TApplication (with instance Application) that is available in every Lazarus program.

Unlike forms, and components on the forms a (single) instance of TApplication is created before any user line of code. In a .lpr file (a pascal file containing the keyword 'program' ) the Application-variable is used to create the applications form(s):

program pMyTest;
uses
  Forms, uMyForm

{$R *.res}

begin
  Application.Initialize();
  Application.CreateForm( TMyForm, MyForm );
  Application.Run();
end.

TMyForm is assumed a descendant of TForm and defined in uMyForm.pas
