I am excited to announce that I have refreshed the RDi hands-on labs that are available to everyone at http://ibm.biz/rdi_labs
The labs are now at RDi 9.5 and will show off new features like the embedded emulator. Over time we would like to add some new labs for brand new features of the product. Now that it is a part of our local wiki, it will be easier to update.
All the necessary libraries, and compiler (supporting fully form RPG) is supplied by IBM on a publically available IBM i. For those don't have RDi, just download a trial, for those who do, have fun exploring features you haven't put into your regular toolbox yet.
