If iKey1 is, say, a 5 digit field, you could have an index expression 100,000*iKey1 + iKey2. A tag like this could come in handy for ordering things if you are using the table itself, and not a view. But as many people here have told me, avoid compound primary keys and meaningful primary keys. At the very least, if you use compound keys, you will have to write your own RI code, because the RI code generated by vfp won't handle them. It is better to generate a surrogate key.

What does everyone think about him using this tag for a candidate index?
