Whether or not you want to use asm is not relevant. It's what you do with it that matters. I mean, exactly what you said above would apply equally if you wanted to write the code in pascal.

Why would [ref] be needed to use asm?

Is there any known use case other than the one demonstrated by FreeAndNil, namely to allow modification of a const param?

McAfee, like so many AV products, the cure is worse than the disease.

Isn't this a well documented file system for which there are multiple open source projects that you can use to support the documentation? More generally, I'd advise you to put more effort into asking questions. Time spent describing what your problem is, what you already know, where you are blocked, etc. is effort you should spend if you want to get something in return.

Doesn't sound like it's not that exceptions aren't handled. App exiting is entirely different. How about the details we asked for.

Or maybe floating point exceptions are masked so there is no exception. We can't see your code, or know what version you use.

That makes a lot more sense. Assumed it was common knowledge? I'm not so sure. I think there's still a big underbelly of Delphi coders that don't get this.

My point is that it's behaviour that you don't ever need to know because the correct way to handle byte data is as, well, bytes and not text. So for sure there's an algorithm, but it's not one that anyone actually needs to know.

This way is reliable and works

I mean, you work with strings and do TEncoding.ASCII.GetBytes

I don't see this as helpful to anyone. Use bytes to represent bytes. Use strings to represent text. Don't use ANSI strings.

What is wrong with the world of Delphi programmers that in 2025 there are still people who can't understand the difference between text and bytes? The article you link to goes on and on about text but your data is bytes. Why not just use the correct data type?

Now we are discussing what the cheap and rubbish version of ChatGPT says about Delphi?
