       void csscal_64(long n, float alpha, complex *y, long incy);



PURPOSE
       csscal  Compute  y  := alpha * y where alpha is a scalar and y is an n-
       vector.


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.


       ALPHA (input)
                 On entry, ALPHA specifies the  scalar  alpha.   Unchanged  on
                 exit.


       Y (input/output)
                 (  1  +  ( n - 1 )*INCY ).  On entry, the incremented array Y
                 must contain the vector y. On exit, Y is overwritten  by  the
                 updated vector y.


       INCY (input)
                 On entry, INCY specifies the increment for the elements of Y.
                 This routine returns immediately if  INCY  is  less  than  or
                 equal to zero.  Unchanged on exit.
