Re: 20 years ago

The choise of the wrong tool is why the GUI will not be better than the
green screen. An extra server is a usual source of problemas, plus it is
slower.

Using RPG with a service program to read the data and merge the results
with the HTML gives the same easy to build, fast, reliable programing
environment.

PHP is slower, and to make it safe requieres a lot of cleaning the input.
Plus, the html is mixed with the logic.

Change is never very easy, but once you get the hang of web programing

you will never want to go back to program dds for green screen.

To me, the real strength of the platform is how effortless applications
with a full-screen interface and embedded help can be developed. I'm simply
not interested in web programming. If I were I probably would do it on
Linux anyway with a much bigger community and an overwhelming amount of
readymade PHP code to pick from. But that's my personal opinion.

In context with the original poster's question, I still assert hat your
suggestion is over the top. He was asking for advice for one screen to be
built with windowing support. One screen of most likely many, being used by
probably many users. And you told the OP to just throw this all away and
start to convert to browser-based approaches instead. This seems
ridiculously naive to me and — as stated — not the slightest helpful to
answer the OPs immediate question.

Web pages can be navegated using tabs

On 5250 I can utilize group jobs which provide a similar functionality if
I'd be in need.

and with the help of javascript you can advance fields and records.

This is the only thing I admit is something 5250 doesn't provide: A
generic (programmable) way to interact with entered data on the client
side. This can be seen as a problem, or as a challenge for the programmer
to find other ways to build a screen which works well without such
immediate interactivity.

A big help is to use the mouse with the left hand.

Learning to "mouse" with the "wrong" hand is really cumbersome. Much more
than memorizing to use the Tab-Key.

Web programs receive a request, produce the output and disconnect. Does

not tie a session.

I don't see any relevance in your statement.

Most of the time they are short and easyJet to mantain.

This might be true from your point of view and experience. I'm not arguing
over the truth of your claim from your point of view. I'm just trying to
make you aware that asserting "web interfaces are always better and always
easier to program" is just not true. Especially when considering your
statement that "you need to get the hang" of it, first.

:wq! PoC
