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!

Hello,

> nothing.

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.

Cheers,
