Almost every RPG programmer who learns SQL asks the same question: Do I keep using RPG's native I/O operations, such as READ, CHAIN, and WRITE? Or should I replace them all with SQL? Which method will be the standard in the future? Which method performs the best?

In the podcast, Susan mentions IBM's DB2 for i website. Here's a link to that site for your convenience:
