RANDOM_NUMBER(3I)				       Last changed: 1-6-98

NAME
     RANDOM_NUMBER - Returns pseudorandom numbers

SYNOPSIS
     CALL RANDOM_NUMBER ([HARVEST=]harvest)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     Fortran 90

DESCRIPTION
     The RANDOM_NUMBER intrinsic subroutine returns one pseudorandom number
     or an array of pseudorandom numbers from the uniform distribution over
     the range 0 <= x < 1.  It accepts the following argument:

     harvest   Must be of type real.  It is an output argument.	 It may be
	       a scalar or an array variable.  It is set to contain
	       pseudorandom numbers from the uniform distribution in the
	       interval 0 <= x < 1.

	       On UNICOS and UNICOS/mk systems, harvest is 64 bits.  On
	       IRIX systems, harvest is 32 bits.

     The name of this intrinsic cannot be passed as an argument.

EXAMPLES
	  REAL	X,  Y(10,10)
	  ! Initialize X with a pseudorandom number
	  CALL RANDOM_NUMBER(HARVEST=X)
	  CALL RANDOM_NUMBER(Y)
	  ! X and Y contain uniformly distributed random numbers
