Understanding *PSSR in IBM i AS400
In this video, viewers gain insights into the *PSSR (Program Status Save Routine) in the IBM i (AS/400) environment, particularly its relevance for RPG and CL programmers.
In this video, viewers gain insights into the *PSSR (Program Status Save Routine) in the IBM i (AS/400) environment, particularly its relevance for RPG and CL programmers.
- Definition of *PSSR: The *PSSR is a special routine that is invoked when an unhandled exception occurs in a program. It allows developers to manage errors gracefully.
- Importance in Error Handling: The video emphasizes how *PSSR captures error information, logs it, and performs necessary cleanup operations before the program terminates.
- Implementation: Viewers learn how to define a *PSSR routine in their RPG or CL programs, including the syntax and structure required to set it up effectively.
- Best Practices: The video covers best practices for using *PSSR, such as ensuring that critical resources are released and that user-friendly error messages are provided.
- Examples: Practical examples demonstrate the implementation of *PSSR in real-world scenarios, showcasing how it prevents data loss and improves program reliability.
- Common Pitfalls: The presenter discusses common mistakes programmers make when using *PSSR and how to avoid them.
