RPG-Oriented Sessions

Advanced Data Structures ( *Now with Free-Form! )

Have you ever used two dimensional arrays in your RPG programs? Or used the new template support to create your own data types? Do you know how to use group fields? How to map the *IN indicators so that you can give them names? Do you know how to code these in the new free-form style?

If you answered "No" to any or all of these questions then this is the session for you

We'll give you a basic introduction to all of these topics and show you practical examples of their usage. We'll also include examples of the latest enhancement for coding nested Data Structures that makes their structure much more obvious.

P.S. We should also mention that some of the basic techniques discussed here are the technical underpinnings needed to fully utilize RPG's support for processing XML and for Open Access. So if you see XML or Open Access in your future you might want to check this session out.

Speaker: Jon Paris

Development Strategies on Power

In this session, Paul Tuohy discusses the key factors in determining development strategies on Power systems.

The challenges facing companies, as they progress through different levels of modernisation, are many. How does a company change from a traditional development and maintenance environment to a more robust, modern development environment? What is new, what is different, what are the major and minor obstacles.

Paul also discusses the challenges faced by developer and what makes a modern developer on Power systems.

Speaker: Paul Tuohy

21st-Century CL

IBM i Control Language (CL) has long been used as a language for both operations and job control. In the most recent releases of IBM i (V5R3 thru 7.2) IBM has delivered many long hoped for and long requested enhancements to CL for both environments.

Enhancements include new commands as well as new extensions to existing commands. What are these new features and functions? How can they be used? What's the very latest that CL has to offer? This session will answer those questions and more

Speaker: Ted Holt

SQL Procedure Language for RPGers

The SQL Procedures Language is a database-oriented programming language that offers several benefits to IBM i professionals.

  • It provides an easy and powerful interface to the database.
  • SQL PL can be sued to build functions, triggers, stored procedures, and dynamic compound statements.
  • It runs on all DB2 platforms, not just DB2 for i.
  • SQL PL implements SQL Persistent Stored Modules, an ISO standard, and is similar to scripting languages used on non-IBM platforms.
  • Programmers who know RPG, CL, or COBOL will find SQL PL easy to learn. In this session, Ted Holt presents an overview of the SQL Procedures Language. Topics covered include basic syntax, control structures, and condition handling.

    Speaker: Ted Holt

    RDi: Even Better with iSphere

    It's no secret that Susan is a big RDi fan. But even a great tool can be made even better with the help of plug-ins. If you're an RDi user and you don't have the iSphere plug-in installed into your RDi, you're missing out on a wealth of new/enhanced functionality.

    Susan will demonstrate a few of her favorite features from iSphere - things such as a better "Find String" capability, tools to make working with message files a breeze and the ability to see text for objects and members in your Remote Systems lists. She will also outline the simple installation process along with some suggestions for how to manage updating iSphere when new releases become available.

    Speaker: Susan Gantner

    Git 101: Understanding Git

    Git - a version control system popular for Open Source languages - is getting a lot of attention and gaining favor with many RPGers as well. Come to this session to see what all the buzz is about.

    The companion session: "Git 102: Migrating to git for RPG Apps" will describe how you can use git for your RPG application development.

    Speaker: Stephanie Rabbani

    Test Driven Development - Best Practices using Automated Tools

    Current best practice for producing high quality software is Test-Driven Development. These practices can be applied to RPG development on IBM i.

    The end result is software where every single line is covered by an automated test and can easily be regression tested on every build of your deliverable.

    Tools such as RPGUnit and RDi can be used to support this process and make it easier and more enjoyable.

    Learning Objectives:

    1. Learn the best practice of Test Driven Development
    2. Be able to articulate the benefits of this approach
    3. See a practical example in the context of ILE RPG and the IBM i
    4. See how the open source packages like RPG Unit can help
    5. Learn how Rational Developer for i can be used to support this process

    Speaker: Barbara Morris

    Business Uses of Python

    Does Python on IBM i have a practical use or is this just a solution looking for a problem? In this session we will explore the typical use cases for Python in the open source community and apply some to IBM i. In addition, specific IBM i centric use cases will be explored to give the attendee the opportunity to judge for themselves how to best leverage Python in the combined open source and IBM i space.

    Learning Objectives:

    1. Learn how Python is used in Open Source environments.
    2. Explore how Python can be exploited in IBM i centric environments
    3. See several examples of open source Python applications in action on I

    Speaker: Mike Pavlak

    A Nerd's Guide to DATA-INTO in RPG

    DATA-INTO has the same power and ease of use that RPGers have enjoyed with XML-INTO for years. Unlike XML-INTO, however, DATA-INTO is not limited to XML documents! With DATA-INTO, RPGers can read JSON documents, as well as other structured documents like CSV, or just about any format you can imagine.

