It had run all day with nary a hiccup and I was at the console helping an operator with come commands and just generally chatting with them about the differences. The VP for the DC was walking by and listening to me talking. I think there were 12 people in the office. So, I go into the pitch trying not to be to technical as with the operators. After we finished the chat, he suggested that I come into his office. Suddenly, he gets on the phone and invites all the managers in to listen and ask questions about the new OS. His office was large but not huge. The shift managers were a hoot as it seems as though they had lost touch with operator type functions they had no idea about premounting tapes and the different operator commands and the concept of a virtual address space. I spent more time explaining simple things about how address spaces were mapped (keeping it simple). I started out with a flip paper board, and I ended the talk at about 7PM and had very few questions. Most of them loved it as there were so many restrictions on VS2r7. The news spread quickly and for the next 5 days I was booked in every programming group in the building. I was happy managers did not attend any of those sessions as I got some stupid questions from the programmers. My stupidest question was since s222 is a system bend why should he have to debug it, since it was a system abend it must be a system problem. UGH!. Ed
