How do I reference array using variable?

RouterOS Scripting

Thanks, I assumed as much and worked around this limitation by using nested arrays (similar to a hash table). For those that are interested herewith a post with a functional script:
http://forum.mikrotik.com/t/automating-address-list-maintenance-manrs-compliance/115375/1

Herewith sample array definition:

:local ifs { 
  {"filter-external"; 1; 1; {}; {}};
  {"filter-external-src"; 1; 0; {}; {}};
  {"filter-peer1-vlan645"; 1; 1; {205.37.17.206}; {}};
  {"filter-peer2-vlan417"; 1; 1; {205.19.28.105}; {}};
  {"filter-ixp1"; 1; 1; {205.60.8.156; 10.20.200.0/22}; {}};
  {"filter-upstream1-vlan143"; 1; 1; {205.22.33.34}; {}};
  {"filter-upstream2-vlan480"; 1; 1; {205.25.155.42}; {}};
  {"filter-upstream3-vlan85"; 1; 1; {205.79.22.66}; {}};
  {"filter-upstream4-vlan782"; 1; 1; {205.242.227.65}; {}};
};

Then when working with the information in the array:

:foreach if in=$ifs do={
  :local name ($if->0);
  :local prefixes ($if->3);	# load manual prefixes array as '$prefixes'
  # ie. when name = 'filter-ixp1' then '$prefixes->1' = 10.20.200.0/22
...
}
