I have to assume Jeri's right, Jon. Most of my computer courses required documentation of asinine things that, to me, we self-evident. But when I started writing major programs, I made sure for those who'd have to work with my code later (analysts and/or programmers) that every section was commented with what the code in that section was designed to do. I hope he's misused the term 'users.' I doubt the normal user has the knowledge or interest for the comments to be of any use.
