Any registered user-written condition handlers not unregistered by CEEHDLU, are unregistered automatically by the system upon removal of the associated call stack entry from the call stack.
If the specified procedure is registered more than once, the most recent registration is removed. Earlier registrations remain in the queue for the call stack entry.
The message CEE0257 occurs if the pointer contained in procedure is not a procedure pointer.
