<lsl>list numbers = [1, 2, 3, 4, 5]; default {
state_entry()
{
integer index = llListFindList(numbers, [3]);
if (index != -1)
{
list three_four = llList2List(numbers, index, index + 1);

// Object: 3,4
}
}
}</lsl>
Useful Snippets
An easy way to see if an item exists in a list... <lsl>if(~llListFindList(myList, (list)item)) {//it exists
//This works because ~(-1) == 0 //It saves bytecode and is faster then doing != -1
}</lsl>
