NAME
       slasq6.f -

SYNOPSIS
   Functions/Subroutines
       subroutine slasq6 (I0, N0, Z, PP, DMIN, DMIN1, DMIN2, DN, DNM1, DNM2)
	   SLASQ6 computes one dqd transform in ping-pong form. Used by sbdsqr
	   and sstegr.

Function/Subroutine Documentation
   subroutine slasq6 (integerI0, integerN0, real, dimension( * )Z, integerPP,
       realDMIN, realDMIN1, realDMIN2, realDN, realDNM1, realDNM2)
       SLASQ6 computes one dqd transform in ping-pong form. Used by sbdsqr and
       sstegr.

       Purpose:

	    SLASQ6 computes one dqd (shift equal to zero) transform in
	    ping-pong form, with protection against underflow and overflow.

       Parameters:
	   I0

		     I0 is INTEGER
		   First index.

	   N0

		     N0 is INTEGER
		   Last index.

	   Z

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

	   PP

		     PP is INTEGER
		   PP=0 for ping, PP=1 for pong.

	   DMIN

		     DMIN is REAL
		   Minimum value of d.

	   DMIN1

		     DMIN1 is REAL
		   Minimum value of d, excluding D( N0 ).

	   DMIN2

		     DMIN2 is REAL
		   Minimum value of d, excluding D( N0 ) and D( N0-1 ).

	   DN

		     DN is REAL
		   d(N0), the last value of d.

	   DNM1

		     DNM1 is REAL
		   d(N0-1).

	   DNM2

		     DNM2 is REAL
		   d(N0-2).
