Morning Stefan,

it even

I agree. It *should* only be used in those cases when you don't care if an error occurs or not. I've used it myself, but documented the code with a comment to make sure anyone reading it knows *why* I used it and why I don't care. Having said that, I don't use it very often.

Having been a developer (many languages, many systems) over the years, I find the 'when others null' discussion quite interesting and very similar to 'do not ever use a GOTO in your code'. Unfortunately, there are good reasons for both - IMHO. I use GOTOs about as frequently as WHEN OTHERS THEN NULL. Regards,
