Special Processing

Use the special processing flag of the AttributeSetFilter command to indicate how records with a value of zero are handled.

To handle uninitialized data, the value of zero can be treated as a special case by setting a zero process flag within the command. Setting the flag to drop indicates values of zero are to be discarded. Setting the flag to keep indicates values of zero are to be passed through regardless of whether or not they match the filter criteria. Not setting the flag indicates that values of zero are not to be given any special consideration.
