DFSORT calls to your EFS program z/OS DFSORT Application Programming Guide SC23-6878-00 |
|
DFSORT makes five functional calls (Major Calls 1 through 5) at various phases to transfer information across the EFS interface, between DFSORT and your EFS program. DFSORT can make multiple calls at Major Calls 2 and 3. Refer to Figure 1 and Figure 2 as you read this section for illustrations of the relationships between program phases and calls during run-time. Figure 1. EFS
Program Calls for a Sort. The figure also shows the calls
to the EFS program EFS01 and EFS02 exit routines.
Figure 2. EFS
Program Calls for a Merge or Copy. The figure also shows
the calls to the EFS program EFS01 and EFS02 exit routines.
