When this variable is a null value, then no allocation is done for compiler
system library data sets. In this case, the use of //DD:SYSLIB on the -I
option and the #include directive will be unsuccessful. Unless there is a
dependency on the use of //DD:SYSLIB, it is recommended that for
improved performance this variable be allowed to default to a null value.
prefix_CVERSION
The version of the z/OS XL C/C++ compiler to be invoked by c89/cc/c++.
The setting of this variable allows c89/cc/c++ to control which z/OS XL
C/C++ compiler program is invoked. It also sets default values for other
environment variables.
The format of this variable is the same as the result of the Language
Environment C/C++ run-time library function _librel(). See z/OS XL
C/C++ Run-Time Library Reference for a description of the _librel()
function. The default value is the result of the C/C++ Run-Time library
_librel() function.
prefix_CXXSUFFIX (15)
The suffix by which c++ recognizes a C++ source file. The default value is
C. This environment variable is only supported by the c++ and cxx
command names. _CXX is the only valid prefix.
prefix_CXXSUFFIX_HOST (15)
The suffix by which c++ recognizes a C++ source data set. The default
value is CXX. This environment variable is only supported by the c++ and
cxx command names. _CXX is the only valid prefix.
prefix_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 out of the range shown here (that is, less than 0 or greater than 8), then
c89/cc/c++ dynamic allocation message processing is disabled. The default
value is 4. Following are the values:
0 Informational
1–4 Warning
5–8 Severe
prefix_DAMPNAME (14)
The name of the dynamic allocation message processing program called by
c89/cc/c++. It must be a member of a data set in the search order used for
MVS programs. The default dynamic allocation message processing
program is described in z/OS MVS Programming: Authorized Assembler
Services Guide. The default value is IEFDB476.
prefix_DCBF2008 (21)
The DCB parameters used by c89/cc/c++ for data sets with the attributes
of record format fixed unblocked and minimum block size of 2008. The
block size must be in multiples of 8, and the maximum depends on the
phase in which it is used but can be at least 5100. The default value is
(RECFM=F,LRECL=4088,BLKSIZE=4088).
prefix_DCBU (21)
The DCB parameters used by c89/cc/c++ for data sets with the attributes
