Functional Description:: Use the STRAIN stage to filter all bytes of each record thru a selected sieve operation. The sieve will alter all characters that do not meet the requirements of the sieve definition. Characters matched by the sieve will be changed to space.

If the collapse option is specified then characters that are filtered out will have their positions collapsed left so that no gap is left.
