Sure ...

let's take an example where $abutton is a gtk button ,
$a its label , $bbutton if it exists a button from the
same button group .

...

#depending on the circumstances @args is either equal to
#($a) or ($a,$bbutton)
Make_Button($abutton,@args);

...

sub Make_Button {
my ($aa,@bb)=@_;
$aa = new Gtk::RadioButton(here must come either
                            $a
                            or $a,$bbutton);
}

#end of script

The syntax is very rigid , how do i manage to have the 
equivalent of  
$button = new Gtk::RadioButton($a, $bbutton);
within the sub , and starting from @bb

Sorry for the confusion , maybe it's confusing because i see
a problem where there's none ( but a mere
$aa = new Gtk::RadioButton(@bb) within the sub doesn't work 
so ...


P.S.: i pretty new , can you tell me where this message is
visible ? i have to pass through my home node to see it ...
