Bob Rogers is a consulting engineer with Trident Services. But even IBM couldn't provide everything customers needed in an operating system. One stopgap was to let customers provide some of their own programming at specific points in the processing.

This approach has several drawbacks, but in the beginning, it was absolutely required. Unfortunately, it has persisted and customers or ISVs can take advantage of hundreds of exit points to customize the operation of their systems.

The exit code must interact intimately with the
