Exactly Mark.  How much of OO is concept, architecture, and design?   It can
t be 100% language-dependant can it?   Isn't a date data-type as we know it
in RPG an OO thing in nearly every respect?

I have dabbled w/ Java (and done some reading), so I have some clue about
OO concepts. We've been discussing pseudo-OO programming via RPG IV
procedures.

Changing or adding a language for most business shops is a *very*
expensive proposition and a large risk. The ROI in most cases is just not
there. You will probably lose some people w/ extensive knowledge of your
business. For new technical hires you will have to find someone
experienced in both languages.

Extending RPG has encouraged us to hone our programming skills. While
modular programming has been encouraged more a long time, procedures have
made it easier to implement. I believe that moving RPG forward toward
capability will make it a LOT easier to ease into OO. JMHO.

I agree.
