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

has

been investing in Open Technologies that are being created to

interface

with our existing back end programs. Its why we have REST Api

engines that

are delivered with the operating system. To allow our IBM i customer

to

move in to this 'normal' world. Not only do we have many options

that

allow you to do the work, we have a wealth of great ISVs that

provide

tooling to help you make this transition in a fraction of the time

while

in many cases leaving your existing code virtually untouched. If you

are

interested in getting a view of some of these ISV, please send me a

note

and I can get you a list.

Or if you need more info on the options in the Open world for IBM i,
please let us know.

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.
