Thank you kindly for your response. Are the spaces, which I highlighted with carrots, the whitespace (or comment) allowed by the /x? If so, is the function of the () and [] to delineate the content? How might it appear without the /x? What part of this is saved in $1? Do you qualify the use of chomp since you used \z?
