       DCHKGB

       Purpose:


            DCHKGB tests DGBTRF, -TRS, -RFS, and -CON

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

           NM

                     NNB is INTEGER
                     The number of values of NB contained in the vector NBVAL.

           NBVAL

                     NBVAL is INTEGER array, dimension (NNB)
                     The values of the blocksize NB.

           NNS

                     NNS is INTEGER
                     The number of values of NRHS contained in the vector NSVAL.

           NSVAL

                     NSVAL is INTEGER array, dimension (NNS)
                     The values of the number of right hand sides NRHS.

           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.
