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
