Larry,

>No, I don't open the database and hand code the rules. I use the RI Builder from Effective Techniques.

O.K. That explains. But your answer to the original question:

>I do agree that RI should be coded manually (as that is the only way it can be done if VFP currently). However, I would not do it in PRG code, I would use stored procedures and triggers; hence, use a database.

seems a bit misleading. Can we conclude that it is preferred to use some sort of RI builder that generates constraints in the database itself rather than program the RI in the application (which was in fact the question) ???
