Ok, I'll stick to /\\/ instead of "\\", but the following still puzzles 
me.

this works ...
echo ")" | awk '{print $0; gsub(/)/, "b"); print $0;}'

this doesn't ...
echo "(" | awk '{print $0; gsub(/(/, "b"); print $0;}'



It works with /\(/ and /\)/, but why does /)/ works and not /(/ ?


Thanks,
Jeff.
