Subject: New to Ruby.  Specific syntax question.

I'm reading through the PickAxe book right now.  I'm new to programming,
and more specifically, Ruby.

Right now I'm looking at a line that says this:
fib_up_to(1000) {|f| print f, ""}

I'm curious about the parts of this statement.

I know that "fib_up_to(1000)" passes 1000 into this specific method.

The thing that gets me confused is the block statement (right
terminology?).  What's the "|f|"?  I know "print f" says to print this
variable.  Then, what're the quotes for?

Is a variable "f" created in this block, then told to print, and more
specifically, told to print into the parentheses?

I'm new, so sorry if this is a hang-up.  I just want to understand.

Thank you.
