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"]
