If it's `print "@array\n";` [download] for an array, it's `print "@{$ref}\n";` [download] or simply `print "@$ref\n";` [download] for an array ref. Dereferencing Syntax References Quick Reference	[reply] [d/l] [select]

It's a array ref not hash ref, if you get something like HASH(0xbb99fdx), then it's a hash ref. To get the value from the array ref, you need to dereference it, example like `my $test = [ "Hello", "PM" ]; #print $test, you will get array ref @array_deref = @{$test}; #dereferencing the array ref print"@array_deref\n";` [download]	[reply] [d/l]

You'll find the answer on line 42 of the documentation. If you show me some sample code that demonstrates the problem I might feel inclined to help a little more. True laziness is hard work	[reply]

To help you understand the underlying data structures that you have created, use the Data::Dumper module. An example follows, using a $test variable proposed elsewhere in this thread: `use strict; use warnings; use Data::Dumper; my $test = [ "Hello", "PM" ]; print (( Data::Dumper->new([ \$test ], [qw( test )]))->Dump); # or # my $dd = Data::Dumper->new([ \$test ], [qw( test )]); # print $dd->Dump;` [download]	[reply] [d/l]
