Hi David,

You can use lindex (Click here) to retrieve individual elements of the list. If you're trying to create a list of IP addresses, it would be more efficient to use a datagroup of type 'address' and use the matchclass command (Click here) to check if an IP address/subnet is part of the datagroup. 

 
 when RULE_INIT { 
  
 log local0. "\$::aol: $::aol" 
 log local0. "\[lindex \$::aol 0\]: [lindex $::aol 0]" 
 }

Rule : $::aol: {64.12.96.0/19} {149.174.160.0/20} {152.163.240.0/21} {152.163.248.0/22} {152.163.252.0/23} {152.163.96.0/22} {152.163.100.0/23} {195.93.32.0/22} {195.93.48.0/22} {195.93.64.0/19} {195.93.96.0/19} {195.93.16.0/20} {198.81.0.0/22} {198.81.16.0/20} {198.81.8.0/23} {202.67.64.128/25} {205.188.192.0/20} {205.188.208.0/23} {205.188.112.0/20} {205.188.146.144/30} {207.200.112.0/21}

Rule : [lindex $::aol 0]: 64.12.96.0/19
