W528 Loop variable is not used in FOR-loop

  for I := 0 to FServices.Count - 1 do
    SumDeposit.Add(0);  //FI:W528

Its not working. Do I have to do anything else? There is nothing in the manual.
[FixInsight Internal] uDepositList.pas(186): I901 Useless comment "fi:w528" detected. No warnings or hints have been found at this line
Repair. That's right 

 for I := 0 to FServices.Count - 1 do //FI:W528

Right, FI:xxx comment should be placed exactly on a line where warning occurs
