Re: IBM pushing Java

Hello James,

Not a bad effort at all (in my not so humble opinion). See my append to Booth 
about some of your points.  The 
one I most wanted to discuss here was the DDS/record analogy.

I think a record can be visualised as an Entity therefore a record in a 
Customer Master file can be thought of 
as a Customer object.  In this case it is a fully populated Customer object.  
An empty record (INZPFM etc) 
would be like a shell Customer waiting to be populated.

The DDS for a file is more like the class definition (template) for a File 
object.  This class is instantiated 
via the CRTPF (or CRTLF etc) command.  In the same way RPG source is the class 
and CRTRPGPGM instantiates the 
class and gives us a Program object.

Who said the AS/400 isn't object oriented?  Yes, I know it's object-based but 
when CPF was designed OO WAS 
object based.  Inheritance, polymorphism, etc came later.

Regards,
Simon Coulter.
