Hi all

I have created a program which i use for making MSN names reverse [i.e. Frank becomes knarF] and now I want it to also randomize upper and lowercase characters to make it even less readable, so that Frank becomes kNaRf for instance, I do use spaces and lines from lyrics by the way, can anyone help?

Thank you


The code is:
======
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, strutils, StdCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Edit2: TEdit;
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private

    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  edit1.Text:= '';
  edit2.Text:= '';
end;

function Reverse(InStr: string): string;
begin
 result := '';
 if Length(InStr) = 0 then
  exit;
 if InStr[1] = '-' then
 begin
  result := '-';
  Delete(InStr, 1, 1);
 end;
 result := LowerCase(result + ReverseString(InStr));
end;

procedure TForm1.Button1Click(Sender: TObject);
var
line1, line2: string;
begin
line1:= Reverse (edit1.Text);
line1:= ReverseString(edit1.Text);
edit2.Text := line1;
end;



end.

see this example:
function MixCase(InStr: string): string;
var i: integer;
begin
 Randomize();
 for i := 1 to Length(InStr) do
  if Random(2) = 1 then
   result := result + LowerCase(InStr[i])
  else
   result := result + UpperCase(InStr[i]);
end;
