Thank you very much folks, you have enlightened the points I could not figure out.

Both solutions (HoAoH by robotics and japhy; HoHoH by liverpole) worked.
HoHoH solution has the drawback that the interpreter generates an initialization error during initialization of indices.

Thanks again for your ultra-fast answers!

    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.
      line 66 is the line of "print END" routine. In this case,
      $db_hash{$path}{$index}{END}
      tries to access
      $db_hash{$path}{'index'}{END}
      ... which does not exist anyway. It was a mistake that I did not use the Dumper.
