You can open a file for output as: 
  open OUT, ">output.txt" or die "Can't open file\n";
  print OUT foo
  close OUT

and you can read as: 
  open IN, "output" or die "Can't open file\n";
  while(<IN>) { 
    # do something with $_
  }
  close IN;

Don't know if this is exactly what you want.

    You forgot semicolons after some statements. Anyway, in modern Perl it's written like that:
    {
    open my $fh, '>', 'filename.ext';
    print $fh 'foo';
    close $fh;
};

{
    open my $fh, '<', 'filename.ext';
    while (<$fh>) {
        # $_
    };
    close $fh;
};
