Set Optional to the Parameters in Sproc

I would like to know whether we can set the parameter in Sproc to be an optional. The values that passed from VB or Access to the sproc can be ignore when this option has been set. Like in Vb or VBA, the function that we create or declare can define the variables either optional or compulsory. Does anyone know this?????

CREATE PROC yourproc
  @mandatory varchar(10),
  @optional int = NULL
AS
  SELECT @mandatory, @optional
GO

try usage:
EXEC yourproc 'testing', 10
EXEC yourproc 'testing'
EXEC yourproc ----> error, proc expects value for parameter @mandatory
