The Question is:
Hello --
We've been watching OpenVMS developments relating to COM/DCOM very closely, and
noticed the following listed under system requirements:
For OpenVMS systems:
OpenVMS Version 7.2-1 or higher
DEC C Version 5.6 or higher and DEC C++ Version 5.6 or higher (for COM for
OpenVMS application development)
DIGITAL TCP/IP Services for OpenVMS Version 5.0 or equivalent
Advanced Server for OpenVMS Version 7.2A or higher
Why are both the "C" and "C++" compilers required? We were under the
impression that the "C++" compiler is a super-set of the original "C"
compiler. Is this not true?
Thanks for any clarification.

The Answer is :
On OpenVMS, the C++ and C languages have separate compilers.
The DCOM MIDL compiler generates proxy and stub C code that
requires the C compiler. Thus if you are using C++ for your
development (as is typical), you need both compilers.
The OpenVMS COM engineering team has a goal of eliminating the
need for the C compiler in a future release of the COM software.
