If it's not clear we can certainly change it. I looked at the manual page. It says: "is JIT compilation available in this session (see Chapter 31)? Returns false if jit is set to false." Maybe this would be better? "returns true if jit is enabled and JIT compilation is available in this session (see Chapter 31)." Open to other suggestions. David
