In several countries they are in the process of changing the number of
digits in a phone number -- from four to five, five to six, or six to seven.
Since we're running out of area codes, I started to wonder how much
it would cost to make telephone numbers eight digits long.  For ease of
changeover assume a flag day on which everyone has, say, a zero appended
to their current phone number.  How much would it cost the phone companies
and how much would it cost everybody to change their COBOL programs?

any guesses?
