IBM Bob Creates a Detailed Design Document from a Decades-Old RPG III Program
Nobody's looked at this program in years and no one remembers exactly how it works. Bob reads it line by line and writes the design document that should have existed all along.
In this video, see the Premium Package for i generate a complete design document for an old RPG III program. Bob reads the program line by line for full understanding, then expands its analysis to every referenced object — logical files, physical files, and display files — to build complete context before writing anything.
🔹 What you'll see in this video:— Bob reading an RPG III program line by line to understand its full logic— Expanding analysis to referenced logical files, physical files, and display files for complete context— Writing the design document directly to the IFS— Document contents: overview, purpose, program interfaces, and external dependencies— Detailed flow diagrams showing how the program is structured and how each piece connects— Section-by-section breakdown: indicators, messages, and program logic— Observations and notes capturing anything ambiguous or worth flagging
📌 Key takeaway: Decades-old RPG III programs often have zero documentation and the people who wrote them are long gone. Bob reads the program and everything it touches, then produces the design document that was never written — overview, flow diagrams, dependencies, and observations — turning institutional unknowns into something your team can actually work from.
