The AT option is used to explicitly direct a command to a user ID on a particular RRSF node. Although explicit command direction using the AT option and automatic command direction are two distinct forms of command direction, they can both occur when a command is issued within an RRSF network, as shown in the following examples.

1. Suppose:
   • NODE1, NODE2, and NODE3 are RRSF nodes that are operative targets of each other.
   • NODE2 and NODE3 have automatic command direction activated between them with the following RRSFDATA class profiles:
     • On NODE2: AUTODIRECT.NODE3.* with UACC(READ)
     • On NODE3: AUTODIRECT.NODE2.* with UACC(READ)
   • CHARLIE1 on NODE1 has a peer user ID association with CHARLIE2 on NODE2.
   • CHARLIE2 exists on NODE2 and NODE3, but with no user ID association between nodes.
2. CHARLIE1 on NODE1 issues the following command:

   ADDUSER PREMA AT(NODE2.CHARLIE2)

3. Because the AT option was specified, the command is explicitly directed to NODE2.CHARLIE2.
4. At NODE2, the ADDUSER PREMA command runs under the authority of CHARLIE2.
5. After the ADDUSER PREMA command runs successfully (under the authority of CHARLIE2 at NODE2), it is automatically directed to NODE3.CHARLIE2.
