I don't follow your second paragraph. C is defined as A INTERSECTION B. Since A and B do not have any information objects in common, the result of the intersection is the empty but extensible set. As such, it is not possible to determine what objects there are in C except at runtime. > Set C contains exactly the same as set A (i.e. at least a1, a2, a3) as > there is no common elements in set A and set B. Closely think through what you are saying here. If there are no common elements in sets A and B, and set C is the intersection of A and B, how does C end up containing the elements of set A? ------------------------------------------------------------------------- Bancroft Scott Toll Free :1-888-OSS-ASN1 OSS Nokalva International:1-732-302-0750 [EMAIL PROTECTED] Tech Support :1-732-302-9669 x-1 1-732-302-9669 x-200 Fax :1-732-302-0023 http://www.oss.com > Best Regards, Gy�rgy > > ============================================ > dr.
