Determines the Language Environment thread abnormal termination behavior. When the value of _EDC_PTHREAD_BACKOUT is set to YES, Language Environment requests backout processing from the Resource Recovery Services component for in-flight units of recovery. The request is made only when an abend or program check is the reason for termination and Resource Recovery Services are active in the environment.
Requests for backout will not occur for any other value of _EDC_PTHREAD_BACKOUT. The default behavior is equivalent to setting _EDC_PTHREAD_BACKOUT = NO.
