Record processing order

The order of record processing when using EFS is similar to processing without it. Figure 1 illustrates the record processing sequence for a sort or merge and Figure 2 illustrates the record processing sequence for a copy when EFS processing is in effect.

The figures illustrate the same points as described in Figure 1 with the following exceptions:

When record processing is done for an INCLUDE or OMIT control statement, an EFS02 user exit routine is called to perform the comparison logic for the relational conditions with EFS fields.
When record processing is done for a SORT or MERGE control statement, an EFS01 user exit routine is called to perform the extraction process for EFS control fields.
