Function: list ListUnique(list lAll;

Given a list of elements, strips out duplicates in that list.

<lsl> list ListUnique( list lAll ) {

   integer i;
   list lFiltered = llList2List(lAll, 0, 0);
   integer iAll = llGetListLength( lAll );
   for (i = 1; i < iAll; i++) {
       if ( llListFindList(lFiltered, llList2List(lAll, i, i) ) == -1 ) {
           lFiltered += llList2List(lAll, i, i);
       }
   }
   return lFiltered;

}

</lsl>


Example:

list mylist = ListUnique(["A", "A", "B", "C", "C", "B"])

would return the list:

["A", "B", "C"]
