RE: copying complex data structures

[West, William M]

use Storable;
$arrayref_one = dclone( $arrayref_two );



aha



thanks :)

it's those details that make a program so much easier to make..

i noticed another poster asking about reference notations- i think that this

and Object Oriented programming have given me the most headaches on a 
conceptual level.  

while i've gotten a handle on references (i hope) tha OO stuff still gets to
me *laugh*


again thanks,
willy

the following works fine:

foreach my $a (0..$what){
foreach my $b (0..$why){
$arrayref_one-[$a]-[$b] = $arrayref_two-[$a]-[$b];
}
}
it would be nice to have something to copy complex data structures that
isn't going to be a code maintenance headache-  the above is dependent
on the data structure being a 2 dimensional array of particular size.
i don't want that restriction.
any help would be apreciated :)
From the Perl Cookbook (2nd Edition), recipe 11.12:

use Storable;
$arrayref_one = dclone( $arrayref_two );

Try clone method of Storable module from CPAN.
There is also Clone module out there.

HTH,

José.
