Srsly. I'm not a n00b.
But This has thing has me scrambled.
An hour in and I'm flustered and no google searching or "Perl By Example" reading is helping.
I know it's something really freaking stoopid but c'mon. I think maybe I'm just tired.
Ok anyway here it is:
%entry = {$item_id=>\@data, $item_id=>\@data.....etc}

%entry is a hash populated by a foreach loop that runs through a set of about 200 items, breaking them apart for atomicity of the data (is that a real word I used just there?)
for my $key (sort keys %entry) {
#print Dumper($entry{$key}[1]);
my @entry;
        for (my $i = 0; $i <= $#entry; $i++){
          print $key, " ========================= \n";
          for (my $j =0; $j <= 10; $j++){
            print "Entry[$i][$j] = $entry[$i][$j] \n";
          }
        }
}

As long as I give an explicit value for $j's range, the output is fine. But I cannot figure out how to access the arraysize for $entry[$i]

And if there is a simpler way to do this that I could implement with my limited expertise in perl I'd love to hear some ideas.

Thanks!
