I just got a short email from him. He has seen or comments about typos on Amazon. I can ask next time I see him.
What page was it on...so I can find it quickly?? My book is at work so I can't check now.
Having written lots of documentation myself, I am always amazed at how I can read something multiple times and still not see some glaring error.? I can't imagine how much proofreading went into that very complex book...and they still missed a lot.? I guess that is what 2nd editions are for!
