I have checked out the Data::Dumper and indeed it allows to dump a hash table and it is slightly in a different structure then the dumpvalue does but I could not find how to read back a dumped file. Like dumpvalue it only goes in one direction.

use Data::Dumper;
open (STDOUT, ">whatever.dat");
print Dumper(%flexlm);
close STDOUT;

I could not find how to read back a dumped file

Like so

use Data::Dumper;

my %hash = qw( foo one bar two baz three );

open  DATA, ">whatever.dat";
print DATA Dumper(\%hash);
close DATA;

my %hash2 = %{ do "whatever.dat" };
print Dumper(\%hash2);

__output__

$VAR1 = {
          'foo' => 'one',
          'baz' => 'three',
          'bar' => 'two'
        };

For more info see the ever-magical do() function.

Once you have read it in from the file and stored in a scalar, just do

my $ref = eval $data;

I always understood that you could eval the output of Data::Dumper to get the original variable structure back.

Reading the outputfile into a scalar variable and eval-ing this scalar should to the trick.
