That's why I specified that the change of nature relates to the rows 
"that would otherwise have been produced". Perhaps I should have 
referred to a single changing the order of the progression of the 
positive and negative rows. In PB Doubles the 145 bob does not alter the 
succession of +ve and -ve rows that occurs at a plain lead.  In the case 
of the Harrington Bob Doubles the 145 call does do so.
