NAME
     sasum - Return the sum of the absolute values of a vector x.

SYNOPSIS
     REAL FUNCTION SASUM (N, X, INCX)

     INTEGER INCX, N

     REAL    X( * )



     #include <sunperf.h>

     double sasum(int n, float *sx, int incx) ;

PURPOSE
     SASUM - Return the sum of the absolute values of x  where  x
     is an n-vector.


PARAMETERS
     N         - INTEGER.
               On entry, N specifies the number  of  elements  in
               the  vector.   N must be at least one for the sub-
               routine to have any visible effect.  Unchanged  on
               exit.

     X         - REAL array of DIMENSION at least
               ( 1 + ( m - 1 )*abs( INCY  )  ).   On  entry,  the
               incremented  array X must contain the vector x. On
               exit, X is overwritten by the updated vector x.

     INCX      - INTEGER.
               On entry, INCX specifies  the  increment  for  the
               elements  of  X. INCX must not be zero.  Unchanged
               on exit.
