accessing local variable in nested block in ruby

I have a scenario

func1 do 
  x='abc'
  func2 do
    puts x
  end
end

for this I get x = nil. Why is it so, and how to access external variable like x in inner block.

You will get "abc" only if func1 and func2 executes blocks you are passing to them (yielding or calling).

Check out an example

def func1
end

def func2
end

func1 do
  x = "Hello World"
  func2 do
    puts x
  end
end
#=> nil

def func3
  yield
end

def func4
  yield
end

func3 do
  x = "Hello World"
  func4 do
    puts x
  end
end
#=> Hello World
