MVS console on 3270 is confusing

OK, I was confused about the MVS IPL on a 3270. This drove me crazy yesterday. I seemed to be able to logon HERC1 and submit jobs. But D A,L didn’t show very many process up. How can this be. Well come to find out it has to do with how the 3270, displays messages…it’s different. Perhaps it’s a TK4- thing? My MVS operations skills are very weak. Press PF8 which does a K D,F to display the rest of the messages. So D A,L wasn’t showing all the running systems (if that’s the correct term). VTAM and JES2 were up. At this point I’m not really sure what I’m talking about. But it has to do with areas on the screen and something called Roll Delete. You can manipulate this with various Console K commands.

BTW. This is a good 3270 startup for a console (larger fonts)…
