The OraFields collection maintains a list of OraField objects. The list is not
modifiable; you cannot add to or remove from this collection.
You can access the OraField objects in this collection by subscripting (using
ordinal integers) or by using the name the object was given at its creation.
You can obtain the number of OraField objects in the collection by using the
Count property. Referencing a subscript that does not lie within the collection (0
to Count-1) results in the return of a NULL OraField object.
