Subject: Re: Basic question about blocks

Josh,

Sorry for mistake in typing the code...below is the program code...

--------------------------------------------
# Script block1.rb
def animals
       yield "Tiger"
       yield "Giraffe"
end

animals { |x| puts "Hello, #{x}" }
animals { |x| puts "It's #{x.length} characters long!" }
--------------------------------------------


And the Yield function in above ...
- first yields to the .... animals { |x| puts "Hello, #{x}" } for
"Tiger"
- then the same "Tiger" should go to the ... animals { |x| puts "It's
#{x.length} characters long!" }

.... this is my understanding...but the code prints out as below:

Hello, Tiger
Hello, Giraffe
It's 5 characters long!
It's 7 characters long!

...Meaning the
- first animals block executes for the word "Tiger" and "Giraffe"
FOLLOWED BY
- second animals block executes for the word "Tiger" and "Giraffe"
