topics include:-
This session covers tricks and techniques for the RPG IV programmer.
Come to this session and learn some of the things that you may not have known about...
Many RPG programmers have used interactive SQL as a tool to quickly browse data or to create test data scenarios, but have stopped short of embedding it into their RPG programs. Come to this session to learn why, when and how you may want to use SQL in conjunction with RPG. We will cover the basics of embedding SQL into RPG, including using SQL cursors, and a few tips on getting good performance from your SQL applications.
This session looks at:-
You have been using embedded SQL in RPG. You have mastered the syntax, tried a few selects, declared a cursor, performed an update - you may even have tried some dynamic SQL!
Time to take it to the next stage and see what you can do with embedded SQL - beyond the basics
Topics covered in this session include:-
In this session, Paul offers a practical guide to handling some of the more esoteric problems in RPG programs (whether using native I/O and Embedded SQL) such as...
What are pointers? What are User Spaces? What can you do with them? This session guides the programmer through the implementation of pointers in RPG IV, how they extend the capabilities of the language, their importance in an ILE environment and how they are used with APIs - especially those dealing with User Spaces!
By the end of this session, attendees will be able to:
Learn all about the various options for error handling in RPG IV.
This session explains:
Commitment control has always been available on the system but is very rarely used. But that doesn't mean that you shouldn't be using it.
Commitment control is an application decision as opposed to a programming decision. As companies look at modernizing their applications commitment control is a feature they should be considering.
This session looks at:-
There is a LOT> that you can declare in RPG! And there is a lot of versatility in the way you can define it!
A myriad of declaritave keywords can cut down on your coding requirements
This session looks at permutation and combination of declaring...
Multiple examples of definitions (and how they are used) are provided
This session takes a small sample RPG IV application and examines the issues involved in integrating it into an ILE application.
This includes decisions on Dynamic Binding, Static Binding, Bind by Copy or Reference, structure of Service Programs, Binder Language, Binding Directories and Activation Groups.
By the end of this session, attendees will be able to:
Although it is very rare that the implementation of any two ILE projects are exactly the same, there are a lot of ground rules that are required in all implementations.
This session discusses some of the considerations for a successful ILE implementation including how to control and manage the development environment, development tools to use, design considerations (Activation Groups, Binding Directories, using Service Programs) and documenting procedures.
Prerequisite: Attendees must have a basic understanding of the components of ILE.
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.
System APIs can be challenging and, at some stage, nearly every programmer is confronted with using them. But once you get to grips with interpreting the documentation, you will find that the system APIs offer a host of opportunities
This sessions explains how to get to grips with System APIs and expand the possibilities of what the system has to offer your applications.
Topics include:-
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:-
How is it possible for an RPG program to be called from a web browser? How can an RPG program output to a web page? What is a HTTP server? What is CGI? This session explains how it works with easy to understand examples.
In this session, learn:
