What is the Ruby Shell and how do i get to it

I am using Ruby 1.84 19 installed on a Windows XP home edition machine.
I am using the pragmatic programmers book “Agile development with
Rails”. The book asks me to access the “ruby shell”. Being a newbie,
what is the Ruby shell? and how do i access it on windows?

In a command windows write irb (short for interactive ruby) or use the
menu option of fxri on the ruby menu Start Button > All Programs > Ruby

I imagine it is talking about irb. Type irb on the command line.
