I should give an example of what I'm trying to do. The NewTrackList procedure is 
supposed to create a list of 14 numbers from 1 to 14, with no numbers repeated. The 
list is supposed to be random, that is, a different sequence of numbers is created 
every time the procedure runs.

Answer:
1   
2   procedure NewTrackList;
3   var
4     TrackNumbersList: array[1..14] of Integer;
5     I, II: Integer;
6     SameTracks: Boolean;
7     S: string;
8   begin
9     for I := 1 to 14 do
10      TrackNumbersList[I] := 0;
11    for I := 1 to 14 do
12    begin
13      TrackNumbersList[I] := Random(14) + 1;
14      repeat
15        SameTracks := False;
16        for II := 1 to I - 1 do
17        begin
18          if I = 1 then
19            Break;
20          if TrackNumbersList[I] = TrackNumbersList[II] then
21          begin
22            SameTracks := True;
23            TrackNumbersList[I] := Random(14) + 1;
24            Break;
25          end;
26        end;
27      until
28        not SameTracks;
29    end;
30    S := '';
31    for I := 1 to 14 do
32      S := S + '  ' + IntToStr(TrackNumbersList[I]);
33    Form1.Label1.Caption := S;
34  end;
35  
36  procedure TTunesMain.FormCreate(Sender: TObject);
37  begin
38    Randomize;
39    NewTrackList;
40  end;


S is a local variable of type String. I obviously added a TLabel to the form, as well.
