Well, you *could* write your programs to handle the business logic in Java
and call those Java programs from RPG programs that display the results via
5250.  I'm not saying that anyone *should* do this, but I think it *could*
be done for the purposes of your demonstration.

Chris, I know this isn't what you're asking for, but perhaps what you guys
*really* might want to do is look into adopting more of an MVC model for
your development.  This way, you should be able to have lots of different
views (5250, Fat GUI, Web) and they're all independent of how you build
your model and controller.  Then, like Joe suggested, take a look at your
business requirements to see how you want to build your model and your
controller.  Maybe RPG's better for both, or neither or one or the other
depending on your situation.  Personally, I think that it depends upon your
particular situation more than anything.  Executives tend to like
platitudes and proclamations and have a one-size-fits-all mentality because
it's the nature of their jobs.  They can't get mired in the details.  But
they leave it up to the guys like us to get the job done, and sometimes the
one size (whatever it may be) just does not fit.
