  Parameters:

  pc - Page context in which the configuration variable is to be looked up

  name - Configuration variable name

  scope - Scope in which the configuration variable is to be looked up

  Returns:

  The java.lang.Object associated with the configuration variable, or null if it is not defined.

  Returns:

  The java.lang.Object associated with the configuration variable, or null if it is not defined.
