| Example code : Showing maximum and minimum byte 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 : Byte;
begin
// Set the minimum and maximum values of this data type
min := Low(Byte);
max := High(Byte);
ShowMessage('Min byte value = '+IntToStr(min));
ShowMessage('Max byte value = '+IntToStr(max));
end;
end.
