std::ostream& operator<< (std::ostream& os, const PhoneNumber& pn){

std::locale loc = os.getloc (); // 1

os << ppFacet.put(pn._cntryName,

pn._areaCode, pn._extension); // 3

</PRE></UL>

<TABLE CELLPADDING="3">

<TR VALIGN="top"><TD><SAMP>//2</SAMP></TD><TD>uses the locale's phone number facet object,
