Hey,

I am new to ruby. I have the following simple ruby script
def make_show_name(show)
return Proc.new {|host| show + " with " + host}
end
show = make_show_name("Practical Cannibalism")
show.call("H. Annabellector")

when run this using irb, it prints out: Practical Cannibalism with H.
Annabellector
but when I saved this as test.rb and type ruby test.rb, it prints out
nothing.

What is the problem here?

Thanks!

irb automaticaly prints out the value of the last expression, but your
script does not.

Try

puts show.call("H. Annabellector")

and it should be fine.
