Note the following restrictions when using NUCLSTxx:
- Multiple CSECT load modules must be link-edited with the scatter
(SCTR) attribute of the linkage editor before they can be added to
the nucleus region. If this is not done, the system enters a non-restartable
wait state at system initialization.
- Do not use NUCLSTxx to load or delete an alternate nucleus (IEANUC0x).
You can select an alternate nucleus member by specifying the suffix
identifier of the alternate IEANUC0x member on either the NUCLEUS
statement in the LOADxx member of SYS1.PARMLIB, or on the LOAD parameter
during system initialization. For more information, see Specifying an alternate nucleus.
