Re: Is OOP a paradigm or methodology?

Thank you for visiting the Z++ site, and your kind comments.

I was 22 when I taught calculus at college. After working on my second
Ph.D. in computer science (the first was in mathematics), and over two
decades of professorship, I left academia and became a programmer. Ever
since 1996, my title has been Software Engineer, although everyone
calls me Dr.Z. I am still working as a software engineer (started with
insurance applications, then financial, then wireless etc). I did that
precisely for what you are saying. I have a feeling you will agree
with:

Neither does Z++. In fact Z++ includes a lot of ADA (coherently,
properly designed). I realize you have not tried Z++. If you choose to
do so, it is free and does not even require an email.
By the way, Z++ includes all the great work from APL, Eiffel etc. The
important thing here is how Z++ brings together all these great ideas
from other languages, with minimal learning curve for a C++ programmer.
However, seeing is believing.

At any rate, Z++ includes C++ as a small subset with corrections. It is
not like using C pointers to add Simula classes to C. However, your
perception is appreciated. Someday Z++ will be understood.

I remember the proposal for ADA 95. I was glad the constraint of not
admitting a superset was dropped. You may like reading the following.

The spectrum of software for Z++ is Application Software, for
distributed, platform independent applications, from PDA all the way to
mainframe. Apart from expressive features of Z++, ADA cannot do all of
that. The ADA compilers that will be ready will not work on
cell-phones. (I have not written code in ADA since the last time I
taught it. Which was well over a decade ago).

At any rate, ADA and Eiffel and C++ are all great languages. But they
cannot cover the entire spectrum of ever-changing computing devices, as
Z++ does. The domains of problems are not the same. Z++ sees the entire
heterogeneous network of computing devices as one abstraction, for
distributed applications. In particular Z++ does not compete with any
of those languages. It merely coexists with them, doing what they are
not meant to do (and thus will never be able to do).

I appreciate your bringing up this issue. Perhaps I need to work on it
much harder.

Your point is well taken.

You brought up several fine points. I had to clarify a few things.
Sorry for the length.
