ld
be a C370LIB object library or a load library. See the description of the –l
libname operand for more information about using data sets as libraries.
file.o Specifies the name of an object file, produced by z/OS compiler or
assembler, to be link-edited.
To specify an MVS data set name to be link-edited, precede the file name
with double slash (//), in which case the last qualifier of the data set name
must be OBJ.
If a partitioned data set is specified, more than one member name may be
specified by separating each with a comma (,):
Example:
ld //file.OBJ(mem1,mem2,mem3)
file.x Specifies the name of a definition side-deck produced by ld when creating
a DLL (dynamic link library), and used by ld when linking an application
using the DLL. See the description of side-deck processing in z/OS MVS
Program Management: User’s Guide and Reference.
To specify an MVS data set name, precede the file name with double slash
(//), in which case the last qualifier of the data set name must be EXP.
If a partitioned data set is specified, more than one member name may be
specified by separating each with a comma (,):
Example:
ld //file.EXP(mem1,mem2,mem3)
Environment variables
You can use environment variables to specify necessary system and operational
information to ld. When a particular environment variable is not set, ld uses the
default shown. For information about the JCL parameters used in these
environment variables, see z/OS MVS JCL User’s Guide.
_LD_ACCEPTABLE_RC
The maximum allowed return code (result) of the binder invocation. If the
result is between zero and this value (inclusive), then it is treated internally
by ld exactly as if it were a zero result, except that message IEW5033 may
be issued. For more information about binder return codes, see z/OS MVS
Program Management: User’s Guide and Reference. The default value is:
"4"
_LD_ASUFFIX
The suffix by which ld recognizes an archive file. This environment variable
does not affect the treatment of archive libraries specified as -l operands,
which are always prefixed with lib and suffixed with .a. The default value is:
"a"
_LD_ASUFFIX_HOST
The suffix by which ld recognizes a library data set. This environment
variable does not affect the treatment of data set libraries specified as -l
operands, which are always used exactly as specified. The default value is:
"LIB"
_LD_DAMPLEVEL
The minimum severity level of dynamic allocation messages returned by
dynamic allocation message processing. Messages with severity greater
than or equal to this number are written to stderr. However, if the number is
