EQA2456I Returning from enclave where z/OS® Debugger was initialized. Handling of non-LE events has been suspended. Debugging of non-LE programs is suspended in this z/OS Debugger session.

Explanation
The Language Environment® was invoked with
TEST/NOPROMPT or NOTEST causing z/OS Debugger to be
initialized during an enclave that was not the top enclave. The enclave in which z/OS Debugger was initialize is now terminating. z/OS Debugger will no longer intercept non-Language
Environment events and, therefore, you can no longer
debug non-Language
Environment programs.

Programmer response
If you do not need to debug higher-level, non-Language
Environment programs or to intercept non-Language
Environment events, no action is required. Otherwise,
re-run the job without NOPROMPT or with the CALL to CEETEST, PLITEST or ctest() in a higher-level
enclave.
