>Thanks Peter. I don't think I was clear enough in my question however. I am using GETFLDSTATE() to check for field modifications within the record. When I determine that my field has changed I need to save the OLDVAL() version to an audit table as well as the current buffered value. This works fine for all fields except General fields. I get the error "Operation is invalid for a general field".

I see. So Foxpro help says, that Oldval() function returns a value. A general filed is a special
case and the value of its can not be returned by a function (I guess :-). That's why the general
fields are not supported by Oldval() and Curval() functions.
Supported types are Character, Currency, Date, DateTime, Double, Float,
Integer, Logical, Numeric, and Memo.

I think, you will have to use some other technique to save old values of general fileds.
