Key/101 User Exit Programs
Key/101 user exit programs provide a method to invoke user-written on-line and batch-mode application programs for each record in a batch at strategic points in the data entry process. Exits are rarely needed, but they can add extra security and flexibility by performing such functions as:
- On-line file updates
- Database access
- Interfacing with a security system
The Format Display utility provides all information needed to integrate a user exit program in an application.
