Re: EGL in 15 Minutes

["Dave Odom" <Dave.Odom@xxxxxxxxxxxx>]

Joe,
 
Thanks much for the info; what I was looking for.  
 
Like the idea of host variables; shows a better tied to what you do in compiled languages.
 
Is the Sayles website in your IBM article for which you sent the URL?
 
I think WDSC is on the i5 I use but in case it isn't or is old, how does one get EGL?   Is it part of the i5/OS or a program product or what?
 
Thanks,
 
Dave

EGL has direct support for JDBC access when generating Java.  So you can
basically embed your SQL statements and then execute them, directing the
results into host variables (including auto-sized arrays).  Very powerful
stuff.

Me, I still prefer RPG because I consider it the best tool for the job, but
that's a personal preference and no sense dredging up that particular
argument, eh?  <grin>

I don't know about compare and contrast.  Read the article, and read my
other EGL articles.  The EGL syntax is a very high-level declarative
language, much simpler than Java or C# or PHP.  It's based on records, which
are data structure with meta-data.

If you're using WDSC, you can download a trial of the RBD extensions and
take it for a test drive, or go to Jon Sayles' website for lots of tutorial
information.
