Here's a simple FSM implementation. Each subroutine returns the next 'state' (just a subroutine name) to pass control to. To exit, return undef. 
my $state = "start";
while (my $next = $state->()) {
  $state = $next;
}

sub start {
  ...get input...
  if (/1/) { return "menu_1" }
  elsif (/2/) { return "menu_2" }
  ...
}

sub menu_1 {
  ...
}

sub menu_2 {
 ...
}
