I'm trying to improve my programming style and have read perlstyle and will probably pick up the book Code Complete. I have, however, a question about organizing subroutines. What if I have a program that has all of it's logical functions broken up into subroutines and they're not passing each other data. This would work:

func1();
func2();
func3();

sub func1 {
}
sub func2{
} 
sub func3{
}

Or would this be better:

func1();

sub func1{
  func2();
}
sub func2{
  func3();
}

I'm just not sure what's the best programming practice even if several options will work. Certainly not one big function with all global variables. TIA...Kevin
