While it's true that 5250 has been around and in itself is not being significantly improved, I'm not sure that that's the whole story. Two major elements seem ignored. First, the old physical workstation controllers are fading fast. And second, though the data stream is more or less unchanged, there have been significant "enhancements" in how the system supports it. I have no figures, but I suspect the majority of 5250 is now TN5250 or TN5250E. (Personally, I believe IBM did a superb job in getting TN5250 defined and then implementing it in AS/400s. This was done before CFINTnn became a significant issue.) Adapting existing 5250 support to handle TN5250 could not have been a cheap undertaking. TN5250E brought user/password and named devices, both major items. The point is simply that 5250 is in fact being enhanced and supporting it must be almost a pure iSeries cost especially now that TCP/IP is no longer a chargeable item.
