What's new in RPG for 7.4

Find out about what's new in 7.4 for RPG including several items that were already available through PTFs for earlier releases:

  • The most exciting enhancement is variable-dimension arrays, including a type of array that automatically grows as you assign new element
Other enhancements:
  • DIM(*CTDATA) let's you soft-code the dimension of an array with compile-time data
  • The SAMEPOS ikeyword lets you define an array over repeating subfields in an externally-described data structure
  • Two new subfields for the PSDS
  • DATA-INTO opcode - similar to XML-INTO, except that it works with any type of structured data, including JSON
  • ON-EXIT opcode makes it easy to reliably clean-up when your procedure ends
  • And more

Speaker: Barbara Morris

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 and later) 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

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

RPG Free Form in a Nutshell

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 this sounds like you then come to this session and 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 attempt to answer questions such as:

  • Why is free format RPG 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: Susan Gantner

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: "Migrating to git for RPG Apps" will describe how you can use git for your RPG application development.

Speaker: Stephanie Rabbani

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

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

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

Configuring RDi for RPG Development

In this session Jon will discuss modern data structure coding techniques, including the 7.4 support for dynamic arrays. He will also address one of the most common questions that he receives ... "How do I code the data structures needed for XML-INTO/DATA-INTO to process this document."

Other topics to be covered include:

  • Nested Data Structures
  • Data Structure I/O
  • Data Structure arrays
  • Benefits of qualified data names

Speaker: Jon Paris

RPG's XML-INTO, DATA-INTO & DATA-GEN Family of Operations

Today's RPG can greatly simplify dealing with non-traditional data - such as XML, JSON, CSV or any other format that may appear in the future. XML-INTO and DATA-INTO allow RPG programs to parse formatted data and populate RPG data structures with the contents. Need to generate formatted data from RPG data structures? DATA-GEN accomplishes that.

Come to this session to learn more about the data transformation potential of this family of operations to simplify data interchange.

Speaker: Barbara Morris

    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

    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
    • What tools should you use to write and test SQL prior to embedding it?
    • Controlling CRTSQLRPGI
    • SQLCA and SQLCODE considerations
    • Getting data without SELECT - GET DIAGNOSTICS and VALUES INTO
    • Talking to Watson with Embedded SQL
    • Accessing SQL Functions

    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

    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 used 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

    Calling Watson's AI APIs from RPG

    We're always hearing about the amazing things that you can do with Watson, but did you know that it's available to anyone to use? In fact, you can incorporate Watson's technology directly into your RPG programs.

    This session takes a look at some of the various Watson APIs that are available as well as how to call those APIs, which are implemented as web services, from an RPG program.

    Note: To get the most out of this session, attendees should first attend the session "Consuming Web Services from RPG with HTTPAPI" unless they already have knowledge of the basics of consuming web services from RPG.

    Speaker: Scott Klement

    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

    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.

    Speaker: Liam Allan

    (C D I R)? Introduction to Error Trapping and Recovery

    How many times have you received a phone call AFTER a well-intentioned user responds to an error message? “Don’t worry, I pressed ENTER, a “C” appeared and the error went away.” NOOOO! Take charge and eliminate this frustration! It’s YOUR job to make sure your users learn that “C” is for Cookie, not Continue! From trapping runtime errors to controlling job logs, it is your responsibility as the developer to have an error trapping system in place.

    In this session we’ll cover several techniques to put error management back where it belongs - in the developer’s hands. Learn how to empower your programs to anticipate, positively react and respond to error messages. In addition, there is a lot of job information available about your running programs when an error occurs. Why risk not being about to retrieve and analyze it to eradicate these situations before they occur again in the future?

    Speaker: Charles Guarino

    Creating Web Services With IBM's IWS

    "We need to supply a web service! Can you build one?"

    If you face this question there's no need to panic. Every IBM i comes with tooling that can make it easy for you to get started in building web services with nothing more than your knowledge of RPG and the help of the wizards in IBM's Integrated Web Services Server (IWS).

    In this session, Jon will introduce you to the basics of constructing and deploying REST web services with IWS. He will also introduce you to the latest support that allows you to simply deploy an SQL statement as a web service.

    In addition to creating web services Jon will also discuss how to test your new creations,

    Speaker: Jon Paris

    RPG Does Dropbox and Texting

    Did you know that RPG programs can interact with the Dropbox cloud document sharing site? Come to this session to hear how this marriage of RPG and Dropbox and a bit of text messaging solved a document sharing requirement better and easier than FTP.

    In this session, to see how to share files between IBM i and Dropbox. We'll explore both how to upload documents from IBM i to Dropbox and how to download documents from Dropbox to IBM i using RPG and SQL. You'll also see why this approach worked better for this application than traditional approach using FTP to the IFS.

    Finally, we'll see how to send text messages from IBM i using RPG and CL. You'll learn how to send a plain text message indicating that a file has been uploaded or downloaded from Dropbox and how we can even include the actual document in the text message.

    Speaker: Charles Guarino & Mike Larsen

    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.
