0Cx

Explanation
A program interruption occurred, but no routine
had been specified to handle this type of interruption.  Refer to
the instruction description in Principles of Operation to
find out how the instruction stops processing for the error condition.
The
last digit of this completion code is a hexadecimal number that indicates
the cause of the program interruption. Each X'0Cx' system
completion code has a reason code, which in most cases equals the
last digit. X'0C4' however, has several reason codes. Code
Explanation
0C1
Operation exception. The reason code
is 1.
0C2
Privileged-operation exception. The
reason code is 2.
0C3
Execute exception. The reason code is
3.
0C4
One of the following exceptions
occurred: 4
Protection exception. The key of the storage area that the running
program tries to access is different from that of the running program.
The key of the running program can be obtained from the PSW key field. The
key of the storage can be obtained using the IPCS LIST subcommand
if the DISPLAY(MACHINE) option is in effect. The DISPLAY(MACHINE)
option is not the IPCS-supplied default and must be enabled by explicitly
asking for the data or as a consequence of having used SETDEF to make
the DISPLAY(MACHINE) option the default. The programmer should
determine whether the program is running with the correct key or whether
the storage address is set up correctly. The protection exception
might have occurred when the program referenced a page that is protected
with the PGSER PROTECT service, or is defined as shared by the IARVSERV
service with a view of read-only.

10
Segment-translation exception. This error is caused by one of
the following: A program that was running disabled attempted to reference storage
while the page table for that storage was paged out. To correct the
error, page-fix the storage before a program running disabled attempts
to reference it.
A program attempted to reference storage that had not been obtained.
To correct the error, allocate the storage before attempting to reference
it.
A program running in a subspace attempted to reference storage
that was not accessible to the subspace at the time of error. To correct
the error, ensure that the program running in a subspace references
only the storage assigned to that subspace, or storage that can be
referenced by all subspaces.

11
Page-translation exception. This error is caused by one of the
following: A program that was running disabled attempted to reference storage
while that storage was paged out. To correct the error, page-fix the
storage before a program running disabled attempts to reference it.
A program attempted to reference storage that had not been obtained.
To correct the error, allocate the storage before attempting to reference
it.
A program running in a subspace attempted to reference storage
that was not accessible to the subspace at the time of error. To correct
the error, ensure that the program running in a subspace references
only the storage assigned to that subspace, or storage that can be
referenced by all subspaces.
SMS abend.  The reason code is X'12C'.

2B
ASTE-validity exception. This error is caused by one of the following:During access-register translation, except as in the case of the
following bullet, the access-list entry used designates an ASN-second-table
entry in which bit 0 is not zero. The access-list entry is the one
designated by the access register used.
During access-register translation of ALET 1 by BRANCH IN SUBSPACE
GROUP, the     subspace-ASTE origin (SSASTEO) in the dispatchable-unit
control table designates an     ASN-second-table entry in which bit
0 is not zero.
During a subspace-replacement operation, the subspace-ASTE origin
(SSASTEO) in the     dispatchable-unit control table designates an
ASN-second-table entry in which bit 0 is not zero. 

38
ASCE Type exception. This error is caused by one of the following: A program attempted to reference storage that had not been obtained.
To correct the error, allocate the storage before attempting to reference
it.
A program running in 64-bit addressing mode used a 31-bit pointer
that had the high order bit on. Note: Programs running in 31-bit mode
using 4-byte pointers often use the high order bit of a 4-byte pointer
to indicate 31-bit addressing mode, versus 24-bit mode. Also, certain
instructions will set the high order bit on in registers to indicate
addressing mode.

A program running in 64-bit addressing mode loaded a 31-bit pointer
into a 64-bit register and did not clear the high half of the register.
To correct the error, ensure that the program running in 64-bit addressing
mode clears the 33 high-order bits of any register when loading a
31-bit pointer into that register. 
A program that was running disabled attempted to access storage
that was not obtained as DREF.

39
Region-First exception. This error is caused by one of the following:A program attempted to reference storage that had not been obtained.
To correct the error, allocate the storage before attempting to reference
it.
A program running in 64-bit addressing mode used a 31-bit pointer
that had the high order bit on. Note: Programs running in 31-bit mode
using 4-byte pointers often use the high order bit of a 4-byte pointer
to indicate 31-bit addressing mode, versus 24-bit mode. Also, certain

3A
Region-Second exception. This error is caused by one of the following:A program attempted to reference storage that had not been obtained.
To correct the error, allocate the storage before attempting to reference
it.
A program running in 64-bit addressing mode used a 31-bit pointer
that had the high order bit on. Note: Programs running in 31-bit mode

3B
Region-Third exception. This error is caused by one of the following:A program attempted to reference storage that had not been obtained.
To correct the error, allocate the storage before attempting to reference
it.

System action
The system abnormally ends the task, unless a
recovery routine was provided to handle the interruption. The hardware
action is given in Principles of Operation.

System programmer response
Determine whether the problem program
or control program was in error.
If the problem program contained
an error, correct it, and run the job step again.
