Unfortunately for readers, the above statements are not true. (This was not intended, I feel sure ...) This is one example why I am a proponent of runnable code, and explanations with pictures. If a poster actually runs the exact code they post before posting (and looks at the results) then such errors are usually caught. This is also a good example of why I favor tutorial posting in a forum or blog format. In such a format, any error may be edited and corrected as necessary. In a message list, by contrast, such an error can only be pointed out in a later message, which is of little help to people who have taken the advice of the initial, incorrect message.
