Why do we use *INLR = *ON in RPGLE as400 (IBM i)

This video delves into the significance of the *INLR (Last Record Indicator) in RPGLE programming.

• Understanding *INLR: The video begins by explaining what *INLR is and its role in RPGLE programs. It highlights that setting *INLR to *ON indicates that the program is finished processing and allows for resource cleanup.
• Resource Management: Viewers will learn how *INLR helps in managing resources effectively, ensuring that files are closed and memory is released when the program ends. This is crucial for maintaining system performance and avoiding memory leaks.
• Program Lifecycle: The video outlines the lifecycle of an RPGLE program, emphasizing the importance of the *INLR indicator in the context of program termination and resource deallocation.
• Best Practices: The presenter shares best practices for using *INLR, including scenarios where it should be set to *ON and potential pitfalls of neglecting it.
• Examples: Practical examples are provided to illustrate the correct implementation of *INLR in RPGLE code, showcasing how it affects program behavior and resource management.
• Common Mistakes: The video also addresses common mistakes programmers make regarding *INLR and how to avoid them to ensure optimal program performance.

Overall, this video serves as a valuable resource for RPG/CL programmers looking to enhance their understanding of program termination and resource management in the IBM i environment.
