  31  *     "The error INVALID_ENUM is generated if <target> specifies a
  32  *      nonexistent program target or a program target that does not
  33  *      support program local parameters.  The error INVALID_VALUE is
  34  *      generated if <index> is greater than or equal to the
  35  *      implementation-dependent number of supported program local
  36  *      parameters for the program target."
