start with a sorted list
sort(aList)
then use something like
on deletedups aList
retlist=[]
cnt=count(aList)
repeat with i=1 to cnt
if not (inList(aList[i],retList)) then
add(retList,aList[i])
end if
end repeat
return retList
end
on inlist aItem, alist
cnt=count(alist)
isinlist=0
repeat with i=1 to cnt
if aname=alist[i] then
isinlist=1
exit repeat
else if aItem< alist[i] then
exit repeat
end if
end repeat
return isinlist
end
