COMPUTE RANKORDER

            [SIC\]COMPUTE OutVar RANKORDER InVar

        Compute  the order (sorting array) corresponding to the values in InVar,
        e.g.
          SIC> define real a[4] b[4]
          SIC> let a 10 15 12 9
          SIC> compute b rankorder a
          SIC> exa b
          B               is a real Array     of dimensions  4
             4.000000       1.000000       3.000000       2.000000

        InVar and OutVar are R*4 or R*8 variables, assumed to be 1-D  variables.
        This  can  be  used  e.g.  for statistical non-parametric tests like the
        Spearman test.
