Loader domain exits XLDLOAD and XLDELETE
There are two global user exits in the loader domain. XLDLOAD is invoked when a
new instance of a program is loaded into storage, before the program is made
available for use.
XLDELETE is invoked after an instance of a program is released by CICS and
before the program is freed from storage.
For LPA-resident programs, the exits are still invoked when a program is acquired
or released, even though the program is not physically loaded or freed.
These are both information-only exits. Any changes made to the exit parameters by
the exit program are ignored by CICS, as is any return code which it sets.
