Apologies for the poor formatting on my previous post and thank you all for your input. So I am creating arrays to store the checksum of files and I do this twice as I have 2 directories. I am then trying to compare the arrays using the last bit of code. This is when the arrays go out of scope:

for my $entry(@files1) {
my $readfile = "$dir1\\$entry";
#print "$readfile\n";

if (-e $readfile && -r $readfile){
open (FILE, $readfile) or die "Error opening: '$readfile': $!";
binmode(FILE);

my $md5 = Digest::MD5->new;
$md5-> b64digest;

while (<FILE>) {
$md5->add($_);
}

my @digest1 = $md5->b64digest;
#print "@digest1\n";#This array will go out of scope
print "$readfile: @digest1\n";
}
close (FILE);
}        print "\n";

#2nd directory
for my $entry(@files2) {
my $readfile = "$dir2\\$entry";
#print "$readfile\n";

if (-e $readfile && -r $readfile){
open (FILE, $readfile) or die "Error opening: '$readfile': $!";
binmode(FILE);

my $md5 = Digest::MD5->new;
$md5-> b64digest;

while (<FILE>) {
$md5->add($_);
}
my @digest2 = $md5->b64digest;#This array will go out of scope
print "$readfile: @digest2\n";
}
close (FILE);
    }

#compare directories
my $equals = 1;
foreach (my $i = 0; $i <@digest1; $i++) {
    if (my $digest1[$i] ne my $digest2[$i]){
$equals = 0;
}
else {
$equals = 1;
     }
print "$equals";
}
