       ZCHKRQ

       Purpose:


            ZCHKRQ tests ZGERQF, ZUNGRQ and ZUNMRQ.

       Parameters

                     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.

           NM

                     NM is INTEGER
                     The number of values of M contained in the vector MVAL.

           MVAL

                     MVAL is INTEGER array, dimension (NM)
                     The values of the matrix row dimension M.

           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.

           NNB

                     NNB is INTEGER
                     The number of values of NB and NX contained in the
                     vectors NBVAL and NXVAL.  The blocking parameters are used
                     in pairs (NB,NX).

           NBVAL

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

           NXVAL

                     NXVAL is INTEGER array, dimension (NNB)
                     The values of the crossover point NX.

           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.

           NMAX

                     NMAX is INTEGER
                     The maximum value permitted for M or N, used in dimensioning
                     the work arrays.

           A
