       Purpose:


            ZDRVGB tests the driver routines ZGBSV, -SVX, and -SVXX.

            Note that this file is used only when the XBLAS are available,
            otherwise zdrvgb.f defines this subroutine.

       Parameters
           DOTYPE

                     DOTYPE is LOGICAL array, dimension (NTYPES)
                     The matrix types to be used for testing.  Matrices of type j
                     (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
                     .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.

           NN

                     NN is INTEGER
                     The number of values of N contained in the vector NVAL.

           NVAL

                     NVAL is INTEGER array, dimension (NN)
                     The values of the matrix column dimension N.

           NRHS

                     NRHS is INTEGER
                     The number of right hand side vectors to be generated for
                     each linear system.

           THRESH

                     THRESH is DOUBLE PRECISION
                     The threshold value for the test ratios.  A result is
                     included in the output file if RESULT >= THRESH.  To have
                     every test ratio printed, use THRESH = 0.

           TSTERR

                     TSTERR is LOGICAL
                     Flag that indicates whether error exits are to be tested.

           A

                     A is COMPLEX*16 array, dimension (LA)

           LA

                     LA is INTEGER
                     The length of the array A.  LA >= (2*NMAX-1)*NMAX
                     where NMAX is the largest entry in NVAL.

           AFB

                     AFB is COMPLEX*16 array, dimension (LAFB)

           LAFB

                     LAFB is INTEGER
                     The length of the array AFB.  LAFB >= (3*NMAX-2)*NMAX
                     where NMAX is the largest entry in NVAL.

           ASAV

                     ASAV is COMPLEX*16 array, dimension (LA)

           B

                     B is COMPLEX*16 array, dimension (NMAX*NRHS)

           BSAV

                     BSAV is COMPLEX*16 array, dimension (NMAX*NRHS)

           X

                     X is COMPLEX*16 array, dimension (NMAX*NRHS)

           XACT

           S

                     S is DOUBLE PRECISION array, dimension (2*NMAX)

           WORK

                     WORK is COMPLEX*16 array, dimension
                                 (NMAX*max(3,NRHS,NMAX))

           RWORK

                     RWORK is DOUBLE PRECISION array, dimension
                                 (max(2*NMAX,NMAX+2*NRHS))

           IWORK

                     IWORK is INTEGER array, dimension (NMAX)

           NOUT

                     NOUT is INTEGER
                     The unit number for output.
