Sorry about that.  It seemed wrong to write ANSI/ISO C++; is there a version
number like 3.0 or 4.0 that identifies the set of features expected for
ISO C++ (and is already in some current C++ compilers)? I just wanted those 
non-C++ folks out there to know that dynamic_cast is a feature that 
is anticipated in the ANSI/ISO C++, and might not be familiar to 
those of us who have only read older C++ reference manuals.
