Is there a way to find duplicate items in a list?
aList = ["mary", "mary", "john", "steve", "john", "mary"]
How can I find how many mary and john are in the list and its location
without doing a lot of repeats?
Thanks,

No need to sort version:
on deletedups aList
retlist=[]
repeat while aList.count()
aItem = aList[1]
add(retList,aList[1])
aList.deleteAt(1)
repeat while aList.getOne(aItem)
aList.deleteOne(aItem)
end repeat
end repeat
return retList
end

Another variation on a theme...
on removeDuplicates vlist
sort vlist
repeat with i = count(vlist) down to 2
if vlist[i] = vlist[i-1] then vlist.deleteAt(i)
end repeat
end
