I'm not sure if this is the right list...

I'm looking for advice/suggestions on how to change an RPG/green
screen application to be accessible from a browser.

Last week I was at the RPG/DB2 conference in Minneapolis. A great
conference as usual. I was particularly interested in the open source
sessions and I'd like to try some of the techniques I watched being
done.

The shop I work in has been a single person shop for a couple of
years now (down from three people). All of our software was developed
in-house over a period of many years. The code is mostly RPG400 and
green screens. I write any new code using RPG Free and other newer
techniques, however the applications are pretty stable so I don't
write a lot of new code. My other responsibilities (PC's, networks,
and so on) keep me from doing any refactoring.

The program I'd like to change is an RPG Free program that uses a
green screen display to show current yield data to the manufacturing
line (it displays a bar chart using control codes for different
colors). It's displayed on a large screen TV that is visible in the
plant. It refreshes every 15 seconds.

I'd like to update this process and move the display of the data to a
web browser so it can be visible to those without an IBM i client.
This is not an area I have much experience in. The closest I've come
is using CGIDEV to create a web page that displays sales data.

My question is, where to start? I've spent some time on the web
looking at various ways to do this, I think there are about a million.
What's the best way to ease into this?

To help narrow options down a bit, I know RPG, C and SQL. I've done
some simple HTML and CSS. I'm familiar with linux. I built a simple
inventory app a few years ago using a LAMP stack and PHP. I'm
currently learning Python.

Any and all suggestions are welcome.

Thanks, Kelley.
