Nathan,

You're only partially correct. The application would need to be rewritten, to some degree. But, the additional cost of the add-on product plus the additional development and testing overhead made it too expensive an endeavor to undertake, from the clients' perspective.

I went through this at several medium to small clients. Had IBM included and integrated this functionality into the OS I would have created some standalone mini applications, or a parallel function to an existing application, and let them get used to having *their* data displayed in a real GUI, with additional functionality.

There is no way that they would shell out for an expensive tool (plus the yearly maintenance!) just to try it out to see if they want to go in that direction. There are other details in play, but that was a big part of the decision.

The fact that we can get a GUI to display does not mean that this is an inherently a GUI OS. It's not. IMHO, until IBM decides that it's worthwhile investing in creating a fully integrated, modern interface as part of the OS, this box will be perceived as old and dated. That's a shame, because it's a real workhorse with many innovations and capabilities.

Mark,

In fairness to Tim and other folks at IBM, it has been my experience that
when organizations migrate to Windows or Linux and Intel, it has little to
do with the fact that IBM hasn't provided a GUI, or bundled it with the
operating system. The real problem was that the organization ran into
constraints within (in order of priority):

1. A legacy database (e.g. dates stored as 5-digit numeric; the list goes
on and on).
2. An application architecture that was resistant to change.
3. An IT organization who failed to respond to new requirements in a timely
manner.

In regard to the IT people, the nail in the coffin that sealed their fate
was their proposal, or adoption of a screen scraper, and an attempt to
cover up the more relevant issues delineated above.

It had nothing to do with the cost of the screen scraper. It always costs a
lot more to migrate to Windows or Linux. In addition to the migration cost,
the ongoing operational costs are higher.

Tim,

I was discussing this subject recently with a very respected member of
this group. We were both confused how turning over a crucial, and I do
mean crucial to the longevity of the system, piece of creating a modern UI
is turned over to third party vendors instead of being fully integrated and
included in the OS.

Some vendors have done an admirable job creating a product, but IMHO,
it's ridiculous to have to pay a large bundle extra to get what should be
included and easily integrated into the system. It is also more expensive
to develop using (at least) some of these tools. My estimate is at least
25% longer to develop and test.

I have three clients that are jumping ship to a PC based platform,
another that has already gone in that direction (they used to have the
largest AS/400 config in the US northeast (which included 14 AS/400's) and
another is in the midst of moving part of their operation to a PC based
cloud system. I haven't heard of a new member to the midrange fold in a
long time. I would imagine that they exist, but I think that 20+ years
after the GUI became popular, for IBM not to include this required
functionality, plus the GUI development tools as part of the base OS, is
just plain foolish.

No offense to the tool vendors, but I believe that this functionality is
best integrated at a low level in the OS, not as a generic API in order to
get the best integration, debugging and performance.

Yes!! Moving from Green Screen to a Mobile or Web based interface is
being requested by many. Not just your either. In todays world its
really
becoming a necessity. That is one of the reasons that the IBM i team

subject: Re: Moving from Green screen app to GUI because of push
back
from younger employees?

Go ahead with the change.? Go to web.

We began the change 20 years ago. Some user where against the new
interface, and we had to restrict the green screen, but when we put
it
back on, the users stayed with the web.

Once we learned to use the web, none of the programmers wanted to
do any
more green screen programs.? The web gives a lot of resources , and
frees from the limit in the size. You can replace one program at a
time,
and run "hybrid". Usually, by replacing just a few programs you will
take most of the work to the web.

We use CGIDEV2.? It replaces the "screen" with a "mask" in html and
the
RPG logic remains very similar.? (assuming you have small - one task
each - programs)
A good web designer can do the "presentation" without knowing RPG,
and
you can use it with minimal web knowledge.? Basic html is simple,
but
not spectacular. Even so, it is better than green screen.
