Coding in RPG (IBM i/AS400). Using ON-EXIT.

I wonder if you know that there is a way for capture errors using the ON-EXIT opcode. This is not a monitor replacement, because with monitor we have more control over our code execution, but in some cases, is great to have the possibility of cleaning our work before the program ends because an unexpected error.
In this video, I show you an example of how to do it.

Please, let me know what you think about it. Leave your comments below.
