Autonomous systems will be assigned 16-bit identification numbers (in much the same ways as network and protocol numbers are now assigned), and every EGP message header contains one word for this number.
Was that a 36-bit word? --lyndon I think 3B2 code deserves its own place in hell. Poring over the ESS#5 code, someone found that there were lots of strcmp(p, "f(") == 0 checks (I may have gotten the exact string wrong but it's close). It took us a while to figure out why. Apparently, location 0 on the 3b had the 3 bytes 'f' '(' '\0', someone noticed that when programs blew up they were pointing to "f(", and the worlds most amazing kludge for detecting nil pointers was born. -- Dave Presotto
