Re: EGL and RPG - The Fastest Path to the Future

I think it's disingenuous to say that RPG is the best language in any situation.

I know from experience that indeed RPG programmers mostly focus on business problems, not technology. And this is not a good thing. You have to focus on both. Both are important. If you build an app using EGL and RPG on the server than you have to decide which part goes where.

In my experience most RPG programmers never really think about how to implement or architect application.

Sounds like your saying "Because I have a hammer, all problems are
nails". I think its important to look at the problem and find the best
tool for the job. I think it's disingenuous to say that RPG is the best
language in any situation. Also, business knowledge is not something
that is unique to RPG programmers. I would argue that there are other
languages out there that are just as effective, or better for
programming business logic than RPG. But, you've got to get out there
and try them out and write sophisticated apps with them before you know
the answer.

I'm not trying to start a war or disrespect anyone, it just seems to me
that some people on the list don't want to look at the realities of the
industry and instead want IBM to build upon their language of choice.
I'd like that too, but it appears as though that isn't going to happen.

If it works then it works (until it doesn't and then we fix it). So yes, we get a big mess with code everywhere on the server and the client. Not to mention all performance problems because lots of code is executed on the client where it would be more efficient to put it on the server.

It's going to be a mess....

Web applications are required, networking is required, multiple inputs

devices are required.

I would whole heartedly agree that web applications are required, because
afterall everyone has a browser installed by default on their PC desktop.
But that doesn't mean I should reformulate my entire approach to software
development because of a handful of customer facing applications, should
it?

No, the application it split up into tiers: database, business logic,

application control and user interface. This is the way it should be,
because it means I can add a new user interface without changing the rest of
the application. That's where EGL shines!

I won't digress into my "single language" comments here, but would like to
state that I believe RPG shops adopting EGL for the front end will most
likely start to migrate their business logic and DB IO into EGL also. I am
not saying "how would Joe Pluta do it" because you like having RPG on the
backend, but the reality is that most people will go for the one language
environment, and being EGL is the new kid on the block with a fresh look I
would say it will inevitably (and gradually) take over the other areas of
the programming stack. I have found this to be true in cases where
Microsoft technologies have been adopted. Would you agree on this point?
