Function: list ListXorY(list lx, list ly);

Join two lists to make one new combined list, while also eliminating any resulting duplicates in the new list.

<lsl> list ListXorY(list lx, list ly){ // add the lists eliminating duplicates

   list lz = []; integer x;
   for (x = 0; x < llGetListLength(ly); ++x){
       if ((integer)~llListFindList(lx,llList2List(ly,x,x))){
           ;
       }
       else {
           lz = lz + llList2List(ly,x,x);
       }
   }
   return lx + lz;

} </lsl>


Example:

<lsl> list l1 = ["a","b","c","d"]; list l2 = ["a","1","b","2","c","3"];

default{

  state_entry() {
     llSay(0, "The new combined list is: " + llList2CSV(ListXorY(l1,l2)) );
     //will say: a, b, c, d, 1, 2, 3
  }

} </lsl>
