Better, but there are still issues: For one you need to look at your
formatting. I think there are a number of blanks missing. You also
start re-flowing existing text a little too early (but that's minor, it
just makes the diff bigger than it needs to be). And then you add
mention of "tword" which I think you mean to be "tbyte".

Also - please don't top-post.
