Thanks. That looks really great.

I've been playing with it, and I did hit one snag so far. The arrays sotred in @{$matches{$element}{$sitekey}} contain possibly millions of elements, all stored in numerical order. If we assume that the ones being pushed into @arrayA are going to number a dozen or less, it seems really wasteful to me to sift through the entire array, for instance, once you've already reached values >= $upperlimit.

This is why I had included some of the early loop exits and so on. It will (presumaby) greatly increase the speed of the program, which is highly desirable. What are your thoughts on modifying your code here:

for my $hElem (@{$matches{$element}{$sitekey}}) {
    print "...in \$hElem\n";
    if ($hElem >= $lowerlimit && $hElem <= $upperlimit) {
        push (@arrayA, $hElem);
        }
    }

To something along these lines instead? :

for my $hElem (@{$matches{$element}{$sitekey}}) {
    next unless ($hElem >= $lowerlimit);
    break unless ($hElem <= $upperlimit);
    print "...in \$hElem\n"   
    push (@arrayA, $hElem);
    }
