Hi All,
I needed to slightly alter the behaviour of a module I use in Perl.
In order to see the data structure I used Data:Dumper to get an output so I
could find the piece that I required for the change of logic.
To my shock and horror it gave me this:
$VAR1 = bless( do{\(my $o = '139790129395

Data::Dumper can be configured through the use of its package
variables (or methods if you are using the OO version).

You need to do:

my @keys = sort { $a cmp $b } keys(%hash);
[/code]
Is it causing a memory overflow?

Dump the data structure for printing.
It's useful for checking the complex data strucure of Perl.
For example,

You might like the results better using an array reference.

Or you could avoid the extra array with the anonymous array

Hi all,
I want to store some complex data. My first solution made use of Storable, which
worked just fine. Now I learned that neither Storable nor MLDBM are available on the
machine I want to use the program on (and they cannot be made available).
So I retreat to the core and use Data::Dumper
since the
parameter-passing process need not change it in any way. Then the called
function can use it to access the original, intact structure:
Greetings! C:\>perl -w
use Data::Dumper;
