in reply to Read the Dumper data back to a hash.

Don't dump the hash as

print Dumper %hash;

But rather use

print Dumper \%hash; # ^

Then you can simply use eval to obtain a hash reference, so for example

my %copied_hash = %{ eval $string };

    What is $string in eval $string? Is it the file handle?

      The string returned by Dumper.

        Sorry, but i could not understand.
        Please tell me how does Dumper return the string..
