The 
binary
Binary JOOS compilers for Solaris, Irix, and Linux systems are
available. To use them, you must follow the
general guidelines for setting up
the JOOS/Java environment.
The compiler may be used for experiments and can answer many detailed questions about the correct semantics of the JOOS language. The compiler is an A+ version, which means that:
- it allows C-style comments;
- it allows increments and for-loops as syntactic sugar;
- it computes the correct stack limits; and
- it implements 40 interesting peephole patterns.
