The most basic method for creating a reference is to use the backslash (\) operator. For example, to create a simple scalar reference, you would use something like the following:
#!/usr/bin/perl -wT use strict; my $name = "Selena Sol"; my $reference = \$name;
Notice the backslash character before $name.
Creating array, hash and subroutine references follows the exact same process such as:
my $array_reference = \@array_name; my $hash_reference = \%hash_name; my $subroutine_ref = \&sub_name;
