200	Function ID
0.0	Forced Delay
10.0	Energy

• list	dest
• list	src

start supports negative indexes.

Specification

Index	Positive	Negative
First	0	-length
Last	length - 1	-1

Indexes

• Positive indexes count from the beginning, the first item being indexed as 0, the last as (length - 1).

Examples

<lsl> list numbers = [3, "three", 2, "two", 1, "one"]; default {

   state_entry()
   {
       llOwnerSay(llDumpList2String(numbers, ","));
       // Object: 3,three,2,two,1,one
       integer index = llListFindList(numbers, [2]);
       if (index != -1)
       {
           numbers = llListInsertList(numbers, [2.5, "two and a half"], index);
           llOwnerSay(llDumpList2String(numbers, ","));
           // Object: 3,three,2.500000,two and a half,2,two,1,one
       }
   }

}

</lsl>

Notes

Bear in mind that the source list will remain unchanged. Instead, a new list will be produced. So, it's important that you capture this with a variable (unless you are acting directly on the results.)

Tip! To insert something at the start of a list, you can just add the two lists (putting the list with the new item(s) first)

<lsl> list oldList = ["B", "C", "D"]; list newItem = ["A"]; list newlist = newItem + oldList; </lsl>
