Well, I don't think parameter expansion does affect scrolling of the screen.

Only complaint now is that when the question is asked at the very bottom of the window the cursor still jumps to the next line, the window scrolls but the cursor jumps back to the end of the question. That can be avoided by using read -n 1 - as wisecracker suggested - but I like to use the Enter key to confirm.

Does it run the same way on your system?
No, it doesn't. In my terminal emulator, it asks and stays on the very last line, even when reading / getting the <Return> /<Enter> key. But, as we learned, emulators may behave differently.

I mean that it makes for a shorter script.

Interesting. I thought the newline was unavoidable because it takes the Enter key to terminate the read call.
