Table 1. How JES2 resolves destinations -- example 3
1 Destination Specified at NODE 1	2 DESTID Specified at NODE 1	3 Destination Sent (NJE Header)	4 DESTID Specified at NODE 2	5 Destination Resolved
NODE2.BILL	DESTID(BILL) DEST=NODE2.JOHN	NODE2 JOHN	DESTID(JOHN) DEST=NODE3.U5	NODE3.U5

1 The destination specified on a /*ROUTE PRT JES2 control statement, NODE2.BILL, means: Send this SYSOUT data set to destination BILL at Node 2.
2 JES2 determines whether Node 1 has a definition for destination BILL. It finds a DESTID(BILL) initialization statement definition. Comparing the first-level identifiers and finding that they match (NODE2 specified on the /*ROUTE statement and the DEST= parameter specifies NODE2), JES2 uses the second-level destination (JOHN).
3 JES2 puts the destination of JOHN at NODE2 into the NJE header and sends the SYSOUT to Node 2.
4 At Node 2, JES2 takes the incoming destination of JOHN and determines if it is defined as a destination identifier. There is a DESTID(JOHN) initialization statement. Its DEST= parameter specifies NODE3.U5. Because this is the specification defined at Node 2 (the destination node), JES2 uses it.
5 The resolved destination is U5 (special local routing 5) at Node 3.
