my $s = ;
my $t = ;
conc ( $s , $t );
sub conc {
my $str = $_[0].$_[1];
print $str;
}
Why? It works allright only after add an extra line at the top, that is
sub conc;
its become just like C

Your code works just fine for me (no errors).
Actually, that was just an example to explain my problem. I am facing
this problem when i use Tk. Any subroutine associated with the
-command option of a button widget.
use Tk;
my $mw = MainWindow-new;
my $b = $mw-Button(-text='hello',-command=sub { welcome })-pack;
my $l =
Because if define it, it says 'Global variable $l needs...' what do
i do? Actually, i am not happy nor sad that the subroutine needed a
declaration before use.. I'm using ActivePerl 5.8.8 on Windows XP
