Can someone tell me what's wrong here? 

sub processfile {
    my $script = "/export/home/limo/Perl/exfields.pl -e";
    my ($file, $list) = @_;
    my %hash;
    my @list = (split /,/, $list);
    
    foreach my $arg(@list) {
     open(FILE, "$script $arg $file |") or die "System error: $!\n";
     while (<FILE>) { 
            chomp;     
            #  print "$_\n"; returns expected results      
            
            my @array = split;
            
#  printing each array element also passes here
           
       $hash{$arg} = [@array];
       push (@{ $hash{$arg} }, @array) unless /^\#|none|unkno/i; 
        
     }

    }
    
    foreach my $keys( sort keys %hash) {
        print "@{ $hash{$keys} }\n";

#  print statement here returns 1 "value "value" pair per key

    }
    close FILE;
    return %hash;   
}

Printing passes up until either the point where I populate the hash or try to print each key/value. What am I doing wrong here? FWIW, I am using Cookbook, recipe 11.2, pg. 372, for example.
