From analyzing your question I'd assume that you try to handle the content of each file as a string for itself (no concatenation).

About one month ago you asked almost the same question w/different wording.

Please do give us some more words of "problem description" next time ;-)

(My interpretation of your question follows:)

my ($filename1, $filename2) = qw( adaykin1.txt adaykin2.txt );
my @string;

for my $fn ($filename1, $filename2) {        # iterate over given file
+names
 open my $fh, '<', $fn or die "$fn - $!";    # open each file
 local $/; push @string, <$fh>               # read it into one string
}
# 
print $string[0]; # first file as one big string
print $string[1]; # second file as one big string
