The AI Tutor is for educational guidance only. It cannot connect to a real IBM i system, execute code, or analyze production code. Opening it from here shares this lesson's title and content so it can answer questions about it directly, without leaving this page.

Try asking: “When would I choose CAxx instead of CFxx for a function key?”
