Vern,
Windows is still like that at its lowest level. The WinAPI (32/64-bit)
works the same way today as it always has. MFC, .NET and the new WinRT
frameworks are all wrappers for the same API, which has its roots in
16-bit Windows.

So ironically, it's my understanding that all the Windows OO wrapper
libraries resolve down to a procedural C API to this day.

Y'all
Ever since I started with VB3 in the mid-90s, I've heard about
event-driven programming. And I made the leap to, pressing a function
key is a kind of event - not all that different from pressing a button
in a GUI - and, hey, if you have PCOMM and turn on hotspots, it IS
pressing a button in a GUI!!
Windows in those days was a kind of cycle - hey, it really was!! It sent
messages in a round-robin kind of thing, and whoever could respond, did.
Events were a kind of message - I'm oversimplifying, of course, but it
makes enough sense for me.
So a Windows app consisted of a big select-case kind of thing, testing
what kinds of messages they wanted to process. Seems the same as most of
the display apps I've seen - run a loop until the F3 event occurs,
meanwhile process the ones you care about inside the body of the loop.
And RPG is very well-suited for this kind of thing. Even if you DON'T
turn off the cycle!
Just for thinking about!
