As far as entirely getting rid of the 5250 interfaces, there are simply
too many systems developed on these. The manpower to replace them would
be just as easy to replace with a competitor's product. I don't foresee
IBM ever removing the 5250 interface. On the more recent systems, there
is no interactive tax. The interactive tax was IBM's way of trying to
push people off of the 5250-interface. It failed. They've since dropped
Actually I think that the best thing IBM could do was to introduce a NEW
5250 screen mode (or whatever it is called) which can _resize_ instead
of being fixed to 132x27 or whatever, where the things displayed can
adapt to this.
So if you were doing e.g. a WRKLNK you would still have 6 lines or so of
status information, but the rest would adapt to the screen size,
allowing you to full screen a 5250 emulator and see perhaps 50 lines of
This is how it is done in Unix, and it has worked very well for them,
and they do character screens all over.
Unfortunately I had a look a while back and all the 16 types available
in the four bits were taken. Sigh.
From those more experienced than me, COULD this reasonably be done?
