(Minor nit: it's not a command. It's accessing an array reference. Read up on Perl data structures.)

$slist->{data} is an array reference of other array references (the "rows" in the list) each item of which is a piece of data (the "columns" in each row). Fiddle about with this: 

for my $row (@{$slist->{data}}) {
    print "Row:\n";

    for my $col (@{$row}) {
        print "    $col\n";
    }
}

or use Data::Dumper to visualize the data structure in a more Perlish way: 
use Data::Dumper;
print Dumper($slist->{data}), "\n";

(Untested code.)
