Re: Will RPG eve become an object-oriented language?

Javier,

IBM S/38 CPF, OS/400, i5/OS and IBM i are all "object based" -- not really
"object oriented" systems. On RISC systems, the SLIC kernel is actually
written in C++ and uses "object-oriented" techniques, but none of that is
visible "above the MI" layer, in OS/400 or IBM i, as far as what the user
sees.

So, yes, IBM i has "objects" but there is no inheritance or polymorphism,
etc. that you can use with those "objects."

One thing to consider and have in mind is that the IBMi operating system
"is" an object-oriented operating system, and it is full of many types of
objects. So, why not drive RPG into something that supports the same
approach as its own host OS? :-)

I'm of the opinion that object orientation is a way of thinking - and

some

languages help to enforce its use. We can write code that is quite
object-oriented now - overloading might be a stretch. But we can think

__in

terms of__ objects, attributes, and methods anytime we want in RPGLE. In
some ways, I think we had __better__ think that way!

I would venture a guess that overloading, while a great feature, is

likely very low on the adoption scale.

Subject: Re: Will RPG eve become an object-oriented language?

It was discussed over 20 years ago and was rejected then as it should

be

now.

That's not to say that there aren't a few more OOP type features that

would be nice - and indeed some have already been added (overloading for
example)

This key question....mmmm...I like very much the evolution of RPG and

all

of its BIF's, and even DB2 SQL TR's related to supporting the latest

Open

Source technologies.

How about start thinking of turning RPG into an OOL?
Is that in mind at IBM?

I think that would be just GREAT!
