Hi Bob

Do you mean mean something like this?

SELECT bigtable
SEEK particularvalue
DO WHILE FOUND()
  REPLACE numericfield WITH newvalue IN bigtable
  SEEK particularvalue
ENDDO

or this...

SELECT bigtable
SET ORDER TO 0
REPLACE numericfield with newvalue FOR numericfield = particularvalue IN bigtaqble

Since you have an index on numericfield, Rushmore Optimization should kick in. It won't be as fast as the seek, but it should be close since there're fewer lines of code than the seek method.
