Re: Classes/Objects compared to SRVPGMs

my one and only statement regarding this whole subject....they both have
their purpose. one is not *better* than the other but instead they
complement each other. each language has it's strong suits, using both
languages leveraging their strengths is the best possible scenario. Java
is great for GUI rendering and lightweight UI in general, RPG is great for
business processing, tie them together and you've got a great team.

Thanks,

What I do want to point out - and yes, I will keep on hammering about
that ;) - is that 'old fashioned' programming styles (what we are used
to and love in RPG, Cobol, C and what have you in that area) can never
be compared in functionality and use to OO programming styles with the
whole concept of inheritance and reuse through classes/objects and what
have you which is used in Smalltalk, Java, C++ and the likes.

I'm not going to get too far down this particular alley, because it's a
blind one, but the idea that OO programming is inherently better than
procedural is a topic that's been beaten to death here, Cor. The
suitability of a giving programming technique for a given purpose
depends a lot upon the programmer, but the idea that RPG can't provide
code reuse is simply untrue.

We can argue all day about whether inheritance is actually a benefit -
the OO experts seems to be leaning more towards composition rather than
inheritance as it becomes clear that complex object hierarchies lead to
brittle software - but at the end of the day, the trick is productivity
and procedural programming still has its place.

To insist otherwise is to have never written business logic with a good
procedural programmer.
