       Purpose:


           !>
           !> CCKGSV tests CGGSVD:
           !>        the GSVD for M-by-N matrix A and P-by-N matrix B.
           !>

       Parameters
           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.
           !>

           PVAL

           !>          PVAL is INTEGER array, dimension (NP)
           !>          The values of the matrix row dimension P.
           !>

           NVAL

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

           NMATS

           !>          NMATS is INTEGER
           !>          The number of matrix types to be tested for each combination
           !>          of matrix dimensions.  If NMATS >= NTYPES (the maximum
           !>          number of matrix types), then all the different types are
           !>          generated for testing.  If NMATS < NTYPES, another input line
           !>          is read to get the numbers of the matrix types to be used.
           !>

           ISEED

           !>          ISEED is INTEGER array, dimension (4)
           !>          On entry, the seed of the random number generator.  The array
           !>          elements should be between 0 and 4095, otherwise they will be
           !>          reduced mod 4096, and ISEED(4) must be odd.
           !>          On exit, the next seed in the random number sequence after
           !>          all the test matrices have been generated.
           !>

           THRESH

           !>          THRESH is REAL
           !>          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.
           !>

           NMAX

           !>          NMAX is INTEGER
           !>          The maximum value permitted for M or N, used in dimensioning
