function flagDupes tList
put tList into scratchList
repeat for each line t in tList
if t is among the lines of scratchList or \
freqArray[t] > 0 then
add 1 to freqArray[t]
put cr & t & "-" & freqArray[t] after outputList
else
put cr & t after outputList
end if
delete line 1 of scratchList
end repeat
delete char 1 of outputList
return outputList
end flagDupes
I *think* this should be fast with large lists.
