   C INTERFACE

       double dzasum(int n, doublecomplex *x, int incx);

       double dzasum_64(long n, doublecomplex *x, long incx);



PURPOSE
       dzasum Return the sum of the absolute values of the elements of x where
       x is an n-vector.  This is the sum of the absolute values of  the  real
       and  complex  elements  and  not the sum of the squares of the real and
       complex elements.


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
                 array X must contain the vector x.  Unchanged on exit.


       INCX (input)
                 On entry, INCX specifies the increment for the elements of X.
                 INCX must not be zero or negative.  Unchanged on exit.
