Here is the exact program:
===========
#!c:/perl/bin/perl.exe -w
use threads;
use strict;
my $thread1 = threads->create ( \&Test, "1" );
my $thread2 = threads->create ( \&Test, "2" );
$thread1->join;
$thread2->join;
exit;
sub Test {
my $test = shift;
print "\nHello World! - " . $test;
return $test;
}