    This session discusses the basics of DATA-INTO, and how it makes it easy to process structured documents in RPG. Then, it explains the basics of adding support for your own structured documents by writing your own parser.

    Speaker: Scott Klement

    Impress Your Boss with Open Source

    Open source brings ready-made solutions that can run on your IBM i, usually at no charge. Create graphics, PDFs, content management for the web, not to mention web languages that allow you to address new business needs. What's more, these open source technologies work well with RPG.

    In this business-oriented talk, learn how companies are staying ahead of the curve with open source on their IBM i. See how RPG provides the solid business logic to provide business advantage, while open source brings interfaces and capabilities up to date. Be prepared to be wowed by many examples.

    Speaker: Alan Seiden

    Configuring RDi for RPG Development

    RDi is the most versatile application development tools available today. It provides more and more functionality with each update, and the results are obvious. This session focuses on the particular

    Speaker: Charles Guarino

    Processing XML with RPG

    In this session we'll look at RPG's native support for XML processing, including the latest enhancements. We'll also include a brief overview of the Data Structure features added in V5R2 that are critical to understanding how the XML support works.

    Whether you are using XML for web services or data interchange, dealing with XML in RPG can be challenging. V5R4 brought welcome relief in the form of new RPG language support that greatly simplified parsing XML within your programs. While useful, there were issues that IBM subsequently addressed in enhancements released in V6 and 7. The result is a powerful set of XML processing capabilities that are also easy to use once the basics are grasped.

    Speaker: Jon Paris

    Providing RPG Web Services on IBM i

    In this session, you'll learn how to provide web services using the tools that are included with IBM i. Scott will show you how to configure the HTTP servers so that they will call RPG programs, and how to write RPG code that acts as a web service. Both SOAP and REST web services will be covered.

    Speaker: Scott Klement

    Introduction to XML Basics and Generating XML with RPG

    Every day more and more RPG shops are finding that XML is playing an increasing role in their data interchange operations. In this session we will introduce you to the basics of XML syntax and show how it compares with HTML and DDS.

    Having dealt with the basics we then move on to discuss several ways in which XML can be generated from RPG programs. While there is no direct support for XML generation in RPG, the good news is that there are a number of tools available that can be used to help you. The even better news is that all of the tools we will introduce you to are available free of charge.

    Speaker: Jon Paris

    SQL Aggregation without Aggravation

    SQL provides powerful ways to retrieve detailed data and format it the way users need to see it. SQL can summarize data, giving users the information they need to make informed decisions. But what do you do if the user asks for both detailed and summary information in the same query?

    You attend this session.

    Ted Holt has successfully dealt with this struggle. In this presentation, he shares techniques you can use to combine details and summaries to satisfy the needs of those whose jobs depend on your system.

    Topics include:

    1. The necessity of UNION ALL
    2. Extensions to GROUP BY
    3. How to "roll" totals by hand and when you should do so
    4. How to count. (Yes, you read that correctly.)

      Discusses what a Web Service is and how the free HTTPAPI tool can be used to consume them from your RPG programs. For example, you could use a Web Service to track shipments with UPS, check Zip Codes with the US Postal Service, validate credit cards with your bank, etc.

      Speaker: Scott Klement

      Embedded SQL in RPG - Beyond the Basics

      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:-

      • Discussion of the key points in writing powerful embedded SQL

      Speaker: Paul Tuohy

      RPG Open Access - By Example

      This session introduces you to the fundamentals of RPG 's Open Access (OA) by taking you through the process of designing two simple Open Access handlers that present different challenges.

      OA provides a mechanism that allows you to simplify how an RPG program interacts with interfaces that the RPG language does not natively support. For example things such as web services, the IFS, data queues, spreadsheets, browsers and more. By using a suitably designed OA handler, your programmers can access such interfaces through native RPG I/O operations (such as READ, WRITE, CHAIN, UPDATE, etc.). They don't have to understand the underlying mechanics, they can simply use their existing RPG skills.

      In this session we will start by introducing you to a template that forms the foundation for all the OA handlers that we write. Next we will look at how choosing an appropriate architecture can simplify the design of the OA handler and ensure that using it "feels like RPG".

      Speaker: Jon Paris

      Working with JSON in RPG Using Open Source Tools

      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 or generate JSON in an efficient manner.

      Speaker: Scott Klement

      Handling the Weird Stuff in RPG Programs

      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

      • Messaging in a multi client environment
      • Trigger Failures
      • Nulls
      • Constraint Violations
      • Commitment Control
      • And other bits and pieces...

      Speaker: Paul Tuohy

      Extending RPG with Db2 for i Functions

      This session explores the wealth of non-database capabilities that SQL can do for you within your RPG programs. These range from the use of simple SQL scalar functions within your RPG (e.g., for upper/lower translations or math functions) to grabbing IFS text to executing web services - and making sense of the XML or JSON data that often comes back from them.

