OBJECT POS X suggests that OBJECT really isn't an object at all; it's an
area of memory over which the structure POS is being applied to get the
variable at offset X. I'm not quite sure whay you would want OBJECT X in
such a case. For most uses, defining and knowing the offset of X is
rather pointless since the class (and any objects derived from it)
encapsulates the variable. Althought there are similarities, structures
and classes are not necessarily the same, and classes may not always be
supersets of structures.
