Subject: Re: Newbie question- Return method

The word "return" is a reserved word in ruby, just like the words
"def", "if", "while", etc...

"return" is used in a method to exit the method and to return the
given value to the caller.  In principal, you could write

def compute_square(x)
  return x*x
end

...although The Ruby Way(tm) would be to simply write:

def compute_square(x)
  x*x
end

since, by the definition of the language, the return value of a method
is (99.99% of the time) the last expression computed in the method.
