SYNOPSIS
       DOUBLE PRECISION FUNCTION DASUM(N, X, INCX)

       INTEGER N, INCX
       DOUBLE PRECISION X(*)

       DOUBLE PRECISION FUNCTION DASUM_64(N, X, INCX)

       INTEGER*8 N, INCX
       DOUBLE PRECISION X(*)

   F95 INTERFACE
       REAL(8) FUNCTION ASUM([N], X, [INCX])

       INTEGER :: N, INCX
       REAL(8), DIMENSION(:) :: X

       REAL(8) FUNCTION ASUM_64([N], X, [INCX])

       INTEGER(8) :: N, INCX
       REAL(8), DIMENSION(:) :: X

   C INTERFACE
       #include <sunperf.h>

       double dasum(int n, double *x, int incx);

       double dasum_64(long n, double *x, long incx);

PURPOSE
       dasum  Return  the sum of the absolute values of x where x is an n-vec‐
       tor.

ARGUMENTS
       N (input)
		 On entry, N specifies the number of elements in  the  vector.
		 N must be at least one for the subroutine to have any visible
		 effect.  Unchanged on exit.

       X (input)
		 ( 1 + ( n - 1 )*abs( INCX ) ).	  On  entry,  the  incremented
