awk -v -- Why doesn't my example work?

Hi. I've been playing around a bit. This isn't for any practical purpose-- it's really just a theoretical exercise. I wrote this little thing:

Code:

foreach num ( 6 5 4 )
awk -v "number=$num" 'BEGIN{for(x=0;x<$number;x++) printf "-"; printf "\n"}'
end

I would expect the following output:

Code:

------
-----
----

But I get nothing but blank lines. The awk -v is still a little odd to me-- I can generally use it, but once in a while, its behavior seems anomalous. Anyway, what am I doing wrong?
