User-replaceable programs and the storage protection facility
When you are running CICS with the storage protection facility, there are two points
you need to consider:
v The execution key in which your user-replaceable programs run
v The storage key of data storage obtained for your user-replaceable programs.
Execution key for user-replaceable programs
When you are running with storage protection active, CICS always gives control to
user-replaceable programs in CICS key. Even if you specify EXECKEY(USER) on
the program resource definition, CICS forces CICS key when it invokes the
program. However, if a user-replaceable program itself passes control to another
