Jim,

>Yes y9ou can do that. However, you cannot ever open that table if tyhe UDF is not visible to VFP as it will cuase an error that will prevent the table from opening. Also, you must insure that the UDF always returns a value of the same type and length or else the index will become corrupt.

I think you're right saying that this shouldn't be done. However, in the past I used index based on UDFs to provide some trigger functionality within FPW 2.x and I can imagine that there will be (very) exceptional cases where and UDF based index can be of any benefit. I would probably store the UDF as a Stored Procedure.

But of course you're right it souldn't be used in general.
