Explanation
A reason code in register 15 identifies the error: Code
Explanation
04
An error was detected during the processing of a LOAD macro. 
The LLE (load list element) count (responsibility count), indicating
the number of load requests for a module, is greater than the allowable
maximum, which is 32767.
08
An error was detected during processing of a LINK(X), XCTL(X),
ATTACH(X), or LOAD macro. The CDE (contents directory element) use
count, indicating the number of LINK(X), XCTL(X), ATTACH(X), or LOAD
requests for a module, is greater than the allowable maximum, which
is 32767.
0C
The failing program has issued an XCTL(X) request, but the program
has an outstanding program linkage that has not completed properly.
This commonly occurs when a program issues a program call (PC) and
then issues an XCTL(X) request before issuing a program return (PR).
100
An error was detected during processing of a CSVINFO request.
It was determined that an Extent List (XTLST) control block contained
incorrect information.

System action
For reason codes X'04' X'08',
the task ends unless ERRET is specified on the macro. For reason codes X'0C' and X'100',
the request is terminated. The system issues a message depending on
the reason code accompanying the abend: Code
Message/ABEND Type
04
 CSV001I/ABDUMP
08
 CSV002I/ABDUMP
0C
 CSV030I/ABDUMP
100
        /SVCDUMP

System programmer response
For reason code X'100', search
problem reporting databases for a fix for the problem. If no fix exists,
contact the IBM® Support Center.
Provide the dump and logrec entries associated with with abend. For
the other reason codes, if the error recurs and the program is not
in error, see the system programmer response for the messages in the
job log.

Programmer response
Check for program errors, such as endless
loops, that cause macros to be run too often. Ensure that the program
logic does not permit improper program linkage. After making corrections,
recompile and run the job step again.
