Hi,

 Code:

 #+BABEL: :cache yes :tangle yes :noweb yes

 #+NAME: top_block
 #+begin_src perl :tangle test.pl :noweb tangle

From (info (org) padline):
 14.8.2.10 ‘:padline’
 
 
 Control in insertion of padding lines around code block bodies in
 tangled code files.  The default value is ‘yes’ which results in
 insertion of newlines before and after each tangled code block.  The
 following arguments are accepted.
 
• ‘yes’ Insert newlines before and after each code block body in
  tangled code files.
• ‘no’ Do not insert any newline padding in tangled output.

You can use the following block declaration:
#+begin_src perl :tangle test.pl :noweb tangle :padline no

   #!/usr/bin/perl

   use strict;
   use warnings;

   open(my $fh, , test.txt)
   or die cannot open  file name: $!;
   output-all
   close($fh);
 #+end_src

 #+NAME: output-all
 #+begin_src perl
   while (my $line = $fh) {
   print $line;
   }
 #+end_src

 Outputs a perl file, where the 1-st line is blank. What should I do to remove 
 it?
