z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

c89, cc, and c++
normally used by c89/cc/c++ when the output file is a data set which is not
a PDSE ( partitioned data set extended).
Note: The prelinker and XPLINK are incompatible. When using the link
editor XPLINK option, the prelinker cannot be used. Thus, specifying
the prelinker on this variable will have no effect.
The format of this variable is a set of binary switches which either enable
(when turned on) or disable (when turned off) the corresponding step.
Turning a switch on will not cause a step to be enabled if it was not already
determined by c89/cc/c++ that any other conditions necessary for its use
are satisfied. For example, the IPA Link step will not be executed unless the
-W option is specified to enable the IPA linker. Enabling the IPA linker is
described under the -W option on page 78.
Considering this variable to be a set of 32 switches, numbered left-to-right
from 0 to 31, the steps corresponding to each of the switches are as
follows:
0-27 Reserved
28 TEMPINC/IPATEMP
29 IPALINK
30 PRELINK
31 LINKEDIT
Example: To override the default behavior of c89/cc/c++ and cause the
prelinker step to be run (this is also the default when the output file is a
data set which is not a PDSE), set this variable to: 0xffffffff or the
equivalent, -1. The default value when the output file is a z/OS UNIX file or
a PDSE data set is 0xfffffffd or the equivalent, -3.
Note: The IPATEMP step is the IPA equivalent of the TEMPINC (automatic
template generation) step, just as the IPACOMP step is the IPA
equivalent of the COMPILE step. See the description of IPA under
the -W option for more information.
prefix_SUSRLIB (16)
The user library data set concatenation to be used to find COPY and
MACRO files during assembly (before searching prefix_SSYSLIB). The
default value is "" (null).
prefix_TMPS
The use of temporary files by c89/cc/c++ can be controlled with this
variable.
The format of this variable is a set of binary switches which either cause a
temporary file to be used (when turned on) or a permanent file to be used
(when turned off) in the corresponding step.
The correspondence of these switches to steps is the same as for the
variable prefix_STEPS. Only the prelinker and IPA linker output can be
captured using this variable.
Example: To capture the prelinker output, set this variable to: 0xfffffffD or
the equivalent, -3. The default value is 0xffffffff or the equivalent, -1.
prefix_WORK_DATACLAS (18)
The DATACLAS parameter used by c89/cc/c++ for unnamed temporary
(work) data sets. The default value is "" (null).
