If you want to know how many refs are in the array, you can grab it with $#array to get the size of the array. That'll just tell you how many references are stored in the array (a reference is a scalar, though it may point to non-scalar data). You should probably take a look at the perldoc on references -- perldoc perlref, if I remember correctly. Also, buy a copy of Programming Perl -- there's no excuse not to, it's an absolutely excellent book -- and read chapter 4.
