PURPOSE
       sasum  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
                 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.
