Abnormal End


The term “Abnormal End”, often abbreviated as ABEND, refers to an unexpected or sudden termination or ending of a process or program due to some error or problem. It is a term commonly used in mainframe computing to denote a software crash or failure. An Abnormal End can disrupt ongoing operations and may result in data loss or corruption.


The phonetic pronunciation of “Abnormal End” is: æbˈnɔrməl ɛnd


Abnormal End, also known as ABEND, is an important term in the technology sector because it indicates an unexpected or abnormal termination of a software program or process. This usually occurs due to some error, bug, or fault that the system cannot handle or recover from.

ABEND informs programmers or system administrators who then need to debug and resolve the issue, ensuring the system functions well. Understanding ABENDS helps to enhance the quality and reliability of the software, minimize system crashes, and improve overall user experience. Efficient handling of such abnormal terminations can cause substantial cost savings by reducing system downtime.


An “Abnormal End”, also known as ABEND, primarily serves as an identifier for software or system failures. This term finds its roots in mainframe programming, being widely employed to refer to any abnormal termination of a process or program.

The main function of this operational alert is to flag out issues within a computing system that leads to the unexpected cessation of a process, be it due to an internally identified issue by the system or due to an external intervention by the user.The purpose of ABEND is to aid in troubleshooting and diagnosing the cause of system errors for system developers, administrators, or maintainers. Upon detection of a malfunction or irregularity,

ABEND will cause the system or program to halt rather than permitting it to produce erroneous results or corrupt the system further. Typically sufficient data about the state of the program at the time of failure is preserved which enables debugging and aids in identifying the cause of the problem. When an ABEND is triggered, it helps maintain the integrity of the system’s data and also contributes in preserving the state of the system pre-termination for an informed diagnosis and precise rectification.


1. Failed Bank Transaction: Suppose you’re trying to make an online bank transfer. You fill in all the necessary details and hit ‘submit’, but an error message pops up saying the transaction could not be completed. This is an example of an abnormal end where the transaction process couldn’t complete its regular flow because of an unknown error or network issue.

2. Unexpected Software Crash: As another example, imagine you’re working on a critical report on software like Microsoft Excel or Word, and the application suddenly crashes without any warning, and you lose all unsaved work. This abrupt halt or crash of applications is an instance of abnormal end.

3. Auto-Cancelled Online Order: Suppose you are shopping online and you add a couple of items to your cart and proceed to checkout. You enter your shipping details and go to the payment gateway, but suddenly the page crashes and when you reload it, your order has been automatically cancelled. This is an example of an abnormal end in an e-commerce context.

Frequently Asked Questions(FAQ)

Q1: What does the term “Abnormal End” mean

A1: The term “Abnormal End”, often abbreviated as “ABEND”, is a term used in computing to signify an abnormal termination of a software program or system. It arises when the program encounters an error or a significant unexpected condition it wasn’t designed to handle.

Q2: What are some common causes of an Abnormal End?

A2:Various reasons can cause an Abnormal End, such as software errors, system bugs, hardware malfunctions, improper data input, or due to running out of resources like memory or storage.

Q3: How does an Abnormal End affect the software or system involved?

A3:An Abnormal End can disrupt the normal functioning of software or a system. It can lead to the loss of unsaved data, interruption of services, or even damage to the system in severe cases.

Q4: How can an Abnormal End be resolved?

A4: Abnormal Ends can usually be resolved through a combination of debugging, system updates, data corrections, or hardware fixes. It’s crucial to identify the source of the error, replicate it, and then apply necessary solutions.

Q5: Is an Abnormal End a serious issue?

A5: The seriousness of an Abnormal End depends on its cause and the system it occurs in. In a critical system, even a minor Abnormal End can be of great concern, while in less critical systems, they might only cause minor annoyance.

Q6: What steps can we take to prevent Abnormal Ends?

A6: Preventing Abnormal Ends primarily involves rigorous software testing, ensuring correct data input, keeping the system hardware and software up-to-date, and ensuring proper system maintenance and effective error handling procedures.

Q7: Do Abnormal Ends only occur in specific systems or programming languages?

A7: No, Abnormal Ends can occur in any system or program if it encounters an erroneous condition or bug. They are not exclusive to any specific systems or programming languages.
