Can you keep parent classes in a separate APP from the working child classes?

When you compile a child class into an APP, FOXPRO will automatically INCLUDE all the parent classes.

I want to EXCLUDE the parent classes and keep them in a separate APP.

"SET CLASSLIB to PARENTCLASS in PARENT.APP" doesn't seem to work because I get that wonderful error message "CANNOT INSTANTIATE CLASS ...CANNOT FIND PARENTCLASS.VCX"

Any ideas?
