(This seems to keep coming up....)

Yes, Saber-C is an (excellent!) C interpreter.  Lots of fancy
debugging features are available, as is the ability to execute C
statements interactively.  (In version 1.x of Saber-C, all the
commands were issued in C syntax -- including preprocessor commands.
Version 2.0, in beta test, also accepts shell-style input.)

I believe Saber-C accepts either ANSI or K&R C.  It catches bad memory
references (free()'d memory, type mismatching on retrieval, bounds
checking), unused variables, missing declarations of functions
(sometimes annoying but generally correct, strictly speaking -- don't
you sometimes forget to declare malloc or include <string.h>?), link
against compiled code (though this naturally reduces the debugging
capabilities), and, of course, run your program.

The manuals I've got in front of me don't appear to list the machine
types it runs on.  I do know that it runs on the vax and the IBM
RT/PC; these are the only machine types Athena has at this point, so I
wouldn't know about any others.

The address to get more info is saber at harvard.harvard.edu.  It's also
the address for bug reports and questions.  Although Saber-C isn't
completely without bugs (and the occasional annoying misfeature), the
people I've dealt with regarding it have been most helpful in tracking
things down.

I would heartily recommend it.
