Assume that we're using Inproc session, then all the variables held in
session state are in-memory objects. So whether we can directly modify the
object without reassign it back to the sessionstate entry depend on its
class type. If it's of reference type, the session state entry just hold
the reference to that object, so we can certainly just update it without
explicitly reassign. If a value type, reassign is necessary....

| If "BOCSTransactio n" is an object, then this is true (just the
| reference is stored in Session, so you are updating the "real" object).
| However (just to be complete), if "BOCSTransactio n" is a struct
| (ValueType, sorry, don't know the VB name) then you will get a *copy*
| of the stored struct. So then you *will* have to "store back" the
| changed struct.
