Hello All, I am facing an issue while passing an open filehandle to a subroutine .The code goes something like below. 

my $in = "class.txt";
open F , $in or die;
my $line =<F>;
  while($line){
     if ($line =~ /xyz/){
                  SubOut(\*F); 
     }
     $line =<F> ; 
  }
close F;


sub SubOut{
   my $fh = shift;
   my $s_line = <$fh>;
   my @ref;
   push (\@ref, $s_line);
    while($s_line){
         print STDOUT $s_line;
         $s_line = <$fh>;
     }
}

When i execute this code , i end up losing the line that matches in the main program.How can i pass an open filehandle to a subroutine and store the line that matches in the main program.In the code above i am losing that line cause of my $s_line = <$fh>.
