Peter (et al): I have only one comment in regards to your thoughts (below). when you say projects to move off the mainframe have a high rate of failure, it depends on how it is done. One of the vendors I work with has superior success rates in regards to conversion/migration from a mainframe to an LUW environment.

If the core business logic is separated from the presentation layer" (i.e., if the business logic is well separated from the 270 screen processing logic), it might be possible to directly re-engineer it ith an HTML layer in place of the 3270 layer. If the screen-handling and the business logic are tightly woven together, not so asy at all. I have no experience at all with IMS applications, much less with interfacing hem to web browsers, but if the "business function" is well separated from the user interaction" parts, it should be possible. Such projects are never easy, though. Sometimes, unfortunately, the best ecision (financially and time-wise) is to start over from scratch. For a staff ith limited z/OS skills, that could result in a project to move completely off f z/OS. Those kinds of projects have a very high rate of failure. One other possibility is the use of one of the several "3270-to-browser" onversion products I think are out there, which (if I understand the functions rovided) take your 3270 screen inputs and outputs and convert them back and orth in a web browser. Not pretty, and almost certainly affects round-trip ime from "enter" to results screen, but supposedly quite functional. All I can say is good luck. You're going to need it.

I'd be grateful...
