After working on a variety of systems for over a dozen years, Jon was introduced to the System/38. This began a “love affair” that ultimately led him to join IBM’s Toronto laboratory, working on the S/3X and AS/400 compilers. While with IBM he played a major role in the definition of the RPG IV language and in promoting its use.
Jon left IBM in 1998 to focus on providing IBM i users with education and consulting services to enhance their application development skills.
Together with his partner Susan Gantner, Jon runs Partner400, a consulting company focused on application modernization on the IBM i platform. Partner400 are also one of the founding members of the System i Developer education consortium – hosts of the RPG & DB2 Summit events which are held twice annually. Jon and Susan also co-authored IBM’s Redbook for RPG programmers, entitled: Who Knew You Could Do That with RPG IV – A Sorcerer’s Guide to System Access and More. They are also technical editors for IBM Systems Magazine – IBM i Edition and you can follow Jon and Susan’s blog at http://www.ibmsystemsmag.blogs.com/idevelop
