Itis also referred to as a routine written by a user to take control at an installation exit of an IBM software product.
A computerprogram has two primary routine types (function and subroutine) that are used to handle multiple commands. When a condition requires an immediate exit, an exit routine command is implemented to interrupt the code sequence execution and end the application after the computer processes the command.
An installation exit routine is also known as an exit program.
Example of usage – “A programmer must consider randomly occurring conditions or events and perform code changes as required. Thus, additional exit routine commands are added to stop sequential command execution.”
