Tailoring the cataloged procedures and CLISTs to your site

Several cataloged procedures and CLISTs are supplied with Language Environment® and the Language Environment-conforming compilers. Some of these contain data set names that you may need to customize to your installation.

For information to help you customize the Language Environment cataloged procedures, see the topic discussed in Customizing the cataloged procedures and the list in Table 1.

For a list of names and possible modifications of CLISTs and all other cataloged procedures, see Table 1.

Several Fortran and C library routines have identical names. To correctly run existing Fortran applications under Language Environment, it is necessary to resolve all name conflicts. The Language Environment interface validation exit is a routine that automatically resolves conflicting library routine references within Fortran routines.

If the possibility exists of bringing in a Fortran routine when link-editing, activate the binder interface validation exit by modifying each of the cataloged procedures in Table 1 that performs a link-edit step to add an LKED parm of EXITS(INTFVAL(CEEPINTV)), and provide the following DD statement in the same step:

//STEPLIB DD DSN=CEE.SCEELKED,DISP=SHR

For more information about resolving conflicting names, see z/OS Language Environment Programming Guide.

Category	Procedure names	Possible modifications
C/C++ cataloged procedures	Procedures found in hlq.SCCNPRC data set.	Modify the procedures to use the release of Language Environment you are using.
COBOL cataloged procedures	IGYWC IGYWCG IGYWCL IGYWCLG IGYWCPG IGYWCPL IGYWCPLG IGYWPL	Modify the procedures to use the release of Language Environment you are using.
PL/I cataloged procedures	IEL1C IEL1CG IEL1CL IEL1CLG	Modify the procedures to use the release of Language Environment you are using.
Language Environment CLISTs	CMOD CPLINK C370LIB GENXLT ICONV DLLRNAME	If you are not using the IBM-supplied default data set prefix, change the data set prefix symbolic parameter in all CLISTs. Change parameters in CLISTs to match values at your site. These procedures can be found in the CEE.SCEECLST data set.
