Tailoring cataloged procedures, REXX EXECs, and EXECs

A system programmer must modify the cataloged procedures, and REXX EXECs before they are used.

The following data sets contain the cataloged procedures and REXX EXECs that are to be modified:

CBC.SCCNPRC
CBC.SCCNUTL
CEE.SCEEPROC
CEE.SCEECLST

Most customization for REXX EXECs is in CBC.SCCNUTL(CCNCCUST) and CEE.SCEECLST(CEL4CUST).

The system programmer can make the following changes to REXX EXEC CCNCCUST by editing member CCNCCUST, which resides in data set CBC.SCCNUTL:

Change or add more binder options by modifying BINDOPTS parameter.
Change the prefix for Language Environment® LIBPRFX from the IBM-supplied default to the high-level qualifier that you chose.
Change the prefix for XL C/C++ Base Compiler LNGPRFX from the IBM-supplied default to the high-level qualifier that you chose.
Change the prefix for Run–Time Library Extensions CLBPRFX from the IBM-supplied default to the high-level qualifier that you chose.
To use Japanese prelinker messages, change PLANG from EDCPMSGE to EDCPMSGK.
Change the unit parameter TUNIT if the default SYSDA does not suit your system.
If you need to use the old syntax of CC, change CCSYNTAX to OLD or BOTH.
We also have kept the support for the old syntax for compatibility with IBM® C/C++ for MVS™. It is highly recommended to choose the new syntax, especially for customers who do not have IBM C/C++ for MVS installed or who do not have any dependency on the old syntax. The new syntax allows more flexibility. Refer to the z/OS XL C/C++ Compiler and Runtime Migration Guide for the Application Programmer for more information.
(Optional) You can supply your runtime options for the compiler by modifying variable CBCRTOPT. To use Japanese compiler messages, change NATLANG(ENU) to NATLANG(JPN).
(Optional) Specify C compiler options in the CBCCCOPT parameter.
(Optional) Specify C++ compiler options in the CBCCXOPT parameter.

The members in the following table reside in the CBC.SCCNPRC data set.

The IBM-supplied cataloged procedures provide many parameters to allow each site to customize them easily. The table below describes the commonly used parameters. Use only those parameters that apply to the cataloged procedure you are using. For example, if you are only compiling (EDCC), do not specify any binder parameters.

Parameter	Description
INFILE	For compile procedures, the input z/OS® XL C/C++ source file name, PDS name of source files, or directory name of source files. For IPA Link procedures (for example, EDCI, and CBCI), the input IPA object. For prelink, link and bind procedures, the input object. If you do not specify the input data set name, you must use JCL statements to override the appropriate SYSIN DD statement in the cataloged procedure.
OUTFILE	Output module name and file characteristics. For the cataloged procedures ending in a link-edit, bind or go step, specify the name of the file where the load module is to be stored. For most other cataloged procedures, specify the name of the file where the object module is to be stored. If you do not specify an OUTFILE name, a temporary data set will be generated.
CPARM	Compiler options: If two contradictory options are specified, the last is accepted and the first ignored.
STDLIBSD	Enables procedures that contain a bind or prelink/link step to use C128N (NOXPLINK version of the C++ Standard Library).
BPARM	Bind utility options: If two contradictory options are specified, the last is accepted and the first ignored. The set of default binder options passed on the binder invocation does not include COMPAT=CURRENT. The COMPAT option is omitted so the binder default, which is COMPAT=MIN, is used unless it is explicitly overridden by specifying it with the BPARM proc option.
IPARM	IPA link step options: If two contradictory options are specified, the last is accepted and the first ignored.
PPARM	Prelink utility options: If two contradictory options are specified, the last is accepted and the first ignored.
LPARM	Linkage-editor options: If two contradictory options are specified, the last is accepted and the first ignored.
GPARM	Language Environment runtime (Go step) options and parameters: If two contradictory Language Environment runtime options are specified, the last is accepted and the first ignored.
CRUN	Compile step execution runtime parameters for the z/OS XL C/C++ compiler.
IRUN	IPA link step runtime parameters: for the z/OS XL C/C++ compiler.
OPARM	Object Library Utility parameters. Required for EDCLIB.
OBJECT	Object module to be added to the library. The data-set name (DSN=...) and any applicable keyword parameters (such as, DCB, DISP,) can be specified using this parameter. The default is OBJECT=DUMMY. OBJECT is required for EDCLIB if the ADD function is selected.
LIBRARY	Data-set name for the library for the requested function (ADD, DEL, MAP, or DIR). An example is `LIBRARY='FRED.LIB.OBJ'.` LIBRARY is required for EDCLIB and EDCCLIB.
MEMBER	Member of the library to contain the object module. An example is `MEMBER='MYPROG'`. In z/OS XL C, MEMBER is required for EDCCLIB.
