Re: Open Access RPG

Jon and Susan wrote an article or more about Open Access for IBM System
Magazine (www.ibmsystemsmag.com). I did a quick search and came up with
this one: http://tinyurl.com/JonSusanOA . There may be more.

I think there were a few articles about it in iProDeveloper.com but can't
remember if it was Scott or someone else who wrote it/them. IT Jungle,
also, has some articles. But you get the idea. Google is your friend - if
you use the site: parameter.

Here's some small samples. Probably not what you were expecting. They are
only intended to demonstrate the linkage between the RPG program and the
handler. They don't anything exciting, and for sure they don't do anything
as gigantic as "hello world" in a browser. ("hello world" vs a "real"
browser application is similar to a non-paved bridge vs a paved bridge.
There's no such thing as a little starter bridge that anyone can quickly
build and try.)

Open Access doesn't contain any function for putting content in a browser,
or for doing anything else. It only _enables_ getting to that function using
RPG I/O opcodes.

Basically, Open Access is just a conduit that passes I/O data between the
RPG program and a "handler". It is the handler that does things like show
"hello world" in a browser, and Open Access doesn't contain any handlers.

Another way to look at it is that it turns I/O opcodes into a call to your
handler. Then it's the handler that does _all_ the magic like connecting to
a browser or accessing a remote database or working with a data queue. Open
access just makes it super-easy to call the handler.
