User exit 9 is called (when present) for each record selected before writing the record to the output data set. The user exit is supplied with the record address, and returns an action code as follows:

1	Write record to DDOUT1;
2	Write record to DDOUT2;
3	Write record to DDOUT1 and DDOUT2;
I	Ignore this record.

The above data sets must have the same block size. See the Adabas DBA Reference documentation for more information about user exits.
