To all those who responded....OK, OK, I spoke in hast and obviously as a relative newcomer to VM. I admit I had overlooked the normal DIAL facility. In the face of that I will have to reinvestigate my pat answer for why multiple 3270 support was not done. It may have been an arbitrary decision as one poster suggested or perhaps there was a deeper reason. If I learn anything useful I will post the answer. >I suspect that the actual fact is that the 3270 support just wasn't >done. What would you run there?

Not a bad stab at a reason Nick, however we do actually provide a 3270 terminfo module, and you can run vi on the 3270 console although it behaves so strangely that I can't imagine anyone wanting to use it other than to say "See it can be done.". This whole thing has peaked my interest in the matter and I am going to try and find a definite answer. As for curses, Oleg could elaborate on this since he worked on this code, the installation/maintenance package actually does full screen menus with highlighting and such on the 3270 console. Not to say it isn't a kludge but we have done it. To Mike and Terry from Amdahl, since I have never used UTS, I am curious. You say it supports 3270 access, how does it handle their block-mode nature with regard to vi and the like? I have seen MTS at U of M and I don't think it has this problem since it is set up for such terminals, rather than running software designed in the async world (again, I could be wrong here since I only had a brief glance at it).
