HoHoH solution has the drawback that the interpreter generates an initialization error during initialization of indices.
How so? Can you show us what you mean?

    Sorry, it was a mistake of my code.

    For HoHoH solution, if I use my own dump routine instead of Dumper:

    foreach $path ( keys %db_hash ) {
    print "List for $path...\n";
    foreach $index ( keys %{ $db_hash{$path} } ) {
        print "END: ", $db_hash{$path}{$index}{END}, "\n";
    }
 }

    then following comes to stdout: 
    Use of uninitialized value in print at ./utk.pl line 66, <FH> line 246
+99.
Use of uninitialized value in print at ./utk.pl line 66, <FH> line 246
+99.

    [download]
    line 66 is the line of "print END" routine. In this case, 
    $db_hash{$path}{$index}{END}

    [download]
    tries to access 
    $db_hash{$path}{'index'}{END}

    ... which does not exist anyway. It was a mistake that I did not use the Dumper.
