consistently throughout this manual: 
 -  Examples of commands entered at the terminal are in typewriter font:
         TFFILTER 5, as are messages from the computer;
 
 -  Angle brackets denote parameter values or character strings:
         <angle>;
 
 -  Square brackets denote optional input  e.g.  [x,y]; all other 
        parameters are obligatory;
