Subject: |how do you know when to put a variable between pipes?|

Hi i am at about page fifty in the pickaxe book, and i have a
question.  I see a lot of examples of a block that starts with |
SomeVar| and I dont really understand how you know when you can do
this or what the value will be that is passed to the variable.  What
is the name of  this construct or the var that goes in pipes?  Thank
you :)
