I have a custom class 'pippo'
Now I try to play with objects:

opippo = createobject('pippo') && create opippo object
opippo.tag = 'something'
refpippo = opippo && crate a reference to opippo object changes made to refpippo are reflected to opippo.

How to obtain a diffrent copy (not a reference) of opippo with prop tag just set and to be able to change it without reflect to opippo and refpippo ?

Thanks,
Dino.
