Thank you for the clarification. Is there a formal specification somewhere of how the DIV operator exactly works? I read quite a lot of stuff about Oberon but didn't find an indication so far that "-1 DIV 16 = -1". Can you give me a hint please where I can find a complete specification, a value table or at least a reference implementation?
