Subject: Re: How to suppress display of specific code in irb??

Thanks these all did the trick. I especially like the toggle.

However even after finding the solution I still could not find where any 
of this is documented.

I would like to see an explanation of "string"; null.

I find that adding only a semicolon (no nil)does the trick
doc = Nokogiri::HTML(open(url)); # produces no display


Can you point me to some documentation than may explain the solutions, 
so I know where to look next time.

Thanks
