All authorized commands written in the REXX language must be loaded
from a VSE Librarian sublibrary specified on the SETSYS AUTHCLIB command.
These may be both IBM and customer (or vendor) supplied.
All authorized execs must be loaded from a VSE Librarian sublibrary
specified on either the SETSYS AUTHCLIB or SETSYS AUTHELIB commands.
These may be both IBM and customer (or vendor) supplied.
User execs that are not authorized but are being shared by all
REXX/CICS users can be placed in a VSE Librarian sublibrary specified
in the LIBDEF PROC search chain for the CICS partition.
Note: - The AUTH option of the DEFCMD or DEFSCMD is itself an authorized
command option. That is, AUTH may only be used if the user issuing
it is an authorized user or if it was issued from an exec loaded from
an authorized sublibrary.
- The EXECLOAD and EXECDROP commands are authorized. Therefore,
only an authorized user or exec can EXECLOAD an exec from an authorized
sublibrary.
