The phone system was/is one of Peter Honeyman's pet examples of what *isn`t* an absolute address. E.g. my work number (203) 432-1254. Within Yale, you only have to dial the last 5 numbers (the seven digit version won't work). From many offices, you'll have to dial "9" to get an outside line (i.e. the number is relative to "the outside world"). From many countries, you'll have to dial a country code followed by the number (the number is relative to the US phone system). And so on .... -- Ed Anselmo anselmo-ed@cs.yale.edu {harvard,decvax}!yale!anselmo-ed
