Re^2: Creating members of hash of hashes parallelly

[utku]

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!

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?

[utku]

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.
