Hi, If you undef a var, or assign that var to something esle, then how does this happen? 
## the test script

use Report::testob;


my $testo;

$x=0;

while($x<10){


undef $testo;

$testo="ooof";

$testo=testob->new();


$testo->printblah();

$testo="yess";


$x++;

}


#####

# the "object"

package testob;


sub new {

    my $class=shift;
    my $self={@_};

    bless($self,$class);
    return $self;    
}


sub printblah{

 my $self=shift;

 $blah++;
$self->{blah}++;
print "blah is $blah \n";
print "self blah is ".$self->{blah}."\n";
}


1;

#####

# the output

blah is 1
self blah is 1
blah is 2
self blah is 1
blah is 3
self blah is 1
blah is 4
self blah is 1
blah is 5
self blah is 1
blah is 6
self blah is 1
blah is 7
self blah is 1
blah is 8
self blah is 1
blah is 9
self blah is 1
blah is 10
self blah is 1

## how does this happen? I thought that assigning $testob to a string or calling undef would remove any reference to the memory location of the object, but it is clear here that $blah in the "object" retains this as does $testob?? please enlighten me! thanks in advance.

In reply to Undef doesnt work?This has got me stumped by pike_uk
