appreciation of object methods, but I'll try to
put you straight as well as answer your questions

Take a look at it. It will do what you need.
Tom's original post was about how to call the 'clone'
method of a given object. His assumption was that
clone was a built-in, so he was failing to find
documentation on it. It was not a question
to by a ref as an object. But what
does that mean in actual terms, the access method for
package variables doesn't change.
Thanks again,
Tom Norwood.

sub clone {
