Mike.  Sorry about the ‘r’.  You’ll note ‘r’ is right next to the ‘e’ on the QWERTY keyboard.  I'm afraid I've done that a few times recently.  I’ve spent another hour looking at Art 292, and I can see no direct corelation between the two diagrams.  There’s too much upside down and back to front about the situations.  I even tried going over the diagram in ink and turning the paper upside down to get a mirror image, but I still couldn’t make it work.  I think there comes a time when you have to say it’s not the readers job to correct the authors poor instruction, poor technical proof reading, or possible errors in typesetting.  If you’ve got a method that does work, use that instead.  DaveP
