Sorry Richard but, being genetically a pedant, I have to disagree with you. The word motor means "something which creates motion" ( http://en.wikipedia.org/wiki/Motor). So an internal combustion engine, an electric motor, a rocket engine, four hamsters in a cage, are all motors. :-) __________________________________________ David C Brown 43 Bings Road Whaley Bridge High Peak Phone: 01663 733236 Derbyshire eMail: dcb.home@gmail.com SK23 7ND web: www.bings-knowle.co.uk/dcb --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
