show capital guessed in four or less tries

This program needs to output the number of states which the user was able to guess the capital in four or less tries. If I leave it like this, then it doesn't work.  Here it is:

var state: string;
    capital : string;
    Statefile: text;
    tries: integer;
    guess: string;

procedure GETDATA (var localStatefile: text;
                   var localstate: string;
                   var localcapital: string);

   begin
      readln (localStatefile, localstate);
      readln (localStatefile, localcapital);
   end; {GETDATA}

procedure GUESS_CAPITAL (var tries: integer;
                         guess: string);

   begin{GUESS_CAPITAL}
     tries := 0;
     repeat
       tries := tries + 1;
       write ('Give capital of ', state, ' ' );
       readln (guess)
     until (guess = capital) or (tries = 4);
      if guess = capital then
        writeln ('Nice work.  You got it on try ', tries)
      else
          begin{until}
           writeln ('You did not get it in 4 tries or less');
           writeln ('The correct answer is ' , capital)
          end;{until}
   end; {GUESS_CAPITAL}

procedure GUESSES (var tries: integer);
   begin
     if tries <>4 then
       writeln ('You got these states in 4 or fewer tries ', state)
   end;{GUESSES}


begin {main}
     assign (Statefile, 'A:\state2.dat');
     reset (Statefile);
     while not seekeof (Statefile) do
       begin
         GETDATA (Statefile, state, capital);
         GUESS_CAPITAL (tries, guess);
         GUESSES (tries)
       end;
     close (Statefile)
end.
