HI everyone,
I have two problems to pass an array of hashes and I can't find out how to solve them. 
#!/usr/bin/perl
use strict;

sub display(\%)
 {
 my $i;
 my @ref01 = shift;

 foreach $i (sort keys (%{$ref01[0]})) {
  print "$i: ${$ref01[0]}{$i} ${$ref01[1]}{$i} ${$ref01[2]}{$i}\n";
  }
 }

my (%hash1, $j, $z);

$hash1{'fruit'} = ['apple', 'orange', 'plum'];
$hash1{'vegetable'} = ['leek', 'carrot', 'peas'];

$z = display (%hash1);

foreach $j (sort keys (%hash1))
 {
 print "$j: $hash1{$j}[0] $hash1{$j}[1] $hash1{$j}[2]\n"; *
 }

The output: 
fruit: ARRAY(0x8775818)
vegetable: ARRAY(0x878fea8)
fruit: apple orange plum
vegetable: leek carrot peas

Obviously, the array is incomplete and I can't dereference it. It would be great if someone could be able to modify that script.
Thank you for your help and your patience.
