          ISEED is 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\&.

  This routine uses a multiplicative congruential method with modulus
  2**48 and multiplier 33952834046453 (see G\&.S\&.Fishman,
  'Multiplicative congruential random number generators with modulus
  2**b: an exhaustive analysis for b = 32 and a partial analysis for
  b = 48', Math\&. Comp\&. 189, pp 331-344, 1990)\&.

  48-bit integers are stored in 4 integer array elements with 12 bits
  per element\&. Hence the routine is portable across machines with
  integers of 32 bits or more\&.
