More developers are learning about the IBM i as a wonderful business platform. (It was formerly known as the AS/400.)
This repository contains working example code, using RPGLE free-format, enbedded SQL and CLP for the IBM i.
My intent is to provide real programs that help you learn and/or improve your current understanding. Explore and adapt the code to your needs. Some of the code may be of use "as is" but no guarantee is provided.
