Delete last two lines of stdout using c shell?

Question

I want to create a little animation in the stdout of the terminal using printf. So far I figured out how to replace the last line with

#!/bin/csh -f        
printf "text1"
printf "text2"
sleep 1
printf "\r replaced text2"

How do I replace both lines?

printf "\r\r replace text1"

does not work....

Answer 1

You need to use the cuu1 terminfo capability to move the cursor up.

printf "foobar"
tput cuu1
printf "baz"

Answer 2

Ignacios answer brought me on the right track! Thanks!! Nevertheless:

    tput cuu N

sets your cursor N lines back.
