passing Proc as a parameter

[Can Ceran]

Hi,
I'm a new user of Ruby, and trying to learn its features. But I have a
difficulty to understand Proc class.
What will be the referencing environment when we pass Proc as a
parameter?
and other question, how can we pass Proc as a parameter, can you give an
example of it?
Thanks for your help.
