+/*  ======= */
+
+/*  DLARNV returns a vector of n random real numbers from a uniform or */
+/*  normal distribution. */
+
+/*  Arguments */
+/*  ========= */
+
+/*  IDIST   (input) INTEGER */
+/*          Specifies the distribution of the random numbers: */
+/*          = 1:  uniform (0,1) */
+/*          = 2:  uniform (-1,1) */
+/*          = 3:  normal (0,1) */
+
+/*  ISEED   (input/output) INTEGER array, dimension (4) */
+/*          On entry, the seed of the random number generator; the array */
+/*          elements must be between 0 and 4095, and ISEED(4) must be */
+/*          odd. */
+/*          On exit, the seed is updated. */

+/*          The number of random numbers to be generated. */

+/*  real numbers from a uniform (0,1) distribution, in batches of up to */
+/*  128 using vectorisable code. The Box-Muller method is used to */
