A Person 'object' is implemented in three SRVPGMS.

Curious. Why? Surely a given object should be implemented in a single service program--at least from the point of the consumer? The PERSON service program may use other service programs (e.g., ADDRESS, ENTITY, etc.) but that shouldn't affect the consumer.

Seems to me your binding issue could be solved by having a single PUBLIC binding directory which contains all your "object" service programs. This is referenced by your consumers so they can resolve to all 'objects' and 'methods'.

For development you would either:

o not use binding directories but rather list the modules and service programs in the creation script (I'm presuming you use some form of Change Management System to perform your builds)

o or use binding directories only for modules (one per service program). You would still list the service programs directly.

You'd still have to edit the build scripts if you split a service program but it's easier to search scripts (i.e., source) than binding directories. If you frequently have to split service programs (i.e., objects) then you don't have your design correct.

I'm not suggesting that nested binding directories wouldn't be a good thing (although cyclic references could prove problematic) but rather that I think it's not required.
