32-bit E35 parameter list
In 32-bit general register 1, DFSORT places the address of a parameter list that contains the two record addresses and the user address constant. The list is three fullwords long and begins on a fullword boundary. The format of the parameter list is:

|
Contents |
---|---|
Bytes 1 through 4 | Address of record leaving DFSORT |
Bytes 5 through 8 | Address of record in output area |
Bytes 9 through 12 | User exit address constant |
DFSORT provides a 72-byte Format 0 save area pointed to by 32-bit register 13 in which the exit can save the 32-bit registers.
Before returning control to DFSORT, you must:
- Place the address of the record in 32-bit register 1.
- Put the return code in 32-bit register 15.
