I've heard some rumors about a C interpreters called Saber. Does anyone
know where I can get more information about it? Any information about
commercially available, or even free, C interpreters would be
appreciated.
Thanks

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@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.
