How to prevent newline in console?

I'm trying to print a countdown in the console without having each digit in the countdown go to the new line. In other words, I want it to say something like 3-2-1 with each new number overwriting the last.

Is this possible?

In some consoles it's \r followed by a comma for example.

Anything like that here?

Thanks for any help.

Why don't you clear console each time a new digit is printed?
You have to print everything else, too, that's clear, but it's a workaround.

Good point, I could do that, but there's info I'd like to keep on the screen if possible.

Definitely no big deal, as you say I can redraw the whole console easily enough.

After some more experimentation I found a small problem with using CLS to clear the whole console and then reprint everything: cls makes the title and stats (if showing) blink...

The current implementation of 'print' command does not support any special (escaped) characters and always outputs a new line.
