I dont like Visual environment. It is bad for development of
expertise in programming. However, =real= OOP isn't the same
than Visual programming. Heritage, Methods, Polymorphism &
things like this. Source code in OOP is dont *easy* to write.

I am studying this yet, but Visual & OOP are not the same thing.

Not sure just what you mean by your question.  For Intel 80x86 architecture
machines, the Ring number relates to what a program is allowed to do (it's
privilege level).  A Ring 0 program has access to all memory, all I/O, all
registers.  A Ring 3 program is much more limited.  The operating system would 
run at Ring 0 while a user program would run at Ring 3 to allow protecting
user programs from each other.

Are you saying it is or is not easy to write object oriented code without a
visual builder?  I personally find it pretty easy.  Much easier, in fact,
than doing things procedurally.

 RCB> I am studying this yet, but Visual & OOP are not the same thing.

Naturally, but most visual environments deal with an OO language (usually
C++).

I can achieve that here too.

But afterwards, everything stops for about 15 seconds while the disk cache
catches up.

Take care,
