note lima1 You almost had it. Just pass a reference to the hash to your function with \%hash. You can access the elements without dereferencing with the -> operator. <code> #!/usr/bin/perl use strict; sub display { my $ref01 = shift; foreach my $key (sort keys %{$ref01}) { print "$key: $ref01->{$key}[0] $ref01->{$key}[1] $ref01->{$key}[2]\n"; } } my %hash1; $hash1{'fruit'} = ['apple', 'orange', 'plum']; $hash1{'vegetable'} = ['leek', 'carrot', 'peas']; display (\%hash1); foreach my $j (sort keys %hash1) { print "$j: $hash1{$j}[0] $hash1{$j}[1] $hash1{$j}[2]\n"; } </code> 860644 860644
