If I am thinking about the same formatting classes, yes I think they are
using them in the background which is totally transparent.

When I was talking about the class files being built without regard I meant
the display tier.  So my screen driving classes don't need to know if they
are being run from within a web server or locally on a Windows machine.

I agree, and that concept fits into the environment just fine.

I guess I'm a little confused here.  The only class files I've ever written
that knew about the web were the formatting classes.  That's the idea of an
n-tiered design.  If you don't have that separation of tiers in your
application, then you aren't ready for web design anyway.

Of course, if your idea of web applications is big, monolithic RPG CGI
programs, I could see how something like .NET might seem like a step
forward.  But in a good tiered architecture, RPG programs don't have any
idea what type of UI they're talking to, so they can talk to anything.
UI-independent RPG programs are the best way to present business logic to
ANY user interface, including the web.
