So I'm getting an error saying two of my variables are unintilized when I initilize them at the beginning. Also advice for adding a use for a module. I tried lib '/Desktop/perl/final/ where I have it stored, but it didn't work. this is the code. 
 #!/usr/bin/perl -w
use strict;
#use beginperlforbioinfo;
my $annotation = '';
my $dna = '';
my $record='';
my $filename = "record.gb";
my $save_input_separator = $/;

unless (open(GBFILE, $filename))
{
    print "Cannot open Genbank file ";
    exit;
}
#use the input seperator //\n to read a entire file to scalar
$/ = "//\n";
$record= <GBFILE>;
#print $record;
#always to remember to reset the file input seperator
$/= $save_input_separator;
#to seperate the annotation from sequence
($annotation, $dna) = ($record =~ /^(LOCUS.*ORIGIN\s*\n)(.*)\/\/\n/s);
print "$annotation, $dna\n";

not sure how to make the module work and why I'm getting "Use of uninitialized value $annotation in print at parse.pl line 28, <GBFILE> line 1. Use of uninitialized value $dna in print at parse.pl line 28, <GBFILE> line 1. " errors.
