>repeating Craig's answer, how would vfp know what your custom methods are expecting? this should be stored in your documentation and in comments in the class so you can look up what you don't remember..

It should do when I'm subclassing my own class and redefining its custom method - it'd just have to repeat the LParameters line from the parent class (I believe it already keeps an eye on the parent class while I'm designing a subclass, else how would it know the proper defaults in the PEM window). That's what it does if you are subclassing its native classes and redefining a standard method.