      Learn to exploit the power of basic SQL functions, user-defined functions (UDFs) and some of the Db2 for i Services from your RPG code. It's easier than you think!

      Speaker: Liam Allan

      The World of Node.js on IBM i

      Node.js is just getting started, but it is very hot! Everyone seems interested in getting started with this language today, and it may very well represent the future of Application Development on IBM i. In this session, we'll look at Node.js, discuss how it works and how to write simple applications. Then, we'll take a look at the Node Package Manager (npm) and the power it brings to the Node.js environment.

      The session will cover:

      • A high level introduction to the concept of Node.js on IBM i
      • The basics of a Node.js application, with links to where you can learn more
      • How to get started with the Node Package Manager (npm) and why it's exciting to have on IBM i
      • How to use NPM in your own applications.

      Speaker: Scott Klement

      RPG Free Form in a Nutshell

      Expressions and limited free-form calculations have been part of our RPG IV coding lives since the inception of the language. Most of us wholeheartedly took the next step when V5.1 introduced completely free-form logic. Then came V7.1 and with it RPG IV gained the ability for programs to be coded completely in free-format.

      Perhaps you've heard about this feature, you may even have read an article or two, or even tried your hand at writing some free-form code. But many RPGers have stumbled over "how do I ... ?" issues and wonder if it is really worth the effort. If you're in that group then come to this session and in a mere 45 minutes Jon will do his best to clear up any misconceptions you may have and show you why and how to take this next step.

      In this session, Jon will explain:

      • Why free format RPG is important
      • What are the rules
      • Just how free can you go?
      • Are there any likely gotchas?
      • Are there tools available to convert fixed format code easily?

      The session will include a brief refresher on free format logic, but will focus primarily on the new free-form declarations (i.e. the replacements for H, F, D and P specs) as well as the ability to use as many columns for your RPG logic as you need - starting in column 1 if you want!

      Speaker: Jon Paris

      Understanding & Using Delicious Yum for Open Source

      Sorry! The full session description for this session is still being developed.

      This session will be about understanding, installing and using Yum - the latest way to install open source software on IBM i. This will describe the version of Yum that is unique to IBM i.

      Check back later for a more complete description.

      Speaker: Liam Allan

      ILE Activation Groups

      In this session, Susan tackles the tough topic of Activation Groups - what they are, what they can do for you and what they can sometimes do to you! She'll provide some tips to help make their impact on your applications a positive one - including the concept of scoping and some default parameter values you should probably avoid.

      At the end, there's a simplified "cookbook" of what parameters you should use if your goal is to have your ILE applications function as closely as possible to what your non-ILE versions of those applications did. But hopefully by then you will also understand some of the reasons for the suggestions in the cookbook.

      Speaker: Susan Gantner

      Refactoring RPG: What, Why and How

      Refactoring is rewriting source code in such a way that the new code behaves as the current code does, but is easier to read, understand, modify, enhance and debug. Refactored code takes advantage of features that were not available, or were ignored, when the code was written.

      This presentation, which is geared toward the RPG programmer, is given by Ted Holt, who has been writing RPG programs since 1982 and has programmed in RPG II and every version since then. Ted explains what refactoring is and is not, why you should refactor, when you should not refactor, and how to refactor RPG. If you have old RPG code in your shop (and who doesn't?), this presentation is for you.

      Speaker: Ted Holt

      This session covers Barbara's take on:

      • The features of ILE RPG that allow you to write "modern" code
      • Which old features to avoid
      • How using service programs can modernize your development, both new function and maintenance

      Speaker: Barbara Morris

      RDi and Git - The Easy Way

      What are the steps to getting your source code stored in a Git repository, be it on IBM i or externally, such as on GitHub? We will go through the entire process step by step and get you on your way. Attend this session and you will see how to implement RDi and Git - The Easy Way!

      Speaker: Charles Guarino

      Building Reusable APIs

      When should I use an API? What are the benefits of writing APIs? This talk will cover when to use Web APIs to access your data, as well as some tips on how to write a Web API that is flexible and designed to last.

      Using code examples in RPG, PHP, and Python, Steph will also share lessons recently learned from working on a large integration project with Salesforce.

      Speaker: Stephanie Rabbani

      Debugging with RDi

      Into each programmer's life, a some bugs must fall. In this session, Susan will cover how to use the debugger that's built into RDi - Rational Developer for i.

      If you've tried using the debugger that's integrated with the RSE tool for editing code and struggled with making it work, you may find that 3 little words can make all the difference: Service Entry Points. Come here to see how to use SEPs when debugging your programs. We'll also cover how (and why) to create and use debug configurations for those occasions when SEPs may not be the best choice.

      Speaker: Susan Gantner

      This session intentionally left blank

      Due to travel schedules etc. attendance at the last session of the conference is always lower. So in order to help the final sessions gain the audience they deserve we've made the decision to only run three sessions in the final slot.
