Shouldn't that be print OUT Dumper (\%hash) Data dumper will name it $VAR1 or something like that. You can get it to name it the same as the original, but I think it'll still need to be a reference. Maybe: Data::Dumper->Dump([\%hash], [qw(hash)]); Will work (untested). Then if you really didn't want it as a reference: our ( $hash, %hash ); require "dumpfile.pl"; %hash = %$hash; But that would be silly. Really you should look at data serialization, and encode the data structure to YAML or JSON before writing to a file. That way it could potentially be read in a decoded by any number of languages.
