See if this helps http://www.pm.org/groups/united_states_of_america.html > Would anyone mind explaining references to me like I was five years old? References are like pointers in C. References can be created to different data structures like scalars, arrays, hashes, subroutines etc. And they can be created using a back-slash (\) EG: my $var = 'FooBar'; my @arr = ('Hello', 'World'); So if you wanted to create a reference to $var or @arr, you can do it in following way: my $ref_to_scalar = \$var; or my $ref_to_array = \@arr; Now if you want to print the data structures through references, one of the way is: print "Value of scalar: ${$ref_to_scalar}\n"; print "Elements of array: @{$ref_to_array}\n"; I read about them in Beginning Perl, but I can't quite grasp them very > well. Thanks! I would strongly recommend to read it again. My advice - Do not advance to next chapter till you understand the current chapter. It's one of the best books on Perl and highly recommended for beginners. HTH Cheers, Parag
