Another other option, is to put parenthesis after the subroutine name
where the sub is called:

MainMenu();

This will force the compiler to recognize it as a subroutine call.
(The times where this is not useful is when you want to give the
subroutine to get the same arguments as the calling sub. Giving an
empty argument list clears out @_.)
