Customizing the cataloged procedures

You can tailor the cataloged procedures supplied with Language Environment to suit the needs of your site. The procedures are part of the SCEEPROC cataloged procedure library.

You can tailor any of the following:

If your site uses a prefix other than the IBM-supplied one, you can modify the data set name prefixes by using the LIBPRFX parameter.
If you place CEE.SCEERUN and CEE.SCEERUN2 in the LNKLSTxx concatenation during installation, remove the STEPLIB DD statements.
Note: Since SCEERUN2 contains module names that do not intersect with any pre-Language Environment runtime library or any existing library, IBM® recommends that SCEERUN2 be added to the LNKLST. This will not result in any adverse effects.
If most of the programs at your site require a larger region for successful execution, change the default region size for the GO steps.
Change UNIT=SYSDA in CEEWL, CEEWLG, AFHWL, AFHWLG, AFHWN, AFHWRL, and AFHWRLG.
Tailor your TSO/E LOGON procedure. If you plan to run Language Environment applications under TSO/E, add SCEERUN and SCEERUN2 to the STEPLIB DD of the LOGON procedure, or use the TSO/E command TSOLIB to allocate SCEERUN and SCEERUN2; this is unnecessary if you place SCEERUN and SCEERUN2 into the LNKLST concatenation during installation.
For programs that require the Language Environment® Prelinker Utility, see z/OS Language Environment Programming Guide and z/OS XL C/C++ Programming Guide for details on changes to link-edit procedures. The requirement to use the Prelinker has been eliminated because the Binder directly supports input from the Language Environment conforming compilers. By choosing to eliminate usage of the Prelinker, the executable program will be a program object and must reside either in a PDSE or a UNIX file system.
