In Roger's link, Dijkstra is referring to "the end of the first page" rather 
than "the end of the zeroeth page", so Dijkstra was not taking his own 
medicine. A solution to the problem is to distinguish between the ordinal 
numbers (first, second, and so on) and cardinal numbers (zero, one, and so on). 
The first ordinal number is "first", and the first cardinal number is "zero". 
Cardinal number are for indexing, not for counting. 
Thanks. Bo.
