EFS02 parameter list

DFSORT sends three words to the EFS02 exit routine each time it is entered:

The address of the correlator identifier
The address of the input record
The address of the EFS program context area.

DFSORT places the address of a parameter list in register 1. The list begins on a fullword boundary and is three fullwords long. The format of the parameter list is:

The format of the parameter list is:Byte 1	Byte 2	Byte 3	Byte 4
00	00	00	Correlator identifier
Address of the input record
Address of the EFS program context area

The EFS02 exit routine must return one of the following return codes in general register 15:

0: True
: The record passed the INCLUDE or OMIT test for the relational condition of an EFS field. If applicable, processing continues with the next relational condition. Otherwise, DFSORT accepts the record if INCLUDE is specified or omits the record if OMIT is specified.
4: False
: The record did not pass the INCLUDE or OMIT test for the relational condition of an EFS field. If applicable, processing continues with the next relational condition. Otherwise, DFSORT omits the record if INCLUDE is specified or includes the record if OMIT is specified.
16: Terminate
: An error occurred in processing the INCLUDE or OMIT logic; terminate DFSORT.
