Well if you are really concerned, write a custom datatype where you
store 2 digits of the telephone number in one byte. A nibble for
0-9+-/ und " " should be plenty (you would even have a c-like
string end marker :-) Of course you would need to write operators
for everything you want to do w/ it. IIRC, there were even plans
I read on the list to write such a datatype. Maybe you scan the
list archives first.
