This, IMO, really pushes me toward Walden's solution of using SQL. That's a really nice use of the update statement. Tim, if you don't have the SQL licensed product installed, you can still do this by creating a query management (*QMQRY) and then execute STRQMQRY from a CL or whatever. Here's how to do it so that you don't even have to hard-code the file and field names:
