I would have a Move method at the superclass level, that way all calls to "vehicle" subclasses would message the same way. The actual functionality (code) of the Move specific to each vehicle subclass would be at the subclass level (car, airplace, rowboat)

oChevy=CREATEOBJECT("Car")
oChevy.Move()

Why is there bloat? The functionality is at the subclass. The subclass is object specific. If the code was in the superclass, I would agree.

ROFL....I hear that.
