I have a  coverage analyzer for C which runs under VMS. It allows
full I/O from the program under test. The instrumentation overhead is
extremely low as the program communicates branch "Hits" to another
process which does the bean counting. It is written in Ada and would require
a re-write to run on anything other than VMS (uses CLD,LIB$TPARSE,QIOWs,HELP,
,etc). If anyone is wondering why we wrote the thing in Ada to do C it's
because the instructor, the editor of the OOP Journal and The Journal 
of Pacal Ada and Modula-2, wanted the instrumenter done for either
C or Modula-2 and we had a team with defense contractor who did not want
to relearn C or Modula-2 as an implementation language. 
	We also wanted to get away with writing as few lines of Ada as we
could so the VMS libraries were heavily used along with the 
Booch Components. It does a nice job and maintains statistics on the
code under test for the individual testcases as they are run. I can
make it available via FTP (soon) or a TK50.
