Hi Monks,

I am trying to have a look at the elements of arrays in a dynamically created HoHoA. When I try something like this:

 my ($span, %matches) = @_;
 my ($site, $fastaseq, $fasta, $sitekey) = '';
 my ($setscounter,$lowerlimit,$upperlimit,$i,$set,$yes,$low,$hit) = 0;
 my %sets = ();

 FASTA: for $fastaseq (keys %matches) {
       $sitekey = '';
       SITEKEY: for $sitekey (sort {$a <=> $b } keys %{$matches{$fasta
+seq}}) {
         if (@{$matches{$fastaseq}{$sitekey}}) {
          SET: foreach $hit (@{$matches{$fastaseq}{$sitekey}}) {
            print "\$matches{$fastaseq}{$sitekey} is: $matches{$fastas
+eq}{$sitekey}\n";
            print "\$hit is: ",$hit,"\n";
            print "\$hit is: ",$matches{$fastaseq}{$sitekey}[$hit],"\n
+";
            if ($hit >= $lowerlimit && $hit <= $upperlimit) { #some co
+de
}}}}}

I get the following output:
$matches{>LG_XIV}{0} is: ARRAY(0x182bb14)
Use of uninitialized value in print at MyScript line 386.
$hit is: 
$hit is: 6906413
Use of uninitialized value in numeric ge (>=) at MyScript line 388.

BTW - line 386 is the first print $hit line, and so on. I'm using use strict and use warnings, and I am scratching my head like mad to try to figure out what's wrong. I've been staring at this so long, I am losing my train of thought anymore.

If I replace the straight $hit calls in the greater than comparison with $matches{$fastaseq}{$sitekey}[$hit], I get no change.

Basically, I just want to know what each of the values in the array <code>$matches{$fastaseq}{$sitekey} array is, and then throw it into the comparison on that if (>= && <=) line. But, no dice.

Does anyone have any ideas, or can point out what I'm doing wrong?

Thanks,
Matt
