Abend, this is the short form of ” abnormal end ” . This abend is a type of unexpected or abnormal end of a process. If I talk about computer software, it means software crashes, when a program stops unexpectedly.
For example, an error can freeze or crash in the code of a program when it is running one of the commands. As a result, the program running has an unexpected (and it is mostly inconsequential) end.
This term ” abend ” was first used in IBM OS / 360 system on the basis of an error message. But now it is used by Novell Network Systems and together it has also become a common programming term.
