You can give that variable as a method parameter, as shown in the example below:

def main_program
  my_variable = 3
  other_method(my_variable)
end

def other_method(special_variable)
  # do something with the special-variable
end

A nice read on how to define and call methods can be found in the Ruby programming wiki

Can i also give two variables? Like other_method(var1)(var2)?

@saigkill yes, you can, other_method(var1, var2). I advice you to start from some basics before you start programming in Ruby.

@saigkill Marek is right. I've updated my answer with a link explaining methods in ruby. I hope that helps :)
