IEC999I

Explanation
text is one of the following: mod ,sub ,DEB
ADDR = debaddr [-1] [DSN = dsname]
mod ,sub ,WORK
AREA = workarea
mod ,jjj ,sss [,dev ,volser ,dsname ,nnn LOST
BLOCKS]
mod ,jjj ,sss [,errtext]

This message is issued due to a failure during OPEN/CLOSE/EOV,
DADSM, or task close processing.
In the message text:  mod
The name of the module in which the error occurred.
 sub
The subroutine of the CSECT within the module in error.
 debaddr
The address of a DEB that could not be properly closed. The DEB
has been removed from the TCB DEB chain
-1
If -1 follows the DEB address, it means that the DCB is not accessible
and implies that a program freed the storage while the DCB was open.
 xxxxxx
A text string.
 workarea
The address of the work area for the module in error, which should
appear in an SDUMP.
jjj
The job name.
sss
The step name.
dev
The device number.
volser
The volume serial number.
dsname
The data set name.
nnn
The number of blocks written to the hardware buffer but not written
to the tape medium.
errtext
Text which describes the error which will result in O/C/EOV issuing
the following ABEND0C1.

The error message includes the unit address,
volume serial number, and data set name only if the error occurred
during DADSM processing.

System action
The task is ended. If errtext is
specified an ABEND0C1 will be issued.

Operator response
None

System programmer response
None

Programmer response
Check previous messages or abends to help
determine the reason for the failure.
If debaddr=
is specified, the failure occurred during task close. The problem
is probably with the program that opened the data set. The most common
problem is the program modifying or freeing the storage that contains
an open DCB. A '-1' after the DEB address means the open DCB or
ACB storage is not accessible. Correct the problem and run the
job again.
If workarea= is specified, a system
problem was encountered. Prior to contacting hardware support personnel
for help, make the SDUMP and failing job available. For ISO/ANSI tape
labels, the system might have detected an incorrect IECIEPRM parameter
list passed by an MVS™ routine.
If
job name (jjj) and step name (sss)
are specified, an indeterminate error (a program check or a machine
check) was encountered during OPEN/CLOSE/EOV or DADSM processing. 
If
this message is accompanied by a CO3 abend and a slip dump is obtained,
searching the system trace table for the DEB address and corresponding
DCB address might help determine the cause of the problem. For this
to be effective, the system trace table might need to be enlarged
and branch tracing turned off. A trace table size of 256K should be
sufficient.
If errtext is specified, a system
problem was encountered during O/C/EOV processing. Before calling
the IBM® Support Center make
the 0C1 dump and failing job available.
