Hi!
Thanks for fast reply!!!

See Note 483 in the conference TURRIS::C_PLUS_PLUS, especially
replies .87 and .111

| According to the article by Gerry Therrien, the product manager,
in the latest Sales Update, DEC C++ for OpenVMS VAX V1.1 is
orderable immediately.
DEC Trellis is also available (Owl is part of Trellis), but before
taking any orders you ought to check the product's status with the
product manager, Jerry PIPE::Smith.
Other OO languages such as Smalltalk, Eiffel, Modula 2, Modula 3,
Objective C, etc., are very likely available from third parties.

| And Modula-3, although (IMHO) an excellent, object oriented language,
is unfortunately still not available for VMS :-(

Many would not consider Ada to be object-oriented, but on the
other hand - many will. Whether it is or not (and especially
if you want it to be), it has great marketing advantages for
Digital for its good & long reputation.

| I think ADA is called Object-based as opposed to object-oriented.
please dont ask me what is the difference or what this really
means ;-)

| Ada 83 is generally regarded as object-based, or supporting object
oriented design, or some such.
Ada 9X will be truely object-oriented.
The biggest difference is how you can have the following case..
root-type
operation Q
operation P(X : root-type) does Q(X)
extension-of-root-type
operation Q is redefined
P(object-of-extension-of-root-type)
which Q is called?
In Ada 83, there is a good chance the root-type's Q is the answer, and
you have to work hard to get the extension Q.
In C++, Ada 9X, and other OO languages, it is easy to get to
extension-Q.

Bertrand Meyer, in "Object-Oriented Software Construction" defines seven
so-called "levels" of "object orientation". Peter Wegner also deals with
the definition of an "object oriented language". The general conception
is that "OBJECT BASED language" has featues for encapsulation, data
abstraction, etc. These features define the "objects" (or "classes").
An "OBJECT ORIENTED language" has *ALSO* the notion of using modules
as types (e.g., "package type", array of packages) and then introducing
inheritance between the objects (e.g., sub-package).
However, there *are* arguments which say that some aspects of inheritance,
especially when misused, may hurt the original intention of the whole
methodology, which was meant to assist in integration and maintenance.
