October 2021 Monthly Dinner Meeting 

This month we have Vern Hamberg driving in from Minnesota to deliver two great sessions.

Vern Hamberg Bio

Vern has worked on IBM midrange systems for over 30 years, beginning with the System/38 and AS/400.  At present he is a senior IT developer for the Pest Elimination division at Ecolab.  He is degreed in both music and mathematics, which gives him a distinct approach to the art and science of programming. In his spare time he plays in a communiy band and sings in a pretty-good a capella choral group.  In 2011 he wrote a special report on IBM Rational Open Acces: RPG Edition that was published in System i News in April of that year.  More recently he has become more involved in community musical theater as music director, vocal director, and accordionist.

Session 1: Leveraging the System-Using C Run-Time Function in RPG

Although RPG has an extensive set of operations and function that the developer can use, there are many function provided by the C/C++ run-time that can enhance what the developer can do with RPG and these are often very easy to use.

Learning Objectives

  • Learn how to find documentation for C functions.
  • Learn how to create prototypes for this type of function.
  • Discover simple useful functions like access() and system().
  • Explore more complex examples of C functions.

Session 2: Extend You Reach to Remote Data with Open Access RPG Edition

With the announcement of IBM Rational Open Access: RPG Edition, the capabilities of native RPG have been expanded significantly.  But setting out to write an OA handler can look duanting at first.  This session will look at what Open Access: RPG Edition is, and at how to use it to work with data in remote database systems using familiar file operations.

Learning Objectives

  • Understand the basics of Open Access: RPG Edition
  • Learn about designing an Open Access application and an Open Access handler
  • See how it all goes together to work with remote non-ibmi data sources


Hope to see you there!
