Explanation
The error occurred during the processing of SYNADAF,
where it was determined that the IOB address was incorrect.

System action
Register 15 contains the IOB address in error: For BDAM, BPAM, and BSAM, SYNADAF obtained the IOB address from
the DECIOBPT field of the DECB; for these access methods, the DECB
address was passed to SYNADAF as the PARM2 operand on the macro instruction,
and was contained in register 0 on entry to the user's SYNAD routine.
 Verify that the PARM2 operand on the SYNADAF macro instruction was
correctly specified and that the DECIOBPT field has not been overlaid.
For QSAM, BISAM, and QISAM, SYNADAF received a pointer to the
IOB as the PARM2 operand on the macro instruction. The address passed
to SYNADAF should have been the address contained in register 0 on
entry to the user's SYNAD routine.  Verify that the PARM2 operand
on the SYNADAF macro instruction was correctly coded.
For the EXCP access method, verify that the PARM1 operand of the
SYNADAF macro instruction specified the correct IOB address.

System programmer response

is not in error, look at the messages in the job log for more information.
Search problem reporting databases for a fix for the problem. If no
fix exists, contact the IBM® Support
Center. Provide the JCL and the program listing for the job.

Programmer response
Correct the error and rerun the job step.
