32-bit E32 parameter list
In 32-bit general register 1, DFSORT places the address of a parameter list that contains the file increment, the record address and the user address constant. The list is three fullwords long and begins on a fullword boundary. The format of the parameter list is:
32-bit E32 User Exit Parameter ListLocation
|
Contents |
---|---|
Bytes 1 through 4 | Increment of next file to be used for input |
Bytes 5 through 8 | Address of next input record |
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 next input record from the requested input file in the second word of the parameter list
- Put the return code in 32-bit register 15.
