215

Explanation
The error occurred during the processing of SVC
21 (STOW).  This system completion code is accompanied by message
IEC910I. Refer to the explanation of message IEC910I for complete
information about the task that was ended and for an explanation of
the return code in register 15.

System action
The STOW task recovery routine has been invoked.
If the caller's DCB is in the caller's region, an attempt was made
to trace it to the SYS1.TRACE data set.

Operator response
Start a generalized trace facility (GTF) trace,
and re-create the problem.  Reply to message AHL100A with:      TRACE=SYS,USR,SLIP

On
the DD statement for the data set in error, specify:      DCB=DIAGNS=TRACE

System programmer response
  If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases 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
For return codes 01, 02, and 03, verify
that register 1 contained the correct DCB address prior to issuing
SVC 21 and that the DCB has not been overlaid since being opened.
 For return code 04, verify that register 0 contained the correct
parameter list address and that the list is within the caller's region
prior to issuing SVC 21.
