RPG IV - Subprocedures
RPG IV introduced the concept of built-in functions to the RPG programmer, but many still do not fully appreciate the power and flexibility they can add to your applications. As powerful as this support is though, it still can't provide every possible function that your applications will need. Enter user-defined procedures. Introduced in V3R6, these open up completely new ways of building applications. In this session you'll be introduced to the basics of writing Subprocedures, and learn how they can help you build more powerful, modular applications.

He currently works as a Senior Consultant for Hal North America Limited. Jon's S/3X career started when he fell in love with the System/38 while working as a consultant. This love affair ultimately led him to joining IBM. Contracted by the Toronto Laboratory, in 1987, to work on the S/36 and S/38 COBOL compilers, Jon became involved with the AS/400 and in particular COBOL/400. Invited to join IBM full-time in 1988, Jon continued to work on COBOL/400. In early 1989 Jon was transferred to the Languages Architecture and Planning Group, with particular responsibility for the COBOL and RPG languages. In this role he played a major role in the definition of the new RPG IV language. In 1994 he moved to his current position where he is involved in producing educational and other support materials and services related to AS/400 programming languages and development tools, such as CODE/400 and VRPG.
