Maybe this one should be in the FAQ; I know it came through here
several months ago, but I forgot the answer until, of course, I
wanted to do it myself.

Now I have a workaround, so I'm interested in the answer only
for academic reasons (until I need to do it again...); if I have
some (csh) variable foo and I want awk to recognize it, e.g.
awk file '{print $1-?$foo?}', what would I use instead of ? and ? ?
Thanks!
