Abnormal end
An AbEnd (also abnormal end or abend) is an abnormal termination of software, or a program crash.
This usage derives from an error message from the IBM OS/360, IBM zOS operating systems. Usually capitalized, but may appear as "abend". The most common were ABEND 0C7 (Data exception) and ABEND 0CB (Division by zero).[1] Abends could be "soft" (allowing automatic recovery) or "hard" (terminating the activity).[2]
Errors or crashes on the Novell NetWare network operating system are usually called ABENDs. Communities of NetWare administrators sprung up around the Internet, such as abend.org.
The term is jocularly claimed to be derived from the German word "Abend" meaning "evening".[3]
