property-id myProp1 string private.
    setter protected.  *> this is incorrect
    set property-value to "1234"
    getter.		
end property.
end class.

class-id myClass2.
property-id myProp2 string public.
    setter protected.			*> this is correct
    set property-value to "5678"
    getter.
    declare myString as string.
    set myString to property-value
end property.
end class.
