    pin2 := foreach( pin1,
      bodypin1 := bodypin( pin1 ) AND
      inout( bodypin1 ) AND                                
      sName1 := concat_str( name(bodypin1) + "has the BIDIRECTIONAL property\n" ) AND
      append( linorout, sName1 )
    ) AND
    
    sName2 := name(pin2)
    Message(info, pin2, "?sName2", "\nGot the Pin which has the BIDIRECTIONAL property:\n\t?linorout");
