This looks like an old posting...is someone along the line burping up old
postings again??

Ted, this makes no sense.  First of all Zortech's C++ is only targeted (as far
as I know) for the intel iapx80x86 family of processors running OS/2 and
MS-DOS.  Unless it has been retargeted for the 1750 or some other popular
flight qual'd processor I would doubt that this comparison makes any sense. 
The second thing is that the run time efficiency of the code can not be
compared to the compile speed...just to the code generation quality!  Third
thing is that in an embedded system maybe due to less overhead some certain
implementation of a c++ compiler will beat some certain implementation of an
Ada compiler to handle an interrupt (although since c++ doesn't have a builit
in ability to handle interrupt, it will have to be done partially outside of
the language).  But, if they are both able to answer to interrupt within the
required maximum latency then everything is peachy with both implementations! 
And we all know which one it is easier to write code in....
