Jeff, you can download a 60-day trial of RBD (Rational Business
Developer) from IBM. If you have a real application in mind, IBM has
free distance learning courses and there is an entire ecosystem aiding
people who are getting started, including folks like Claus Weiss and Jon
Sayles.
There is a ton of online documentation as well as an entire website (the
EGL Cafe) dedicated to the language.
An EGL application is a standard browser application, and currently EGL
has a JSF interface (which is what the folks here consider a web
application) that will run inside any browser, including most handhelds.
What's really cool about EGL, though, is that it doesn't stop there.
The next generation of EGL (the next drop of which comes out this week)
includes a powerful rich client interface that easily interfaces to all
the popular JavaScript frameworks like Dojo and Google.
While I respect the programming ability of folks like David and Nathan,
the truth is that there is no way they will be able to keep up with the
new technologies. Heck, Aaron insists that WebSphere is too hard; I
can't begin to see how he's going to learn Dojo, YUI, Google and jQuery.
By using EGL as your interface, you let IBM do that work for you. David
doesn't like that, because he doesn't have control over it. Valid
point. But a lot of businesses they want to see results, and EGL will
get you there quicker. Not only that, but David's direction involves
hiring help, while EGL's strategy is to encapsulate the complexity so
you can do it yourself.

Joe,
In all seriousness, how should I go about learning EGL?
I'm dyed-in-the-wool RPG (subprocedures, service progs, etc), some SQL
(all DDS converted to DDL), a small part of CGIDEV2. We're looking into
wireless access for the warehouse. Once that's established (and it's
not a for-certain) and we have handheld laser scanners out there, I have
a number of applications in mind. These handhelds (Intermec or Symbol
or whatever) will have 5250 emulation, but I'm thinking of a web
approach for these new apps. The vendors I have talked to so far have
never heard of EGL. If the handhelds have browsers, will they "run EGL"
so to speak?
Thanks.
