NAME
       DLASQ6  -  compute one dqd (shift equal to zero) transform in ping-pong
       form, with protection against underflow and overflow

SYNOPSIS
       SUBROUTINE DLASQ6( I0, N0, Z, PP, DMIN, DMIN1, DMIN2, DN, DNM1, DNM2 )

	   INTEGER	  I0, N0, PP

	   DOUBLE	  PRECISION DMIN, DMIN1, DMIN2, DN, DNM1, DNM2

	   DOUBLE	  PRECISION Z( * )

PURPOSE
       DLASQ6 computes one dqd (shift equal to zero)  transform	 in  ping-pong
       form, with protection against underflow and overflow.

ARGUMENTS
       I0    (input) INTEGER
	     First index.

       N0    (input) INTEGER
	     Last index.

       Z     (input) DOUBLE PRECISION array, dimension ( 4*N )
	     Z holds the qd array. EMIN is stored in Z(4*N0) to avoid an extra
	     argument.

       PP    (input) INTEGER
	     PP=0 for ping, PP=1 for pong.

       DMIN  (output) DOUBLE PRECISION
	     Minimum value of d.

	     DMIN1 (output) DOUBLE PRECISION Minimum value of d, excluding  D(
	     N0 ).

	     DMIN2  (output) DOUBLE PRECISION Minimum value of d, excluding D(
	     N0 ) and D( N0-1 ).

       DN    (output) DOUBLE PRECISION
	     d(N0), the last value of d.

       DNM1  (output) DOUBLE PRECISION
	     d(N0-1).

       DNM2  (output) DOUBLE PRECISION
	     d(N0-2).
