in reply to alphabet counting

You are printing inside your loop.

You want to accumulate your values and then only print them after you are done.

As an aside, it would be more perlish if you were using a hash to accumulate your values... you could change all your ifs to a single line.

And it's probably not a good idea to call the filehandle IN when you are using it for output.

      You could guess that any such problems could be easily resolved... did you try something like this: 

      print "$k => $h{$k}\n" for my $k (sort keys %h);

        Hmm...

        my %h = ( a => 1, b => 2, c => 3 );
print "$k => $h{$k}\n" for my $k (sort keys %h);

        Maybe you meant something like:

        print "$_ => $h{$_}\n" for sort keys %h;

        Or the (no doubt) more newbie-friendly: 

        for my $k ( sort keys %h ) {
  print "$k => $h{$k}\n";
};
