Difference Between SP with BEGIN/END and without BEGIN/END

I have found some SP(stored procedure) written as,

CREATE PROCEDURE [dbo].[XXX]
(
   -- Parameters
)
BEGIN

--- Actual Work

END

and some as

CREATE PROCEDURE [dbo].[XXX]
(
   -- Parameters
)

--- Actual Work

What makes it difference?

There is no real difference. Create procedure syntax specifies BEGIN and END as optional. And it makes sense since CREATE PROCEDURE statement cannot be combined with other statements in a single batch.
