I implemented the mirroring by creating a record-level validation rule that calls a stored procedure that basically does:

DO CASE
CASE OLDVAL(desc) != desc && if desc has changed, propogate the change
REPLACE cDesc WITH desc
CASE OLDVAL(cDesc) != cDesc && if cdesc has changed, propogate the change
REPLACE cDesc WITH desc
CASE desc != cDesc && if they're different, assume that desc is correct
REPLACE cDesc WITH desc
ENDIF

This works fine in all the testing I've done. But, I've got a VFP 3.0 book that says "validation code cannot change any field in the current record". Maybe the book is wrong. I couldn't find any VFP 5.0 doc saying it was OK or not OK to do this.
