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.
