Debug code snuck in. That should be:

function sumPermute S,T
   repeat
      put offset(",",line 1 of S) into F
      if F = 0 then exit repeat
      put empty into newS
      repeat with i = 1 to 3
         put char i of "+- " into C
         repeat for each line L in S
            put C into char F of L
            put L & cr after newS
         end repeat
      end repeat
      put char 1 to -2 of newS into S
   end repeat
   repeat for each line L in S
      replace space with empty in L
      if value(L) = T then put L & cr after R
   end repeat
   return R
end sumPermute
