True - but it's quite easy with CEERTX or CEE4RAGE - and it's not quite so easy with a stateless protocol where the application has to handle state itself.

We use CEERTX a lot - simply register your "finally" procedure and even it your process gets killed with ENDJOB *IMMED, your procedure gets called before the end and has the chance to clean up or rollback coordinated.

I also use CEE4RAGE sometimes to register an exit procedure for an activation group - but not so often.

I know, for all of them are solutions available, but never as easy like
green screen development.

The web design gives you a wide range of options, a black and white
web
page takes less time than DDS to design and it looks a little better
than
green screen.
It can later be made prettier without changing the program.

As for the speed, writing the CGI in RPG is very fast.
The web got a reputation of being slow because of screen scrapers,
php,
java, PC in between, and other options.

As for data input out of the office, it is much easier to find devices
with
a browser than with a green screen.
Any celular phone can be used, connected everywhere, it can read bar
code,
QR, upload sound, pictures, etc.

What Vern has written at the end of his post is the truest of all -
everyone is right and everyone is wrong.

Having been around a long time, in many different industries, I will
suggest that one industry to the next, and even one department

within
a

company to the next, will favor one or another.

Look at retail - so much of the software on the platform is written

to
the

green screen. However, once you move to the back-office, HR and

such
would

like a pretty GUI interface over their parts. Transportation is

another

example - dock operations traditionally wants a green screen for

speed
of

response, whereas, dispatching desires a pretty GUI since their data

will

be interfacing with routing software.

To mandate one or the other could, and would, be adversely received

by

different individuals in different functional departments based upon

how

they utilize the system.

Arguing over UI is just another version of "best tool for the job"

and
not

that just because you as a developer want to write pretty GUI and

not
green

screen (sorry that you need to be multi-faceted) and provide the

user
the

experience that best suits their needs. Put aside your

developmental
bias

and remember what we do isn't for our sake or use.

Yet again, just one man's thoughts.

I have long felt that a graphical interface (browser or something

like

Visual Basic or C#) is slower for heads-down data entry, since it is
primarily eye-driven - for it to be otherwise requires careful

design,
as

you suggest. Use of the mouse is a visual thing - 5250 with good

screen

design is like touch-typing, with newlines and tabs, your navigation

is

mechanical.

I think both of us might be as right as the other, as wrong as the

other,

I am not comfortable with an all-or-nothing statement about these

things -

not even mine!
