       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

           !>          (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) =
           !>          .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used.
           !>
