    tmac/an.tmac: Make code more accessible.
    
    * tmac/an.tmac (IP): Make code more accessible by using a Boolean
      operator rather than an arithmetic one (assembly language programmers
      are comfortable with the interchangeability of subtraction and
      comparison, but not everyone is).
    
    Also fix a misleading comment.
