Hope not. Would no more RJ mean no more RF, YJ, or CJ either?

If your shopping basket had been designed by a C programmer, its initial state would be the state just before the zeroth item was inserted. That suggests that initially the basket contains -1 items. -- Peter Moylan, Newcastle, NSW, Australia. http://www.pmoylan.org For an e-mail address, see my web page.

Only after I make a decision about whether to buy Mallomars does the state (with respect to Mallomars) change to 0 or 1. The initial state is never -1. Don't be confused by the practical consideration of not being able to distinguish between Null and 0. In databases, there is no ambiguity at all, since anything added to a Null results in Null, anything compared to a Null is false. The same does NOT hold for values of 0. 99 bottles of beer on the wall, 99 bottles of beer! If Null bottles should happen to fall, Null bottles of beer on the wall! > > -- > Peter Moylan, Newcastle, NSW, Australia. http://www.pmoylan.org > For an e-mail address, see my web page.

I believe he did ask Peter and the others to keep on spreading the word, but I have seen no mention of churches, priests, buildings, vestments or choir boys in the New Testament. -- Rob Bannister |
