>I have been given a conversion file of customer numbers. Follows the typical old_cust, new_cust format. Every customer number on every DBF will have to be renumbered. There are 12 tables. Some sites will have tables that are 32mg with 250,000 records. Each record contains a customer number.

How about something like

SELECT 0
USE ConversionTable
INDEX ON OldCustomerNumber TAG OldCustomerNumber
SELECT 0
USE maindatatable
SET RELATION TO CustomerNumber INTO ConversionTable
REPLACE ALL CustomerNumber WITH ConversionTable.NewNumber FOR FOUND("ConversionTable")
