Explanation
An error occurred in processing for a write to
operator (WTO) or write to operator with reply (WTOR).
Register
15 contains a hexadecimal error code in the format xxxxyyyy.
The fields in this error code are the following: xxxx
This halfword is for IBM® internal
use only.
yyyy
This halfword is the unique reason code identifier. Only yyyy is
listed below.

The following are the yyyy values
and their meanings: Code
Explanation
0002
The caller issued a WTO or WTOR specifying an incorrect number
of lines. Possible errors:A WTOR was specified with SYNCH=NO and more than one line was
specified
A multiple-line WTO with zero lines was specified
A WTO or WTOR was specified with SYNCH=YES, and more than 14 lines
were specified

0003
The parameter list that the caller passed does not reside in storage
that the caller can access.
0004
The caller requested a WTO or WTOR with a text length of zero,
or a multiple-line WTO was specified with one of the lines having
a text length of zero.
0005
A caller requested a WTO or WTOR with a text length too long for
the type of line. The text was truncated to the maximum length for
that type of line. 
0006
 A caller that was not in key 0-7 requested one or
more of the authorized WTO keywords.
0007
The caller requested mutually exclusive functions. Examples: Both CONSID and CONSNAME were specified
A multiple-line message requested incompatible or invalid line
types for a line
A WTOR prefix was specified with a WPX

0008
The caller supplied an incorrect parameter list structure. Here
are possible reasons:WPX length was not correct.
WQEBLK parameter was specified with an incorrect WPL.
Zero address was specified for the WPL.

0009
The caller requested a WTO or WTOR with a zero text address, or
a multiple-line WTO was specified with one of its lines having a zero
text address.
000B
The caller specified LINKAGE=BRANCH with unsupported keywords.
000C
The caller issued a WTOR with SYNCH=NO and LINKAGE=BRANCH.
000E
This processor does not hold the restart resource.
000F
The system could not access the action code storage.
0010
The system found an incorrect value in the write-to-operator queue
element (WQE).
0011
The console name is reserved or incorrect.
yy12
The system was unable to create or expand an SQA cellpool. The
return code from the failing STORCSR will be found in yy.
yy20
A GETCELL for an operator reply element (ORE) failed. The return
code from the GETCELL macro will be found in yy.
yy21
The system could not build a cellpool for an operator reply element
(ORE). The return code from the BLDCPOOL macro will be found in yy.
yy22
The system could not obtain storage for an operator reply element
(ORE). The return code from the STORAGE macro will be found in yy.
0030
A write-to-operator queue element (WQE) for an operator reply
could not be obtained.
yy40
A recovery environment could not be established. The return code
from the ESTAE macro will be found in yy.
yy50
A LOADWAIT request failed. The return code from the BLWLDWT service
will be found in yy.
yy51
The system could not obtain needed storage. The return code from
the STORAGE macro will be found in yy. When yy
equals 00, a WTO multi-line exceeded the maximum 65533 total lines
allowed. The WTO multi-line connect was too large.
yy52
A failure occurred in the data block create routine. The return
code from the data block routine will be found in yy.
0053
Storage could not be obtained for the dummy SSI control blocks
(SSOB, SSWT, WQE, ORE). Processing continues for this message; however,
the SSI is not called for this message.
0055
The caller requested a function that requires additional parameters.
0060
Delayed issued WTO subtask timed out.
yy61
Delayed issued WTO subtask could not establish recovery, where yy is
the ESTAEX return code.
yy62
Delayed Issued WTO task could not attach a subtask where yy is
the ATTACH return code.
0063
The first line of a multi-line message cannot be marked verbose.
Fyyy
An internal processing error occurred. The yyy field
contains the abend code of the failure.

System programmer response
Search problem reporting data bases
for a fix for the problem. If no fix exists, contact the IBM Support Center.
If the reason code
is X'0012', then increase the SQA/ESQA values in IEASYSxx
in parmlib.

Programmer response
Correct the program issuing the WTO or WTOR
macro. Recompile the program.  Run the job step again. If the problem
persists, notify the system programmer.
