["Dimitris Tsokakis" <TSOKAKIS@xxxx>]

The following formula gives the first and the last 
trading
day of a week.
As for the last week, everyday is the last 
day.

Sinatra

Pablo Picasso, after a<FONT face=Arial

left the rest of the painting for 
tomorrow
and a tiny note in a corner about tomorrow´s 
scedule.
A 3 years little girl in NY is still waiting for 
her daddy.
Last night he said "I´ll be there 
tomorrow".
And so on...)
