Thank you! You guys are really amazing. I think your approach is basically the same as what sundialsvc4 was suggesting. I'm still struggling to grasp how Perl objects work. JavaFan wrote "A Perl object is a reference that's blessed into a package", and if I understand your code right, the reference in this case is to the hash that contains the parameters ("bless \%params, $class"). I agree that what I'm trying to do is trivial, but I am none the wiser about why none of the other versions suggested worked, except that the evaluation of the passed variable name was problematic.
