You can use break to get out of a while loop without exiting the entire script.
Use function when you do some tasks many times.
By the way, here is a sample of your code with some little improvment
If we want to exit, there already is a choice in the menu, so .... the following lines are useless (and even bad for the workflow of query)

tk::menu::item
Menu::Item(3) User Contributed Perl Documentation Menu::Item(3)NAME
Tk::Menu::Item - Base class for Menu items
SYNOPSIS
require Tk::Menu::Item;
my $but = $menu->Button(...);
$but->configure(...);
my $what = $but->cget();
package Whatever;
require Tk::Menu::Item;
@ISA = qw(Tk::Menu::Item);
sub PreInit
{
my ($class,$menu,$info) = @_;
$info->{'-xxxxx'} = ...
my $y = delete $info->{'-yyyy'};
}
DESCRIPTION
Tk::Menu::Item is the base class from which Tk::Menu::Button, Tk::Menu::Cascade, Tk::Menu::Radiobutton and Tk::Menu::Checkbutton are
derived. There is also a Tk::Menu::Separator.
Constructors are declared so that $menu->Button(...) etc. do what you would expect.
The "-label" option is pre-processed allowing ~ to be prefixed to the character to derive a "-underline" value. Thus
$menu->Button(-label => 'Goto ~Home',...)
is equivalent to
$menu->Button(-label => 'Goto Home', -underline => 6, ...)
The "Cascade" menu item creates a sub-menu and accepts these options:
-menuitems
A list of items for the sub-menu. Within this list (which is also accepted by Menu and Menubutton) the first two elements of each item
should be the "constructor" name and the label:
-menuitems => [
[Button => '~Quit', -command => [destroy => $mw]],
[Checkbutton => '~Oil', -variable => $oil],
]
-postcommand
A callback to be invoked before posting the menu.
-tearoff
Specifies whether sub-menu can be torn-off or not.
-menuvar
Scalar reference that will be set to the newly-created sub-menu.
The returned object is currently a blessed reference to an array of two items: the containing Menu and the 'label'. Methods "configure"
and "cget" are mapped onto underlying "entryconfigure" and "entrycget".
The main purpose of the OO interface is to allow derived item classes to be defined which pre-set the options used to create a more basic
item.
BUGS
This OO interface is very new. Using the label as the "key" is a problem for separaror items which don't have one. The alternative would be
to use an index into the menu but that is a problem if items are deleted (or inserted other than at the end).
There should probably be a PostInit entry point too, or a more widget like defered 'configure'.
