Example code : Showing maximum and minimum LongWord values
// Full Unit code.
// -----------------------------------------------------------
// You must store this code in a unit called Unit1 with a form
// called Form1 that has an OnCreate event called FormCreate.
 
unit Unit1;
 
interface
 
uses
  // The System unit does not need to be defined
  SysUtils,
  Forms, Dialogs;
 
type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  end;
 
var
  
Form1: TForm1;
 
implementation
{$R *.dfm} // Include form definitions
 
procedure TForm1.FormCreate(Sender: TObject);

var
  min, max : LongWord;
begin
  // Set the minimum and maximum values of this data type
  min := Low(LongWord);
  max := High(LongWord);
  ShowMessage('Min long word value = '+IntToStr(min));
  ShowMessage('Max long word value = '+IntToStr(max));
end;

 
end.
