Purpose:

    !>
    !> DDRVGB tests the driver routines DGBSV, -SVX, and -SVXX.
    !>
    !> Note that this file is used only when the XBLAS are available,
    !> otherwise ddrvgb.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

    !>

    THRESH

    !>          THRESH is DOUBLE PRECISION

    !>          included in the output file if RESULT >= THRESH.  To have
    !>          every test ratio printed, use THRESH = 0.
    !>

    !>

    LAFB
