Hello 1nickt,

I was experimenting with Data::Printer as an alternative way.

You can use it for example like:

use Data::Printer;
p %hash;

This why you could see the printing part. Hope is more clear now. :)

Update: Sample of code that I was experimenting, see below:

#!/usr/bin/perl
use strict;
use warnings;
use Data::Printer;

my %hash = ( ';LCBO - Prolactin precursor - Bovine' => "a sample seque
+nce in FASTA format
         MDSKGSSQKGSRLLLLLVVSNLLLCQGVVSTPVCPNGPGNCQVSLRDLFDRAVMVSHYIHD
+LSS
         EMFNEFDKRYAQGKGFITMALNSCHTSSLPTPEDKEQAQQTHHEVLMSLILGLLRSWNDPL

+DED
         ARYSAFYNLLHCLRRDSSKIDTYLKLLNCRIIYNNNC*" );

my $filename = 'output.txt';

open(my $fh, '>', $filename)
    or die "Could not open file '$filename' $!";

p(%hash, output => $fh);

close $fh
    or warn "Could not open file '$filename' $!";

print "Done\n";

__END__

$ perl test.pl
Done
$ cat output.txt
{
    ';LCBO - Prolactin precursor - Bovine'   "a sample sequence in FAS
