Another problem is that some of the string instructions on the
uVax-II are ``minicoded'':  the arguments are put in the appropriate
registers, then the CPU traps somewhere to let an assembly code
routine handle the work.  Examples are scanc and matchc, but, I
have been told, *not* movc3.

I have also been told that the code which implements these instructions
is nontrivial.  It is not on the 4.3 alpha tapes, and I doubt that
it will be included in the 4.3 distribution.
