Paul,
I was going to flame, but you did it for me. Your final "kicker" as you put
it is what I was going jump on.
The thing is, program FOR the AS/400 is the best thing to do. Programming
ON the AS/400 is not the best.
Whereas, programming ON the PC can be a wonderful, and often the best thing
in the world (for a programmer). But programming FOR the PC (namely
Windows) is not the best thing to look forward to.
After how often do you spend day after day trying to debug a application on
the AS/400 that blows up once in while, when the cursor is moved into a
certain field? Or when the mouse is clicked on a certain part of the
screen? I would say, never. You get to spend time coding our business
rules, and database manipulation routines. On the PC, you almost never have
time for the later, because you're so busying trying to figure out bugs in
Windows ("The GUI environment without a brain").
IBM did an informal study a few years ago. On the AS/400 80 percent of the
time was spent coding the application function, whereas 20 percent or so
was spent coding the user interface. On the PC, however (Windows
specifically) 20 percent of the application development time was spent
coding the application's function, whereas 80 percent is spent coding the
user interface. This doesn't mean you code PC apps faster, it just means
you spend a heck of a lot longer debugging and coding your user interface.
If IBM had only listen to us way back when COMMON was in Miami (early 80s).
We told them at that time, that we wanted to start going graphical. The PC
was brand new, and we wanted to us it as a 5250 device to avoid having two
hunking devices on our desks.
The main problem, the way I hear it, is that today, the "big customers"
that sill use dumb terminals keep telling IBM things like "GUI is okay, but
you gotta make it work on my existing terminals too" or "Go ahead and do
it, but don't abandon my 5250 devices".
In my opinion, IBM interpreted these comments as "don't do GUI on the 400".
When what they (the customers) where really saying, is "DO GUI." I suppose
you could follow that with, but don't _remove_ support for the 2,000 dumb
terminals I have installed. This to me means "go GUI", and add it to new
apps that you produce, including operating system interfaces, and make it
work with Windows, or whatever, but don't initially do a wholesale rewrite
of the user interface that makes my dumb terminals not work with the 400.
After all, people do embrace new technology after a while, but they really
dislike throwing away stuff that they've already paid for, and still works.
