Explanation
The supervisor, or the Supervisor Call (SVC) for
the BLDL (build a directory entry list) macro, detected an error during
the processing of a LINK(X), XCTL(X), ATTACH(X), or LOAD macro with
the EP (entry point) or EPLOC (EP location (address)) operand.
The
reason code in register 15 identifies the error: Code
Explanation
04
The system could not find the module, whose entry point is the
value of the EP or EPLOC operand, in the indicated library (private
library, job library, or link library).  This situation can occur
when LSEARCH=YES is specified on the macro and the limited library
search fails to locate the module.  For an alias name, ensure that
the entry point attributes match that of the load module which was
previously loaded (that is, authorization, RMODE, entry point displacement). 
08
An uncorrectable I/O error occurred when the BLDL control program
routine attempted to search the directory of the library that contained
the program whose entry point was specified in the EP or EPLOC operand.
 This can occur if the specified library is an uninitialized partitioned
data set (PDS). An incorrect data extent block (DEB) has been detected
by the BLDL control program.  The DEB was built in other than protect
key 0 through 7.

0C
The supervisor attempted to search a library for the program that
the EP or EPLOC operand specifies and found that the library data
control block (DCB) is not open.
10
A program issued a LOAD macro with the explicit load option, but
there is no DCB parameter.  For explicit loads, the program must supply
the DCB parameter with the macro because the system searches for the
module that the LOAD specifies only in the library that the DCB parameter
specifies.
14
The system could not find the module, whose entry point is the
value of an EP or EPLOC operand of a XCTL(X) macro, in the link pack
area (LPA), which is where the module must be when the module is requested
by an SVC routine.
18
An SVC routine issued a XCTL(X) macro for a module.  The system
tried to search the link pack area directory to find the module, but
the directory had not as yet been built.
1C
The data control block (DCB), included as part of a LINK(X), LOAD,
XCTL(X), or ATTACH(X) macro is incorrect.
2C
Internal error.

System action
The system issues a message depending on the reason
code accompanying the abend: Code

 The system issues an ABEND dump.

System programmer response
For reason code X'08', resubmit
the job. Then have the operator enter a START GTF command specifying
tape output, MODE=EXT and TIME=YES. Have the operator reply TRACE=IO
in response to message AHL100A.
Format the output with the IPCS
GTFTRACE subcommand.
If the error recurs and the program is
not in error, see the system programmer response for messages in the
job log.
For reason code X'2C' or if the problem persists,
search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the ABEND dump and the source program listing for
the job.

Programmer response
If the reason code is X'04', this
is probably a user error. Make sure that the requesting program was
not incorrectly modified.  Make sure that the source library was indicated
correctly and that the indicated library does contain the requested
program.  For an alias name, make sure the alias attributes match
the attributes of the load module which was already loaded; check
the library authorization, RMODE, and alias entry point displacement).
Also, check that there are no duplicate aliases or related primary
module names in the library concatenation.  MVS™ expects that all module names, and aliases,
are unique across every library. Correct the error, and run the job
step again.
If the reason code is X'14' or X'18',
report this completion code to the system programmer.
If the
reason code is X'0C' or a X'1C', it is a probable
user error. Make sure that the DCB for the library is valid and open.
Correct the error and run the job step again.
