Sorry...

Global variables begin with $

irb(main):001:0> def a_method
irb(main):002:1> puts $global_var
irb(main):003:1> end
=> nil
irb(main):004:0> a_method
nil
=> nil
irb(main):005:0> $global_var = "Hi, there. I'm a global"
=> "Hi, there. I'm a global"
irb(main):006:0> a_method
Hi, there. I'm a global
=> nil

Sorry.. I had a brain fart.. was thinking of methods.. should have read
more carefully..

irb(main):001:0> $global_var = "global!"
=> "global!"
irb(main):002:0> global_variables.grep /global_var/
=> ["$global_var"]
irb(main):003:0>
